/**
    @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 @ref page_samples_controls.

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