    @class wxCheckBox
    @wxheader{checkbox.h}

    A checkbox is a labelled box which by default is either on (checkmark is
    visible) or off (no checkmark). Optionally (when the wxCHK_3STATE style
    flag is set) it can have a third state, called the mixed or undetermined
    state. Often this is used as a "Does Not Apply" state.

    @beginStyleTable
    @style{wxCHK_2STATE}
           Create a 2-state checkbox. This is the default.
    @style{wxCHK_3STATE}
           Create a 3-state checkbox. Not implemented in wxMGL, wxOS2 and
           wxGTK built against GTK+ 1.2.
    @style{wxCHK_ALLOW_3RD_STATE_FOR_USER}
           By default a user can't set a 3-state checkbox to the third state.
           It can only be done from code. Using this flags allows the user to
           set the checkbox to the third state by clicking.
    @style{wxALIGN_RIGHT}
           Makes the text appear on the left of the checkbox.
    @endStyleTable

    @beginEventTable{wxCommandEvent}
    @event{EVT_CHECKBOX(id, func)}
           Process a wxEVT_COMMAND_CHECKBOX_CLICKED event, when the checkbox
           is clicked.
