Dynamic text labels in NIB file

Question

Hi Guys

I created a nib file and want to display dynamic text messages on it like file names that are selected or the no of files selected etc. Is there a way to to this?

I know this can be done for alert panels but i want it on my custom sheets.

Thanks

Either create connections between your NSTextField elements and your controller class and then set the labels programmatically (using setStringValue).

Or you could consider using bindings. See http://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/CocoaBindings/CocoaBindings.html.

You can create a NSTextField programmatically like this:

(IBAction)showText:(id)sender {
    NSRect frame = NSMakeRect(50, 50, 200, 100);
    NSTextField *tf = [[NSTextField alloc] initWithFrame:frame];
    [tf setStringValue:@"test"];
    [tf setSelectable:NO];
    [tf setEditable:NO];
    [tf setBordered:NO];
    [tf setDrawsBackground:NO];
    [[[sender window] contentView] addSubview:tf];
    [tf release];
}

or you could use NSString's methods for drawing text in a view, namely -drawAtPoint or -drawInRect
