How do I get the selection in a Glamour tree?
 
|
I'm trying to set some actions on items in a glamour tree presentation, say:
actions: [:tree | tree selection xMenuItems ] But #selection called on the widget returns nil. Is this the expected behaviour? I managed to get what I wanted after diving in the object: actions: [:tree | tree selectionPath last xMenuItems ] -- Simon _______________________________________________ Moose-dev mailing list [hidden email] https://www.iam.unibe.ch/mailman/listinfo/moose-dev |

I cannot reproduce this problem :).
Are you sure that you selected the item before hand? In any case, take a look at the code examples from MooseBrowsers. For example: MooseBrowsers>>navigationBrowserOn: scopeSelector ... actions: [ :tree | tree selection mooseInterestingEntity mooseFinderActions ] Cheers, Doru On Thu, May 27, 2010 at 11:35 AM, Simon Denier <[hidden email]> wrote: I'm trying to set some actions on items in a glamour tree presentation, say: _______________________________________________ Moose-dev mailing list [hidden email] https://www.iam.unibe.ch/mailman/listinfo/moose-dev |

But I can't find a simple example to reproduce the case. If you are really motivated, I can explain how to reproduce in my current example.

Yes, I am interested. I never encountered this case. "tree selection"
gets the result from the #selection port. Please describe the scenario.

Ahh, the problem is that you also specify the #send: clause, which is
a post transformation that affects the value of the #selection port. Given that sometimes this value is nil, you get nil :).

Given that sometimes this value is nil, you get nil :). Funnily, it's also what issue http://code.google.com/p/moose-technology/issues/detail?id=390 is about. I don't know how I came to this conclusion in the first place.
