Hi, I did the same GridTree but with the Flash Components V2 and now I would like port my app to Flex. But I use another way, I put the datagrid immediately at the right side of the tree. This work fine and I think is a more ease solution, because your base is the tree and not the datagrid, then you can manage more ease the xml data and don't need to deal with itemrenderer in the datagrid, only the checkboxes in the tree.
Now, I'm really newbie with Flex and I can't get the length of the only visible items in the tree :( Really stupid, but this is my first time with flex, I can't see nothing in the Tree and XML classes. thanks in advance Rafael --- In flexcoders@yahoogroups.com, "jeremy lu" <[EMAIL PROTECTED]> wrote: > > 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. > > > On 4/23/06, Anatole Tartakovsky <[EMAIL PROTECTED]> wrote: > > > > Depends on your requirements: > > For generic case it is 3 step process: > > 1.
