How to implement window fade-in fade-out effects
-
Hello List,
I need someone to push me in the right direction as I have no idea
where to start:
I have an existing window which I'd like to show and hide using a
zooming transition effect. I'd like something similar to the one in
iCal (on Leopard) when you double click a calendar entry or in Finder
when you press SPACE on an item an the QuickLook window becomes
visible (same for hiding). How does one go about that?
I'm on 10.5.3 and I'm targeting 10.5. Right now I'm showing the window
using orderFrontAndMakeKey: and orderOut:
Thanks for any pointers.

The window's frame is an animatable property, so you could try
something like this:
- (void)showWindow:(id)window
{
NSRect startFrom = NSZeroRect;
NSRect endAt = [window frame];
CGFloat duration = 5.0;
[window setFrame:startFrom display:NO];
[window orderFrontAndMakeKey:nil];
[NSAnimationContext beginGrouping];
[[NSAnimationContext currentContext] setDuration:duration];
[[window animator] setFrame:endAt display:YES];
[NSAnimationContext endGrouping];
}

There's actually an even simpler method which predates Core Animation,
setFrame:display:animate:.

Just curious if some frameworks have been thought of for Animation. In
the likes of Jquery or others. For example
window.show(fade_in, slow);
That way animations can be very clean and simple to write and test. -

Isn't what CoreAnimation does ? -

Core Animation available on Mac OS X 10.5 and later.

Carbon has an API that does this: TransitionWindow(). You can take a
look at its docs. It supports the genie effect and others. There is no
equivalent Cocoa API.
Matt Ball wrote some Cocoa code that uses this:

Alas, TransitionWindow() is deprecated and not available in 64. So
really I don't recommend it.

That'll work, but in my experience if any of the controls in the window
make use of 'autoresizing springs' then they will resize incorrectly if
starting from a window size smaller that the control's minimum size.

Technically speaking, it's not deprecated (at least it's not marked a
such in the documentation). If you don't need 64-bit support, it might
just be the most convenient option.

I suppose. It's 'almost deprecated' then. :) Eventually, Mac OS will
be 64 bit only, so if something is 32 bit only, I'd stay away.> If you don't need 64-bit support, it might

It might, which is why I brought it up.

I'll keep that in mind, thanks for mentioning. The window that I
animate doesn't resize and the controls on it don't use springs so it
appears to be safe in this respect.
