Cocoa: change cursor when it's over an NSButton

Question

How can I change the cursor when it's over an NSButton?

Answer 1

You should subclass NSButton first, then add the code below.

- (void)resetCursorRects
{
    if (self.cursor) {
        [self addCursorRect:[self bounds] cursor: self.cursor];
    } else {
        [super resetCursorRects];
    }
}

Now you can set cursor as you like.

[self.button setCursor:[NSCursor pointingHandCursor]];

Note: add cursor as a property of your subclass, like this:

@property (strong) NSCursor *cursor;
