Extending an Existing GT Presentation

Administrator

Is there a mechanism for this? Say I want to add some actions to SequenceableCollection's Items presentation without overriding the existing method...

Also, is there a canonical documentation for GT? I found the blog posts, and the presentation documentation in the Moose book, but nothing about GT's hooks (e.g. my question above).

Thanks!

Cheers,
Sean

'Spot' for 'gtInspectorPresentationOrder' and inspect the Pragma, you get a free code browser to go with it

As a start, is that simple advice documented anywhere! But beyond that, while fine for me in the simplest case, is that a real answer for newbies?

Let me take a step back. The reason I want to do this is that I want to add context menu actions for items to generic presentations as seen in this screenshot:

The above is in a custom presentation. I want to add this same functionality to generic ones (e.g. SequenceableCollection)

Re: Extending an Existing GT Presentation

Hi Sean,

As of now, there is no option for extending one presentation. At the moment, you should create your own, and make it have a priority lower than the existing “Items" one. This will make your presentation appear first.

In the near future, we will also make all Inspector extensions toggle-able, like we did for the Spotter ones:
http://www.humane-assessment.com/blog/discovering-and-managing-spotter-extensions

Like this you will not have to override a method. You will create your own and disable the existing one.

Does this help?

Cheers,
Doru

I was hoping for a hook like
myGtItemsExtension: composite
<gtInspectorExtend: #gtInspectorItemsIn:>

But I guess disabling and delegating isn't that much worse:
myGtInspectorItemsIn: composite
...
^ (self gtInspectorItemsIn: composite)
selectionAct: ...;
yourself

Cheers,
Sean
