[已解决]Treeview中怎么读取所选择项目的值？

jycel

解决方法：三楼
第一次使用树型结构，帮助中都代有选择和图片，用不上！
问题如下图：当我点击历史图片下面的所有内容时，读取所选择的值即可！
功能就是读取所选择项目，然后更改对应的图片显示至图片框

image.ini配置如下
[历史]
9234=;值为关键字.jpg
8234=;同上

给你一个事例，自己参考一下

#include <GUIConstantsEx.au3>
#include <ListViewConstants.au3>
#include <WindowsConstants.au3>
Opt("GUIOnEventMode", 1)
#Region ### START Koda GUI section ### Form=
$Form1 = GUICreate("读取所选择项目的值　事例", 382, 139, 214, 150)
GUISetOnEvent($GUI_EVENT_CLOSE, "Event")
$ListView1 = GUICtrlCreateListView("读取所选择项目的值", 40, 24, 305, 89)
GUICtrlSendMsg(-1, $LVM_SETCOLUMNWIDTH, 0, 300)
$ListView1_0 = GUICtrlCreateListViewItem("这是第一行", $ListView1)
GUICtrlSetOnEvent($ListView1_0, "Event")
$ListView1_1 = GUICtrlCreateListViewItem("这是第二行", $ListView1)
GUICtrlSetOnEvent(-1, "Event")
GUISetState(@SW_SHOW)
#EndRegion ### END Koda GUI section ###

While 1
   Sleep(100)
Wend

Func Event()
   Switch @GUI_CtrlId
      Case $GUI_EVENT_CLOSE
         Exit
      Case Else
         $Val = GUICtrlRead(@GUI_CtrlId,1)
         $Val = StringReplace ( $Val, "|","")
         msgbox(0,0,"你点中的文字是“" & $Val & "”")
   EndSwitch
EndFunc

OK解决了！应该还有其它方法！下来慢慢研究！
代码如下:

#NoTrayIcon
#include <GUIConstantsEx.au3>
#include <StaticConstants.au3>
#include <TreeViewConstants.au3>
#include <WindowsConstants.au3>
#include <GuiConstantsEx.au3>
#include <GuiTreeView.au3>
#include <GuiImageList.au3>
#include <WindowsConstants.au3>
Opt("GUIOnEventMode", 1)
Local $_INI_File = @ScriptDir & "\Image.ini";读取配置文件
if not FileExists($_INI_File) then 
msgbox(16,"错误提示","未找到Image.ini配置文件"&@CRLF&"请手动建立"&@CRLF&"字段名为[历史]",5)
Exit
EndIf
#Region ### START Koda GUI section ### Form=C:\Documents and Settings\Administrator\桌面\Form1.kxf
$Form1 = GUICreate("图片查看器", 587, 373, 216, 186)
GUISetOnEvent($GUI_EVENT_CLOSE, "Event")
$Group1 = GUICtrlCreateGroup("", 2, 0, 468, 369)
$Pic1 = GUICtrlCreatePic("", 8, 8, 457, 353)
GUICtrlCreateGroup("", -99, -99, 1, 1)
$Group2 = GUICtrlCreateGroup("", 472, 0, 113, 369)
$TreeView1 = GUICtrlCreateTreeView(480, 14, 97, 321)
GUICtrlSetOnEvent(-1, "Event")
$Button1 = GUICtrlCreateButton("退出查看器", 480, 344, 97, 20, -1, $WS_EX_STATICEDGE)
GUICtrlSetOnEvent(-1, "Event")
$item=GUICtrlCreateTreeViewItem("历史图片", $TreeView1)
$IniSection = IniReadSection($_INI_File, "历史");读取配置文件主值
if not @error Then
        For $i = 1 To $IniSection[0][0]
                $datez=GUICtrlCreateTreeViewItem($IniSection[$i][0],$item)
                GUICtrlSetOnEvent(-1, "Event")
        Next
EndIf

GUICtrlCreateGroup("", -99, -99, 1, 1)
GUISetState(@SW_SHOW)
#EndRegion ### END Koda GUI section ###

While 1
Sleep(100)
WEnd
Func Event()
   Switch @GUI_CtrlId
      Case $GUI_EVENT_CLOSE
         Exit
          case $Button1
                        Exit
      Case Else
         $Val = GUICtrlRead(@GUI_CtrlId,1)
         $Val = StringReplace ( $Val, "|","")
                 GUICtrlSetImage($Pic1,IniRead($_INI_File,"历史",$Val,""))
   EndSwitch
EndFunc
