Leo has been behaving very strangely lately. Sometimes Alt-A
(sort-headlines) didn't work. The effect was terrifying: Leo's body pane
lost focus. Everything seemed broken. Even the minibuffer didn't always
work.
This morning I added a heavyweight debugging tool,
leoQtEventFilter.traceWidget, which traces events in various ways.
I added a script button:
@button toggle-debug:
g.app.debug_app = not g.app.debug_app
g.app.debug_widgets = not g.app.debug_widgets
print('g.app.debug_app: %s' % g.app.debug_app)
print('g.app.debug_widgets: %s' % g.app.debug_widgets)
Just now the horror happened again. I clicked the button. Instantly I saw
that a QCheckBox had focus.
Huh? Doh! Alt-A was toggling the Wrap-Around box in the Find pane!
This would also explain why Alt-X didn't bring up the minibuffer!
Isn't this a perfect example of H. H. Dow's "that's just what I wanted"
attitude?
This terrifying bug
a) has a simple cause (not fixed yet) and
b) Leo now has a truly powerful new debugging method.
Check out traceWidget. It's good.
