\section{\class{wxCommandEvent}}\label{wxcommandevent}
|
|
|
|
This event class contains information about command events, which originate from a variety of
|
|
simple controls. More complex controls, such as \helpref{wxTreeCtrl}{wxtreectrl}, have separate command event classes.

To process a menu command event, use these event handler macros to direct input to member
|
|
functions that take a wxCommandEvent argument.

\membersection{wxCommandEvent::m\_clientData}
|
|
|
|
\member{char*}{m\_clientData}
|
|
|
|
Contains a pointer to client data for listboxes and choices, if the event
|
|
was a selection.
|
|
|
|
\membersection{wxCommandEvent::m\_commandInt}
|
|
|
|
\member{int}{m\_commandInt}
|
|
|
|
Contains an 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.
|
|
|
|
\membersection{wxCommandEvent::m\_commandString}
|
|
|
|
\member{char*}{m\_commandString}
|
|
|
|
Contains a string corresponding to a listbox or choice selection.
|
|
|
|
\membersection{wxCommandEvent::m\_extraLong}
|
|
|
|
\member{long}{m\_extraLong}
|
|
|
|
Extra information. 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.
|
|

\membersection{wxCommandEvent::GetString}
|
|
|
|
\func{char*}{GetString}{\void}
|
|

\membersection{wxCommandEvent::IsSelection}
|

|
\membersection{wxCommandEvent::SetInt}
|
|
|
|
\func{void}{SetInt}{\param{int}{ intCommand}}
|
|
|
|
Sets the {\bf m\_commandInt} member.
