how to get window with semi-transparent blurred background

Question

I\'d like to get a window that has a semi-transparent blurred background, just like what the Terminal can do. See this video, about 30 sec in, to see what I mean: http://www.you

Answer 1

no need for layers and filters, NSWindow can do it itself

[mywindow setOpaque:NO];
[mywindow setBackgroundColor: [NSColor colorWithCalibratedHue:0.0 saturation:0.0 brightness:0.2 alpha:0.5]];

please do not use this, as it will alpha your title bar also (post it here just in case others need)

[mywindow setOpaque:NO];
[mywindow setBackgroundColor: [NSColor blackColor]];
[mywindow setAlphaValue:0.5];
