How to disconnect QxtGlobalShortcut?

Hi,
Please don't multi-post your question.
With only that code it's not really clear why you would have a crash.
So a wild guess, are you sure shortcut is not a shadowed variable ?
When you delete/disconnect your shortcut, are you sure it's valid ? -

Sorry for multi-post.
Actually, the program crash at the first line of
@
if(shortcut)
delete shortcut;
@This is what I mean access. Really strange.
Thanks,

Again, making guesses:
You're not creating your shortcut in the class constructor, so the pointer value is an address to a random block of memory.Initialize shortcut (and any other pointer class variable that are not allocated in the constructor) to 0

I do that in constructor.
@
shortcut = 0;
@and then
@
shortcut = new QxtGlobalShortcut();
connect(shortcut, SIGNAL(activated()), this, SLOT(shortcutCallBack()));
shortcut->setShortcut(QKeySequence("Ctrl+Shift+F12"));
@after construction, a UI event call a function, in that function is
@
if(shortcut)
delete shortcut;
@It's really weird, so I post here to see if there is any other possibility.
Thanks,
Cid

Hum...
Your function could be called several times and you didn't set shortcut to 0 after deleting it.
