Please help me ! how to fix the position of NSWindow ?

The windowWillUseStandardFrame:defaultFrame: delegate method is not used to position the window, it is used with NSWindow's zoom: method in determining what the window frame can be zoomed to. The initial position of the windows can be set in the Interface Editor, but you will need to post some code and/or a better description about what you are wanting to do.

You will probably need to convert the coordinates, since a window starts at the lower left, but once the initial window is positioned you can use the cascadeTopLeftFromPoint: method - see the Window Programming Guide.

I still can't tell what you are doing. If your window is defined in a nib, then you can use NSWindowController's initWithWindowNibName method, and the position of the initial window would be whatever has been set in the nib (the initial position can be set in the Interface Editor's Size Inspector). The setShouldCascadeWindows method (default is yes) determines if the window should cascade in relation to other document windows. If you are manually positioning your windows, you can use NSWindow's cascadeTopLeftFromPoint method with the initial top left coordinates, and use the returned NSPoint in the next call to cascade that window, and so on.

I find very openly the management of the positioning of a window very complex while it is a basic task !

Thanks.

Bonjour Ounas,

It is not complex, within Cocoa simple things are easy to implement (and complex are possible). If you find it the other way you made a mistake somewhere.

In your case I would start by putting a breakpoint in the methods and run the application in Debugg Mode.

And if :

- your method is not called

- your window is 0x0 inside the method

Closely look in Interface Builder if the connection is correct between your window and its variable in code and if your controller object is well assigned as its delegate. For that just select the window object in the nib and do a right/control click on it to see if it is well connected with controller's objects (alternatively use the Menu -> View -> Utilities -> Show Connections Inspector).

As for the time to call your "fix" method what about the "- (void)windowDidLoad" call in your window controller subclass ?

I had lots of troubles to get it called when I started with Cocoa. For it to works you have to be sure the window is well connected in IB to your window variable. And you need to load that f*¿!^ fichue window by any call to it via your controller like

//After call window is 0x0 in the debugger if you look at it by unfolding the triangles self>controller>NSWindowController

controller = [[RTWindowControlleralloc]init];

//This one will trigger the controller's windowDidLoad method

[controllershowWindow:self];

//a simple [controller window] is enough to bring it to life

Hi,

As I told you before put a breakpoint in your awakeFromNib method and watch the value of your window variable inside this method.

Could be nil because you did not bring it to life at that time. If nil all your work will fail silently because messages sent to nil do fail silently..

You have to call it for it to exists. Maybe it's not off screen but just nil at that moment.

You won't need to do anything in your controller's awakeFromNib unless you are setting up other stuff, but your window should show up at the initial location set in the Interface Editor (note that the coordinates it uses are the bottom left corner) when your application starts up, for example:

AppDelegate.h

@class MyWindowController; @interface AppDelegate : NSObject {     MyWindowController *theWindowController;     MyWindowController *anotherWindowController; } // whatever else @end

AppDelegate.m

- (void)applicationDidFinishLaunching:(NSNotification*)notification {      theWindowController = [[MyWindowController alloc] initWithWindowNibName:@"YourWindow"];      if (theWindowController != NULL)           [theWindowController showWindow:self];                 anotherWindowController = [[MyWindowController alloc] initWithWindowNibName:@"YourWindow"];      if (anotherWindowController != NULL)           [anotherWindowController showWindow:self]; // etcetera }

The other windows should automatically cascade, since that is the default, otherwise you can manually cascade them with the previously mentioned methods.
