Desktop application with Pharo

Laurent,

I don't know that what I have done is better than anything else; the basic idea is adapted (aka shamelessly stolen<g> from a wiki entry.  Below is the class comment from something that I have successfully deployed as a "desktop app" using Pharo.  Using StandardWindow (thanks again to Pinesoft!!), it can #openInWorld (as part of the IDE) or #openFullScreen (when deployed), can be dragged only by the title bar, etc.

Is there a way to get an image to save a copy of itself and its change log in another folder?  Suppose the image is happily running in

   /home/me/Pharo-1.1.1/Pharo-dev-nnnn.image,changes
   /home/me/Pharo-1.1.1/Pharo-dev-nnnn.image,changes

and the goal is to do the steps below in

   /home/Software/CoolGizmo/programName.image
   /home/Software/CoolGizmo/programName.changes

Can the running image do that and continue to run in the Pharo-1.1.1 directory as though nothing happened?  That might make it possible to take the bumps out of the deployment process.

"To test in the IDE"
Equalize new asMorph openInWorld.


"To deploy - copy the image somewhere, and then do all of the following."
Preferences disable:#showWorldTaskbar.

10-09 - one-shot do-it to deploy Equalize; copy the image somewhere first!!"
Preferences disable:#showWorldTaskbar.
SystemWindow allSubInstances do:[ :each | each delete. ].


"Then do this as one do-it"
SmalltalkImage current snapshot: true andQuit: false.
Equalize new asMorph openFullscreen.

Subject: [Pharo-project] Desktop application with Pharo

I'm searching for a way to create desktop applications with Pharo (no multiple window).

Here's the current snippet that do what I want. Improvements / better code is really really welcome.

How I can change the title of the window ?


The snippet to evaluate in Workspace:

counter := Class new
              superclass: Object;
              addInstVarNamed: 'counter';
              compile: 'initialize
                           counter := 0';
              compile: 'counterString
                           ^ counter asString';
              compile: 'increment
                           counter := counter + 1.
                           self changed:#counterString';
              compile: 'decrement
                           counter := counter - 1.
                           self changed:#counterString';
              new.

panel := UITheme builder newPanel.
panel layoutPolicy: ProportionalLayout new.

panel
addMorph: (UITheme builder newLabelFor: counter getLabel: #counterString getEnabled: nil)
fullFrame:   (LayoutFrame fractions: (0@0 corner: 1@0.5)).
panel
addMorph: (UITheme builder newButtonFor: counter action: #increment label: '+' help: nil)
fullFrame:   (LayoutFrame fractions: (0@0.5 corner: 0.5@1)).
panel
addMorph: (UITheme builder newButtonFor: counter action: #decrement label: '-' help: nil)
fullFrame:   (LayoutFrame fractions: (0.5@0.5 corner: 1@1)).

World submorphs do: [:aMorph| aMorph delete].

World
layoutPolicy: ProportionalLayout new;
addMorph: panel fullFrame:  (LayoutFrame fractions: (0@0 corner: 1@1)).
