Exit loop

Hello All,

I am trying to create a button or morph that when pressed stores the present Squeak image and exits Squeak. I have tried both with a PluggableButtonMorph with its action associated and with a plain rectangleMorph defining its mouseDown method as follows:

mouseDown: anEvent
SmalltalkImage current saveImageInFileNamed: (SmalltalkImage current imageName).
Smalltalk quitPrimitive.

In both cases pressing the morph performs as expected, but when I try to launch that image back and the application with it, it seems to be looped into that event again exiting immediately.

I know I am missing something important. Could someone explain me what it is ?

Thanks very much in advance.

This works for me:

TheWorldMenu new saveAndQuit

But if you want to go one level lower, you could use this:

SmalltalkImage current snapshot: true andQuit: true

Hope this helps!

Sure. "Saving" an image means simply to stop time. So time stops
"inside" of #saveImageInFileNamed:, and when you resume the image,
the first thing it executes is ... quitPrimitive. That's why we have
that method that does both: #snapshot:andQuit:.
