TreeView怎么获取父项id
本帖最后由 qsy666888 于 2014-7-31 12:55 编辑我看了以前的水木子大侠的示例，但我还是没有弄出来

我提到的这种跟水木子大侠的示例似同非同，一直没有弄出来，不知道用什么代码去获取这种情况的id。
在此感谢谢大大们对我的耐心的帮助。#include <GUIConstantsEx.au3>

user3000大侠，父项的 id 能不能获取 回复 3# qsy666888
_GUICtrlTreeView_GetParentParam
有了句柄,还要ID来作什么?
还有,你应该要多花一些时间和耐心去观看帮助的众多示例, 多多测试之! 回复 4# user3000
我想获取它的id来展开指定的父项，我试过好多代码，必须要父项的id才行 回复 4# user3000

这些疑难杂症，我们这些鼠辈肯定弄不出来 回复 4# user3000
还是没有弄得出来，哎！谢谢你 回复 7# qsy666888
_GUICtrlTreeView_GetParentParam
此函数可以获取到父项目的ID,如果有父项目的吧! 回复 8# user3000
我试过了，不得行 回复 9# qsy666888
你把下面代码加入到2楼代码的51行后面测试. Local $Id_P = _GUICtrlTreeView_GetParentParam($hTreeView, $hItem)
MsgBox(0, '父项目ID(0为根项目):' & $Id_P, GUICtrlRead($Id_P, 1))发觉很难与你交流;似乎是我在提问?!你还有问题,应该详细描述出来吧,单单回个"不行",算是什么回事呢! 回复 10# user3000
谢谢谢谢，不好意思，心里太着急了 回复 11# qsy666888
别急！这些东西急不来的，。
参考函数：_GUICtrlTreeView_Expand
