Basically my question is:
How can you address a specific window with the orderOut, makeKeyAndOrderFront in Cocoa?

The detailed situation is as follows:
I have a panel named "panel" on the left side, a "mainWindow1" in the center. And depending on the user´s input I want to create 1 to 4 "userpanels#" with a tiff or jpeg image in each of them under the mainWindow1.
Now my problem is. When a user presses a button in the "mainWindow1" this mainWindow1 should be ordered out and another window: "mainWindow2" should appear in it´s place. Also at the same time the "userpanels#" should disappear from screen and one of the four panels returns left of the middle (preferably in a slightly larger size).
From the panel it should be possible to restore the old situation again (but if I know it for the first method then this will be just the same).

I already created an outlet: -IBOutlet and hooked it up to the 1 windowcontroller I have. However I am unable to define the right action.
I have no clue on how to address a specific window to disappear or another to makeKeyAndOrderFront.

I read about windowNumber, but that only gives the window number of the window list. I still then don´t know if I have the right window.

But how can you address these particular windows?
Or do I need to create a windowController class for each window and connect the controller to that window only?

What does the -(void)setWindowController actually do? there is no subscription yet. :-(

Please give the function arguments required and in which (windowController) files they should be.
Thanks heaps.

You have outlets to the window so you can just do something like:

[outletName makeKeyAndOrderFront:nil];

and your window will appear and be key. Same thing for orderOut.

Thanks, I got it to work.
I have a follow up question.

How exactly do I have to type the function call or message
to be able to have an implementation file A first call a window
controller B, so that this window controller B is the one who
orders the window to the back and front?

You just do something like:

[windowController showWindow:nil];

in order to show it. If you want to make it disappear fron the screen without closing it then I guess that you'll have to call:

[[windowController window] orderOut:nil];

But if you want to close it you can use the close method in NSWindowController.
