难题：在TreeView中能否实现右键单击某项便可显示点击项目的名称？[已解决]
本帖最后由 shuren88 于 2012-3-22 10:15 编辑以下代码可以在TreeView中实现鼠标左键单击某项，便可以显示点击项目的名称。
能否实现鼠标右键单击某项，便可以显示点击项目的名称？这是否是Autoit的TreeView中的难题？
搜索了很久没有任何蛛丝马迹，恳请大侠们不吝赐教，先谢了！#include <GUIConstantsEx.au3>

EndFunc ;==>_OnNotify $TVN_SELCHANGEDA, $TVN_SELCHANGEDW这两个是什么样的通知我不清楚但改成$NM_RCLICK就是右键了 直接改为$NM_RCLICK，我先就已经试验了，不行。我右键单击了某项，比如Other，它始终显示原先选中的项目General，见下图。也就是说，右键单击了某项不能选择项目，更不能显示选择的项目名称，这真是个难题。

老大，这几个函数的前提都是需要事先知道要选中项目的信息，再进行设置。我希望解决的问题是右键选中项目并得到项目信息。这几个函数我都试验过，不能解决右键选中项目的问题。 本帖最后由 netegg 于 2012-3-21 23:53 编辑

上面那三个函数用来枚举指定条件的项，获取项索引或者句柄，然后就出来了
如果觉得这样麻烦，就用消息，获取点击消息，然后获取文本
不过最终还是要获取到项目句柄或索引 回复 6# netegg
老大，按你的思路试了一下，还是老问题，右击某项还是无法改变原来选中的项目。可以显示，但显示的任然是原来选中的项目，而非右击的项目。代码如下：#AutoIt3Wrapper_Au3Check_Parameters=-d -w 1 -w 2 -w 3 -w 4 -w 5 -w 6

我觉得 这是TreeView特性吧, 一定要用鼠标左键才可选中项目.
所以我认为稍稍变通一下吧, 点击右键时模拟点击下左键
执行效果还行.Func WM_NOTIFY($hWnd, $iMsg, $iwParam, $ilParam)

经过测试，这种方式最优：
