Hi All,
This is something that I haven't seen before. I have a custom view
that inherits from NSView directly and just draws a gradient
background. In IB I've placed an NSSlider on the view which works
fine. The problem comes when drawRect in my custom view is invoked, I
draw the gradient and a 1px line at the top of the view, but the line
also gets draw just above the NSSlider! logging shows the following
1) resize window - drawRect is called and the line above the slider
disappears
2) move slider - drawRect is called from my gradient view but with the
frame of the slider. The line then appears.
Is this a known issue with NSSlider and a custom view or have I missed
an idiosyncracy of NSControls.
Thanks in adavnce,
Jonathan
