RE: [flexcoders] How would I do something like this....

[Doug Hughes]

Thanks everyone for the tips.  It sounds like this might be the quickest/easiest way to do this.  I’m not sure how I’m going to do this, but I’ll do it somehow. J   Thanks again!   Doug   From: flexcoders@yahoogroups.com [mailto:[EMAIL PROTECTED] On Behalf Of Anatole Tartakovsky Sent: Sunday, April 23, 2006 12:08 AM To: flexcoders@yahoogroups.com Subject: Re: [flexcoders] How would I do something like this....   Jeremy,     Actually, I was not suggesting to rewrite UI/datagrid - I was suggesting not to use tree - datagrid would work fine the way it is now. The changes to datagrid would be very "localized": just sorting to take in consideration the hierarchy (essentially making sure you have custom sort function based on parent preceding column  sort), minor changes like making sure first column locking works, etc. In either case the code is based on datagrid and not on the tree, with opening/closing of the nodes based upon filtering of the data, add custom renderer to the first column to paint / outdent first label and integrate it with filter function.     Quick and dirty approach allows you to do most of that code inline within the mxml/data definition itself doing the above code explicitly.   Thank you, Anatole   PS. Obviously, disabling sorting or column reordering would further simplify the task.     ----- Original Message ----- From: jeremy lu To: flexcoders@yahoogroups.com Sent: Saturday, April 22, 2006 11:14 PM Subject: Re: [flexcoders] How would I do something like this....   well, just flip thru my gridtree component (http://tinyurl.com/grcfs) developed two months ago (which is still in a mess), it's around 2000 lines of code (after refactoring it three times) and lot of algorithm behind to handle following function: addNode removeNode cutNode copyNode pasteNode indent/outdent code I think the first methods Anatole mentioned will definitely be a b***h to tackel with, for the nature of List-based component is a little bit tricky then it looks (all the list items are dynamically generated and draw on the screen, this will cause some trouble) I'm currently implementing gridtree using item renderer for the first column, it's pretty much the same work to extends gridbase and "inject" the tree grid code into it so the API would be more compatible, by using this method I could easily feed a non-xml structure (ie:resultset from java/php) to the component and let it draw the hierarchy and set indent/outdent of each node. now I'm thinking maybe I should draw those lines and plus sign instead of a simple arrowhead, so it's more like VS2005  :-) FYI, the component took a whole weekend for prototyping  and concept-proofing, *but*, it took almost one and a half month for debugging and refactoring to stablize the code and become really usable in the on-going product/project. originally I want to open-source the component but later on this become one of my assigned  day-job project (so I can fulltime developing it with the approval of my employer), but anyway, I would love to answer any related questions. jeremy.

Study the code for data grid header, treeview, datagrid, etc 3. Write your own code for the control inherited on the top of BaseGrid, with automatic wrapper for the first column - 1500-2000 lines in total to support generic case   For quick and dirty : Create first column as cell renderer. I believe I posted code in this group for Flex 1.5 tree cell renderer that allowed to add nodes lines to the regular tree - you just paint it within item - still about 200 lines of code for core functionality, another 100 lines for cascade retrieve/grouped sort on the header clicks, 2-3 days of work altogether   Have not seen anything in the public domain, just few developed "for hire" in consulting gigs.   HTH, Anatole -- Flexcoders Mailing List FAQ: http://groups.yahoo.com/group/flexcoders/files/flexcodersFAQ.txt Search Archives: http://www.mail-archive.com/flexcoders%40yahoogroups.com SPONSORED LINKS Web site design development Computer software development Software design and development Macromedia flex Software development best practice YAHOO!
