We have a hierarchy, displayed in an NSOutlineView. We also allow the user to specify the root at any of the top two levels. When moving the root down the tree, if there is no selection, the new root is the first element of the top-level tree. If rows are selected, we use the first index path to determine the new root. Going back up, we load the higher-level root and select the item that we moved up from. This all works. However, it would be nice if we had a couple of additional disclosure options available. One option would be to keep selected paths selected and disclosed when moving between root levels. Another option would be to keep ALL relevant disclosures disclosed when changing root levels. Is there any way to do this?
There appears to be a means (a check box in IB) to save disclosure paths for restoration when reopening a document. So that info must be available somewhere, although apparently not available to the developer. Other than building a storable disclosure tree and using it (appropriately modified) to (laboriously) re-disclose paths, is there a better way? _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
