override \helpref{wxApp::OnInit}{wxapponinit}.

when the frame is iconized.
A \helpref{wxPanel}{wxpanel} is used to place controls (classes derived from \helpref{wxControl}{wxcontrol})
\rtfsp\helpref{wxCheckBox}{wxcheckbox}, \helpref{wxChoice}{wxchoice}, \helpref{wxListBox}{wxlistbox},
\rtfsp\helpref{wxRadioBox}{wxradiobox}, \helpref{wxSlider}{wxslider}.

+Instances of \helpref{wxDialog}{wxdialog} can also be used for controls and they have
the advantage of not requiring a separate frame.
Instead of creating a dialog box and populating it with items, it is possible to choose
one of the convenient common dialog classes, such as \helpref{wxMessageDialog}{wxmessagedialog}\rtfsp
and \helpref{wxFileDialog}{wxfiledialog}.

the base for \helpref{wxClientDC}{wxclientdc}, \helpref{wxPaintDC}{wxpaintdc}, \helpref{wxMemoryDC}{wxmemorydc}, \helpref{wxPostScriptDC}{wxpostscriptdc},

+\rtfsp\helpref{wxMemoryDC}{wxmemorydc}, \helpref{wxMetafileDC}{wxmetafiledc} and \helpref{wxPrinterDC}{wxprinterdc}.
If your drawing functions have {\bf wxDC} as a parameter, you can pass any of these DCs
to the function, and thus use the same code to draw to several different devices.
You can draw using the member functions of {\bf wxDC}, such as \helpref{wxDC::DrawLine}{wxdcdrawline}\rtfsp
-and \helpref{wxDC::DrawText}{wxdcdrawtext}. Control colour on a canvas (\helpref{wxColour}{wxcolour}) with
+and \helpref{wxDC::DrawText}{wxdcdrawtext}. Control colour on a window (\helpref{wxColour}{wxcolour}) with
brushes (\helpref{wxBrush}{wxbrush}) and pens (\helpref{wxPen}{wxpen}).
To intercept events, you add a DECLARE\_EVENT\_TABLE macro to the window class declaration,
and put a BEGIN\_EVENT\_TABLE ... END\_EVENT\_TABLE block in the implementation file. Between these
macros, you add event macros which map the event (such as a mouse click) to a member function.
-These might override predefined event handlers such as \helpref{wxWindow::OnChar}{wxwindowonchar} and
-\rtfsp\helpref{wxWindow::OnMouseEvent}{wxwindowonmouseevent}.
+These might override predefined event handlers such as for \helpref{wxKeyEvent}{wxkeyevent} and
+\rtfsp\helpref{wxMouseEvent}{wxmouseevent}.
Most modern applications will have an on-line, hypertext help system; for this, you
-need wxHelp and the \helpref{wxHelpInstance}{wxhelpinstance} class to control

You will undoubtedly need some platform-independent \helpref{file functions}{filefunctions},
and you may find it handy to maintain and search a list of paths using \helpref{wxPathList}{wxpathlist}.
There's a \helpref{miscellany}{miscellany} of operating system and other functions.
-If you have several communicating applications, you can try out the DDE-like functions, by
-using the three classes \helpref{wxDDEClient}{wxddeclient}, \helpref{wxDDEServer}{wxddeserver} and
-\rtfsp\helpref{wxDDEConnection}{wxddeconnection}. These use DDE under Windows, and a simulation using
-sockets under UNIX.
