simple controls. More complex controls, such as wxTreeCtrl, have separate command event classes.

wxCommandEvent::wxCommandEvent
wxCommandEvent(WXTYPE commandEventType = 0, int id = 0)
Constructor.
wxCommandEvent::Checked
bool Checked() const
Deprecated, use IsChecked instead.
wxCommandEvent::GetClientData
void* GetClientData()
Returns client data pointer for a listbox or choice selection event
(not valid for a deselection).
wxCommandEvent::GetClientObject
wxClientData * GetClientObject()
Returns client object pointer for a listbox or choice selection event
(not valid for a deselection).
wxCommandEvent::GetExtraLong
long GetExtraLong()
Returns extra information dependant on the event objects type.
If the event comes from a listbox selection, it is a boolean
determining whether the event was a selection (true) or a
deselection (false). A listbox deselection only occurs for
multiple-selection boxes, and in this case the index and string values
are indeterminate and the listbox must be examined by the application.
wxCommandEvent::GetInt
int GetInt()
Returns the integer identifier corresponding to a listbox, choice or
radiobox selection (only if the event was a selection, not a
deselection), or a boolean value representing the value of a checkbox.
wxCommandEvent::GetSelection
int GetSelection()
Returns item index for a listbox or choice selection event (not valid for
a deselection).
wxCommandEvent::GetString
wxString GetString()
Returns item string for a listbox or choice selection event (not valid for
a deselection).
wxCommandEvent::IsChecked
bool IsChecked() const
This method can be used with checkbox and menu events: for the checkboxes, the
method returns true for a selection event and false for a
deselection one. For the menu events, this method indicates if the menu item
just has become checked or unchecked (and thus only makes sense for checkable
menu items).
wxCommandEvent::IsSelection
bool IsSelection()
For a listbox or similar event, returns true if it is a selection, false if it
is a deselection.
wxCommandEvent::SetClientData
void SetClientData(void* clientData)
Sets the client data for this event.
wxCommandEvent::SetClientObject
void SetClientObject(wxClientData* clientObject)
Sets the client object for this event. The client object is not owned by the event
object and the event object will not delete the client object in its destructor.
The client object must be owned and deleted by another object (e.g. a control)
that has longer life time than the event object.
wxCommandEvent::SetExtraLong
void SetExtraLong(long extraLong)
Sets the m_extraLong member.
wxCommandEvent::SetInt
void SetInt(int intCommand)
Sets the m_commandInt member.
wxCommandEvent::SetString
void SetString(const wxString& string)
Sets the m_commandString member.
