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

configure.in acheader.h gdk/gdkwindow.c Check for Shape extension both on Sun May 3 13:38:22 1998 Owen Taylor <otaylor@gtk.org> * configure.in acheader.h gdk/gdkwindow.c Check for Shape extension both on the client and server side. (And, more importantly, check for the shape extension so we may include -lXext even when compiling with --disable-xshm) Don't set override_redirect on all shaped windows. It isn't necessary. * gdk/gdkwindow.c: Set ->colormap to NULL for root and foreign windows. Use this to check if we need to get the colormap from X. Fri May 1 22:32:47 1998 Owen Taylor <otaylor@gtk.org> * gtk/gtkbutton.c (gtk_button_paint): Draw the areas between the default and the button always in GTK_STATE_NORMAL. * gtk/gtkrange.c (gtk_range_style_set): Added a style_set callback. Fri May 1 16:40:57 1998 Owen Taylor <otaylor@gtk.org> * gdk/gdkpixmap.c (gdk_pixmap_colormap_create_from_xpmp[_d]): Fix a buffer overflow on pixmaps that claim to have more than 31 characters per pixel. (gdk_pixmap_read_string): Don't wrap around strings longer than half of address space ;-) * gtk/gtk[vh]ruler.c gtk/gtkinputdialog.c: Expand some buffers that were used for printing integers. * */* (almost): Style: All int foo () { ... } changed to int foo (void) { ... } ^^^^^^^ This is why some many files changed Even where there were proper prototypes elsewhere. * gdk/gxid.c (handle_claim_device): Some extra checks. It isn't safe against being fed bad X id's, but at least it should be safe against deleting all your files.

(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
