Yes, but that will block the UI.

The progress bar update (world rendering) is done by force using ���self currentWorld displayWorld���, which also means that if the #do:displayingProgress: is forked there will be more than one UI rendering at the same time.

Open a window, evaluate the script below, drag and drop the window around.

[

Smalltalk allClasses 

do:[:aClass| (Delay forMilliseconds: 1) wait]

displayingProgress:[:aClass| 'Processing ', aClass name].

] fork

Best regards,

In the base image

Smalltalk allClasses 

do:[:aClass| (Delay forMilliseconds: 1) wait]

displayingProgress:[:aClass| 'Processing ', aClass name].

Hi all,

is there an easy was to do some thing that is constantly changing? so if my image freezes (to export a 1gb ston file for example) I can see when it���s done.    Or maybe there is a way to send a mac notification from Pharo?

Cheers.
