Or, do I have to do some more preparations. All view objects in my program was created by IB and I've hooked up the proper target/action & outlet/panel connections, but I get an warning message with the following - displayresultpanel: sender { [ resultpanel display]; return self; } where the warning message states that ' can not find method' ( I assume display) and another warning message : 'return type for display defaults to id' When I run the compiled program, clicking on the button does not bring up the panel. Any help would be greatly appreciated. == Nasir >From: mahesh@ndmath.UUCP (Mahesh)

In the above example you say the "resultpanel" instance variable is a object of class Panel; in that case, you should have a #import <appkit/Panel.h> at the top of the above .m file. This will assure that all Panel methods are known to the compiler, and if you get any warnings, you are indeed calling a method that doesn't exist. The method that makes panels and windows to come on-screen is whole panel, including the border view and the content view, and all subviews. orderFront: simply brings the panel on screen. Because orderFront: is a target-action method, you can usually connect a button or menu item to a panel or window without having to create a glue method; in the above case you wouldn't need the displayresultpanel: method, for instance.

However, since I want to record that the button was clicked in a log file that records such events, it seems to me I can't go directly from the clicked button to the panel, but must interject an intermediate object for that extra processing. Do you know of any other way I could do it? Thanks a lot, Nasir Amra -=- Nasir K. Amra amra@cis.ohio-state.edu >From: joe@mathcs.emory.edu (Joe Christy)
