[Moose-dev] Re: Issue 1099 in moose-technology: update visible list items on selection

Comment #2 on issue 1099 by usman.bh...(a)gmail.com: update visible list items on selection https://code.google.com/p/moose-technology/issues/detail?id=1099 As per my understanding, PaginatedMorphTreeMorph can have two modes of expansion: incremental mode or scroll to the page of selected element(s). Incremental mode expands the list up to the selected item. Paged mode shows a fixed number of elements on each page and jump to a specific page item selected. To see it working, execute script below: | treeMorph aWindow aModel | aModel := PaginatedMorphTreeModel new rootItems: (1 to: 100) asArray. aWindow := aModel theme newWindowIn: World for: aModel title: 'test'. treeMorph := aModel defaultTreeMorph. treeMorph pageSize: 30. treeMorph buildContents. aWindow addMorph: treeMorph fullFrame: (LayoutFrame fractions: (0 @ 0 corner: 1 @ 1) offsets: (0 @ 0 corner: 0 @ 0)). aWindow open. aModel expandItemPath: {50}. Glamour chooses the incremental mode and effectively this mode is not adapted for 100K items. In my opinion, we should use paged mode and it should not require drastic changes to the current tree model in Glamour. As for the bug, the solution will be that the model needs to do expandItemPath: when a selection is made and update list. And I should provide a fix once we find an agreement on the selection display mode. -- You received this message because this project is configured to send all issue notifications to this address.
