Refresh problem with right aligned rectangle while resizing anNSOutlineView
-
Hello guys,
I would to place a simple round rectangle (as Mail.app unread badge) at the
right side of an NSOutlineView.
So this is the code I've used to get an NSBezierPath to draw (
http://developer.apple.com/samplecode/Reducer/listing21.html)
while this is the portions of code inside drawInRect event that draw it.
NSBezierPath *roundRect = [NSBezierPath bezierPathWithRoundedRect:
NSMakeRect(NSWidth(cellFrame)-20,inset.origin.y,20,20) cornerRadius: 4.0];
[controlView lockFocus];
[roundRect stroke];
[roundRect fill];
[controlView unlockFocus];
All works fine but when I try to resize the outlinew view the old rectangle
position still visible with the new one
(look here: http://img66.imageshack.us/img66/7857/picture4cf2.png)
the problem does not append if i try to put an NSImage using
compositeToPoint...
Why? Where the code is wrong?
Thanks -
Yes the highlight color has been replaced with my own. In fact I've used a
modified version of Source LIst (you can found it here:
http://web.mac.com/leemorgan/Bit_Bucket/Source_Code.html or
http://www.latenightsw.com/blog/?p=45) and I've added only the code I've
pasted before. I'm on leopard (if you want I can send a link to the complete
source).

Since you are on Leopard, use the built in source list highlighting
(assuming you are linking against 10.5).

Hello Corbin,
I've tried to remove the highlightSelectionInClipRect and the hightlight
effect but nothing has changed so I'm not sure about the origin of this
refresh problem. This is the code, compile yourself and try to resize the
window itself (the rectangle is red, just a test).
