TreeView selected item

3 posts in this topic

hey guys,

I am having an issue with my treeview control. I want to get the text of a selected item, but only when I click on THE item, not when I click on the expand symbol (+). Could anyone help? Or if it was already raised and resolved, point me to the right thread?

$treeViewOUs = GUICtrlCreateTreeView(16, 232, 209, 345, BitOR($TVS_HASBUTTONS, $TVS_HASLINES, $TVS_LINESATROOT, $TVS_DISABLEDRAGDROP, $TVS_SHOWSELALWAYS), $WS_EX_CLIENTEDGE)
Global $hTreeView = GUICtrlGetHandle($treeViewOUs)
Func WM_NOTIFY($hWnd, $Msg, $wParam, $lParam)
Local $tNMHDR, $IdFrom, $iCode
$tNMHDR = DllStructCreate($tagNMHDR, $lParam)
$hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom"))
$IdFrom = DllStructGetData($tNMHDR, "IdFrom")
$iCode = DllStructGetData($tNMHDR, "Code")
     Switch $hWndFrom
     Case $hTreeView
         Switch $iCode
             Case $NM_CLICK
     ConsoleWrite(_GUICtrlTreeView_GetText($hTreeView,_GUICtrlTreeView_GetSelection($hTreeView)) & @CRLF)
         EndSwitch
EndSwitch
Return $GUI_RUNDEFMSG
EndFunc ;==>_WM_NOTIFY

Furek86,

I would do it like this - the "click" comes first and arms an Adlib function. If if it is followed almost immediately (withint 5 ms on my machine) by an "expand/contract" message we cancel the Adlib function: ;)

#include <GUIConstantsEx.au3>
#include <WindowsConstants.au3>
#include <GuiTreeView.au3>

$fClicked = False

$hGUI = GUICreate("Test", 500, 500)

$treeViewOUs = GUICtrlCreateTreeView(16, 32, 209, 345, BitOR($TVS_HASBUTTONS, $TVS_HASLINES, $TVS_LINESATROOT, $TVS_DISABLEDRAGDROP, $TVS_SHOWSELALWAYS), $WS_EX_CLIENTEDGE)
Global $hTreeView = GUICtrlGetHandle($treeViewOUs)
$generalitem = GUICtrlCreateTreeViewItem("General", $treeViewOUs)
$displayitem = GUICtrlCreateTreeViewItem("Display", $treeViewOUs)
$aboutitem = GUICtrlCreateTreeViewItem("About", $generalitem)
$compitem = GUICtrlCreateTreeViewItem("Computer", $generalitem)
GUICtrlCreateTreeViewItem("User", $generalitem)
GUICtrlCreateTreeViewItem("Resolution", $displayitem)
GUICtrlCreateTreeViewItem("Other", $displayitem)

$cClk_Dummy = GUICtrlCreateDummy()

GUISetState()

GUIRegisterMsg($WM_NOTIFY, "_WM_NOTIFY")

While 1

    Switch GUIGetMsg()
        Case $GUI_EVENT_CLOSE
            Exit
    EndSwitch

WEnd

Func _Read()
    ConsoleWrite(_GUICtrlTreeView_GetText($hTreeView, _GUICtrlTreeView_GetSelection($hTreeView)) & " <<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<<" & @CRLF)
    AdlibUnRegister("_Read")
EndFunc   ;==>_Read

Func _WM_NOTIFY($hWnd, $iMsg, $wParam, $lParam)

    $tNMHDR = DllStructCreate($tagNMHDR, $lParam)
    $hWndFrom = HWnd(DllStructGetData($tNMHDR, "hWndFrom"))
    $iCode = DllStructGetData($tNMHDR, "Code")
    Switch $hWndFrom
        Case $hTreeView
            Switch $iCode
                Case $NM_CLICK
                    AdlibRegister("_Read", 20)
                    ConsoleWrite("Registered" & @CRLF)
                Case $TVN_ITEMEXPANDEDW, $TVN_ITEMEXPANDEDA
                    AdlibUnRegister("_Read")
                    ConsoleWrite("Unregistered" & @CRLF)
            EndSwitch
    EndSwitch
EndFunc   ;==>_WM_NOTIFY

I have left the ConsoleWrite lines in so you can see what is happening. :)
