The Tree control is a List control and can use itemRenderers and itemEditors. See the Flex 2 documentation on creating itemRenderers and on creating custom components.1 person found this helpful
To be honest, it isn't something you should tackle without going through the Flex 2 QuickStarts/Tutorials as creating a new component is pretty advanced.
Thank you for your answer, first.
Even though I don't know well about it, I think it seems that more complex structure is needed for it.
How about rendering performance? Isn't there any rendering performance penalty?
Because my new project which my company is planing is targeting huge number of list items, I have to consider that.
In addition to it, I'd like to know about performance issue of Flex2 platform, if there is.
Could you introduce me any document about it?
"huge number of list items.." is a bad idea. Performance will be a problem, even with stock controls, though Flash 8 - 9 have much improved rendering speed.1 person found this helpful
If you really have large numbers of items, seriously considering a paging strategy.
