I have class Canvas
and another custom view CanvasItem
both subclasses of NSView
. The CanvasItem
has a IKImageView
subview.
Canvas
overrides magnifyWithEvent
to react to the gesture. Everything works fine except the case when the gesture is done on one of the CanvasItem
s then the IKImageView
handles the event and zooms the image instead of passing it up the view hierarchy. Is here a way to prevent IKImageView
from handling gestures?
I tried setting editable
to false
but with no effect.
Found a solution that works for me. In the end it was quite simple: I created a new subclass of IKImageView
overwrote the magnifyWithEvent
and passed the event to the next responder. And then used this class instead of the original IKImageView
.
class MyIKImageView : IKImageView {
override func magnifyWithEvent(event: NSEvent) {
self.nextResponder?.magnifyWithEvent(event)
}
}
