Module Summary

Functions for wxNavigationKeyEvent class

Description

This event class contains information about navigation events, generated by navigation keys such as tab and page down.

This event is mainly used by wxWidgets implementations. A wxNavigationKeyEvent handler is automatically provided by wxWidgets when you enable keyboard navigation inside a window by inheriting it from wxNavigationEnabled<>.

See: wxWindow:navigate/2, wxWindow::NavigateIn (not implemented in wx)

This class is derived (and can use functions) from: wxEvent

wxWidgets docs: wxNavigationKeyEvent
