I have an NSBrowser and try to use setRowHeight, but I get the error:
"setRowHeight: is not supported for browsers with matrix delegates."
I really don't understand what this means, and if someone could help me out by either telling me how to fix it or even just what a matrix delegate is, it would be much appreciated.
A delegate is a helper object that you tell the
NSBrowser instance about either by using
-setDelegate: in code or hooking the delegate outlet up in IB (the NIB editor). It is commonly used to fill the browser's data, determine programmatically the layout options, etc.
If you have a delegate assigned in your NSBrowser instance, you are expected (required) to give the row height using the delegate method:
- (CGFloat)browser:(NSBrowser *)browser heightOfRow:(NSInteger)row inColumn:(NSInteger)columnIndex
Which will allow you to optionally set the row height on a per-row basis, but in your case, you can safely return a constant.
