nstextfield

Need to have an NSTextField with a text limit of 4 characters maximum and show always in upper case but can't figure out a good way of achieving that. I've tried to do it through a binding with a validation method but the validation only gets called when the control loses first responder and that's no good. Temporarly I made it work by observing the notification NSControlTextDidChangeNotification on the text field and having it call the method: - (void)textDidChange:(NSNotification*)notification { NSTextField* textField = [notification object]; NSString* value = [textField stringValue]; if (

Auto layout in Lion should make it fairly simple to let a text field (and hence a label) grow with text it holds. The text field is set to wrap in Interface Builder. What is a simple and reliable way to do this? Monolo The method intrinsicContentSize in NSView returns what the view itself thinks of as its intrinsic content size. NSTextField calculates this without considering the wraps property of its cell, so it will report the dimensions of the text if laid out in on a single line. Hence, a custom subclass of NSTextField can override this method to return a better value, such as the one

I have searched extensively and cannot for the life of me find any information about how to achieve a similar effect to that of the iTunes song title scrolling if the text is too large in Cocoa. I have tried setting the bounds on a NSTextField to no avail. I have tried using NSTextView as well as various attempts at using NSScrollView. I am sure I am missing something simple but any help would be greatly appreciated. I am also hoping to not have to use CoreGraphics if at all possible. Example , notice the "Base.FM http://www ." text has been scrolled. If you need a better example open iTunes

Here's the problem: I have some code that goes like this otherWinController = [[NotificationWindowController alloc] init]; for (int i = 0; i < 10; i++) { [otherWinController showMessage:[NSString stringWithFormat:@"%d", i]]; NSLog(@"%d", i); sleep(1); } where otherWinController is a subclass of NSWindowController that I am using to update my window as changes happen in code, and the alloc init method simply opens up the nib and shows the window. showMessage is a method that changes an NSTextView to display whatever text is in the parameter. in the NSLog, the text changes every second and just

I have an application, which open popover with NSTextField . The text field is not editable. Behavior for text field is set to Editable . I still can paste and copy text to this field but i can't edit it. Anyone knows, what can be wrong? Balazs Toth Not sure if you still need the answer, but there may be some others still looking. I found a solution on apple developer forums. Quoting the original author: The main problem is the way keyboard events works. Although the NSTextField (and all its superviews) receives keyboard events, it doesn't make any action. That happens because the view where
