gboolean gtk_test_widget_click ( GtkWidget* widget, guint button, GdkModifierType modifiers )
This function will generate a
button click (button press and button
release event) in the middle of the first GdkWindow found that belongs
For windowless widgets like
GtkButton (which returns
gtk_widget_get_has_window()), this will often be an
input-only event window. For other widgets, this is usually widget->window.
Certain caveats should be considered when using this function, in
particular because the mouse pointer is warped to the button click
gdk_test_simulate_button() for details.
This testing infrastructure is phased out in favor of reftests.
