Hello dear GTG contributors, Here's the status of my current big refactorisation : https://code.edge.launchpad.net/~gtg/gtg/gtg-refactor
I've discoverd that GTK is even worse than what I thought : it's hard to understand to make basic stuffs and it's nearly impossible to make more-or-less complicated stuffs. In our case, I wanted to use gtk.TreeModelFilter to implement workview/tagview/… It's not possible. TreeModelFilter cannot display a node if the parent is hidden. Point. This is not in the documentation but it is. As a consequence, I've started my own FilteredTree which is not related to gtk but is a View layer above our own Tree. This filteredTree is given to the gtk.TreeModel as an argument. I've also started a FiltersBank who will store all of our filters so that they are in one place. There's one main FilteredTree that you can get through the requester. This main FilteredTree does use the filters applied throught the requester. This allow plugin writers to easily get the current displayed tree (main View). For custom views, the plugin writers are able to get their own FilteredTree and apply on it the filters they want. (this is not finished yet but in good shape). I hope this will help plugin writers and make our requester API saner. Currently, there's only one filter implemented : workview (and it's not complete. It currently only check if the node if a leaf node or not). Also, FilteredTree is currently completely suboptimal from a performance POV. This is not a big deal because I foresee plenty of low-hanging fruit to improve the speed. BUGS **** For whatever reason, when I apply a filter, the treeview is not well refreshed. I don't undestand really what is happening. - If you start in normal mode then apply the workview, the workview tasks are added but others stay. Unapplying workview does nothing. - If you start in workview the unapply it, nothin happens. If you re-apply it, nothing happens. Help on this particular bug would be highly appreciated. TODO ***** - implement the filters : workview, tags(which will be a special case), active, closed, … : this is trivial to do in FiltersBank.py - make use of the filters in the browser (closed_pane will be implemented with a different FileredTree) : this will not be hard. - make the difference between the main View and custom FilteredTrees. I know how to do it ;-) - unit tests for FilteredTree. Any help on this is welcome. WHAT WILL BREAK ************** Because requester was heavily changed, the following will break : - all plugins - dbuswrapper Also, what I've intentionnaly broken : - drag-n-drop (code commented in tasktree.py, need to be adapted) - multi-parent support (need to be tested once everything else is working) - tag_count (code commented out in tagtree.py because of change in the requester) Any feedback is welcome (specially on my current Treeview refresh bug) Lionel _______________________________________________ Mailing list: https://launchpad.net/~gtg-contributors Post to : [email protected] Unsubscribe : https://launchpad.net/~gtg-contributors More help : https://help.launchpad.net/ListHelp
