Below is simple code for testing Native Win32 Edit control in wxWidgets, no matter if or not I add style WS_EX_CONTROLPARENT or not OR no matter if I add TranslateMessage function, the EDIT control simple does not accept ENTER key and TAB key. I also captured wxEVT_NAVIGATION_KEY and send it to the child window, but it's not working. This seems a basic function. Did I miss someting? (accepting mean showing ENTER and TAB chars in the EDIT box, if you can see the GIF, the message is captured, but no ENTER or TAB chars in the EDIT box)
