I've been having a fair few issues with NSBezier boxes lately (a.k.a
boxes with rounded corners)
I've created a NSView subclass that contains the following code,
then threw a few on a window with some controls over the top:
- ( void ) drawRect: ( NSRect ) rect
{
NSBezierPath* thePath = [NSBezierPath bezierPath];
[thePath appendBezierPathWithRoundedRect:rect xRadius:10.0
yRadius:10.0];
Change the line above to:
[thePath appendBezierPathWithRoundedRect:[self bounds] xRadius:10.0
yRadius:10.0];
and you should get what you want, although it would still be less than
ideal code.
Any ideas?
Several things. First, the rectangle you get as a parameter to -
drawRect: is often smaller than the view recieving the message. The
rect is given so that you don't have to draw the entire view every
time. (See also -needsToDrawRect:, if you want to optimize this.)
Second, figure out your drawing geometry in -setFrame:, not in -
drawRect:. -drawRect: itself should be as little code as possible,
because it can be invoked at any time.
