Function gtk::test_widget_send_key

pub fn test_widget_send_key(
    widget: &impl IsA<Widget>, 
    keyval: u32, 
    modifiers: ModifierType
) -> bool

This function will generate keyboard press and release events in the middle of the first GdkWindow found that belongs to widget. For windowless widgets like Button (which returns false from WidgetExt::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 key press location, see gdk_test_simulate_key() for details.

widget

Widget to generate a key press and release on.

keyval

A Gdk keyboard value.

modifiers

Keyboard modifiers the event is setup with.

Returns

whether all actions neccessary for the key event simulation were carried out successfully.
