NSWindow not refreshing

Question

Tested using a xib instead of code and works like a charm. Still think a proper solution and cause should be found. Will keep on updating as needed

Making a popUp window with a NSProgressIndicator to show how a communication process is going.

The problem is that the progressIndicator won't update.

Checked and working:

• alertPopUp is key
• alertPopUp is front most
• alertPopUp receives increment call
• progressIndicator values are updated correctly
• progressIndicator in both alertPopUp and main window, main window progressIndicator bar fills

Checked and not working:

• progressIndicator bar won't fill

Noticed behaviour:

• On 3 fingers swipe up movement, displaying all available windows in system, the alertPopUp window will update once, and only once.

Tested the same code in the main app window and worked perfectly.

If i make the alertPopUp window main won't make a difference.

Ideas are really welcome, completely blocked.

Gonna show you the alertPopUp Code and the caller:

@implementation XTAlertPopUp{
    NSProgressIndicator *progressBar;
    double incrementStep;
}

+ (XTAlertPopUp *)_baseInit:(NSView *)caller delegate:(id<XTAlertPopUpDelegate>)delegate{
    CGRect viewPositionInScreen = [caller.window convertRectToScreen:[caller convertRect:caller.bounds toView:nil]];

    XTAlertPopUp *alertPopUp = [[XTAlertPopUp alloc] initWithContentRect:CGRectMake(viewPositionInScreen.origin.x + ((caller.frame.size.width - windowWidth) * .5), viewPositionInScreen.origin.y + ((caller.frame.size.height - windowHeight) * .5), windowWidth, windowHeight)
                                                               styleMask:NSBorderlessWindowMask
                                                                 backing: NSBackingStoreRetained
                                                                   defer:YES];

    alertPopUp.alertDelegate = delegate;

    return alertPopUp;
}

+ (XTAlertPopUp *)alertProgressCalledFromView:(NSView *)caller withMessage:(NSString *)msg numberOfProgressStages:(NSUInteger)progressStages andCancelButtonTitle:(NSString *)cancelTitle settingDelegate:(id<XTAlertPopUpDelegate>)delegate{
    XTAlertPopUp *alertPopUp = [XTAlertPopUp _baseInit:caller delegate:delegate];

    NSBox *base = [alertPopUp _baseViewForAlert:msg cancelButton:cancelTitle];
    [alertPopUp _buildProgressBarAndAddTo:base numberOfProgressStages:progressStages];

    [alertPopUp setContentView:base];
    [base release];

    return alertPopUp;
}

You can use this to call for testing:

- (void)testprogressBar{
    [self alertPopUpSaveProgress:@(100)];
    [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(increments:) userInfo:@(0) repeats:NO];
}

- (void)increments:(NSTimer *)timer{

    NSNumber *inc = @([[timer userInfo] integerValue] + 1);
    if([inc integerValue] > 99)
        return;
    NSLog(@"patch iskey >> %d || patch is main >> %d", [self.view.window isKeyWindow], [self.view.window isMainWindow]);
    [alertProgress incrementProgress];
    [NSTimer scheduledTimerWithTimeInterval:1 target:self selector:@selector(increments:) userInfo:inc repeats:NO];
}

- (void)alertPopUpSaveProgress:(NSNumber *)numberOfSteps{
    alertProgress = [XTAlertPopUp alertProgressCalledFromView:self.view
                                                        withMessage:@"Saving changes"
                                             numberOfProgressStages:[numberOfSteps unsignedIntegerValue]
                                               andCancelButtonTitle:@"cancel"
                                                    settingDelegate:self];
    [alertProgress shootThreadedAlert];
}
