Mon Nov 17 1997 Jay Painter * gtkviewport.c: Raph's Mon, 10 Nov 1997 patch to gtk-list to fix some viewport bugs Mon Nov 17 1997 Jay Painter * gtk/gtkwidget.c: gtk-ajaborsk-971016-2 A little patch again to prevent user to use gtk_widget_set_events() when a widget is already realized. In this case, the gtk_widget_set_events() doesn't work. Mon Nov 17 1997 Jay Painter * gtk/gtkwindow.c: gtk-ajaborsk-971016-1 This small patch correct position for GTK_WIN_POS_CENTER and GTK_WIN_POS_MOUSE GtkWindow positions. Sat Nov 15 1997 Jay Painter * gdk/gdkgc.c: added function gdk_gc_set_clip_rectangle * gdk/gdk.h: header for above Sat Nov 15 1997 Jay Painter * gdk/gdkgc.c: added function gdk_gc_set_clip_rectangle * gdk/gdk.h: header for above Wed Nov 12 1997 Jay Painter * gdk/gdkpixmap.c: Patrice Fortier's patch for transparent pixmaps. * gdk/gdk.h: gdk/gdkdraw.c: Patrice Fortier's patch to add pixel draw function. Sun Nov 9 1997 Jay Painter * Fixed problems with makefiles relating to the bug which required glib to be installed. * Fixed makefiles to incluce the xpm's in gtk+/gtk needed for testgtk. * Updated gtk+ and gtk+/glib to libtool-1.0f Fri Nov 7 1997 Jay Painter * gtk/gtktext.c: return char_widths[ch & 0xff]; in line 2152 Thr Nov 5 1997 Jay Painter * gtk/testgtk.c: added drag and drop test, removed the test hack from the button test Tue Nov 4 08:28:57 1997 Federico Mena * gtk/gtkmain.c (gtk_handle_idle): Patch from David Mosberger to avoid crashes when handling idle function (this manifested itself in the Umax and Microtek backends in SANE. Sun Nov 2 07:34:56 1997 Tim Janik * gtk/gtkfilesel.c: Small fixes about a segmentation viaolation cause by a double click in the directoy list (introduced by my previous changes). * gtk/gtklist.c: Small fixes to gtk_list_add() and gtk_list_remove(). * gtk/testgtk.c (list_add): Applied Stefan Wille's patch to make this function do something ;). Fri Oct 31 Jay Painter *gdk/gdk.c: reformatted DND code for GTK coding standards *gdk/gdkwindow.c: changed memory allocation for DND to q_mem stuff Thu Oct 30 Jay Painter * gdk/gdkwindow.c: * gdk/gdk/gdk.h: * gtk/gtkwidget.h: * gtk/gtkwidget.c: Applied Stephan Willie's shaped window patch * gdk/gdkwindow: * gdk/gdk.h: * gtk/gtkwidget.h: * gtk/gtkwidget.c: reformatted the DND code to conform to GTK coding standards * gtk/testgtk: massive fixes, SW's shaped window example Thu Oct 30 07:33:27 1997 Tim Janik * gtk/gtklistitem.c (gtk_real_list_item_toggle): applied Johannes Keukelaar's patch for keyboard support in GtkList widgets. * gtk/gtkfilesel.c: adapted dir and file list selection behaviour to deal with keyboard selections. this is a little bit tricky: in the dir list it just changes the entrys value on a one button press. but on a keyboard selection via gtk_widget_activate() it does a new population (likewise on a double click) as this seems more obvious. 1997-10-25 Marius Vollmer * gdk/gdkcolor.c (gdk_colormap_get_system): Initialize private->ref_count. Wed Oct 22 09:47:43 1997 Tim Janik * gtk/gtkwindow.c (gtk_window_key_release_event): Fixed a stupid bug that caused the key_release_event to be propagated twice. Sun Oct 12 11:01:43 1997 Tim Janik * acconfig.h: * configure.in: * gdk/gdkimage.c: Added configure check for IPC_RMID_DEFERRED_RELEASE, because shmat() fails after a shmctl(..., IPC_RMID,...) for OSF1 V3.2, SunOS 4.1.1, 5.5, 5.5.1, 5.6, IRIX 5.2 and 6.2. Mon Oct 6 11:59:07 1997 Federico Mena * gdk/gdk.c (gdk_event_translate): In line 1693, fixed typo that would cause motion notify events not to be delivered. Sun Oct 5 18:15:06 1997 Federico Mena * gtk/gtkrc.c (gtk_rc_parse_bg_pixmap): Changed strdup() for g_strdup(). Wed Sep 24 17:16:34 1997 Peter Mattis * configure.in: Fixed a stupid error in the test for libXext that would cause it to fail if X_EXTRA_LIBS was not empty. * gtk/gtkmain.h (gtk-timj-970919.patch): * gtk/gtkmain.c (gtk-timj-970919.patch): new function `gtk_idle_remove_by_data' to remove all idle callbacks that take a specific piece of data as argument. (gtk_get_current_event): remove idles through gtk_idle_remove_by_data. * gtk/gtkwidget.c (gtk-timj-970919.patch): (gtk_widget_destroy): remove pending idles for widgets that have GTK_REDRAW_PENDING or GTK_RESIZE_PENDING and GTK_ANCHORED set (only anchored widgets can have a resize queue handler pending). widgets that have GTK_RESIZE_NEEDED will be removed from their anchored toplevels `resize_widgets' list. (gtk_widget_queue_draw): let the widget remember the queue handler tag (through `redraw_handler_key') for later call to `gtk_idle_remove'. (gtk_widget_queue_resize): let the widget remember the queue handler tag (through `resize_handler_key') for later call to `gtk_idle_remove'. corrected referencing the toplevel widget for which the handler is pending. if a widget is added to the `resize_widgets' list of a toplevel widget, GTK_RESIZE_NEEDED is set and it's referenced. (gtk_real_widget_queue_resize): on the deletion of the `resize_widgets' list, unset GTK_RESIZE_NEEDED and unreference the removed widgets. * gtk/gtkwindow.c (gtk-timj-970919.patch): (gtk_real_window_move_resize): move `resize_containers = NULL' initialization out of if-statement. while stepping through the `resize_widgets' list, unreference the widgets and clear GTK_RESIZE_NEEDED. if a widget realy needs are resize, they are flagged through GTK_RESIZE_NEEDED now (instead of GTK_RESIZE_PENDING, as this is indicative for a pending handler). added checks to provide segfaulting if a widgets parent pointer is NULL (e.g. on toplevel widgets that have GTK_RESIZE_NEEDED set). Tue Sep 23 13:23:27 1997 Federico Mena * gdk/gdkimage.c: Applied Tim Janik's patch to mark shm segments as IPC_RMID so that they are automatically removed always. * gdk/gdkfont.c: Removed casts from lvalues. * gtk/gtkmain.c: Removed GTK_RETLOC_*() (which do a cast) from lvalues. * gtk/gtkaccelerator.c (gtk_accelerator_table_remove): Added "const" to the accelerator_key param to be consistent with the declaration in gtkaccelerator.h. The const is not useful in this case, anyway. Tue Sep 16 13:11:06 1997 Peter Mattis * gtkpreview.c: Andrew Logan Kieschnick's change to eliminate round-off error when gamma is set to 1.0. * gtkrange.c: * gtkviewport.c: Jay Painter's changes to modify the way in which viewports resize. * gdkinput.c: * gdkinputgxi.h: * gdkinputxfree.h: * gtk/Makefile.am: * gtk.h: * gtkeventbox.c: * gtkeventbox.h: Owen Taylor's event box widget and fixes for X input support (that I had broken). * gdk.h: * gdkwindow.c: * gtksignal.h: * gtksignal.c: Elliot Lee's changes to support Objective C. (id is apparently a reserved word in Objective C). Sun Sep 14 22:33:15 1997 Peter Mattis * gtkwidget.c (gtk_widget_queue_resize): If the toplevel container is invisible we simply call "gtk_container_need_resize" on it. This fixes a bug with option menus not redrawing correctly. * gtkmenuitem.c (gtk_menu_item_enter): (gtk_menu_item_leave): These functions now simply pass the event on to their parent. This is necessary for menus to work properly due to the change in how grabs are dealts with. * gtkwindow.c (gtk_real_window_move_resize): Fixed a bug that caused the GTK_RESIZE_PENDING flag to not be unset in some cases. Fri Sep 5 20:49:37 1997 Marius Vollmer Bug fixes: * Makefile.am: Added PATCHES to EXTRA_DIST. * gtk/gtkpixmap.c (gtk_pixmap_new): Move the "pixmap != NULL" test after the allocation of the pixmap. To shut up the compiler: * gtk/gtkfilesel.c (get_pwdb): Initialize home_dir. * gtk/gtkmain.c (gtk_init): Replace comments around calls to g_set_*_handler with "if (0)". * gtk/gtkrc.c (gtk_rc_get_token): Initialize hex_number and float_number. * gtk/gtkwindow.c (gtk_window_key_press_event): Initialize direction. Changes to the type system in gtk/: * Makefile.am: Added gtktypebuiltins.h to gtkinclude_HEADERS. Added gtk.defs, runelisp, gentypeinfo.el and gtktypebuiltins.c to EXTRA_DIST. Added rules to generate gtktypebuiltins.* from gtk.defs. * runelisp, gentypeinfo.el, gtk.defs: New files. * gtkaccelerator.c, gtkaccelerator.h (gtk_accelerator_table_ref): Return the table so that this function can be used as the `copy' function for GTK_TYPE_BOXED values. * gtkstyle.c, gtkstyle.h (gtk_style_ref): Likewise. * gtkenums.h: Removed GtkArgType enum. * gtkmain.c (gtk_init): Call gtk_type_init to initialize the type system. * gtkobject.c (gtk_object_init_type): New function to take over for gtk_object_get_type. (gtk_object_get_type): Just return the constant GTK_TYPE_OBJECT. (gtk_object_collect_args): Do the right thing for the new GTK_TYPE_* types. * gtksignal.c (gtk_params_get): Likewise. * gtktypeutils.c: (gtk_type_init_builtin_types): New function. (gtk_type_init): Call it. Also made non-static. (gtk_type_unique): The allocation scheme for numerical ids has changed: The low 8 bits hold the appropriate GtkFundamentalType of a type, the rest is a globally unique sequence number. (gtk_type_hash): Use the sequence number of a key to hash it. (gtk_type_register_builtin): New function. * gtktypeutils.h: (GtkFundamentalType): New enumeration of the fundamental types. (GTK_TYPE_MAKE, GTK_FUNDAMENTAL_TYPE, GTK_TYPE_SEQNO): New macros to work with the new id scheme. (GtkArg): Added fields for new types and renamed old ones. GtkArg should now be a mostly opaque structure, except name and type. (GTK_VALUE_*): New macros to access the values of a GtkArg. (GTK_RETLOC_*): New macros to access the location of a return value that is contained in a GtkArg. * gtktypebuiltins.h: New file to access the typeids of the builtin types. * gtkwidget.h (GTK_TYPE_WIDGET): New macro to access the type id of the widget class. Thru out: Changed GTK_ARG_* to the appropriate GTK_TYPE_*. Changed access to GtkArg structure to the appropriate GTK_VALUE_* or GTK_RETLOC_* macro. Changed GtkArgType to GtkType. Changed some guints to GtkType. General changes in gtk/ to support interpreters: * gtkradiobutton.c (gtk_radio_button_new_from_widget, gtk_radio_button_new_with_label_from_widget): New functions. * gtksignal.c (gtk_signal_connect_no_marshal): New function. (struct _GtkHandler): Added no_marshal and destroy_func fields. (gtk_signal_handler_new): Initialize them. (gtk_signal_connect_by_type): Added no_marshal and destroy_func arguments. Changed all callers. (gtk_signal_destroy): Invoke destroy_func if there is one and the global destroy func does not apply. (gtk_handlers_run): If the handler has no_marshal set, call its function directly without going thru the signal's marshaller. Wed Sep 3 09:56:22 1997 RHS Linux User * gtkrange.c: Changed the way the range control focus was drawn so that the range control is drawn correctly when it does not have the focus. Tue Sep 2 17:41:17 1997 RHS Linux User * gtkwidget.c: 'gtk_real_widget_queue_resize' should only remove the "resize_widgets" if another resize is not pending. Mon Sep 1 18:28:08 1997 Peter Mattis * gtkmain.c: Changed the way GDK_DELETE events are handled. Only, if 'gtk_widget_event' returns TRUE is the widget destroyed. By default, 'gtk_widget_event' will return FALSE causing the window to not be destroyed. This prevents segfaults in the GIMP and other programs that do not correctly handle GDK_DELETE events. * gtkmain.c: Added modal dialog support by allowing events destined for a child of the grab widget to go to the child instead of the grab widget. (Added 'gtk_widget_is_ancestor' to determine the relationship between the grab widget and the event widget). * *.[ch]: Incorprated a whole mess of patches. (Started keeping the ChangeLog up to date again). Thu Jun 5 17:22:21 1997 Peter Mattis * gtkmenufactory.c: * gtkmenufactory.h: Added 'gtk_menu_factory_remove_*' calls. Removing entries/paths causes the associated widgets to be destroyed. * gtkwidget.c: * gtkwidget.h: Calling 'gtk_widget_set_style' is used as an indication that the programmer specifically wants that style to be used. RC-style substitution is disabled for the widget after such a call. * gtkpixmap.c: * gtkpixmap.h: * gtkimage.c: * gtkimage.h: Changed to use clip mask and a single pixmap (or image) to deal with transparent areas. * gdkpixmap.c: Modified xpm loading routines to optionally return a clip mask. * gdkgc.c: * gdkdraw.c: * gdktypes.h: Modifications to allow clip masks to be used with gc's. Clip masks are bitmaps that specify drawable regions. Thu May 1 03:11:51 1997 Peter Mattis * gtkscrolledwindow.c: Scrolled windows need to have the GTK_NO_WINDOW flag set. Not having it set caused an obscure redrawing bug. Wed Apr 30 12:38:03 1997 Peter Mattis * gtkhruler.c: * gtkvruler.c: Fixed a small bug that caused the indicator to be positioned slightly off. Sun Apr 27 14:28:21 1997 Peter Mattis * gtkmenushell.c: * gtkmenushell.h: * gtkmenu.c: * gtkmenu.h: Changes so that if a menu is popped up there is a timeout period during which a menu item will not be activated and if the mouse button is released in that period the menu will stay popped up. * gtkcurve.c: * gtkcurve.h: Included curve widget courtesy of David Mosberger-Tang (davidm@azstarnet.com). * gtkentry.c: * gtkentry.h: Changed "insert" and "delete" signals to "insert_text" and "delete_text" respectively. (The symbol "delete" cannot be used since it is a C++ reserved word). Sat Apr 19 01:43:49 1997 Peter Mattis * gtkmenufactory.c: A path which ends in "" will cause an invisible (hidden) menu entry to be created. This is useful for setting an accelerator key for which a corresponding menu entry is not desired. * gtktooltips.c: Fixed some problems with destruction of the active tip widget not properly updating the tooltips data structures. Fri Apr 18 15:09:45 1997 Peter Mattis * gtkcontainer.c: * gtklist.c: * gtkwidget.c: * gtkwidget.h: Patch from Owen Taylor (owt1@cornell.edu) which fixes problems with destruction of objects and with destruction of objects which hold the focus. Thu Apr 17 11:29:15 1997 Peter Mattis * gtkmenushell.c: Incorrect logic in 'gtk_menu_shell_button_release' for deciding when a menu should stay popped up when the mouse button is released. * *.c: Miscellaneous fixes from folks on the net. Tue Apr 15 02:43:17 1997 Peter Mattis * *.c: * gtkwidget.h: Added GTK_BASIC widget flag which when set specifies a widget as "basic". A "basic" widget is one which doesn't take input events. For example, labels, pixmaps, boxes, tables, alignments, etc. Sat Apr 12 15:23:08 1997 Peter Mattis * gtkcolorsel.c: Add "#include " to define M_PI. * gtksignal.c: Fixed a bug in 'gtk_signal_emit' which showed up because of the new cast checking macros. The 'object' was being accessed after it had been destroyed. * gtkoptionmenu.c: Fixed bug with using 'GTK_BIN' instead of 'GTK_BUTTON' which showed up because of the new cast checking macros. * *.h: 'GTK_CHECK_CAST', 'GTK_CHECK_CLASS_CAST' and 'GTK_CHECK_TYPE' used by standard widget macros everywhere. Wed Apr 9 00:54:17 1997 Peter Mattis * docs/gtk.texi: Started further work on documentation. Major changes and additions are being made. * gtkarrow.c: * gtkarrow.h: Removed function 'gtk_arrow_get'. * gtkcontainer.c: 'gtk_container_check_resize' no performs additional checking to account for the case where the containers allocation is no longer sufficient because its parent (or its parents parent, etc.) needs to resize its children. Tue Apr 8 21:15:50 1997 Peter Mattis * gtkstyle.c: Fixed a bug in 'gtk_style_init' in which the font was not ref'd (via 'gdk_font_ref'), but was free'd (via in 'gdk_font_free') in 'gtk_style_destroy'. (David Mosberger-Tang). Also cleaned up 'gtk_style_destroy' while I was at it. * gtkmain.c: Fixed a bug in 'gtk_propogate_event' which caused entry widgets (and probably other widgets) not to be destroyed in some instances. Mon Apr 7 01:20:38 1997 Peter Mattis * gtkentry.c: * gtkentry.h: Changed the "insert_text", "delete_text" and "changed_text" signals to "insert", "delete", and "changed" respectively. They really should have been named this way originally except the previous signal mechanism prevented duplicate signal names. ("changed" is also used by adjustments). * gtkradiomenuitem.c: * gtkradiomenuitem.h: New widget. * gtkcheckmenuitem.c: * gtkcheckmenuitem.h: New widget. * gtksignal.c: Modified 'gtk_signal_lookup' to require an object type to be passed as a parameter. In addition, signals are now only needed to be uniquely defined in their branch of the class hierarchy. This allows the same signal name to be used in two different branches of the class hierarchy. For instance, the "changed" signal is used both by adjustments and entries...in different ways! * gtktypeutils.c: Added 'gtk_type_parent' which returns the parent type for a given type. Sun Apr 6 22:08:35 1997 Peter Mattis * gtkwidget.c: If a widget is set insensitive it loses the focus if it had it. * gtkcontainer.c: Insensitive widgets no longer participate in tab traversal. * gtkscrolledwindow.c: The "viewport" child is now destroyed and a container class "foreach" function was written (which fixes the sensitivity bug). Sat Apr 5 14:25:38 1997 Peter Mattis * gtkhscrollbar.c: * gtkvscrollbar.c: Fixed trough size allocation bug. * gtkhscale.c: * gtkvscale.c: Fixed trough size allocation and position bug that showed up when scales were placed in notebooks. Thu Mar 27 17:45:54 1997 David Mosberger-Tang * gtk/gtkmain.c (gtk_handle_idle): Fix appending pending_idles to idle_functions so it works even when idle_functions is empty. Sat Mar 15 14:15:59 1997 Peter Mattis * *.[ch]: Moved '*_class_init' and '*_init' function declarations for widgets into the source file as those functions no longer had to be public. * gtkcheckbutton.c: Fixed redrawing of check button. * gtkframe.c: Fixed redrawing of frame when the shadow type is changed. Sat Mar 8 15:19:23 1997 Peter Mattis * gdkimage.c: Fixed a stupid bug with 'gdk_image_new' which potentially added a NULL image to "image_list" and caused problems when 'gdk_image_exit' was called. Wed Mar 5 00:40:08 1997 Peter Mattis * gtkpreview.c: Massively changed the colormap handling used by the preview widget. Gray previews are now dithered. A single visual and colormap is shared by the color and gray previews. A GTK_PREVIEW_INFO property is installed on the root window in certain cases to allow multiple GTK programs to share the system colormap. Sun Mar 2 05:43:06 1997 Peter Mattis * gtkcheckbutton.c: 'gtk_checkbutton_size_allocate' was allocating too much space to its children and not leaving the check button room for the focus border. * gtknotebook.c: 'gtk_notebook_size_request' wasn't requesting enough space when the notebook tabs are visible. Sat Mar 1 01:59:35 1997 Peter Mattis * gtkpreview.c: Fixed a problem with 'gtk_preview_put' when the image byte order is GDK_MSB_FIRST. * gtksignal.c: * gtksignal.h: Added 'gtk_signal_connect_after' and 'gtk_signal_connect_object_after' functions. These connect signal handlers which will run after the class function associated with the signal. * gtkstyle.c: Fixed a stupid bug in 'gtk_style_new_from_key' that was causing twice as many styles to be created as necesary. * gtkwidget.c: 'gtk_real_widget_size_allocate' erases the widgets old allocation if it has the GTK_NO_WINDOW flag set. * gtkwidget.c: 'gtk_real_widget_unmap' now erases the widget if it has the GTK_NO_WINDOW flag set. * gtklabel.c: Removed 'gtk_label_unmap' as similar functionality was added to gtk_real_widget_unmap. * gtkbin.c: Modified 'gtk_bin_map' and 'gtk_bin_unmap' so that it erases and draws the widget if it has the GTK_NO_WINDOW flag set. * gtkframe.c: Modified 'gtk_frame_size_allocate' so that it erases the old allocation. Fri Feb 28 03:27:05 1997 Peter Mattis * gtkwindow.c: 'gtk_window_set_title' now changes the window title if the window is already realized. * gtkentry.c: 'gtk_entry_set_text' was emitting both a "delete_text" and a "changed_text" signal. Modified so that it only emits a "changed_text" signal. * gtkpreview.c: Modified to work correctly on systems with MSB byte order. The colormap for TRUE and DIRECT color displays is now created if the default visual is not equal to the visual we are using. * gtkstyle.c: 'gtk_style_attach' and 'gtk_style_find' weren't working properly in the presence of multiple colormaps are different depth visuals. * gtkcontainer.c: Massively improved focus traversal using tab and arrow keys. It now uses the layout of the widgets to determine where to move the focus to. Mon Feb 24 03:24:02 1997 Peter Mattis * gtkmenufactory.c: Set the accelerator table field for menus when they are created. * gtkmenu.c: * gtkmenu.h: Added a default accelerator table field to menus so that runtime modification of accelerator keys in menus can work better. * gtkrange.c: 'gtk_range_default_{h,v}motion' had faulty logic for deciding what to do when the slider was at the edge of the trough. They previously didn't update the adjustment value event if the value wasn't what it should be when the slider was at the edge of the trough. * gtkviewport.c: 'gtk_viewport_size_allocate' and 'gtk_viewport_adjustment_value_changed' both had the potential for performing a divide by 0. Checks are now in place to prevent this. * gtkmenu.c: 'gtk_menu_map' now makes sure the menu lies on screen if the position function is NULL. * gtkentry.c: Modified selection handling. 'gtk_delete_selection' actually removes the X selection now. 'gtk_entry_destroy' removes the selection as well and relies on the change in "gdk.c" to make sure the selection event will not be sent to a non-existant window. * gdk.c: Selection events are only passed on if the selection owner is not NULL. * gtkstyle.c: 'gtk_style_detach' and 'gtk_style_destroy' were not destroying the black and white gc's. Sun Feb 23 19:17:56 1997 Peter Mattis * gtkwindow.c: 'gtk_window_size_request' was setting the window hints. This was also being done in 'gtk_window_map', so the instance being done in 'gtk_window_size_request' was removed. Fri Feb 21 01:04:01 1997 Peter Mattis * gtkwidget.c: 'gtk_widget_draw' has to use the widgets allocated position for the drawing rectangle when the widget has the GTK_NO_WINDOW flag set. * gtkwidget.c: In 'gtk_widget_init' the visual and colormap were being directly compared against 'default_visual' and 'default_colormap' instead of calling 'gtk_widget_get_default_{visual,colormap}'. * gdkrectangle.c: Amazing! There was a bug in the 'gtk_rectangle_intersect' logic. Its been there for near eternity and I never noticed. * gtkpreview.c: * gtkpreview.h: Created preview widget which allows drawing to an rgb or grayscale buffer which is automatically displayed on the screen. Performs dithering as necessary. Thu Feb 20 20:33:21 1997 Peter Mattis * gdkwindow.c: Modified the logic in 'gdk_window_new' which determined when to add a window to the WM_COLORMAP_WINDOWS property. Wed Feb 19 19:55:29 1997 Peter Mattis * gtkruler.c: 'gtk_ruler_make_pixmap' was always destroying the old backing store and creating a new one even when it would create a new one of exactly the same size as the old one. Tue Feb 18 18:32:10 1997 Peter Mattis * gmem.c: 'g_mem_chunk_alloc' was incorrectly modifying the mem areas free mem field when reallocating a previously freed atom. This caused a fairly severe memory leak. * gtkmenushell.c: 'gtk_menu_shell_button_release' had a bug in the logic for deciding whether to initiate an X pointer grab or not when the mouse button was released. It now only initiates a grab if the mouse is released within an active menu item. Fri Feb 14 00:57:40 1997 Peter Mattis * gtknotebook.c: Changed the look of notebook tabs slightly. * gtkentry.c: * gtkentry.h: Deleting an entry widget which is holding the X selection presents some difficulties. The X selection must be released, but the widget can't be destroyed until the SELECTION_CLEAR event is received that the X server will send in response to clearing the X selection. There are probably still bugs in the current method of entry widget deletion when the X selection is held. * gtkmain.c: 'gtk_propagate_event' was not properly destroying the toplevel window when receiving a key press event. * gtkwidget.c: Setting a widget insensitive did not cause it to redraw. It now does. Thu Feb 13 16:59:07 1997 Peter Mattis * gtkviewport.c: 'gtk_viewport_size_allocate' was allocating its child widget an adjusted allocation. Since the actual scrolling has handled by a subwindow this caused the child to be double scrolled. Modified to always set the child allocations origin to (0, 0). Wed Feb 12 01:06:48 1997 Peter Mattis * gtkentry.c: Text is now centered vertically. Previously it was pushed up against the top. This problem was only evident when the widget was allocated more vertical space than it requested. * gtkfilesel.c: 'gtk_file_selection_key_press' was previously only a stub for tab completion. The actual tab completion call had been left out. (Oops!) Tue Feb 11 01:43:08 1997 Peter Mattis * gtksignal.c: 'gtk_signal_disconnect_by_data' was going into a loop and crashing. Bad logic. Fixed. * gtkmain.c: An idle function which returns FALSE will be removed from the list of idle functions. This makes the functioning of idle functions and timeouts more similar. * gtkentry.c: 'gtk_entry_get_text' now returns an empty string when the actual text is NULL. This allows "stupid" programs to use the value returned by 'gtk_entry_get_text' blindly (without checking to see if its NULL). * gtkradiobutton.c: Modified 'gtk_radio_button_clicked' so that 'gtk_toggle_button_toggled' is called _after_ the widget state is changed. * gtksignal.c: * gtksignal.h: Added 'gtk_signal_name' which returns the character string name for a given signal number. * gtkwidget.c: 'gtk_widget_set_parent' checks to see if the widget is now "anchored" through the parent chain to a widget which is GTK_ANCHORED. If it is, then it changes the widgets style using 'gtk_rc_get_style' and recursively performs the same operation on the widgets children. This is necessary is 'gtk_rc_get_style' only works properly on "anchored" widgets. * gtkwindow.c: Modified GTK_WIN_POS logic so that it is only used immediately after the window has been shown. * gtkmenu.c: 'gtk_menu_key_press'. Can now change menu item accelerator keys on the fly. Why? Why not. Cool/useless feature of the day. * gtkmenuitem.c: Accelerator key drawing. Somehow that never got finished. (Oops!) * gtkdrawingarea.c: 'gtk_drawing_area_size_allocate' was not actually installed during 'gtk_drawing_area_class_init'. (Oops!) * gtkframe.c: 'gtk_frame_size_request' fixed size requisition problem caused by unsigned arithmetic. * gtkwindow.c: Modified window widget so that it only uses the widget uposition auxiliary information immediately after it has been shown. This prevents the annoying bug which can cause a uposition'ed window to jump back to its original position after the user moves it. * gtkwidget.c: Need to ref and unref style in 'gtk_widget_{push,pop}_style' to make sure that a style on the style stack is not destroyed. * gtktogglebutton.c: 'gtk_toggle_button_set_state' now calls gtk_button_clicked to actually change the state of the button. In this way, radio buttons can now perform the appropriate actions when the toggle button state is set. Mon Feb 10 00:27:39 1997 Peter Mattis * gtklist.c: 'gtk_list_select_item' and 'gtk_list_unselect_item' were casting a GList* variable to a a GtkWidget* variable. Bad bad bad. (Tim Janik). * gtksignal.c: Modified 'gtk_signal_connect' and 'gtk_signal_connect_object' to warn when a signal type cannot be found. Sun Feb 9 00:15:30 1997 Peter Mattis * gtkoptionmenu.c: * gtkoptionmenu.h: Changed option menus back to being derived from buttons. This fixes up some screwiness with their user interaction. * gtkwindow.c: Modified key press handler to support focus traversal. * gtkcontainer.c: * gtkcontainer.h: Added default focus traversal back in. Sat Feb 8 10:44:38 1997 Peter Mattis * gtkviewport.h: * gtkviewport.c: Massively sped up viewport scrolling. Used to be reallocating child's size (offset) each time a scrollbar moved. Now a subwindow is moved. All the children are moved automatically by moving the subwindow. Much much much faster. Tue Feb 4 00:20:44 1997 Peter Mattis * gtree.c: Changed 'g_tree_node_search' to use a loop instead of recursion. Mon Feb 3 11:30:03 1997 Peter Mattis * gtkbutton.c: Removed 'parent_destroy' global and replaced it with 'parent_class' global to reflect style used in other widgets. * gtknotebook.c: Tab labels were being allocated less than their requested size. * gtkrange.c: * gtkrange.h: Moved the "digits" field of scales into the range type. The adjustment value for scales is truncated to the number of visible digits instead of being left untouched. * gtree.c: Fixed a bug in the AVL tree implementation. Single rotations were always being performed during insertion. It is sometimes necessary to perform a double rotation. * gtklabel.c: Modified 'gtk_label_expose' to only draw the label when the allocated space is greater than or equal to the requested space. * gtklabel.c: Added call to 'gtk_widget_unmap' to 'gtk_label_destroy' in order for the label to redraw correctly (erase itself) when destroyed. * gtklabel.c: Added 'gtk_label_unmap' call which erases the labels allocation when it gets unmapped. * *.h: Removed a few remaining instances of using "class" as a parameter name. (Causes problems for C++). Fri Jan 31 12:26:50 1997 Peter Mattis * gtkcontainer.c: 'gtk_container_enable_resize' needs to call 'gtk_container_check_resize' instead of 'gtk_container_need_resize'. * gtkwidget.c: 'gtk_real_widget_show' now maps the widget if its parent is mapped. * gtkscrolledwindow.c: Fixed size allocation when the scrollbar policy's are GTK_POLICY_AUTOMATIC. Doing it correctly is harder than I originally thought. * gtklist.c: Added 'gtk_list_child_position' to determine the integer position in a list of a child. Filled in the 'gtk_list_item_select' and 'gtk_list_item_unselect' stubs. Thu Jan 30 16:08:06 1997 Peter Mattis * gmem.c: Changed the implementation of G_ALLOC_AND_FREE mem chunks. They used to allocate SIZEOF_VOID_P extra bytes per atom in order to keep track of which mem area they were allocated from. Now the mem area is determined by searching through an AVL tree of the mem areas for a mem chunk and comparing memory locations. A little slower, but makes G_ALLOC_AND_FREE mem chunks much more attractive. * gtree.c: Added an AVL tree implementation to glib. * gtksignal.c: * gstring.c: va_arg (arg_list, {char, short}) is invalid. Arguments passed in a variable argument list are promoted. ({char, short}->int). Seemed to work ok before under Linux. Crashed under FreeBSD. Tue Jan 28 02:27:51 1997 Peter Mattis * gdkwindow.c: Fixed a major slowdown apparent in the file selection dialog which was caused by calling 'gtk_window_add_colormap_windows' way way way too often. * *.c: Many widgets called 'gtk_container_need_resize' when something internal changed which would cause the widget to grow or shrink. The assumption was made that the widget would change size and an expose event would be generated. This happens "most" of the time. But its possible for certain widgets to change size without generating expose events, or for its internal geometry to change without a change of size which would mean no expose event was generated. So a wrapper function called 'gtk_container_check_resize' was created and 'gtk_container_need_resize' was modified so that it returns FALSE if a resize was actually generated and TRUE if nothing changed. This allows 'gtk_container_check_resize' to initiate a 'gtk_widget_size_allocate' and 'gtk_widget_draw' to emulate the expose event. Sat Jan 25 14:17:44 1997 Peter Mattis * gtkmain.c: Fixed a bug with propogating key press events. The events were sent 2 times to the toplevel windows which caused the focus widget to be activated twice when the space bar was pressed. * */configure.in: * */Makefile.am: Added support for libtool and removed the old shared library configuration craziness. Fri Jan 24 12:59:22 1997 Peter Mattis * gtktext.c: * gtktext.h: Josh's fixes and additions to the text widget. * gtkfill.c: * gtkfill.h: Filler widget useful for filling space in a table. Can specify a minimum size. Used by the canvas widget. * gtknotebook.c: * gtknotebook.h: Made outline of notebook widget. * gtkcanvas.c: * gtkcanvas.h: Started canvas widget. A composite of 2 rulers (w/ an origin), 2 scrolllbars. Guides, grids, snap to. Sun Jan 19 18:26:45 1997 Peter Mattis * gtkdialog.c: * gtkdialog.h: Created dialog widget which creates a standard looking dialog with buttons along the button and a separator. * gtkxid.c: Generalized the window table code for looking up a gdk window based on an XID to work for any XID and a piece of data. Can now look up gdk fonts based on their XID. * gtkruler.c: * gtkruler.h: * gtkhruler.c: * gtkhruler.h: * gtkvruler.c: * gtkvruler.h: Started conversion of the ruler widget. * gtktext.c: * gtktext.h: Started conversion of the text widget. Scrolling doesn't work. * gtkmain.c: Fixed a fairly major bug. The event widget needs to be in a call for the entire duration of handling an event. Not just for when the event widget itself is handling the event. * gtkfilesel.c: Fixed up some bugs with resizing. Fri Jan 10 14:18:03 1997 Peter Mattis * gtkwidget.c: * gtkwidget.h: * gtkentry.c: * gtkentry.h: Support for selections. * gdkselection.c: * gdk.c: * gdktypes.h: * gdk.h: Gdk support for X selections. Currently only text selections are supported. * gtksignal.c: Fixed a major bug which occurred when destroying an object. Memory was being written to after it was freed. * gtkfilesel.c: * gtkfilesel.h: Hooked up more functionality to the file selection dialog. Wed Jan 8 18:13:53 1997 Peter Mattis * gtkfilesel.c: * gtkfilesel.h: Mostly converted old file selection dialog widget. The widget is derived from the GtkWindow class and is quite a bit simpler in the widget code. * gtkwidget.c: Fixed 'gtk_widget_grab_focus' and 'gtk_widget_grab_default' to check that the toplevel widget is a type of window (which includes classes derived from windows). Tue Jan 7 01:12:32 1997 Peter Mattis * gtkwindow.c: Was calling 'gtk_window_resize' twice in a row...why? * gtksignal.c: * gtksignal.h: * *.c: Changed 'gtk_signal_new' so that the class function that is called when the signal is emitted can be called either before, after or both before and after the calling of any signal handlers. * gtkobject.c: * gtkobject.h: Added 'object_data' mechanism for storing data associated with a character string key in objects. Removed 'user_data' field of objects and changed 'gtk_object_{get,set}_user_data' to use the object data mechanism. Removed 'handlers' field of objects. * gtkwidget.c: * gtkwidget.h: * gtkwindow.c: Modified aux info mechanism to use object data mechanism. * gtksignal.c: Modified signal mechanism to use object data mechanism instead of 'handlers' field. Mon Jan 6 15:10:16 1997 Peter Mattis * gtkmenushell.c: Fixed up button press handling so as to conform more closely to that used by Motif. Wed Jan 1 21:27:17 1997 Peter Mattis * gtkmenu.c: * gtkmenu.h: * gtkmenubar.c: * gtkmenubar.h: * gtkmenushell.c: * gtkmenushell.h: Reorganization of menu-ing code so that code duplication is reduced. The menu shell now contains most of the code for menu-ing interaction while menus and menubars simply layout their child menu items in the appropriate place. Sun Dec 29 17:48:18 1996 Peter Mattis * gtkmenu.c: * gtkmenubar.c: * gtkmenuitem.h: * gtkmenuitem.c: Modifications so that menu item accelerators and the submenu indicator are drawn correctly and the correct amount of space is allocated. Sat Dec 28 00:32:13 1996 Peter Mattis * gtkmenufactory.h: * gtkmenufactory.c: Started menu factories as an easy method to create and manipulate menus. Fri Dec 27 13:17:34 1996 Peter Mattis * gtkmenu.c: * gtkmenu.h: * gtkmenubar.c: * gtkmenubar.h: * gtkmenuitem.c: * gtkmenuitem.h: * gtkmenushell.c: * gtkmenushell.h: Implemented basic menu functionality. Menubars and popup menus work. Submenus work. (Much left to be done). Wed Dec 18 15:27:05 1996 Peter Mattis * gtktypeutils.h: * gtktypeutils.c: Added 'gtk_type_from_name' which returns a type identifier given a type name. Implemented using a second hash table keyed by type names. * gtkbutton.c: * gtktogglebutton.c: Fixed very small messed-up drawing bug when a button loses its focus. * gtkwidget.h: * gtkwidget.c: * gtkbutton.c: * gtkwindow.c: Added default button handling. Default buttons now draw correctly and pressing return or enter causes the default button (if one exists) to be activated. Tue Dec 17 19:32:21 1996 Peter Mattis * gtkhscale.c: * gtkvscale.c: Overrode 'draw_slider' method of ranges in order to draw the slider of scales with a line in them so as to be closer to the Motif look-and-feel. * gtkwindow.c: Modified 'gtk_window_focus_in_event' so that focus in events are only handled when the window is visible. Fixes a bug where spurious focus in events get sent when a window is being hidden. * gtkwidget.h: Added 'activate_signal' field to the GtkWidgetClass structure. Added 'gtk_widget_activate' call to emit the activate signal for a widget if it is non-zero. Tue Dec 10 15:59:45 1996 Peter Mattis * gtkwidget.c: 'gtk_widget_set_name' oops in strdup'ing the old "widget->name" instead of the new one we are setting. * gtkrc.c: 'gtk_rc_widget_path' changed to use 'gtk_widget_get_name' instead of accessing the "widget->name" field directly. * gtkwidget.c: Added 'gtk_widget_get_name' function which returns the widgets name if it exists and the widgets type name if it does not. * gtkcheckbutton.c: Added 'gtk_check_button_draw' function. Modified 'gtk_check_button_expose' to pass an expose event to child instead of callings its draw function. * gtkentry.c: 'gtk_entry_draw_text' why was "+1" being added to the font->ascent to calculate the font position? This was wrong and caused some characters in fonts to be clipped. (Notably "g"). * gtkentry.c: 'gtk_entry_realize' specify GTK_BUTTON1_MOTION_MASK and GTK_POINTER_MOTION_HINT_MASK for _both_ windows. * gtkmain.c: 'gtk_propagate_event' needs to set the GTK_IN_CALL flag for the object before calling 'gtk_widget_event' and needs to destroy the object if necessary after 'gtk_widget_event' returns. * gtkradiobutton.c: 'gtk_radio_button_clicked' needs to call 'gtk_toggle_button_toggled' when the currently active button is toggled. * gtkwidget.c: 'gtk_real_widget_hide' needs to call 'gtk_widget_unmap' if the widget is currently mapped. * gtkwindow.c: Prevent automatic resizing after the user has specified a new window size. Add 'handling_resize' flag to windows. * gtkscrolledwindow.c: Implement the GTK_POLICY_AUTOMATIC scrollbar policy. Need to connect to the adjustments 'changed' signal and notice when the scrollbars aren't in use. * gtkcontainer.c: 'gtk_container_init' must set 'auto_resize' and 'need_resize' fields to TRUE and FALSE respectively. * gtkwidget.c: 'gtk_widget_set_parent' must all set a widgets state to its parents state. Sun Dec 1 01:31:01 1996 Peter Mattis * Started ChangeLog
