Re: [Pharo-users] Multi desktops inside Pharo!

by Torsten Bergmann

Hi Julien, what I remember from history - Jochen F. Rick had a "JRWorldManager" implemented back in 2010 - was discusssed here http://forum.world.st/Multiple-Worlds-was-Re-Can-I-use-Projects-in-Pharo-td… - code is here http://forum.world.st/attachment/2242195/0/JRWorldManager.st (basically something to manage the desktops) - then Sean picked up the idea in 2011 and implemented - blog post http://seandenigris.com/blog/?p=767 - he provided "MultipleWorlds.2.cs" which I think is lost during bugtracker transition - later default Pharo image was reworked for the world to have WorldMorph instances instead of Squeaks PasteUpMorph, so the code of Sean and Jochen would be obsolete anyway Some tips: ========== - Pharo has a global called "World" which is pointing to the current world of displayed morphs, you need to switch this and handle/manage new Worlds = Desktops. - in older Pharo versions and Squeak this was a PasteUpMorph, now it is an instance of class "WorldMorph" - note that there is a class side method "installNewWorld" with the nice comment "let us play God." - basically you already have the parts with a DeskopManager and the switch via keyboard, you just need to play with #installNewWorld and #install method of the worlds Note: check the comments of the class and methods in WorldMorph - this might be subject to change - to get a thumbnail form of the world you can use: |sizeFactor| sizeFactor := 0.3. World taskThumbnailOfSize: (Display width * sizeFactor) @ (Display height * sizeFactor) - see how the preview is handled in TaskListMorph newPreviewMorph/updatePreview methods to get an idea So all the pieces of the puzzle are there - just connect them correctly. Side Note: default Pharo image has the possibility to put an external picture somewhere that is used by the theme as the background image. Cant remember where it is - just browser for "background..." methods in the Finder. With multiple desktops I guess this needs some love as well to have a backgorund per desktop. Hope that helps!

Ok, personally I would like to help to provide an utility to manage desktops under Pharo but if there are things I can reuse or get inspired I want to know them! :) Julien

Multi desktops inside Pharo!

by Torsten Bergmann

Julien Delplanque wrote: >I created a small utility that make possible to have multi desktops: >https://github.com/juliendelplanque/desktopsmanager. Your code works for me in Pharo 5, havent tried in Pharo 4. Unfortunately it does only work for Pharo "windows" but not general morphs. If you evaluate ElipseMorph new openInWorld and hit CTRL+SHIFT+J you will see that the morph stays on the desktop. So your goodie is a "window switcher" and not a "desktop switcher". I guess it would be better if you would really switch the WorldMorph instance referenced by the global "World" variable. There already was a solutions once discussed/contributed with code here http://forum.world.st/Multiple-Worlds-for-Pharo-stable-td3233552.html http://seandenigris.com/blog/?p=767 I think it got lost in the old bugtracker. Maybe Sean (who wrote it) can help here, update the code and merge with yours. Ideally such a "Switch desktop" possibility would be part of the standard Pharo 5 image including a small preview of the whole desktop similar to what usual operating system window manager do and the possibility to provide different backgrounds to the desktops. Thanks Torsten

Re: [Pharo-users] Multi desktops inside Pharo!

Yes it should work on Pharo 4. Did you opened windows as said in the README's notes section? If you have no window opened in a desktop you cant create a new desktop. If you did, can you try: DesktopsManager uniqueInstance nextDesktop and DesktopsManager uniqueInstance previousDesktop Do you see the DesktopMorph on bottom right of the screen?

It does not work for me. Should it work in Pharo 4.0?
