- // the explanation of wxEVT_PAINT processing hack: for historic reasons
- // there are 2 ways to process this event in classes deriving from
- // wxScrolledWindow. The user code may
- //
- // 1. override wxScrolledWindow::OnDraw(dc)
- // 2. define its own OnPaint() handler
- //
- // In addition, in wxUniversal wxWindow defines OnPaint() itself and
- // always processes the draw event, so we can't just try the window
- // OnPaint() first and call our HandleOnPaint() if it doesn't process it
- // (the latter would never be called in wxUniversal).
- //
- // So the solution is to have a flag telling us whether the user code drew
- // anything in the window. We set it to true here but reset it to false in
- // wxScrolledWindow::OnPaint() handler (which wouldn't be called if the
- // user code defined OnPaint() in the derived class)
- m_hasDrawnWindow = true;
-
- // pass it on to the real handler
- bool processed = wxEvtHandler::ProcessEvent(event);
+ // Pass it on to the real handler: notice that we must not call
+ // ProcessEvent() on this object itself as it wouldn't pass it to the next
+ // handler (i.e. the real window) if we're called from a previous handler
+ // (as indicated by "process here only" flag being set) and we do want to
+ // execute the handler defined in the window we're associated with right
+ // now, without waiting until TryAfter() is called from wxEvtHandler.
+ bool processed = m_nextHandler->ProcessEvent(event);
