You need the aio vm plugin. But OSProcess works without. Should be with the new vms.

Re: [Pharo-users] GTInspector: editable custom presentation?

Use #column:evaluated:modified: Regarding documentation, if you inspect the class GTInspector you will get a presentation showing all custom presentation from the image.

Hi all! I get this strange error when executing some tests. What is it? I think It has something to do with OSProcess. I will be happy to give more information if needed. Thanks!

Re: [Pharo-users] accessing themed colors from morph

Thank's for the pointers. It seems to me that they access it via 'self theme'; in any case my problem is, for the moment, solved.

GTInspector: editable custom presentation?

by Johan Fabry

Hi all, Iâm trying to make a custom GT Inspector presentation for a variable store (i.e. something like a dictionary). The code I have right now shows me the data I want: gtInspectorDetailsIn: composite <gtInspectorPresentationOrder: 0> composite table title: 'Details'; display: [ self allVariables ]; column: 'Variable' evaluated: #key; column: 'Value' evaluated: #value; send: #value But, what I would like to do is to take advantage of the edit ability of the inspector to change what is displayed in the Value column and save this directly to the store. I have the method for that (setVariable: withValue: ) but I cannot find how to tell the GTInspector to add the edit functionality and to call this method when an edit action is made. How should I do this? This is Pharo 4.0 BTW. PS: I was very impressed with the customizability of the GT inspector â¦ until I wanted to make my own presentation and I found almost no documentation on how to do it. For such a major feature I thought there would be HOWTOâs easily found online but there are none. Not in the GT toolkit page http://gt.moosetechnology.org/ and the pages it points to, nor in the various blogs that talk about the GT Inspector. I did find a starting point on how to do it, but no clear information. Did I overlook something? If so, I think it would be better that this info is more easily found. ---> Save our in-boxes! http://emailcharter.org <--- Johan Fabry - http://pleiad.cl/~jfabry PLEIAD lab - Computer Science Department (DCC) - University of Chile

A button has a theme dependent color, that may depend on the type and state (enabled/disabled) of the button. A list morph may have different colors for even and odd index, selected, enabled, disabled ... A label model font/color may depend on its use (window title/menu title/ button label ...).

accessing themed colors from morph

by Peter UhnÃ¡k

Hi, how is set the background color of a morph? I could access directly "Smalltalk ui theme backgroundColor" from within the Morph, but I don't see anywhere that something is using themed colors this way. So I assume there is some other way; what am I missing? Note that I don't want to use the color for background of the morph but I need to make a decision based on the color in the morph. Thanks, Peter

Re: [Pharo-users] When to use Versionner and when to use Monticello

by Sean P. DeNigris

Sergio Fedi wrote > When do we use Versionner and when do we use Monticello? Simple answer: Monticello is our SCM system that groups code into packages. Metacello is a package management system that declares dependencies between those packages in configuration classes. Versionner is a GUI for Metacello that allows you to use a nice (but limited, as are most GUI tools) tool instead of writing configs by hand. ----- Cheers, Sean -- View this message in context: http://forum.world.st/When-to-use-Versionner-and-when-to-use-Monticello-tp4… Sent from the Pharo Smalltalk Users mailing list archive at Nabble.com.
