Hi,
Thanks for the reply.
The code for HoverButton class is almost same as I posted in the first email
with the exception that in the following method I was removing trackingArea
before releasing it.
- (void)updateTrackingAreas
{
if (trackingArea) {
[self removeTrackingArea:trackingArea];// its there in the code that I
have
[trackingArea release];
trackingArea = nil;
}
[self ensureTrackingArea];
[self addTrackingArea:trackingArea];
[super updateTrackingAreas];
}
mouseEntered: and mouseExited: and other methods do not touch the trackingArea
at all.
This puzzled me and so I asked whether the tab view showing these button
changing tab item to another and thus making these buttons invisible would have
any repercussions. Or calling [super updateTrackingAreas]; at the beginning or
end of the method updateTrackingAreas would make any difference.
Another was any ill effect of removing and adding tracking area, which I am not
doing now as the button is not resizable.
Thanks,
Nick
