wxStyledTextCtrl problem ?

[Paul Robson]

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

I'm using wxStyledTextCtrl ; the wrapper for Scintilla. When I create the
frame in wxPython, I use self.Editor.SetFocus() 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.SetFocus() on an EVT_ACTIVATE event.

If you are running GTK+ try using

self.Editor.SetSTCFocus(True)

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

wx.CallAfter(self.Editor.EnsureCaretVisible)

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

Here is the recent thread about this particular problem:

Tried that, it doesn't work

Or to be precise, it works every other time

Thanks - that worked perfectly !
