Jim,
From your code snippets, it doesn't look like you have subclassed
NSView, you will need to do this before you can do custom drawing in an
NSView.
Once you have subclassed the view, you need to override the drawRect
method with something like this...
public void drawRect(NSRect rect) {
NSRect nr = new NSRect(0,0,40,40);
NSBezierPath BP = NSBezierPath.bezierPath();
NSColor.colorWithCalibratedRGB(1f, 0f, 0f, 0.5f).set();
BP.fillRect(nr);
}
This will draw a transparent red rectangle in your view.
Let me know if you need any more info.
Cheers
Moray
In IB, I have created a window with a NSview, and have called it
myview:
public NSView myview;
Now, how do I draw a simple rectangle using NSRect to this NSview?
I hoped that something like...
nr = new NSrect(0,0,40,40);
myview.drawRect(nr);
...would do it, but no. It compiles without error or warning -- yet
does nothing. What is the proper way to draw to a NSView?
Jim
