[已解决]listview中怎样随键盘光标改变而读取相数据

本帖最后由 jycel 于 2010-4-30 18:38 编辑

解决方法：7楼
在listview中我们可以通过鼠标点击一行，并获取相应数据，不知道通过键盘的光标来移动位置从而获取数据呢？

代码如下：#include <EditConstants.au3>
#include <GUIConstantsEx.au3>
#include <ListViewConstants.au3>
#include <WindowsConstants.au3>
#Include <GuiListView.au3>
GUIRegisterMsg($WM_NOTIFY, "WM_NOTIFY")
#Region ### START Koda GUI section ### Form=
$Form1 = GUICreate("listview测试", 288, 243, 401, 193)
$ListView1 = GUICtrlCreateListView("1|2|3|4", 8, 0, 273, 153)
GUICtrlSendMsg(-1, $LVM_SETCOLUMNWIDTH, 0, 50)
GUICtrlSendMsg(-1, $LVM_SETCOLUMNWIDTH, 1, 50)
GUICtrlSendMsg(-1, $LVM_SETCOLUMNWIDTH, 2, 50)
GUICtrlSendMsg(-1, $LVM_SETCOLUMNWIDTH, 3, 50)
GUICtrlCreateListViewItem("1|2|3|4", $ListView1)
GUICtrlCreateListViewItem("21|22|23|24", $ListView1)
GUICtrlCreateListViewItem("31|32|33|34", $ListView1)
GUICtrlCreateListViewItem("41|42|43|44", $ListView1)
GUICtrlCreateListViewItem("51|52|53|54", $ListView1)
$Input1 = GUICtrlCreateInput("", 8, 168, 121, 21)
$Input2 = GUICtrlCreateInput("", 160, 168, 121, 21)
$Input3 = GUICtrlCreateInput("", 8, 200, 121, 21)
$Input4 = GUICtrlCreateInput("", 160, 200, 121, 21)
GUISetState(@SW_SHOW)
#EndRegion ### END Koda GUI section ###

While 1
$nMsg = GUIGetMsg()
Switch $nMsg
Case $GUI_EVENT_CLOSE
Exit

EndSwitch
WEnd
Func WM_NOTIFY($hWndGUI, $MsgID, $WParam, $LParam)
Dim $lyListView1
   Local $tagNMHDR, $Event, $hWndFrom, $IDFrom
   Local $tagNMHDR = DllStructCreate("int;int;int", $LParam)
   If @error Then Return $GUI_RUNDEFMSG
   $IDFrom = DllStructGetData($tagNMHDR, 2)
   $Event = DllStructGetData($tagNMHDR, 3)
   $tagNMHDR = 0
   Switch $IDFrom;选择产生事件的控件

            Case $ListView1

                     Switch $Event; 选择产生的事件

Case $NM_CLICK ; 左击
$Index = _GUICtrlListView_GetSelectedIndices($ListView1)
                                    If Not StringLen($Index) Then; 这里用以判断是否选定了ListViewItem
Return
Else
GUICtrlSetData($Input1,_GUICtrlListView_GetItemText($ListView1, Number($Index),0))
GUICtrlSetData($Input2,_GUICtrlListView_GetItemText($ListView1, Number($Index),1))
GUICtrlSetData($Input3,_GUICtrlListView_GetItemText($ListView1, Number($Index),2))
GUICtrlSetData($Input4,_GUICtrlListView_GetItemText($ListView1, Number($Index),3))

EndIf
Case $NM_DBLCLK ; 双击

                           Case $NM_RCLICK ; 右击

                     EndSwitch
   EndSwitch

   Return $GUI_RUNDEFMSG
EndFunc ;==>WM_NOTIFY

截取LVN_KEYDOWN通知，判断VKey-Code是否为38（Up-arrow）或40（Down-arrow）。
结构定义：hWnd hWndFrom;int IDFrom;int Code;word VKey对于3.3.5.3之前的版本，把word改成short。

我试下看！

jycel 发表于 2010-4-30 16:44:04

我这样改的达到了效果，但是在第一个和最后一个再移动的话就得到的是空值，应该在判断上面再修改下
