Method
GtkWidgetsend_expose
deprecated: 3.22
Declaration [src]
gint
gtk_widget_send_expose (
GtkWidget* widget,
GdkEvent* event
)
Description [src]
Very rarely-used function. This function is used to emit
an expose event on a widget. This function is not normally used
directly. The only time it is used is when propagating an expose
event to a windowless child widget (gtk_widget_get_has_window() is FALSE),
and that is normally done using gtk_container_propagate_draw().
If you want to force an area of a window to be redrawn,
use gdk_window_invalidate_rect() or gdk_window_invalidate_region().
To cause the redraw to be done immediately, follow that call
with a call to gdk_window_process_updates().
Deprecated since: 3.22
Application and widget code should not handle
expose events directly; invalidation should use the GtkWidget
API, and drawing should only happen inside GtkWidget::draw
implementations.
Parameters
