Re: [Sc-devel] Transparent backgrounds in Views

[Sciss <contact@xxxxxxxx>]

on a related issue, jan, i wanted to ask you if you think it's  
possible to change the z-order of gadgets in cocoa GUI. the problem  
is things like the example from thor:

GUI.cocoa;
GUI.swing;
(
var size;
size = 12;
a = GUI.window.new("test", Rect(200 , 450, 10 + (size * 17), 10 +  
(size * 17))).front;


b = GUI.slider2D.new(a, Rect(0, 0, size * 17, size * 17))
	.knobColor_(Color.blue)
	.x_(0.8)
	.background_(Color.green.alpha_(0.0))
//	.fillColor_(Color.blue);
	;

c = GUI.slider2D.new(a, Rect(0, 0, size * 17, size * 17))
	.knobColor_(Color.red)
	.x_(0.4)
	.background_(Color.green.alpha_(0.0))
)

they are identical in cocoa and swing, but in cocoa the red slider  
receives mouse actions, in swing the blue one; that is, i adopted the  
z-ordering of cocoa by putting earlier created views in front of  
those created later, but i have no influence on the mouse tracking  
(java is doing that for me), so gadgets painted in front of others  
have priority regarding mouse tracking. i think that behaviour is  
logical. so my question is if it would be possible to

a) reverse the drawing order of gadgets in cocoa GUI without  
reversing the mouse priorities
b) alternatively, reversing the mouse priorities without reversing  
the drawing order

if this is solved, people could safely use layered gadgets with both  
GUI kits... i think variant a) is better because it kind of sounds  
logical that views created later appear on top of old ones.

as i said, in SwingGUI i cannot decouple the painting and mouse focus  
order, so if that's possible in the cocoa GUI, it would be quite  
useful IMO...

ciao, -sciss-
