Hello, I'm displaying a TreeStore in a TreeView and I want to allow the user to re-organize its data by drag-n-dropping.
( If you want to try, the code is available with "bzr branch lp:gtg" in taskbrowser/browser.py. I will specify the line. If I give you a given rev. number $X, type, after branching, "bzr revert -r $X" use "./debug.sh" to launch the soft with a dummy data set ) In order to handle drag-n-drop, I connect to the row-changed and row-deleted signal to the function that will update my datas to reflect the change (rev.123,li 675) It was working fine until my co-coder fixed some sorting bugs (typically, we display strings but we want to sort them as integer or date). Between rev. 108 and rev. 109, drag-n-dropping stopped working. The tree just refuses you to drag-n-drop. I've looked and found that commenting one line added during this commit was causing the problem : self.treestore.set_sort_column_id (2, gtk.SORT_ASCENDING (rev.109,li 113) Commenting this line restore drag-n-drop. Re-enabling it break the feature. So, why such a behaviour ? I'm sure there's something I don't understand about drag-n-drop and sorting. Can anyone explain to me how I can keep this line and restore drag-n-drop functionnality ? Thanks in advance, Lionel PS: in rev.123 this line is now in taskbrowser/treetools.py, li 19
