ok, there have been several severe bugs in the signal handler referencing Tue Feb 10 07:12:07 1998 Tim Janik <timj@gimp.org> * gtk/gtksignal.h: * gtk/gtksignal.c: ok, there have been several severe bugs in the signal handler referencing and ->next connection stuff. these bugs caused invokations of handlers that are disconnected and - worse - destroyed already. invokation of *destroyd* handlers mean: anything can be executed , because the handler structure can just as well be realocated. at the cost of an extra ->prev field per handler we should have a reasonable stable system now, because of the various places that can cause a handler to be disconnected (*any* handler invokation can cause *any* or *all* handlers to be disconnected, there is no way around a doubly linked list, actually handler disconnection has never worked correctly because of this. handlers are connected together via a *doubly* linked list now, and it is *not* valid to remove a handler out of this list untill all its references have been droped, i.e. handler->ref_count==0. to prevent emissions of disconnected but still referenced handlers, disconnected handlers are simply marked as blocked and get an id of 0 which is an invalid signal handler id. the handler->id has been changed to have 28 significant bits (using alignment gaps), since 65536 (old range: guint16) signal connections (as a total) can easily be reached by complex applications. this whole handler thingy is at least as tedious as writing doubly linked list implementations ;)

* - The timeout is executed

Remove --g-fatal-warnings flag from argv. Thu Jun 18 21:13:54 1998 Owen Taylor <otaylor@gtk.org> * gtk/gtkmain.c (gtk_init): Remove --g-fatal-warnings flag from argv. Thu Jun 18 20:22:28 1998 Owen Taylor <otaylor@gtk.org> * gtk/genmarshal.pl: Modified to be more idiomatic Perl, to be more readable perl, to spit out stuff that looks more like readable C, and to pipe output through indent so output looks a lot like readable C. No functional changes. Thu Jun 18 17:43:31 1998 Owen Taylor <otaylor@gtk.org> * gtk/gtkpixmap.[ch] (gtk_pixmap_set): Clear the background if necessary when switching to a masked pixmap. (Based on a patch from Ullrich Hafner <hafner@informatik.uni-wuerzburg.de>) Thu Jun 18 16:18:10 1998 Owen Taylor <otaylor@gtk.org> * gtk/gtkeditable.[ch]: Added action signals for keyboard bindings. (move_cursor, kill_word, etc, etc, etc). removed the time argument from gtk_editable_cut/copy/paste_clipboard (source but not binary incompatible...) Instead get time from gtk_get_current_event (). * gtk/gtktext.c gtk/gtkentry.c: Support the new editable signals. Thu Jun 18 02:52:09 1998 Owen Taylor <otaylor@gtk.org> Patches from Damon Chaplin <DAChaplin@email.msn.com>: gtk/gtkfontsel.h: Fixed GtkFontSelectionClass - I forgot to change parent class to GtkNotebookClass when splitting the widget in two. Also updated some comments. gtk/gtkfontsel.c: Fixed bug when toggling 'Allow scaled bitmaps' button without a font selected. Fixed bug in set_font_name - I hadn't updated the code to search for the style in the font_style clist - it was still assuming the style row was equal to its index, but it isn't any more. Changed 'Reset' button on filter page to 'Clear Filter'. Deleted old code relating to the old 'Filter Fonts' toggle Updated some comments. Cleared 'Actual Fontname' if no font is set. gtk/testgtk.c: Fixed problem when 'OK' button is pressed - it was destroying the GtkFontSelection instead of the GtkFontSelectionDialog. Thu Jun 18 02:15:31 1998 Owen Taylor <otaylor@gtk.org> * gtk/gtkmain.c (gtk_init): Added --g-fatal-warnings flag to make all warnings fatal errors. * gtk/testthreads.c: moved <pthreads.h> include inside #ifdef USE_PTHREADS Thu Jun 18 01:37:31 1998 Owen Taylor <otaylor@gtk.org> * gtk/gtkenums.h gtk/gtkcontainer.[ch] gtk/gtkwidget.c gtk/gtkmenu.c gtk/gtkviewport.c gtk/gtkwindow.c: - Added new function gtk_container_set_resize_mode() for fine-grained control of where resize-queueing is done. - Removed GtkContainer::need_resize and GtkWindow::move_resize - Added GtkContainer::check_resize to replace need_resize. - Added function gtk_container_check_resize() to trigger queued resizes, and gtk_container_resize_children() to Figure which children need to be size-allocated. (logic moved from gtkwindow.c) - Reorganized code in gtkwindow.c - Set the resize-mode for viewports so that resizes within a viewport don't propagate out of it.

GTK_RESIZE_NEEDED is a private flag now. Mon Feb 2 04:15:08 1998 Tim Janik <timj@gimp.org> * gtk/gtkcontainer.h: * gtk/gtkcontainer.c: GTK_RESIZE_NEEDED is a private flag now. (gtk_container_register_toplevel): new function. (gtk_container_unregister_toplevel): new function. * gtk/gtkmain.c: GTK_LEAVE_PENDING is a private flag now. * gtk/gtkmenu.c: call gtk_container_register_toplevel in gtk_menu_class_init instead of this dirty gtk_widget_set_parent(,NULL) hack. new default handler gtk_menu_destroy for calling gtk_container_unregister_toplevel. removed GTK_ANCHORED, GTK_UNMAPPED. * gtk/gtkobject.h: macro cleanups, added GTK_DESTROYED flag. * gtk/gtkobject.c: only emit DESTROY signal if !GTK_OBJECT_DESTROYED (object). * gtk/gtkprivate.h: new file that will not be automatically included. it holds the private flags for GtkWidget along with it's SET/UNSET and examination macros. * gtk/gtkwidget.c: private flags: GTK_RESIZE_NEEDED, GTK_REDRAW_PENDING, GTK_RESIZE_PENDING, GTK_IN_REPARENT, GTK_USER_STYLE. GTK_ANCHORED is replaced by GTK_TOPLEVEL. added missing UNSET for GTK_IN_REPARENT. removed the gtk_widget_set_parent(, NULL) hack for toplevels. upon destroy free memory for widgets with GTK_WIDGET_HAS_SHAPE_MASK. * gtk/gtkwidget.h: split up the widget flags into a public and a private portion. added an extra field private_flags to GtkWidget without making it bigger by using an alignment gap of 16 bit. macro cleanups. * gtk/gtkwindow.c: removed GTK_ANCHORED. new function gtk_window_destroy for calling gtk_container_unregister_toplevel. removed the gtk_widget_set_parent(,NULL), call gtk_container_register_toplevel instead. remove GTK_UNMAPPED. GTK_RESIZE_NEEDED is private now. * gtk/gtksignal.c (gtk_signal_disconnect): removed a bug on removal that cut off the handler list -> living_objects == 0 with testgtk. made some warnings more descriptive. new function gtk_signal_connect_object_while_alive, which will automatically destroy the connection once one of the objects is destroyed. didn't include this before removal of the above mentioned bug. * reflected refcounting revolution in ChangeLog
