flex2 component - Tree with checkbox

In flex September 16, 2006 - 10:00 am

Just made this for the project I’m currently working on, main features include:

-when branch selected, all child node will be selected

-when branch is de-selected, all child node will be de-selected too

-when some of the children were selected but some are not, branch(parent) node will be greyed out.

-when the Tree first initialized, branch will restore to correct status (to grey out, select, or not)

Thanks to the new framework, it’s quite easy to made this kind of stuff.

这个是FLEX2自带的么？还是FB2提供的？

Tree, checkbox 都是 Flex 內建的，再加上自製的 item renderer 與 programmatic skin.

就是用自製的 item renderer 取代 Tree 原本使用的，然後在這個 renderer 裏的 createChildren()建立一個 checkbox元件，再建一個新的 skin class 來畫出灰色的 checkbox 背景(代表未全部選取)，這樣就差不多了。

至於選取的行為就是用 recursive 去跑一輪就好。
