[wxPython-users] Custom tooltip issues

Well, maybe it is too late for me in the evening to wxPythoning, but I
am unable to get any tooltip visible. If I click on the top panel, I
get a very fast flash of a tooltip that suddenly disappears.

Uhm, you should check if hasattr(self, "tooltip") or you will get a
bunch of AttributeErrors. However, after fixing this, I don't see any
tooltip anywhere, no matter if I click, or wait without moving the
mouse... weird, what's wrong with tooltips?!?!
However, I don't think that the call to Destroy() is safe, I get a lot
of PyDeadObjectErrors... maybe wx.TipWindow behaves like wx.BusyInfo?
You may try to call "del self.tooltip" to see if anything changes.

I can't see any tooltip :-(
This is Windows XP, wxPython 2.7.0.1 latest pre-release, Python 2.4.3.

You may take a look at the BalloonTip control I wrote few months ago.

Ok, it displays ballon-type tips, but this is easily changed. The only
problem I see with custom tooltips, is that they will almost surely
steal the focus from your widget/app, unless you restore the focus
where it was...
