/**
    @class wxToggleButton

    wxToggleButton is a button that stays pressed when clicked by the user. In
    other words, it is similar to wxCheckBox in
    functionality but looks like a wxButton.

    Since wxWidgets version 2.9.0 this control emits an update UI event.

    You can see wxToggleButton in action in the sixth page of the
    controls() sample.

    @beginEventTable{wxCommandEvent}
    @event{EVT_TOGGLEBUTTON(id, func)}
           Handles a toggle button click event.
    @endEventTable
