Using TreeModel>>selectAll
Hi, I'm not sure how this method should be used. I tried in different ways, for example: TreeModel new roots: #(1 2 3); selectAll; openWithSpec But always the items are unselected. Is it a bug? or I didn't find the way to use it? Thanks, MartÃn
your tree here is single selection so it will not work TreeModel new roots: #(1 2 3); multiSelection: true; openWithSpec; selectAll Ben On 05 Dec 2013, at 15:38, Martin Dias <tinchodias@gmail.com> wrote:

ouch! thanks Ben. Another related question: is there any way of selecting an arbitrary item? I tried (among others) with: TreeModel new roots: #(1 2 3); multiSelection: true; openWithSpec; selection: 3 without success.

Hi, I'm back with more annoying questions :) Using #whenSelectedItemsChanged:, I see that the block is evaluated a lot of times: log := OrderedCollection new. roots := #(1 2) collect: [ :each | TreeNodeModel new content: each; selected: true; yourself ]. TreeModel new roots: roots; multiSelection: true; whenSelectedItemsChanged: [ :items | log add: items ]; openWithSpec. log ---> an OrderedCollection(#() an OrderedCollection(1) an OrderedCollection(1) an OrderedCollection(1 2) an OrderedCollection(1 2) an OrderedCollection(1 2)) I'd expect only one evaluation... is it a bug or a feature? cheers, MartÃn On Sun, Dec 8, 2013 at 12:22 AM, Martin Dias <tinchodias@gmail.com> wrote:

One thing I didn't understand is, are valueholders supposed to announce changes, even if the "value" didn't changed? |log node | log := OrderedCollection new. node:= TreeNodeModel new content: $a; whenSelectedChanged:[:item | self halt.log add:item]; selected: true; selected: true; selected: true. log will log three times, even the value (selected=true) didn't changed at all. (or at most one if "selected" is initialized with false). Nicolai 2013/12/9 Martin Dias <tinchodias@gmail.com>
