    wxStyledTextCtrl problem ?

    I have a wierd thing with a little editor app I'm writing.

    I'm using wxStyledTextCtr l ; the wrapper for Scintilla. When I create the
    frame in wxPython, I use self.Editor.Set Focus() to put the focus initially
    on the editor.

    This works fine.

    Odd thing is though, switching back and forwards between applications
    alternately hides and reappears the caret.

    Hit Alt-Tab twice and it disappears
    Hit Alt-Tab twice and it comes back.

    It still works fine - there's just no caret. I've tried various things in
    EVT_ACTIVATE including Moving the Caret on screen, and forcing it to be
    visible - they are being called but it makes no difference.

    Any ideas ?

      I don't know why the problem you are having happens, but I would just
      make a call to self.Editor.Set Focus() on an EVT_ACTIVATE event.

          If you are running GTK+ try using

          self.Editor.Set STCFocus(True)

          in addition to or instead of SetFocus(). Plus maybe

          wx.CallAfter(se lf.Editor.Ensur eCaretVisible)

          It solved the 'dissapearing caret' problem for our application.

                  Tried that, it doesn't work :(

                  Or to be precise, it works every other time :)
