Sorry to answer so late. I was having few days off. I am now up and running :-) > Now that I've managed to use Pharo at work (youhou !!) I'm in a case where I have very long tests (selenium acceptance tests) *and* I want them to run.

But in OB that should be easy. You can add, remove and change any command without the need for an override. The only exception is the code pane which gets its is commands from the Paragraph editor.

[Pharo-project] NullTextStyler

by StÃ©phane Ducasse

Hi fernando benjamin did a NullTextStyler. I did a pass but I'm not sure this is good :) Gofer new squeaksource: 'PharoTaskForces'; package: 'RecentSubmissions'; load. Could you have a look at it and I would like to push it in the image because I think that this is a nice infrastructural class to have. Stef

Re: [Pharo-project] Early days of an MVP framework

by Gary Chambers

Rather than use ComposableMorph directly you will be better off just using it to build the morphs you need. A PanelMorph will pass on #enabled: to its submorphs, rows and columns are made from PanelMorphs too. An example: |row| row := UITheme builder newRow: { UITheme builder newCheckboxFor: nil getSelected: nil setSelected: nil label: 'Checkbox in a panel' help: nil. UITheme builder newButtonFor: nil action: nil label: 'Button in panel' help: nil}. row vResizing: #spaceFill; listCentering: #center; wrapCentering: #center. ((UITheme builder newColumn: { row. UITheme builder newRow: { (UITheme builder newButtonFor: row action: #enabled: label: 'Enable panel' help: nil) arguments: {true}. (UITheme builder newButtonFor: row action: #enabled: label: 'Disable panel' help: nil) arguments: {false}}}) extent: 300@100; openInWindow) setLabel: 'Panel Enablement' Regards, Gary ----- Original Message ----- From: "Schwab,Wilhelm K" <bschwab(a)anest.ufl.edu> To: <Pharo-project(a)lists.gforge.inria.fr> Sent: Tuesday, August 10, 2010 5:19 AM Subject: Re: [Pharo-project] Early days of an MVP framework > Gary, > > Is there a way to disable a ComposableMorph and all of its children? > > Bill > > > > > ________________________________________ > From: pharo-project-bounces(a)lists.gforge.inria.fr > [pharo-project-bounces(a)lists.gforge.inria.fr] On Behalf Of Schwab,Wilhelm > K [bschwab(a)anest.ufl.edu] > Sent: Monday, August 09, 2010 10:38 PM > To: Pharo-project(a)lists.gforge.inria.fr > Subject: Re: [Pharo-project] Early days of an MVP framework > > Gary, > > I have a composite GUI that appears to work.
