我有下面的子类 NSWindow 代码,有一个可以缩放的动画视图,我想在正确的位置单击它时接受单击,如果它在外部则拒绝(单击)。
下面的代码运行良好,只是窗口不允许点击通过。
- (void)mouseDragged:(NSEvent *)theEvent {
if (allowDrag) {
NSRect screenVisibleFrame = [[NSScreen mainScreen] visibleFrame];
NSRect windowFrame = [self frame];
NSPoint newOrigin = windowFrame.origin;
// Get the mouse location in window coordinates.
NSPoint currentLocation = [theEvent locationInWindow];
// Update the origin with the difference between the new mouse location and the old mouse location.
newOrigin.x += (currentLocation.x - initialMouseLocation.x);
newOrigin.y += (currentLocation.y - initialMouseLocation.y);
if ((newOrigin.y + windowFrame.size.height) > (screenVisibleFrame.origin.y + screenVisibleFrame.size.height)) {
newOrigin.y = screenVisibleFrame.origin.y + (screenVisibleFrame.size.height - windowFrame.size.height);
}
// Move the window to the new location
[self setFrameOrigin:newOrigin];
}
}
- (void)mouseDown:(NSEvent *)theEvent
{
screenResolution = [[NSScreen mainScreen] frame];
initialMouseLocation = [theEvent locationInWindow];
float scale = [[NSUserDefaults standardUserDefaults] floatForKey:@"widgetScale"]/100;
float pX = initialMouseLocation.x;
float pY = initialMouseLocation.y;
float fX = self.frame.size.width;
float fY = self.frame.size.height;
if (pX>(fX-fX*scale)/2 && pX<(fX+fX*scale)/2 && pY>(fY+fY*scale)/2) {
allowDrag = YES;
} else {
allowDrag = NO;
}
}
