关于统计_GUICtrlListView_GetSelectedCount问题[已解决]
本帖最后由 blue_dvd 于 2012-11-18 22:50 编辑想要效果
主要是统计用户点击选择了多少个项目？
代码如下#include <GuiConstantsEx.au3>
#include <GuiListView.au3>
#include <WindowsConstants.au3>
GUICreate("ListView Click Item", 400, 300)
$hListView = GUICtrlCreateListView("", 2, 2, 394, 268, "", $LVS_EX_FULLROWSELECT+$LVS_EX_CHECKBOXES)
_GUICtrlListView_InsertColumn($hListView, 0, "Column 1", 200)
_GUICtrlListView_InsertColumn($hListView, 0, "Column 2", 150)
$hLabel = GUICtrlCreateLabel("已选定0个item", 2, 275, 394, 15)
GUISetState()
For $i = 1 To 20
GUICtrlCreateListViewItem("Row "&$i&": Col 1", $hListView)
Next
GUIRegisterMsg($WM_NOTIFY, 'WM_NOTIFY') ;注册侦测用户是否选择
While 1
Switch GUIGetMsg()
Case $GUI_EVENT_CLOSE
Exit
EndSwitch
WEnd
GUIDelete()
Func WM_NOTIFY($hWnd, $iMsg, $iwParam, $ilParam)
#forceref $hWnd, $iMsg, $iwParam
Local $tNMHDR, $hWndFrom, $iCode
$hWndListView = $hListView
If Not IsHWnd($hListView) Then $hWndListView = GUICtrlGetHandle($HListView)
$tNMHDR = DllStructCreate($tagNMHDR, $ilParam); $tagNMHDR - Contains information about a notification message
$hWndFrom = DllStructGetData($tNMHDR, 'hWndFrom')
$iCode = DllStructGetData($tNMHDR, 'Code')
Switch $hWndFrom
Case $hWndListView
Switch $iCode
Case $NM_CLICK
Local $aHit = _GUICtrlListView_HitTest($hListView)
If $aHit<>-1 And _GUICtrlListView_GetItemChecked($hListView,$aHit)=TrueThen
_GUICtrlListView_SetItemChecked($hListView,$aHit)
_GUICtrlListView_SetItemSelected($hListView, $aHit,True)
ElseIf $aHit<>-1 And _GUICtrlListView_GetItemChecked($hListView,$aHit)=FalseThen
_GUICtrlListView_SetItemChecked($hListView,$aHit,False)
_GUICtrlListView_SetItemSelected($hListView, $aHit,False)
EndIf
GUICtrlSetData($hLabel, "共选定项目为"&_GUICtrlListView_GetSelectedCount($hListView))
EndSwitch
EndSwitch
EndFunc总会出错，不知道什原因？代码比较幼稚，请各位不要笑的太厉害！
解决方法在8楼！ 看不懂什么意思 出错的地方原因是你48行后用的Id“$hListView”，而非句柄“$hWndListView”
处理这类问题，建议使用P版的“ListView UDF - ListView消息扩展”
http://www.autoitx.com/forum.php?mod=viewthread&tid=13175 lz这个问题有点毛病，selectcount是获取选定项的计数，不是复选项的计数 回复 1# blue_dvd

有没有统计复选项计数的函数？ 本帖最后由 netegg 于 2012-11-18 18:17 编辑

如果还是单选定(选定和复选不是一个意思)的话，不用函数，判断里设置个累加(累减)的变量就行了 本帖最后由 netegg 于 2012-11-18 18:13 编辑
这是单选的例子

多谢了，此为正解也！不过我如果双击项目发现没有选中，但$count却累加了！ 本帖最后由 netegg 于 2012-11-18 22:20 编辑
回复 9# blue_dvd
双击的话，消息是不一样的，需要另加一个双击处理才能得到正确的结果

case $nm_dblclk

回复 5# netegg
还有一个问题：变量$aHit是放什么数据的？查看函数HitTest发现了一堆英文！ - Zero based index of the item at the specified position, or -1
- If True, position is in control's client window but not on an item
- If True, position is over item icon
- If True, position is over item text
- If True, position is over item state image
- If True, position is somewhere on the item
- If True, position is above the control's client area
- If True, position is below the control's client area
- If True, position is to the left of the client area
- If True, position is to the right of the client area
求解释！ 本帖最后由 blue_dvd 于 2012-11-18 22:33 编辑

这段代码加到case $nm_Click后面不行
是不是要在声明一个函数才行？
Func WM_NOTIFY($hWnd, $iMsg, $iwParam, $ilParam)
#forceref $hWnd, $iMsg, $iwParam
Local $tNMHDR, $hWndFrom, $iCode
$hWndListView = $hListView
If Not IsHWnd($hListView) Then $hWndListView = GUICtrlGetHandle($hListView)
$tNMHDR = DllStructCreate($tagNMHDR, $ilParam) ; $tagNMHDR - Contains information about a notification message
$hWndFrom = DllStructGetData($tNMHDR, 'hWndFrom')
$iCode = DllStructGetData($tNMHDR, 'Code')
Switch $hWndFrom
Case $hWndListView
Switch $iCode
case $nm_dblclk
return 1
EndSwitch
EndSwitch
EndFunc ;==>WM_NOTIFY
是状态图像
case $nm_dbclk放到setdata下面 回复 11# blue_dvd
