doesNotUnderstand:

Forward unknown messages to the target morph.
This is necessary since this morph is temporarily installed as the mouseFocus morph
in the hand.

addToRecognizerAndGiveChanceToEscape:
 

allowsMouseAction:target:

There are speciel genie gestures that allow to do a mouse action with a certain mouse button
pressed.
This method says wheter such a mouse action is possible
 

disableFocus
 

doMouseActionEvent:target:

There are speciel genie gestures that allow to do a mouse action with a certain mouse button
pressed.
This method does such a mouse action for the spcecified target
 

escapeFromRecognizer:
 

escapedDo:
 

giveChanceToEscape:
 

inverseTransformation:target:
 

modifiedMouseActionEvent:

There are speciel genie gestures that allow to do a mouse action with a certain mouse button
pressed.
This method returns the event for such a mouse action
 

modifiedStartEvent:

Modify the event according to the last gesture
 

preprocessGesture:

Preprocess the recognized gesture.
Return true if it should not be passed to the target morph, false otherwise
 

processGestureFeature:at:dictionary:startEvent:

Process a recognized gesture.
Generate CRGesture, do some preprocessing (if not permitted) and it to the target Morph
