Re: NSTableView table contets Deletion problem

The easier way to do it is to assign the shortcut to a menu item, wich invokes your method. Obviously, when the method is called, you'll have to check the selected index(es) of the table view by calling - selectedRowIndexes or -selectedRow. --Luca C. 2009/2/14 Arun > Hi All, > > I have a scree

Hi there! I'm working on an NSTextField subclass (basically I need to change the TextField's appearance so it fits with an HUD style window) So far I've subclass it and overrode drawRect: so that I can draw my custom background... it's working well, however my problem is that when the te

Hey, I have an application which must switch in and out of full screen mode. Going full screen is fine, but when I exit full-screen, my Core Animation components disappear!

Re: Line spacing in NSTextView

Slava, Calculating an optimal vertical layout is pretty involved. At least, the Cocoa Text System has sophisticated logic to determine the ideal layout because of the numerous and varying design target for different fonts. For example, as you found out, many fonts designed in 80s have pr
