Hi all,I have a background application and now want to change cursor image over
different types of views. I create a NSTrackingArea with option
(NSTrackingCursorUpdate | NSTrackingActiveAlways) and add the tracking area to
my customer view. Also, I rewrite the -(void)cursorUpdate:(NSEvent *)event
method and set the cursor image there. However, when I run this background app,
I find the cursorUpdate method is called(judging from the log info) but the
cursor image isn't been updated. Does anyone have experience about it? Did I
miss anything? Here is my code:#import "ContentView.h"
@implementation ContentView
- (id)initWithFrame:(NSRect)frame {
self = [super initWithFrame:frame];
if (self) {
trackingArea = [[NSTrackingArea alloc] initWithRect:[self bounds]
options: (NSTrackingCursorUpdate |
NSTrackingActiveAlways)
owner:self userInfo:nil];
[self addTrackingArea:trackingArea];
}
return self;
}
- (void)cursorUpdate:(NSEvent *)event {
NSLog(@"cursorUpdate");
[[NSCursor crosshairCursor] set];
}Thanks in advance !
