Pharo Issue Tracker - Manuscript (Case [Issue]22648) Morphic - spaced double-click misinterpreted as start drag event

Manuscript Notification

	Ivo Roefs opened Case 22648: spaced double-click misinterpreted as start drag event and assigned it to Everyone: Bug in Morphic: 1. Pharo Image • You are subscribed to this case

I first observed this problem in Nautulus by quickly subsequently clicking on two different methods, which results in a drag action of the first clicked method.

This behaviour is initiated in MouseClickState>>handleEvent: evt from: aHand

This problem can be resolved by removing "self drag: firstClickDown" under the branch clickState == #secondClickDown.

I cannot imagine that a second click can ever be the start of drag event?

Stephan Eggermont's reply in discord:

There doesn't seem to be enough test coverage there, and the behaviour seems incorrect. It is also present in Pharo 7

The method is too long , and the class is in the wrong place

I'd guess Morphic-Base-Events would be a better place
