Handle EVT_CHAR in wxFrame or wxDialog

As we all know, EVT_CHAR is a basic event which don't propagate to wxTopLevelWindow(wxFrame and wxDialog).

But I have a wxDialog without any wxWidgets controls on it, and need to handle user keyboard input (handle EVT_CHAR event).

I saw the wiki about catch key events globally, but it's not work on EVT_CHAR event as EVT_CHAR event need to be translated to get user input

And I have try to have wxDialog a hided children wxWindow which foward EVT_CHAR to its parent wxDialog. It works on Windows platform, and not on OSX which is my target platform.

Is there a way to implement it ?

Solution

  • Finally, I implemented what I want according to this: http://trac.wxwidgets.org/ticket/15345

    In wxWidgets 3.0, wxNSView implementes NSTextInputClient protocol, which makes every widgets can handle EVT_CHAR correctly.

    But EVT_CHAR still cannnot be handle by wxDialog or wxFrame, because of some call of IsUserPanel() function. So I commented some call of IsUserPanel to make it work for me.
