Convert NSPoint in screen coordinates to window coordinates
cocoa, drag-and-drop
Solution
Have a look at the NSWindow documentation, there is a
- (NSPoint)convertScreenToBase:(NSPoint)aPoint
which will let you convert the point to window coordinates.
Problem
I am implementing drag and drop in a cocoa application and I am using the following method from the NSDraggingSource Protocol: ``` - (void)draggedImage:(NSImage *)draggedImage movedTo:(NSPoint)screenPoint{ ``` The NSPoint is given in screen coordinates and I need it in window or view coordinates. If the method was called with an NSEvent I could do the following: ``` -(void)mouseDown:(NSEvent *)pTheEvent { NSPoint tvarMouseInWindow = [pTheEvent locationInWindow]; NSPoint tvarMouseInView = [self convertPoint:tvarMouseInWindow fromView:nil]; } ``` But I cannot figure out how to do it with just an NSPoint. Thanks in advance!
