NSPopover 显示相对于 NSStatusItem

Question

This is my code:

if #available(OSX 10.10, *) {
    if let b = statusItem.button {
        popover.showRelativeToRect(b.bounds, ofView: b, preferredEdge: .MinY)
    }
} else {
}

The else block is for OS X Mavericks because NSStatusItem.button is not available. Is there a simple way of showing the popover relative to the status item? If not, is it possible to show the popover in the center of the screen instead without the arrow?

Answer 1

before you had access to the statusitem button you had to provide your own view. Then all works the same

to retain the original behaviour, draw a custom view that looks like a status item ;)

eg

@interface DDQuickMenuStatusItemView : NSView
@property(weak) NSStatusItem *item;
//...
@end


@implementation DDQuickMenuStatusItemView

//...

- (void)drawRect:(NSRect)dirtyRect {
    NSImage *image = nil;
    if(self.item) {
        [self.item drawStatusBarBackgroundInRect:self.bounds withHighlight:NO];
        image = self.item.image;
    }

    if(image) {
        NSRect r = self.bounds;
        r.size = [image size];
        r = [self.class centerRect:r inRect:self.bounds];
        r = [self centerScanRect:r];
        [image drawInRect:r fromRect:NSZeroRect operation:NSCompositeSourceOver fraction:1];
    }
}

#pragma mark -

+ (CGRect)centerRect:(CGRect)rect inRect:(CGRect)inRect
{
    CGRect result = rect;
    result.origin.x = inRect.origin.x + (inRect.size.width - result.size.width)*0.5f;
    result.origin.y = inRect.origin.y + (inRect.size.height - result.size.height)*0.5f;
    return result;
}

@end

Note that the view is a sample and not production ready ;)
