Can anyone let me know what is wrong in the code? Attaching the code along with this mail. Another thing that you may want to look into is NSWindowController... especially in this simple case, I think it's a better choice than your own subclass of NSObject. For just this simple about panel, you probably wouldn't even need to subclass it. To use it, just create it with your window nib and in your window nib make file's owner an instance of NSWindowController or (if you decide to subclass it) an instance of your subclass. You can read more about NSWindowController at: http://developer.apple.com/documentation/Cocoa/Reference/ApplicationKit/Classes/NSWindowController_Class/Reference/Reference.html Jason smime.p7s Description: S/MIME cryptographic signature ___ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.

Since you're loading the instance yourself, you don't want to create the AboutPanelController object *inside* the nib. This is what the File's Owner object is for. To correct your issue keeping (mostly) the same code as in your small example project, make these changes: In AbouPanel.nib: 1) Delete the instance of AboutPanelController 2) Select File's Owner and open the inspector; under the Identity panel, change the Class to AboutPanelController 3) Wire your File's Owner mPanelToDisplay outlet to the panel in the nib 4) (optional since you don't do any delegate methods at the moment) wire your panel's delegate outlet to File's Owner 5) Save (and optionally quit IB) In AboutPanelController.mm: 1) In the method implementation for sharedInstance, change line 20 to the following line (change marked in bold): if (YES == [NSBundle loadNibNamed:@"AbouPanel.nib" owner:sharedInstance]; 2) save and rebuild -- this should now work as expected In this case, you want your sharedInstance variable to actually be the file's owner so that it can receive messages meant for the panel in the nib. You don't want the class itself to be the file's owner since you're actually creating an instance of the class here.
