[Pharo-project] [Spec] Expanding nodes programmatically
Hi, I built a TreeModel using Spec. I cannot find a way to expand the items in the model by using the left arrow on the keyboard. I cannot find neither the correct binding nor the correct message to call. Any hint here? Thanks in advance, R
I managed to accomplish the said behavior in this way
self on: (Character arrowRight asShortcut) do: [ :morph | | item | item := self selectedItem. morph selectedMorph toggleExpandedState. self updateTree. self selectedItem: item. ].
self is an instance of TreeModel. Is this the way it is supposed to be done? By the way Character arrowRight asShortcut does not always work: Sometimes it does not catch the event. And also the #selectedItem is not selected after expanding the node. Any intuition? Thanks in advance. Cheers, R On May 3, 2013, at 12:02 PM, roberto.minelli@usi.ch wrote:

Use the correct implementation of tree, it will help :) Ben On May 3, 2013, at 3:49 PM, "roberto.minelli@usi.ch" <roberto.minelli@usi.ch> wrote:

Ok, what's "the correct implementation of tree"? On May 3, 2013, at 4:48 PM, Benjamin <benjamin.vanryseghem.pharo@gmail.com> wrote:

It is AlainTreeModel. Ben told me, I cheated. When I don't know I go ask him. Reportedly he has sent a mail yesterday about that. But I didn't see it. 2013/5/3 roberto.minelli@usi.ch <roberto.minelli@usi.ch>

I'll look at AlainTreeModel, then. On May 3, 2013, at 5:35 PM, Clément Bera <bera.clement@gmail.com> wrote:

Me neither ;(
