Artem: this is a good idea, thanks.

Mike: I'm trying to do something like this:


i.e. I'm feeding an NSImage with images of all available sizes.

A sample test provides a list of icons 16x16, 32x32, 48x48, and 64x64. 
I've verified that they all get added into the representations array. 
However, even if I resize the dock to be very very tiny, it still 
chooses the 64x64 icon to represent a minimized window. This is actually 
wrong since the 16x16 icon would look better in this case than a resized 
64x64 icon.

Any idea how this can be fixed?

Another solution would be to take an approach similar to what we use on 
MS Windows: we query the system icon size, and then choose the best 
image (see SunToolkit.getScaledIconData()). But I can't find API that 
would allow me to determine the current dock icon size on OS X. Is there 

best regards,
