Hi,

I override the drawTickMarks() in NSSliderCell.
However, I need to draw some text there and may have a little outside the NSSlider's boundary, so I got some clip in my result.

I try to set the maskToBound to false by

     self.controlView?.wantsLayer = true
    self.controlView?.layer?.masksToBounds = false
    self.controlView?.layer?.backgroundColor = CGColor(red: 1.0, green: 0.0, blue: 0.0, alpha: 0.5)

So I can clearly see the bounds of slider but the masksToBounds didn't work here.

Does anybody know to make the masksToBounds work for my purpose?

Thank you~~

I did this, with a slider named sliderWithTicks.cell

Code Block         sliderWithTicks.cell?.controlView?.wantsLayer = true
        sliderWithTicks.cell?.controlView?.layer?.masksToBounds = false
        sliderWithTicks.cell?.controlView?.layer?.backgroundColor = CGColor(red: 1.0, green: 0.0, blue: 0.0, alpha: 0.5)
        let text = NSTextField(string: "  1     2     3     4")
        text.frame = NSRect(x: 0, y: -16, width: 100, height: 24)
        text.drawsBackground = false
        text.isBezeled         = false
        text.isEditable        = false
        sliderWithTicks.cell?.controlView?.addSubview(text)
