wxFileDialog displays current dir now, wxTipProvider uses statictext for headline messagebox (and other) dialogs now always display an OK buttons, unless wxYES_NO is given Appending a menu to a menu bar after having called wxFrame::SetMenuBar() should now work Added test to configure so that it correctly sets compiler flags etc if GCC is used on Solaris and IRIX instead of CC, also changed default shared library create to GCC from G++ on some platforms (as previously already Linux) git-svn-id: https://svn.wxwidgets.org/svn/wx/wxWidgets/trunk@3429 c3d73ce0-8a6f-49c7-b76d-6d57e0e08775

\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{void*}{m\_clientData}
|
|
|
|
Contains a pointer to client data for listboxes and choices, if the event
|
|
was a selection. Beware, this is not implemented anyway...
|
|
|
|
\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::wxCommandEvent}
|
|
|

|
|
Returns item index for a listbox or choice selection event (not valid for
|
|
a deselection).
|
|
|
|
\membersection{wxCommandEvent::GetString}
|
|
|
|
\func{char*}{GetString}{\void}
|
|

Returns item string for a listbox or choice selection event (not valid for

|
|
|
\membersection{wxCommandEvent::SetInt}
|
|
|
|
\func{void}{SetInt}{\param{int}{ intCommand}}
|
|
