This works perfectly. However when my app starts with the mouse over

back over.
How do I get mouseMoved events when my app starts up with the mouse
over the view? Where do I place the [ [self window]
setAcceptsMouseMovedEvents:YES] ?
I solved this problem once by overriding -viewDidMoveToWindow, calling
the method to set up the tracking rects in the override, and in the
method that sets up the tracking rects I made it check the current
mouse position and call -mouseEntered: manually if the pointer is
already inside the rect. This works for me...
It may be better to obtain a correct value for the assumeInside
parameter:
- (void)viewDidMoveToWindow
{
NSWindow* theWindow = [self window];
if (theWindow != nil)
{
NSPoint theMouseLocation = [theWindow
mouseLocationOutsideOfEventStream];
NSRect theBounds = [self bounds];
BOOL theAssumeInsideFlag = NSMouseInRect (
[self convertPoint:theMouseLocation fromView:nil],
theBounds, YES);
... your call to addTrackingRect here ...
if (theAssumeInsideFlag)
{
[theWindow setAcceptsMouseMovedEvents:YES];
}
}
}
