+/**
+ @class wxCommandEvent
+
+ This event class contains information about command events, which originate
+ from a variety of simple controls.
+
+ Note that wxCommandEvents and wxCommandEvent-derived event classes by default
+ and unlike other wxEvent-derived classes propagate upward from the source
+ window (the window which emits the event) up to the first parent which processes
+ the event. Be sure to read @ref overview_events_propagation.
+
+ More complex controls, such as wxTreeCtrl, have separate command event classes.
+
+ @beginEventTable{wxCommandEvent}
+ @event{EVT_COMMAND(id, event, func)}
+ Process a command, supplying the window identifier, command event identifier,
+ and member function.
+ @event{EVT_COMMAND_RANGE(id1, id2, event, func)}
+ Process a command for a range of window identifiers, supplying the minimum and
+ maximum window identifiers, command event identifier, and member function.
+ @event{EVT_BUTTON(id, func)}
+ Process a @c wxEVT_BUTTON command, which is generated by a wxButton control.
+ @event{EVT_CHECKBOX(id, func)}
+ Process a @c wxEVT_CHECKBOX command, which is generated by a wxCheckBox control.
+ @event{EVT_CHOICE(id, func)}
+ Process a @c wxEVT_CHOICE command, which is generated by a wxChoice control.
+ @event{EVT_COMBOBOX(id, func)}
+ Process a @c wxEVT_COMBOBOX command, which is generated by a wxComboBox control.
+ @event{EVT_LISTBOX(id, func)}
+ Process a @c wxEVT_LISTBOX command, which is generated by a wxListBox control.
+ @event{EVT_LISTBOX_DCLICK(id, func)}
+ Process a @c wxEVT_LISTBOX_DCLICK command, which is generated by a wxListBox control.
+ @event{EVT_CHECKLISTBOX(id, func)}
+ Process a @c wxEVT_CHECKLISTBOX command, which is generated by a wxCheckListBox control.
+ @event{EVT_MENU(id, func)}
+ Process a @c wxEVT_MENU command, which is generated by a menu item.
+ @event{EVT_MENU_RANGE(id1, id2, func)}
+ Process a @c wxEVT_MENU command, which is generated by a range of menu items.
+ @event{EVT_CONTEXT_MENU(func)}
+ Process the event generated when the user has requested a popup menu to appear by
+ pressing a special keyboard key (under Windows) or by right clicking the mouse.
+ @event{EVT_RADIOBOX(id, func)}
+ Process a @c wxEVT_RADIOBOX command, which is generated by a wxRadioBox control.
+ @event{EVT_RADIOBUTTON(id, func)}
+ Process a @c wxEVT_RADIOBUTTON command, which is generated by a wxRadioButton control.
+ @event{EVT_SCROLLBAR(id, func)}
+ Process a @c wxEVT_SCROLLBAR command, which is generated by a wxScrollBar
+ control. This is provided for compatibility only; more specific scrollbar event macros
+ should be used instead (see wxScrollEvent).
+ @event{EVT_SLIDER(id, func)}
+ Process a @c wxEVT_SLIDER command, which is generated by a wxSlider control.
+ @event{EVT_TEXT(id, func)}
+ Process a @c wxEVT_TEXT command, which is generated by a wxTextCtrl control.
+ @event{EVT_TEXT_ENTER(id, func)}
+ Process a @c wxEVT_TEXT_ENTER command, which is generated by a wxTextCtrl control.
+ Note that you must use wxTE_PROCESS_ENTER flag when creating the control if you want it
+ to generate such events.
+ @event{EVT_TEXT_MAXLEN(id, func)}
+ Process a @c wxEVT_TEXT_MAXLEN command, which is generated by a wxTextCtrl control
+ when the user tries to enter more characters into it than the limit previously set
+ with SetMaxLength().
+ @event{EVT_TOGGLEBUTTON(id, func)}
+ Process a @c wxEVT_TOGGLEBUTTON event.
+ @event{EVT_TOOL(id, func)}
+ Process a @c wxEVT_TOOL event (a synonym for @c wxEVT_MENU).
+ Pass the id of the tool.
+ @event{EVT_TOOL_RANGE(id1, id2, func)}
+ Process a @c wxEVT_TOOL event for a range of identifiers. Pass the ids of the tools.
+ @event{EVT_TOOL_RCLICKED(id, func)}
+ Process a @c wxEVT_TOOL_RCLICKED event. Pass the id of the tool. (Not available on wxOSX.)
+ @event{EVT_TOOL_RCLICKED_RANGE(id1, id2, func)}
+ Process a @c wxEVT_TOOL_RCLICKED event for a range of ids. Pass the ids of the tools. (Not available on wxOSX.)
+ @event{EVT_TOOL_ENTER(id, func)}
+ Process a @c wxEVT_TOOL_ENTER event. Pass the id of the toolbar itself.
+ The value of wxCommandEvent::GetSelection() is the tool id, or -1 if the mouse cursor
+ has moved off a tool. (Not available on wxOSX.)
+ @event{EVT_COMMAND_LEFT_CLICK(id, func)}
+ Process a @c wxEVT_COMMAND_LEFT_CLICK command, which is generated by a control (wxMSW only).
+ @event{EVT_COMMAND_LEFT_DCLICK(id, func)}
+ Process a @c wxEVT_COMMAND_LEFT_DCLICK command, which is generated by a control (wxMSW only).
+ @event{EVT_COMMAND_RIGHT_CLICK(id, func)}
+ Process a @c wxEVT_COMMAND_RIGHT_CLICK command, which is generated by a control (wxMSW only).
+ @event{EVT_COMMAND_SET_FOCUS(id, func)}
+ Process a @c wxEVT_COMMAND_SET_FOCUS command, which is generated by a control (wxMSW only).
+ @event{EVT_COMMAND_KILL_FOCUS(id, func)}
+ Process a @c wxEVT_COMMAND_KILL_FOCUS command, which is generated by a control (wxMSW only).
+ @event{EVT_COMMAND_ENTER(id, func)}
+ Process a @c wxEVT_COMMAND_ENTER command, which is generated by a control.
