/**
* SECTION:gtkmain
* @Short_description: Library initialization, main event loop, and events
* @Title: Main loop and Events
* @See_also:See the GLib manual, especially #GMainLoop and signal-related
* functions such as g_signal_connect()
*
* Before using GTK+, you need to initialize it; initialization connects to the
* window system display, and parses some standard command line arguments. The
* gtk_init() macro initializes GTK+. gtk_init() exits the application if errors
* occur; to avoid this, use gtk_init_check(). gtk_init_check() allows you to
* recover from a failed GTK+ initialization - you might start up your
* application in text mode instead.
*
* Like all GUI toolkits, GTK+ uses an event-driven programming model. When the
* user is doing nothing, GTK+ sits in the main loop and
* waits for input. If the user performs some action - say, a mouse click - then
2014-02-05 18:07:34 +00:00
* the main loop wakes up and delivers an event to GTK+. GTK+ forwards the
* event to one or more widgets.
*
* When widgets receive an event, they frequently emit one or more
* signals. Signals notify your program that "something
2014-02-07 18:38:26 +00:00
* interesting happened" by invoking functions youve connected to the signal
* with g_signal_connect(). Functions connected to a signal are often termed
* callbacks.
*
* When your callbacks are invoked, you would typically take some action - for
* example, when an Open button is clicked you might display a
2011-01-06 14:06:24 +00:00
* #GtkFileChooserDialog. After a callback finishes, GTK+ will return to the
* main loop and await more user input.
2014-02-01 09:35:54 +00:00
*
* ## Typical main() function for a GTK+ application
*
* |[<!-- language="C" -->
* int
* main (int argc, char **argv)
* {
2018-01-03 16:10:21 +00:00
* GtkWidget *mainwin;
* // Initialize i18n support with bindtextdomain(), etc.
*
2018-01-03 16:10:21 +00:00
* // ...
*
* // Initialize the widget set
* gtk_init ();
*
* // Create the main window
* mainwin = gtk_window_new (GTK_WINDOW_TOPLEVEL);
*
* // Set up our GUI elements
*
2018-01-03 16:10:21 +00:00
* // ...
*
* // Show the application window
2017-01-19 09:02:04 +00:00
* gtk_widget_show (mainwin);
*
* // Enter the main event loop, and wait for user interaction
* gtk_main ();
*
* // The user lost interest
* return 0;
* }
* ]|
2014-02-01 09:35:54 +00:00
*
* Its OK to use the GLib main loop directly instead of gtk_main(), though it
* involves slightly more typing. See #GMainLoop in the GLib documentation.

This might seem like a large patch, but it isn't that bad, and nothing should break on Unix/X11. Win32 merge and general portability stuff: * acconfig.h,configure.in: Check for <sys/time.h>. * gdk/win32: New directory (actually, been there for a while). * gtk/fnmatch.c: Include <glib.h> for G_DIR_SEPARATOR, WIN32 and NATIVE_WIN32, and use these. Always case fold on Win32. No backslashed escapes on native Win32. * gtk/{gtk.def,makefile.msc}: New files. * gtk/Makefile.am: Add above new files. * gtk/{gtkaccelgroup,gtkbindings}.c: Include <string.h> instead of <strings.h>. * gtk/{gtkcalendar,gtkitemfactory,gtkpreview,gtkrc}.c: Include config.h. Protect inclusion of <sys/param.h>, <sys/time.h>, and <unistd.h> appropriately. * gtk/gtkdnd.c: Merge in Win32 version (which doesn't do much). Use ABS() (from <glib.h>) instead of abs(). * gtk/gtkfilesel.c: Moved Win32-specific includes after inclusion of gtk (and thus glib) headers, so that WIN32 will be defined. With MS C, include <direct.h> for mkdir prototype. * gtk/gtkitemfactory.c (gtk_item_factory_callback_marshal): Add some casts, needed by MS C. * gtk/{gtklayout,gtkplug}.c: Merge in Win32 version (which isn't implemented). * gtk/gtkmain.c: Include gdk/gdkx.h for GDK_WINDOWING. Include <X11/Xlocale.h> only on X11 platform, otherwise <locale.h>. Use G_SEARCHPATH_SEPARATOR_S and g_module_build_path. * gtk/gtkmain.h: Mark variables for export/import on Win32. * gtk/gtkrange.c (gtk_range_motion_notify): Set mods also in case the event is not a hint, or its window is not the slider. Needed on Win32, at least. * gtk/gtkrc.c: Include config.h and gdk/gdkx.h. Use <locale.h> unless on X11. Skip \r chars, too. Use G_DIR_SEPARATOR and G_SEARCHPATH_SEPARATOR(_S). Use g_path_is_absolute. On Win32, use a subdirectory of the Windows directory as gtk system configuration directory. * gtk/gtkselection.c: No chunks on Win32. * gtk/gtksocket.c: Not implemented on Win32. * gtk/gtkthemes.c (gtk_theme_engine_get): Use g_module_build_path. * gtk/makeenums.h: Include gdkprivate.h after gdk.h. * gtk/testrgb.c: Use dynamically allocated buffer. Use GTimers.

Updates. 2001-10-29 Tor Lillqvist <tml@iki.fi> * README.win32: Updates. * gtk-zip.sh.in: New file, used to build distribution package for Windows. * gdk/gdkglobals.c: Mark gdk_threads_mutex for DLL export when applicable with GDKVAR. * gtk/gtk.def: Update. * gtk/gtkfilesel.c: Include <winsock.h> (if available) for gethostname(). * gtk/gtkmain.c * gtk/gtkrc.c: (Win32) Save actual DLL name for later use in DLL entry function. Avoid hardcoded paths GTK_LIBDIR, GTK_SYSCONFDIR, GTK_DATA_PREFIX and GTK_LOCALEDIR, instead add functions that call g_win32_get_package_installation_subdirectory() with the actual DLL name saved above. Redefine above directory name macros to call these functions. Remove some ifdefs. * gtk/maketypes.awk: Output GTKTYPEBUILTINS_VAR (that marks variable for export on Win32) also to the _vars file. Changes for autoconfiscated build on Win32, and addition of Win32 backend to the related files: * configure.in: Like in GLib, set LT_CURRENT_MINUS_AGE for use when forming DLL name in some files. Set MS_LIB_AVAILABLE is lib.exe is available. Call AC_LIBTOOL_WIN32_DLL. Set PLATFORM_WIN32, OS_WIN32 and USE_WIN32 automake conditionals. Add win32 target, using pangowin32. Don't use the -export-symbols-regex option on Win32, we use .def files to list exported symbols. Check <winsock.h> (for gethostname() in gtkfilesel.c). Enclose nested AC_CHECK_* macros in brackets to prevent premature m4 expansion. * acconfig.h: Add HAVE_WINTAB. * gdk/Makefile.am: Add libgdk-win32-1.3.la target and associated macros and rules. Use -no-undefined on Win32. Use gdk.def file. If MS_LIB_AVAILABLE, build MS import library. Install the import libraries. If HAVE_WINTAB, link with the Wintab library. * gtk/Makefile.am: Add libgtk-win32-1.3.la target and associated macros and rules. Use -no-undefined on Win32. Use gtk-win32.def file. Install import libraries.

Integrate Erwann Chenede's multihead changes for the gtk/ directory. Mon Apr 29 18:28:00 2002 Owen Taylor <otaylor@redhat.com> Integrate Erwann Chenede's multihead changes for the gtk/ directory. * gtk/gtkclipboard.[ch]: Add gtk_clipboard_get_for_display(), make internals multihead aware. * gtk/gtkcolorsel.[ch]: Add gtk_color_selection_set_change_palette_with_screen_hook () [ugh!] make up for non-multihead safety of gtk_color_selection_set_change_palette_hook() * gtk/gtkinvisible.[ch] gtk/gtkmenu.[ch] gtkwindow.[ch]: Add gtk_{invisible,menu,window}_set_screen(); add "screen" properties for GtkWindow and GtkMenu. * gtk/gtkplug.[ch]: Add gtk_plug_construct_for_display(), gtk_plug_new_for_display(). Multihead fixes. * gtk/gtkselection.[ch]: Add gtk_selection_owner_set_for_display(), make internals multihead aware. * gtk/gtksettings.[ch]: Add gtk_settings_get_for_screen(), get rid of now-useless gtk_settings_constructor(). * gtk/gtkstyle.[ch]: Add gtk_style_get_font_for_display(), fix check/radio button indicators bitmap handling to be multihead safe. * gtk/gtkwidget.[ch]: Add gtk_widget_get_screen(), gtk_widget_has_screen(), gtk_widget_get_display(), gtk_widget_get_clipboard(), gtk_widget_get_root_window(). * gtk/gtkbindings.c gtk/gtkbutton.c gtk/gtkclist.c gtk/gtkcombo.c gtk/gtkctree.c gtk/gtkdnd.c gtk/gtkfilesel.c gtk/gtkgamma.c gtk/gtkhandlebox.c gtk/gtkhsv.c gtk/gtkimcontext.c gtk/gtklabel.c gtk/gtklist.c gtk/gtkmain.c gtk/gtkmenuitem.c gtk/gtkmenushell.c gtk/gtknotebook.c gtk/gtkoldeditable.c gtk/gtkoptionmenu.c gtk/gtkpaned.c gtk/gtkpreview.c gtk/gtksocket.c gtk/gtktext.c gtk/gtktextbuffer.c gtk/gtktextview.c gtk/gtktipsquery.c gtk/gtktooltips.c gtk/gtktreeview.c gtk/gtktreeviewcolumn.c: misc mechanical multihead-safety fixes. * gtk/gtkclipboard.c: Use a GtkImage rather than a pixmap for the dropper, look up the color palette only at realization time, other multihead fixes. * gtk/gtkcombo.c (gtk_combo_unrealize): Popdown the list when unrealizing. * gtk/gtkentry.c: Only claim ownership of the primary selection when realized, misc multihead fixes. * gtk/gtkfontsel.c: Only fill in fonts when attached to a screen, fix gtk_font_selection_get_font() for multihead. * gtk/gtkgc.c: make the depth => drawable hash per-screen. * gtk/gtkinvisible.c: Add a constructor that realizes the widget, so we get a realized widget with g_object_new() as well gtk_invisible_new() as before. * gtk/gtkmain.c: Get rid of unused gtk_visual/gtk_colormap variables. * gtk/gtktextdisplay.c: Add warnings if stipple bitmaps are used on the wrong screen. * gtk/gtktoolbar.c: Make handling of GtkSettings-based layout read properties and connect to settings when the screen is changed, rather than on init/finalize. * gtk/gtkwindow.c: Fix icon handing to be multihead safe ... default icon pixmaps/mask are only shared between windows on the same screen. Misc multihead fixes. Sat Apr 27 13:49:53 2002 Owen Taylor <otaylor@redhat.com> * gtk/gtkclipboard.c (gtk_clipboard_get_for_display): Update docs to reference GDK_SELECTION_CLIPBOARD rather GDK_NONE. 2002-04-29 Alex Larsson <alexl@redhat.com> * gdk/linux-fb/gdkproperty-fb.c (gdk_property_get): Fix silly bug, noticed by Sven Neumann.

/**
* gtk_main_do_event:
* @event: An event to process (normally passed by GDK)
*
* Processes a single GDK event.
*
* This is public only to allow filtering of events between GDK and GTK+.
* You will not usually need to call this function directly.
*
* While you should not call this function directly, you might want to
* know how exactly events are handled. So here is what this function
* does with the event:
*
* 1. Compress enter/leave notify events. If the event passed build an
* enter/leave pair together with the next event (peeked from GDK), both
* events are thrown away. This is to avoid a backlog of (de-)highlighting
* widgets crossed by the pointer.
*
2014-02-07 18:32:47 +00:00
* 2. Find the widget which got the event. If the widget cant be determined
* the event is thrown away unless it belongs to a INCR transaction.
*
* 3. Then the event is pushed onto a stack so you can query the currently
* handled event with gtk_get_current_event().
*
* 4. The event is sent to a widget. If a grab is active all events for widgets
* that are not in the contained in the grab widget are sent to the latter
* with a few exceptions:
* - Deletion and destruction events are still sent to the event widget for
* obvious reasons.
* - Events which directly relate to the visual representation of the event
* widget.
* - Leave events are delivered to the event widget if there was an enter
* event delivered to it before without the paired leave event.
* - Drag events are not redirected because it is unclear what the semantics
* of that would be.
*
* 5. After finishing the delivery the event is popped from the event stack.

Sun Sep 26 19:44:34 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkcontainer.c (gtk_container_queue_resize): We may be queueing a resize on a toplevel container between the time we show it and when we map it. So, we need to test GTK_WIDGET_VISIBLE() for toplevels, and only use GTK_WIDGET_DRAWABLE() for child windows. Thu Sep 23 16:41:03 1999 Owen Taylor <otaylor@redhat.com> * gtk/Makefile.am (LDADDS): Add GDK_WLIBS to LDADDS (fixes bug #2144) Fri Sep 24 00:51:45 1999 Tim Janik <timj@gtk.org> * gtk/gtkcontainer.c (gtk_container_queue_resize): check for container DRAWABLE (instead of VISIBLE), so we don't queue resizes on non-toplevel containers.

Tue Sep 14 18:29:47 1999 Tim Janik <timj@gtk.org> * gtk/gtkcontainer.c: added new widget level method gtk_container_set_reallocate_redraws() and a GtkContainer flag reallocate_redraws : 1 to reflect the setting, exported this through the argument system as a boolean ::reallocate_redraws. * gtk/gtkwidget.c (gtk_widget_size_allocate): when queueing redraws on the widget because the allocation changes, do so as well for widget->parent if the parent has reallocate_redraws set to TRUE. with that containers requesting reallocation redraws get automatically redrawn if their children changed allocation (this unfortunately affects also other children that didn't change allocation, but we cannot work around that before 1.3). Tue Sep 14 18:23:01 1999 Tim Janik <timj@gtk.org> * gtk/gtkwidget.c (gtk_widget_idle_draw): only emit ::draw if width _and_ height are >0 (not _or_). * gtk/gtktable.c (gtk_table_remove): use gtk_widget_queue_resize() instead of gtk_container_queue_resize(), which is a core gtk internal function (must have been on crack when i queued that). * gtk/gtkprivate.h: added new private flag GTK_FULLDRAW_PENDING, so we can check more reliably if we want to discard expose events. * gtk/gtkwidget.c: added setting/unsetting of the GTK_FULLDRAW_PENDING flag. * gtk/gtkwidget.c (gtk_widget_event): don't discard synthesized exposes, we simply trust these events. for deciding whether to discard exposes, check GTK_FULLDRAW_PENDING instead of RESIZE_PENDING. Mon Sep 13 15:01:21 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_queue_clear_area): Ignore queues of areas that are completely off screen. * gtk/gtkwidget.c (gtk_widget_idle_draw): Fix broken logic for handleboxes. * gtk/gtkwidget.c (gtk_widget_queue_draw_data): Add santity check on width/height. Mon Sep 13 02:22:47 1999 Tim Janik <timj@gtk.org> * gtk/Makefile.am: backed out Raja's recent VPATH build "improvements", we are fine with using $@ the way we do (if we actually encounter brokeness with $@ in VPATH builds because of additional path prefixes, we need to use $(@F) actually). Mon Sep 13 01:34:53 1999 Tim Janik <timj@gtk.org> * gtk/gtksignal.c: renamed two variables, hopefully didn't introduce short lived bugs, that would allow language bindings to do surgeries to our guts. Fri Sep 10 15:22:50 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkwindow.c (gtk_window_size_allocate): Fix typo where comparison was being done against an uninitialized value causing intermittant results depending on compiler flags. Also make it clearer that we aren't ever initializing the child as 0x0 (though this will be caught in gtk_widget_size_allocate()) Fri Sep 10 10:06:56 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkwindow.c (gtk_window_set_transient_for): Move gtk_window_unset_transient_for() call after we do checks involving the old transient parent. [ From Lance Capser <lmc@cyberhighway.net> ] 1999-09-07 Raja R Harinath <harinath@cs.umn.edu> * gtk/Makefile.am (gtk.defs): Go back to using `touch' to create an empty file. Mon Sep 6 00:11:56 1999 Lars Hamann <lars@gtk.org> * gtk/gtkctree.c (gtk_ctree_is_ancestor): return FALSE if node has no children. (Reported by: Chris Rogers <gandalf@pobox.com>) 1999-09-03 Raja R Harinath <harinath@cs.umn.edu> * gtk/Makefile.am (gen_sources): Improve VPATH builds. `$@' is valid only in the build dir, not after we've done `cd $srcdir'. Also use `test -f' instead of less portable `test -e'. Fri Sep 3 15:59:56 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtktext.c (correct_cache_insert): Rewrite for simplicity, and hopefully correctness. (Fixes bug #1322, which was a segfault when on some insertions with the properties around the insertion set up just wrong.) * gtk/gtktext.c (gtk_text_adjustment): When we receive a "changed" signal, clamp the new value to the adjustment bounds to avoid segfaulting if someone tries to change the adjustment to a bogus value. (Bug #1795) Thu Sep 2 16:33:59 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkmain.c: Ignore unexpected destroy notifies for children, for toplevel windows handle them like delete_event. * gtk/gtkplug.c: Add an unrealize handler so that we unref plug->socket_window when we are done with it. Fri Sep 3 14:52:54 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtktext.c (clear_area): Fix stupid signedness problem that was causing background to sometimes be misaligned. Fri Sep 3 12:26:33 1999 Owen Taylor <otaylor@redhat.com> [ Fixes pointed out by Ettore Perazzoli <ettore@comm2000.it> ] * gtk/gtkmenu.c (gtk_menu_position): Make sure we never position menus with negative x, y, since gtk_widget_set_uposition() can't handle that. * gtk/gtkmenuitem.c (gtk_menu_item_position_menu): Modify the positioning code a bit so that we always put the top-left corner onscreen. (This is for UI reasons, gtk_menu_position() now takes care of gtk_widet_set_uposition() brokeness.) Fri Sep 3 03:06:30 1999 Tim Janik <timj@gtk.org> * gtk/Makefile.am: fixed up things for -jx, x > 1. Sun Sep 5 08:48:51 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_modify_style): Ref the RC style that is passed in. The lack of the ref before was a bug. If people worked around this bug, this will introduce a slight memory leak in their code. The code should typically look like: rc_style = gtk_rc_style_new (); [...] gtk_widget_modify_style (widget, rc_style); gtk_rc_style_unref (rc_style); * gtk/gtkwidget.c (gtk_widget_modify_style): Reset the style if it was already set. * gtk/gtkwidget.c (gtk_widget_set_name): Only set the style if it was set before. Thu Sep 2 19:02:37 1999 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (main): Add a check to see if we are being run from the correct directory and to quit nicely if we are not. * gtk/gtkrc.c (gtk_rc_slist_remove_all): Make function static. Thu Sep 2 23:00:03 1999 Tim Janik <timj@gtk.org> * gtk/gtkenums.h (GtkWindowPosition): added GTK_WIN_POS_CENTER_ALWAYS. * gtk/gtkwindow.c: queue resizes unconditionally (gtk_widget_queue_resize will figure what to do if the window is not realized). (gtk_window_move_resize): only recenter the window for GTK_WIN_POS_CENTER_ALWAYS. (gtk_window_compute_reposition): handle GTK_WIN_POS_CENTER_ALWAYS in the same way as GTK_WIN_POS_CENTER. Thu Sep 2 22:39:27 1999 Tim Janik <timj@gtk.org> * gtk/gtkwindow.c (gtk_window_reposition): check for the last position with (!(info->last_flags & GDK_HINT_POS)) instead of (!info->last_flags & GDK_HINT_POS). * gtk/gtkwindow.c (gtk_window_move_resize): constrain new_width and new_height unconditionally, because we use these values even if !default_size_changed && !hints_changed. comented the (default_size_changed || hints_changed) case with respect to resize rejects from the window manager. * gtk/gtkwindow.c (gtk_window_move_resize): save info->last values in the zvt condition hack, since this includes the window hints, set the hints after the handling_resize case. * gtk/gtkwindow.c (gtk_window_show): constrain the default size that a window is initially shown with to the geometry. Thu Sep 2 07:38:56 1999 Tim Janik <timj@gtk.org> * gtk/gtkwindow.c (gtk_window_move_resize): s/size_changed/default_size_changed/g so i know what's really going on (frying brain on smaller flame now). Thu Sep 2 05:47:47 1999 Tim Janik <timj@gtk.org> * gtk/gtkwindow.c (gtk_window_move_resize): queue a new resize if we have size_changed upon handling_resize. this is a gross workaround for the broken zvt widget and should be removed in 1.3 again (search for FIXME). Owen provided an accurate comment for this: /* We could be here for two reasons * 1) We coincidentally got a resize while handling * another resize. * 2) Our computation of size_changed was completely * screwed up, probably because one of our children * is broken. It's probably a zvt widget. * * For 1), we could just go ahead and ask for the * new size right now, but doing that for 2) * might well be fighting the user (and can even * trigger a loop). Since we really don't want to * do that, we requeue a resize in hopes that * by the time it gets handled, the child has seen * the light and is willing to go along with the * new size. (this happens for the zvt widget, since * the size_allocate() above will have stored the * requisition corresponding to the new size in the * zvt widget) * * This doesn't buy us anything for 1), but it shouldn't * hurt us too badly, since it is what would have * happened if we had gotten the configure event before * the new size had been set. */ Wed Sep 1 20:46:11 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkrc.c: deal properly with the fact that RC style lists may include rc styles more than once. * gtk/gtkrc.c (gtk_rc_append_pixmap_path): Removed unused static function. * gtk/gtkrc.c (gtk_rc_find_pixmap_in_path): Keep a stack of directories of RC files currently being parsed and implicitely add them to pixmap path. This fixes a bug where the directory would get appended then overwritten by pixmap_path declarations. (bug #1462, from Peter Wainright <prw@wainpr.demon.co.uk>) * gtk/gtkthemes.c (gtk_theme_engine_unref): Call theme's exit function. (Patch from Peter Wainwright, bug #1454) * gtk/gtkradiomenuitem.c (gtk_radio_menu_item_destroy): Add a destroy() handler to take care of removing group for menu item. (Fixes bug #1197) * gtk/gtkwidget.c (gtk_widget_size_request): Fixed thinko in warning message. Wed Sep 1 21:27:42 1999 Tim Janik <timj@gtk.org> * gtk/gtkwindow.c (gtk_window_move_resize): don't require a server roundtrip to figure window's width and height, since we know that anyways from widget->allocation. Wed Sep 1 12:37:44 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkwindow.c (gtk_window_move_resize): Compute the hints after we request the new size. Wed Sep 1 10:38:37 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkwindow.c (gtk_window_compute_hints): Removed GTK_WIDGET_REALIZED() assertion - we can compute the hints before we are realized. * gtk/gtkwindow.c (gtk_window_move_resize): Reorder hint changing so that we have a value of hints_changed when we decide whether to constrain the window size. * gtk/gtkwindow.c (gtk_window_move_resize): Spelling fix. * gtk/gtkwindow.c (gtk_window_constrain_size): cleanups, change back to G_MAXINT. Wed Sep 1 06:54:59 1999 Tim Janik <timj@gtk.org> * gtk/gtkwindow.c (gtk_window_get_geometry_info): zero initialize new GtkWindowGeometryInfo, so fields like GdkGeometry geometry contain uncluttered values. (gtk_window_compute_hints): simply assert that window is realized and that geometry_info is valid, since we rely on this anyways. (gtk_window_constrain_size): major cleanups to the code. if (flags & GDK_HINT_BASE_SIZE) use geometry's base width and height for the base size, instead of the minimums. use 32767 as max width and height (like in gtkwindow.c) instead of G_MAXINT. Wed Sep 1 04:41:25 1999 Tim Janik <timj@gtk.org> * cleaned up the GtkContainer.need_resize flag handling mess, we only need to force resize requests when we were prematurely realized, or our widget tree was modified when we were temporarily hidden. handling these cases directly upon showing the window (i.e. while the GdkWindow is still unmapped) avoids the need to wait for a configure event response and therefore makes the GUI more snappier and avoids blank windows during the roundtrip. * gtk/gtkwidget.c: (gtk_widget_hide): (gtk_widget_show): don't queue resizes on toplevels, they know how to deal with matters. * gtk/gtkcontainer.c (gtk_container_queue_resize): set the ->need_resize flag directly for not visible resize containers and spare us unecessary signal emissions. * gtk/gtkwindow.c: (gtk_window_realize): if we need to enforce premature size allocation, queue a container resize so we are correctly resized later on. (gtk_window_init): (gtk_window_size_request): don't freak around with the ->need_resize flag, gtk_container_queue_resize() will care about that. (gtk_window_show): handle initial resizing issues here, we can handle matters better in this place, especially since we know that our GdkWindow is still unmapped. (gtk_window_move_resize): don't care about ->need_resize at all. handle size changes properly that occoured while we waited for a configure event. Tue Aug 31 15:58:46 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkwidget.c (gtk_widget_set_uposition): * gtk/gtkwindow.[hc] (gtk_window_reposition): Move the hint setting code from gtk_widget_set_uposition to here; set the hints so that we respect any previously set geometry hints. * gtk/gtkwindow.c (gtk_window_compute_reposition): Don't change the window hints here or move the window here, let that happen in gtk_window_move_resize(). Tue Aug 31 06:58:52 1999 Tim Janik <timj@gtk.org> * gtk/gtkwidget.c (gtk_widget_event): when discarding exposes due to already queued resizes (and therefore redraws) on a widget, check its anchestry as well. * gtk/gtkcontainer.c: (gtk_container_queue_resize): clear resize widgets for resize containers before aborting prematurely. this is especially important for toplevels which may need imemdiate processing or their resize handler to be queued. (gtk_container_dequeue_resize_handler): added new internal function for gtkwindow.c. * gtk/gtkwindow.c (gtk_window_move_resize): if we are resizing due to a configure event, take possible changes in window position into account as well. if we request a new window size, queue up a resize handler that will last until the configure event response arrives. combined the ->need_resize case (initial show) with the general size (hints) changed case and added even more comments. if !auto_shrink, only revert to the old allocation if the new size is smaller than the current allocation. Tue Aug 31 11:55:20 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkwindow.c (gtk_window_set_arg, gtk_window_set_policy, gtk_window_set_geometry_hints gtk_window_set_default_size): When hints are set, queue a resize so that the hints will be eventually reset on the toplevel. * gtk/gtkwindow.c (gtk_window_show): Use gtk_window_compute_default_size(). Clear the need_resize flag on the initail map so that we don't unnecessarily trigger the resize code. * gtk/gtkwindow.c (gtk_window_move_resize): Split apart into separate functions. Compare the hints we are setting with what we set last time so that we can accurately tell when we need to reset the hints. * gtk/gtkwindow.c (gtk_window_compute_default_size): New function to figure out the size from requisition and default_size. * gtk/gtkwindow.c (gtk_window_constrain_size): Function from fvwm to constrain a size to the geometry hints. * gtk/gtkwindow.c (gtk_window_compare_hints): New function to compare two sets of geometry hints. * gtk/gtkwindow.c (gtk_window_compute_hints): Renamed from gtk_window_set_hints(), just compute the hints, don't set them. * gtk/gtkwindow.c (gtk_window_compute_reposition): Move code from gtk_window_move_resize() to separate function, rationalize a bit. Tue Aug 31 13:05:03 1999 Owen Taylor <otaylor@redhat.com> * gtkrc.h: Move the ref_count member out of the GtkRcStyle structure into a new private structure. * gtkrc.c: Split GtkRcStyle into public/private. In the private part, add a list of pointers to the RcStyle lists this RcStyle participates in. * gtkrc.c: When a RcStyle is free, remove all lists referencing it from the realized_style_ht hash, and free those lists. * gtk/gtkrc.c (gtk_rc_clear_styles): Don't call gtk_rc_init(), since that adds the default styles to the list of parsed RC files again. * gtk/gtkrc.c: Use gtk_rc_style_find() consistently. Thu Aug 26 14:14:42 1999 Tim Janik <timj@gtk.org> * gtk/gtkwidget.c (gtk_widget_size_allocate): reactivated the sanity checks that ensure that a widget's allocation is at least 1 in width and height. (GNOME note: this doesn't affect old panel code anymore, because GtkSocket will request width and height of at least 1 since Fri Jul 23). * gtk/gtkwindow.c (gtk_window_realize): if the widget hasn't been allocated yet (happens if the user realizes the window prematurely), size request and allocate it. (gtk_window_size_allocate): guard against guint underflows. Wed Aug 25 19:01:36 1999 Lars Hamann <lars@gtk.org> * gtk/Makefile.am (gtk_built_sources): reordered stamp-gtk.defs in gtk_built_sources, so gtk.defs gets built prior to all other sources. Mon Aug 23 19:11:17 1999 Tim Janik <timj@gtk.org> * gtk/Makefile.am: invoke indent on gtkmarshal.*. rewrote source generation rules, use COPYING as oldest source tag for a piggyback rule to generate all sources from (don't touch it ;). major cleanups, strip spaces on build rules for GNU Make. * gtk/genmarshal.pl: don't operate on hardcoded filenames but take source and target files from commandline arguments. don't invoke indent. Sat Aug 21 14:07:36 1999 Lars Hamann <lars@gtk.org> * gtk/gtknotebook.c (gtk_notebook_real_switch_page): queue_resize notebook after switch to avoid drawing problems. (Bug#856 Reported by: Theodore Roth <troth@netmagic.net>) (gtk_notebook_pages_allocate): don't map not visible tab_labels, show them instead. (Bug#1805 Reported by: Dave Cole <dave@dccs.com.au>) Sat Aug 21 14:07:36 1999 Lars Hamann <lars@gtk.org> * gtk/gtknotebook.c (gtk_notebook_real_switch_page): queue_resize notebook after switch to avoid drawing problems. (Bug#856 Reported by: Theodore Roth <troth@netmagic.net>) (gtk_notebook_pages_allocate): don't map not visible tab_labels, show them instead. (Bug#1805 Reported by: Dave Cole <dave@dccs.com.au>) Wed Aug 18 09:20:10 1999 Tim Janik <timj@gtk.org> * gtk/gtkwindow.c: we use window->need_resize from configure_event now, to indicate that the gtkwindow should keep its allocation (e.g. because the user resized the window through window manager handles). resize_count is now reliably used to figure whether we got the allocation we requested from the window manager. configure events get queued as resizes now, the real stuff (size computation and allocation) now only goes on in gtk_window_move_resize(). GtkWindow's requisition now contains its *real* requisition (like all other widgets), *not* taking usize into account. geometry_info->last_{width|height} is now updated from set_hints() only so it always contains the last hints we set for the window manager. made some event handlers return TRUE instead of FALSE. the overall code should be much more straight forward now, and the significant code portions are accompanied by comments now. (gtk_window_set_hints): removed requisition argument and made it fetch the requisition through gtk_widget_get_child_requisition. we also don't move the gdkwindow here anymore, gtk_window_move_resize() does that now. (gtk_window_show): ensure that the widget is realized before calling gtk_container_check_resize() (and thus gtk_window_move_resize()), also ensure that we got properly size requested and allocated before realization. (gtk_window_configure_event): ignore plain window moves, or reallocate the widget tree through the resize queue otherwise. (gtk_window_move_resize): mostly rewrote this function to figure window manager hints more reliably, coalesce window moves and resizes to reduce configure events and do actuall size allocations. Tue Aug 17 07:43:04 1999 Tim Janik <timj@gtk.org> * gtk/gtkwidget.c (gtk_widget_event): discard expose events for widgets that have a resize pending, because a redraw is already queued for them. * gtk/gtkcontainer.c: removed ugly connect_to ::size_allocate signal hack to clear resize_widgets. * gtk/gtkwidget.c (gtk_widget_size_allocate): call clear_resize_widgets for resize containers prior to size allocation. (this is also a bit ugly, but avoids side effects for stopped emissions and is thus more reliable). (gtk_widget_unparent): removed disconnect call for clear_resize_widgets. * gtk/gtktooltips.c (gtk_tooltips_paint_window): renamed this function from gtk_tooltips_expose, as we connect to ::expose_event *and* ::draw now. 1999-08-18 Federico Mena Quintero <federico@redhat.com> * gtk/gtkselection.c (gtk_target_list_ref): Added missing sanity checks. (gtk_target_list_unref): Likewise. * gtk/gtkthemes.c (gtk_theme_engine_unref): Likewise. Tue Aug 17 15:47:07 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkcolorsel.c (gtk_color_selection_draw_value_bar): guard against division by zero. (Fixes bug #1339) Tue Aug 17 10:56:49 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkentry.c (gtk_move_{forward,backward}_word): Prevent the trivial leak of information of allowing word motion when the entry is not visible. Tue Aug 17 10:28:52 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (gtk_file_selection_fileop_error): Propagate modality to error dialog as well as confirmation dialogs. (Bug #1803, reported by Rosanna Wing Sze Yuen) Wed Aug 11 01:04:57 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtktreeitem.c (gtk_tree_item_draw_lines): Honor tree->view_lines. (gtk-guy-990611-3.patch: Guy Harris <guy@netapp.com>) * gtk/Makefile.am (install-data-local): Solaris apparently has various troubles with ln -f; use rm first instead. (gtk-guy-990611-2.patch: Guy Harris <guy@netapp.com>) 1999-07-30 Raja R Harinath <harinath@cs.umn.edu> * gtk/Makefile.am (stamp-m): Don't `mv' from builddir to srcdir, use `cp' followed by `rm' (the `rm' was already there). July 30, 1999 Elliot Lee <sopwith@redhat.com> * configure.in: Fix autoconf warnings about cross compilation by trying to provide sane defaults for AC_TRY_RUN. * gtk/Makefile.am: If we refer to gtkmarshal.[ch] in $(srcdir), put them into $(srcdir) when generated. Also add a dependency of gtksignal.h on gtkmarshal.h for -j builds. * gtk/gtk(dnd,style,gamma).c: Minor warning fixes. Wed Jul 28 09:29:19 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkmain.c (gtk_main_iteration_do): Added missing GDK_THREADS_{LEAVE,ENTER} pair. (From Paul Fisher <pnfisher@redhat.com>) Fri Jul 23 01:00:15 1999 Tim Janik <timj@gtk.org> * gtk/gtksocket.c (gtk_socket_size_request): asure that the requested width and height are always >0 (owen). Fri Jul 23 00:00:47 1999 Tim Janik <timj@gtk.org> * gtk/gtkwidget.c (gtk_widget_size_allocate): backed out my recent change that assured that a widget's allocated with and height are always >1, since this breaks *buggy* panel code. unfortunately this back-breaks the gimp's color selector. * gtk/gtkdrawingarea.c (gtk_drawing_area_size_allocate): asure that our allocation is always >0 in width and height, before sending the configure event; this is a *gross* hack to get the gimp back to work. * marked both cases with TODO-1.3 Wed Jul 21 15:47:39 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtktext.c: Don't display wrap indicators when text is not editable and word wrap is on. Wed Jul 21 08:21:40 1999 Tim Janik <timj@gtk.org> * gtk/gtkitemfactory.c (gtk_item_factory_create_item): special case option menus here as they are not derived from menu shell, assure that the option menu has a menu we can add items to. Tue Jul 20 23:29:48 1999 Tim Janik <timj@gtk.org> * gtk/gtknotebook.c (gtk_notebook_page_allocate): convert allocation-> width/height to (gint) before calculations and check against < 0 to avoid guint wraparounds. Sun Jul 18 00:35:49 1999 Tim Janik <timj@gtk.org> * gtk/gtkwidget.c (gtk_widget_size_allocate): ensure that the allocated width and height is never zero. sanity check both dimensions against 32767 and issue a warning if the allocation is greater than that. Wed Jul 7 15:03:30 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkmain.c (gtk_events_pending): Unlock around call to g_main_pending() as well. Wed Jul 7 14:59:01 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkmain.c (gtk_main_iteration): Unlock around call to g_main_iteration() - since that will regrab GTK+ lock to process events. Thu Jul 1 15:01:55 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkwindow.c - Regularize with the rest of GTK+ by making widget->requisition not reflect the set_usize() - Always recompute geometry hints, then check if they changed before sending them to the X server. The previous checks for changes would fail in a number of circumstances. Thu Jul 1 11:55:59 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkstyle.c: Include <stdlib.h> for strcmp(). Wed Jun 30 19:26:36 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkdnd.c: - Code cleanups - Instantaneously update on modifier key presses - Allow cancellation of the drag with Escape. Tue Jun 29 17:04:09 1999 Owen Taylor <otaylor@redhat.com> * gtk/testgtk.c (create_handle_box): Set the policy to auto_shrink - otherwise the appearance is rather strange when flipping between horizontal and vertical. Mon Jun 28 09:29:52 1999 Tim Janik <timj@gtk.org> * gtk/gtkwindow.c: add ::default_width and ::default_height arguments. (gtk_window_set_default_size): don't change a value if it's < 0. queue a resize. Sun Jun 27 11:00:33 1999 Tim Janik <timj@gtk.org> * gtk/gtktext.c (gtk_text_insert): don't segfault on NULL inserts. Mon Jun 28 12:08:25 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkfilesel.c (cmpl_completion_fullname): Don't add an extra "/" when concating "/" + filename. (From Matt Grossman <mattg@oz.net>) Mon Jun 28 10:57:12 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkctree.c (draw_cell_pixmap): Reset clip mask for fg_gc if we set it for drawing pixmap.

(gtk_editable_delete_text): same here. (gtk_editable_class_init): set widget_class->activate_signal after editable_signals[ACTIVATE] has been created. Wed Apr 7 22:59:47 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkpaned.c (gtk_paned_set_position): Don't clamp position here prematurely -- we might not have the right ->min_position and ->max_position yet.

Sat Mar 27 23:32:13 1999 Tim Janik <timj@gtk.org> * gtk/gtkarg.[hc]: added functions from GLE, gtk_arg_reset() to free the value and reset type to GTK_TYPE_INVALID, and gtk_arg_values_equal() to compare two argument values. added gtk_arg_to_valueloc() to set a variable from an arg through its location (pointer). * gtk/gtkobject.[hc]: implemented gtk_object_get() in terms of gtk_object_arg_get() and gtk_arg_to_valueloc(), floats are collected as gfloat*, uchars are collected as guchar*, ints are collected as gint*, etc... Mon Mar 29 17:45:47 1999 Owen Taylor <otaylor@redhat.com> * gtk/gtkaccelgroup.c gtk/gtkgtkbindings.c: Include <string.h> instead of <strings.h>. * gtk/gtkstyle.c: Fix double include of gtkthemes.h (actually, a lot more duplicate includes occur if you trace through the sequence of #include's) gtk-jbb-990320-0: John Bley, jbb6@acpub.duke.edu Mon Mar 29 17:02:58 1999 Owen Taylor <otaylor@redhat.com> Patches from Akira Higuchi <a-higuti@math.sci.hokudai.ac.jp> gtk-a-higuti-990322-[0-3] * configure.in: Fix confusion between GTK_LOCALE_[C]FLAGS that was causing -DX_LOCALE not to work. * gtk/gtkrc.c (gtk_rc_init): X_LOCALE will never have LC_MESSAGES defined Thu Mar 25 12:38:31 1999 Tim Janik <timj@gtk.org> * gtk/gtkrc.c (gtk_rc_append_default_module_path): get $HOME from g_get_home_dir() (gtk-pmc-990123-0.patch.gz). * gtk/gtkwindow.c (gtk_window_key_press_event): feature keypad up/down/ left/right as well (gtk-michael-980726-0.patch.gz). * gtk/gtklabel.[hc]: bunch of miscellaneous cleanups, such as s/0/NULL/ for pointer values, use gchar instead of char. fixed uline allocation leaks, changed the allocation pattern so we use G_ALLOC_AND_FREE mem chunks instead of G_ALLOC_ONLY. (gtk_label_size_request): always alter requisition as passed and leave widget->requisition alone. (gtk_label_set_text): allow NULL strings. (gtk_label_new): likewise.

(gtk_box_expose): only send exposes to drawable children. * gtk/gtkhscale.c (gtk_hscale_draw): * gtk/gtkvscale.c (gtk_vscale_draw): hm, this is an ugly one. we first compute the size of our trough area here (window relative) and then check intersection with the draw_area which is parent relative because we're a NO_WINDOW widget, so we need to offset the trough area by allocation.x and allocation.y before the check. (this must not be done for the background area though, since that's already computed parent relative). Mon Mar 22 00:41:39 1999 Lars Hamann <lars@gtk.org> * gtk/gtkclist.c (gtk_clist_unrealize): unmap clist if neccessary, unrealize title buttons.

*
* Events received by GTK+ from GDK normally begin in gtk_main_do_event().

* the event may be propagated; if so, this function is used.
*
* gtk_propagate_event() calls gtk_widget_event() on each widget it
* decides to send the event to. So gtk_widget_event() is the lowest-level

* higher-level, and gtk_main_do_event() is the highest level.
