When a view contains an NSTextField with the expansion tooltip enabled and the text doesn't fit, then the user hovers the cursor over the field, OS X shows an expansion tooltip. If you then call setStringValue: to change the text content of the NSTextField , the expansion tooltip's size is not updated. For instance, if the original text was 100 characters long but the new text is only 50 characters long, hovering over the new text will show an expansion tooltip large enough for 100 characters containing the new text. This is true even if the new string fits entirely in the NSTextField , which

I have an NSTextField that contains an NSAttributedString which itself contains a clickable link. I've change the colour of the link for my own styling, however when I click on it it becomes blue and underlined. How can I stop this? Seems that I'm not the only one with this problem, and there's a handy class to solve it: https://github.com/laevandus/NSTextFieldHyperlinks This ( http://developer.apple.com/library/mac/#qa/qa1487/_index.html ) may help you. It will show you how to set/change the blue link color and the underlineAttribute. You may also have a look at the methods

I have read many answers to questions about dynamically resizing NSWindows and nothing has quite worked yet. I have built a 'popover' like window to be displayed form the menu bar, I couldn't use NSPopover because it isn't quite customisable enough in terms of design. My view hierarchy current looks like this: NSWindow Subclass - NSView (clears the titlebar rendering, draws popover arrow) - NSView (contentView) - NSOutlineView (main table of content) - NSView (window footer) What I need is for the window to expand and contract with items in the NSOutlineView expanding and contracting, so that

I would like an NSPopUpButton to display a different title than the title of the menu item that is selected. Suppose I have an NSPopUpButton that lets the user pick a list of currencies, how can I have the collapsed/closed button show only the currencies abbreviation instead of the menu title of the selected currency (which is the full name of the currency)? I imagine I can override draw in a subclass (of NSPopUpButtonCell ) and draw the entire button myself, but I would prefer a more lightweight approach for now that reuses the system's appearance. The menu items have the necessary

I have implemented a collection view on my Cocoa app following Ray Wenderlich's tutorial (very helpful, given how buggy and broken Apple's API is in this area). In the tutorial, the collection view's canvas is colored black using the following code (all code is in view controller class' viewDidLoad() method): collectionView.layer?.backgroundColor = NSColor.black.cgColor However, the area that "peeks" when you overshoot ("rubber-band") the scroll using -for example- a magic mouse/scrollwheel, is still white and very distracting: I'm trying to make the whole content area black. In my storyboard,
