NSResponderMBS.beginGestureWithEvent(e as NSEventMBS)

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
method	Cocoa	MBS MacBase Plugin	9.6	✅ Yes	❌ No	❌ No	✅ Yes	Desktop & iOS

Informs the receiver that the user has begun a touch gesture.

The event will be sent to the view under the touch in the key window.
Available in Mac OS X v10.6 and later.

NSResponderMBS.cancelOperation

Type	Topic	Plugin	Version	macOS	Windows	Linux	iOS	Targets
method	Cocoa	MBS MacBase Plugin	8.4	✅ Yes	❌ No	❌ No	✅ Yes	Desktop & iOS

Implemented by subclasses to cancel the current operation.

This method is bound to the Escape and Command-. (period) keys. The key window first searches the view hierarchy for a view whose key equivalent is Escape or Command-., whichever was entered. If none of these views handles the key equivalent, the window sends a default action message of cancelOperation: to the first responder and from there the message travels up the responder chain.

If no responder in the responder chain implements cancelOperation:, the key window searches the view hierarchy for a view whose key equivalent is Escape (note that this may be redundant if the original key equivalent was Escape). If no such responder is found, then a cancel: action message is sent to the first responder in the responder chain that implements it.

NSResponder declares but does not implement this method.

method	Cocoa	MBS MacBase Plugin	8.4	✅ Yes	❌ No	❌ No	✅ Yes	Desktop & iOS

Informs the receiver that the mouse cursor has moved into a cursor rectangle.

Override this method to set the cursor image. The default implementation uses cursor rectangles, if cursor rectangles are currently valid. If they are not, it calls super to send the message up the responder chain.

If the responder implements this method, but decides not to handle a particular event, it should invoke the superclass implementation of this method.
