Omnibrowser help

Are there some tips/documentation somewhere on getting the most out of the OmniBrowser? The MulitpleSelection browser looks interesting (sort of like the tabbed browser in VisualWorks), but I don't quite understand its behaviour and what method it decides to show in which pane when you move around or save changes.

On the same topic, can anyone point me toward how I could add a new item to the class context menu in the OmniBrowser? I want to add a new template selection menu item (like "new class template" and "new trait template") because I have created a method that creates TWO classes at the same time for an Aida application (A domain model class AND its associated WebApp class).

Thanks,

Rob Rothwell

I suggest to have a look at this paper, it is dedicated to user and developers of
OmniBrowser:
http://www.iam.unibe.ch/~scg/Archive/Papers/Berg07cOmnibrowser.pdf

I'm actually right now working on a documentation for this browser, it should be
finished soon.

First, create a subclass of OBCommand. Then you need to implement at least the
methods #execute, #label and #isActive (have a look at eg. OBCmdNewClassTemplate).
Finally, you can add a method called eg. 'cmdAIDATemplate' to OBCodeBrowser or a
subclass of it. It is important that this method starts with 'cmd'. When you then
start a new system browser, the command should be available (if #isActive answers
true for the selected class).

Thanks...some "light reading" for a Sunday afternoon! How hard do you think it would be to use the OmniBrowser model to hook up to non-morphic views? I am exploring the idea of a web-based design layout tool for web development (using Aida), and the next logical step is to create a browser in a prototype-ui window or something that would let you wire your model to the design on the page.

I'm actually right now working on a documentation for this browser, it should be
finished soon.

You know, this is a great time to be new to Squeak. There is an awful lot of good work going on out there. I always thought I was a decent programmer, just not world class! But, as in the example above, much of the "heavy lifting" has been done already, and the problem I describe may be just hard enough to be interesting to me, but actually doable thanks to the work of others!

First, create a subclass of OBCommand. Then you need to implement at least the
methods #execute, #label and #isActive (have a look at eg. OBCmdNewClassTemplate).
Finally, you can add a method called eg. 'cmdAIDATemplate' to OBCodeBrowser or a

true for the selected class).

Thanks for this. It seems very modular and easy to extend (based on your description)! I'll give it a shot!

Thank you both.

In the Squeak Universe, it always seems best to ask before you start. Someone else has usually been there first... !

When I do this, I get TWO menu items, and if no class is selected in the class pane, I get one all by itself. I just copied the normal new class template code to execute as follows:

'From Squeak3.9.1 of 2 March 2008 [latest update: #7075] on 18 March 2008 at 3:58:54 pm'!

OBCommand subclass: #OBCmdNewWebAppTemplate

instanceVariableNames: ''

classVariableNames: ''

poolDictionaries: ''

category: 'WebAppBuilder'!

!OBCmdNewWebAppTemplate methodsFor: 'as yet unclassified' stamp: 'rjriv 3/18/2008 15:58'!

execute

| class definition |

class := target theNonMetaClass.

definition := (OBClassDefinition

environment: class environment

template: (Class template: class category)).

requestor announce: (OBDefinitionChanged definition: definition)! !

!OBCmdNewWebAppTemplate methodsFor: 'as yet unclassified' stamp: 'rjriv 3/18/2008 15:43'!

isActive

^true.! !

!OBCmdNewWebAppTemplate methodsFor: 'as yet unclassified' stamp: 'rjriv 3/18/2008 15:36'!

label

^ 'new web app template'! !

Change this to read:

isActive
^(target isKindOf: OBClassNode) and: [requestor isSelected: target]

Thanks. That's why I'm still asking beginner questions...I don't know why my brain didn't even go check that method out. I think I was just thinking "of course I want it to be active!"

I have now put this documentation online:
http://scg.iam.unibe.ch/Research/Hermion
(see in particular the wiki page linked).

If you still have any questions after reading this documentation, just
tell me, then I will extend the doc.

Thanks again...the multiple pane browser makes a lot more sense now!

Now I am interested in Hermion...

David, if you're still on the list - thank you! Three years later, this post saved my day :)
