+    @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
+    @event{EVT_CHECKBOX(id\, func)}:
+           Process a wxEVT_COMMAND_CHECKBOX_CLICKED event, when the checkbox
+           is clicked.
