Blurred background for Main window

[shanmugaraja]

Using QMainWindow, I want to make the main window (root window) to have blurred transparency as like the screenshot I have attached here.

I am able to do this blurred background (Screen behind the window is blurred) using the pure native implementation for Mac using NSVisualEffectView available on Mac in Objective-C.

But i want to implement the same effect using Qt.

MainWindow.mm

- (void)awakeFromNib
{
    [super awakeFromNib];
    [self applyBlurVisualEffect];
}

- (void)applyBlurVisualEffect
{
    NSVisualEffectView *view = [[NSVisualEffectView alloc] initWithFrame:self.contentView.bounds];
    view.blendingMode = NSVisualEffectBlendingModeBehindWindow;
    view.material = NSVisualEffectMaterialDark;
    view.state = NSVisualEffectStateActive;
    [self setContentView:view];

}

Is there any Qt Widget attribute or Application Attribute or any other Qt API available for achieving this effect?

I am attaching the screenshot here and highlighted the window displayed on the bottom center of the screen.

Hi
As far as I know, there is nothing like that in Qt. It can blur widgets but not the actual desktop.
