I access the window of a view by two different ways, in the controller and in the view, resp., and in the controller, I always get a nil pointer.
In my app, I have a subclass of NSView, MyView, declared like this:
@interface MyView : NSView <NSTextViewDelegate, CALayerDelegate,
CAAnimationDelegate>
{
NSWindow * window_;
...
}
@property (readwrite) NSWindow * window_;
In one of MyView's instance methods, I save the window like this:
- (void) viewWillMoveToWindow: (NSWindow *) newWindow
{
window_ = newWindow;
...
Also in MyView, I have this line to interrogate the styleMask at some point
later during runtime:
if ( [window_ styleMask] & NSWindowStyleMaskFullScreen )
...
This works fine, window_ has a proper value (as a pointer), and styleMask
returns values as expected.
However, I have pretty much the same line in my MasterViewController, which
does not work.
In the MasterViewController, I create an instance of MyView like this:
- (void) viewDidLoad
{
[super viewDidLoad];
myview_ = [[MyView alloc] initWithFrame: self.view.frame isPreview: NO ];
[self.view addSubview: myview_];
...
Then, in MasterViewController's showPreferences:, I have this code:
- (IBAction) showPreferences: (id) sender
{
if ( [myview_.window_ styleMask] & NSWindowStyleMaskFullScreen )
...
Here, myview_.window_ is always 0.
How could that be?
Puzzled, Gabriel.
