* SECTION:gtkbutton
* @Short_description: A widget that emits a signal when clicked on
* @Title: GtkButton
*
* The #GtkButton widget is generally used to trigger a callback function that is
* called when the button is pressed. The various signals and how to use them
* are outlined below.
*
* The #GtkButton widget can hold any valid child widget. That is, it can hold
* almost any other standard #GtkWidget. The most commonly used child is the
* #GtkLabel.

GTK maintains a stack of GtkIconFactory to search, and applications or libraries can add additional icon factories on top of the stack * gtk/gtkrc.h, gtk/gtkrc.c: When loading an RcStyle, parse the set of GtkIconSource specified for a given stock ID into a GtkIconSet, and put the GtkIconSet into a GtkIconFactory for the RcStyle, under the specified stock ID. * gtk/gtkstyle.h, gtk/gtkstyle.c: Add a virtual function render_icon used to derive a GdkPixbuf from a GtkIconSource.

(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.

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.

Patch from Bill Haneman (with many modifications) to make the focus color Mon Dec 3 16:39:17 2001 Owen Taylor <otaylor@redhat.com> Patch from Bill Haneman (with many modifications) to make the focus color work on dark themes and to make the focus line width configurable. (#61079, #63074) * gtk/gtkwidget.c: Add style properties, ::focus-widget, ::focus-line-width, and ::focus-padding. * gtk/gtkstyle.[ch]: Make gtk_paint_focus() take a state argument as well so we can use fg[STATE] to draw instead of always drawing with black. Cange paint_focus() to respect GtkWidget::focus-width and GtkWidget::focus-line-pattern. Fix continuity problem where the default 1-1 stipple had a blob in one corner and a gap in the other. Change the interpretation of x/y/width/height to be the bounding box of the focus rect instead of the rectangle passed to gdk_draw_rectangle. * gtk/gtkcheckbutton.c gtk/gtklistitem.c gtk/gtknotebook.c gtk/gtkoptionmenu.c gtk/gtkradiobutton.c gtk/gtkspinbutton.c gtk/gtktextview.c gtk/gtktreeview.c: Handle ::focus-width and ::focus-line-padding. * gtk/gtkentry.c: Handle :;focus-width property; cleanup and remove duplicated code; fix drawing of focus rectangle when interior-focus = FALSE. (#63072, #63073) * gtk/gtkrange.c gtk/gtktext.c gtk/gtktreeitem.c gtk/gtktreeviewcolumn.c: Basic fixups to make compile; Range and TreeViewColumn will need more extensive fixing. * gtk/gtkcolorsel.c: Honor focus line attributes when drawing the focus on the color swatches. (#63071) * gtk/gtkhsv.c: Honor focus line attributes when drawing the focus for the ring and triangle. * docs/widget_geometry.txt: Start at documenting how various widgets are drawn. * gtk/gtkbutton.c (_gtk_button_paint): Export _gtk_button_paint() librarywide, so we don't have duplicate a bunch of code in gtktogglebutton.c. * gtk/gtktogglebutton.c: Use _gtk_button_paint().
