This function will generate a button click (button press and button release event) in the middle of the first GdkWindow found that belongs to widget. For windowless widgets like #GtkButton (which returns false from gtk.widget.Widget.getHasWindow), 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 location, see gdk.global.testSimulateButton for details.
