Hi, Sebastian!
static gboolean
expose_event(GtkWidget *widget, GdkEventExpose *event)
{
static GtkStyle *style = NULL;
int x = widget->allocation.x;
int y = widget->allocation.y;
int width = widget->allocation.width;
int height = widget->allocation.height;
if (!style)
// key phrase:
style = gtk_rc_get_style_by_paths(gtk_settings_get_default(), NULL,
"GtkButton", GTK_TYPE_BUTTON);
gtk_style_attach(style, widget->window);
gtk_paint_box(style, widget->window,
GTK_STATE_NORMAL,
GTK_SHADOW_OUT, &event->area,
widget, "button",
x, y, width, height);
gtk_style_detach(style);
return FALSE;
}
Style engine may or may not heavily depend on widget's class or even
properties, so don't expect exact emulation for all classes on all
engines. I think it is why things are not documented.
See $SRC/gtk/gtkbutton.c on how to paint button's focus, default, etc
exactly as GtkButton does.
