If your project already has GUI code, here are some tips to make migration painless:
- Extract maxGUI events from the window procedure's message handlers. If you don't do this, you will likely find the message handler is no longer triggered. For example:
case WM_CLOSE:
PostQuitMessage(0);
return 0;
should become
void MyForm::OnClosed(maxGUI::FormConcept* /*form*/) noexcept {
maxGUI::PostExitMessage(0);
}
Here is a table of Win32 message types and their respective maxGUI events:
| WM_* | maxGUI event |
|---|---|
| WM_CREATE | OnCreated |
| WM_CLOSE & WM_DESTROY | OnClosed |
| WM_SIZE | OnResized |
- Any extra WM_s can all be handled inside the escape hatch, MyForm::OnWindowMessage().
