[gwt-contrib] Re: gen2 TreeTable demo online
Hi, try it like this: 1. Collapse the tree (=close all tree nodes with the button in the left bottom corner) 2. enter value inti iq-filter 3. select operator (=, !=, , etc.) In tree view the filter applies only to the root elements. If you want to filter all items switch to table view. Hope this helps, Daniel On 25 Nov., 14:57, ANDRES BRUN [EMAIL PROTECTED] wrote: Hi Daniel I was testing the filters but, IQ Don't works, I put it on the field, the 117 number and nothing happened, all fields are blanking. how works?

[gwt-contrib] Re: gen2 TreeTable demo online
I've been following this patch because the app I'm working on will really benefit from it. Ideally, I do not want children to fall off the list to the next page. My table will start with all children collapsed. When the user opens a node, I would like for new rows to show up on the table. My table will already have a vertical scroll bar, so I'd like the nodes below to just scroll down a bit. I don't want to move what pages in the table items appear on because of opening/closing of nodes. Not all use-cases will be like this, but that is what would be best for my app. Maybe a setting could be added to define the paging behavior when nodes are opened? Daniel - great work on this patch. I'm very excited to pull it into my project! Thanks! -Brad On Nov 25, 7:10 am, Bruce Johnson [EMAIL PROTECTED] wrote: Looks cool, Daniel. I do have a question about its basic usability, though.

[gwt-contrib] Re: gen2 TreeTable demo online
Setting the page size dynamically might be the best solution for my situation. I have lots of top-level nodes (thousands) and some of them... maybe 5% will have 2-8 children nodes. Nodes are never more than 1 child deep. I need paging, but don't want to adjust what page an item is on due to opening or closing nodes. I will look into setting the page size dynamically... Daniel, please let me know if you get a chance to test this and how it goes. Thanks! -Brad On Nov 25, 7:43 am, dflorey [EMAIL PROTECTED] wrote: Another option would be to set the page size dynamically to the number of visible children of the opened root node. I'll give it a try and see if it makes navigation more intuitive. If you end up with many many child nodes you'll see that paging is not the worst possible solution (as rendering times will not esceed a certain level) ;-) On 25 Nov., 14:34, Brad Larson [EMAIL PROTECTED] wrote: I've been following this patch because the app I'm working on will really benefit from it.

[gwt-contrib] Re: gen2 TreeTable demo online
Yep, this seems to be a good idea! I'll add this as an option to the tree. As I still would like to keep the number of items per page limited I'd propse to present the child when expanded like this (pagesize=5): - Numbers - Integers ... - ...more (click to collapse) - 56 - 57 - 58 - ...more On 25 Nov., 15:57, Bruce Johnson [EMAIL PROTECTED] wrote: On Tue, Nov 25, 2008 at 8:33 AM, dflorey [EMAIL PROTECTED] wrote: Hi Bruce, have you seen that you can easily navigate to the parent node by clicking on one of the dotted lines (links) on the left hand side of the leaf? I see that it works, but it still doesn't really address the general question of giving the user a clear sense of context. It seems like this would be better as an infinite scroll to achieve the effect of on-demand loading without forcibly breaking things across pages. If there happened to be a really large number of children for a tree item, perhaps we could introduce a notion of an ellipsis in the child list, like this: - Numbers --- Integers - 1 - 2 - ... (click to show all) - 99 - 100 That way, you could keep the hierarchical context for easy skimming of the overall structure, yet the user can drill down explicitly when they have enough of an idea about where they want to look. It's sort of like cold folding in IDE. --~--~-~--~~~---~--~~ http://groups.google.com/group/Google-Web-Toolkit-Contributors -~--~~~~--~~--~--~---

[gwt-contrib] Re: gen2 TreeTable demo online
BTW: Right now the filters are only applied to the top level elements. I've tried other approaches but with confusing results for the user. Any suggestions how to apply the filters to children are welcome! I had the idea to add a chainsaw icon to the TreeController that will flatten the tree to a normal ScrollTable. Filtering could be applied to the flattened result and when switching back to tree view the selection could be kept. But this is not very intuitive...
