_GuiCtrlTreeView_Add and OnEvent [SOLVED]

3 posts in this topic

#1 ·  Posted (edited)

_GUICtrlTreeView_BeginUpdate($tree)
    $root = _GUICtrlTreeView_Add($tree, 0, "PC - "& $pcname)
    _GUICtrlTreeView_SetIcon($tree,$root,"%SystemRoot%\system32\SHELL32.dll",15)
_GUICtrlTreeView_EndUpdate($tree)

I do not only want to expand this tree when I click the item, I also want to trigger an OnEvent funtion when I click it so I can update the child treeviewtems (which are retrieved via TCP/IP).

GuiCtrlSetOnEvent($root,"function") doesn't work, probably because the _GuiCtrlTreeView functions in autoit are some kind of UDF.

I tried WM_NOTIFY(), but that only registers the click/rightclick etc, not the item clicked on.

I was trying all kind of workarounds with mouse position lookup functions etc, but if someone knows a cleaner way to do this, I would be very happy!!

Thanks!

Hi, use the WM_NOTIFY() to get the click and _GUICtrlTreeView_HitTestEx() or _GUICtrlTreeView_HitTestItem() to find what treeview item has been clicked.

Thanks for the quick response!

Looks perfect. going to try that as soon as I'm on a windows PC again :)

--------------------------------

EDIT: Changed

$tPoint = _WinAPI_GetMousePos(True, $hWnd)

to:

$tPoint = _WinAPI_GetMousePos(True, $hWndTreeview)

Otherwise the mouseposition was wrong and it returned 1024 (Right of Control) instead of the 1 or 4 I wanted (Label/Icon)

---------------------------------

For anyone interested, all the cases are described in GuiTreeView.au3:

Func _GUICtrlTreeView_HitTest($hWnd, $iX, $iY)
    Local $iFlags, $iResult, $tHitTest

    $tHitTest = _GUICtrlTreeView_HitTestEx($hWnd, $iX, $iY)
    $iFlags = DllStructGetData($tHitTest, "Flags")
    If BitAND($iFlags, $TVHT_NOWHERE) <> 0 Then $iResult = BitOR($iResult, 1)
    If BitAND($iFlags, $TVHT_ONITEMICON) <> 0 Then $iResult = BitOR($iResult, 2)
    If BitAND($iFlags, $TVHT_ONITEMLABEL) <> 0 Then $iResult = BitOR($iResult, 4)
    If BitAND($iFlags, $TVHT_ONITEMINDENT) <> 0 Then $iResult = BitOR($iResult, 8)
    If BitAND($iFlags, $TVHT_ONITEMBUTTON) <> 0 Then $iResult = BitOR($iResult, 16)
    If BitAND($iFlags, $TVHT_ONITEMRIGHT) <> 0 Then $iResult = BitOR($iResult, 32)
    If BitAND($iFlags, $TVHT_ONITEMSTATEICON) <> 0 Then $iResult = BitOR($iResult, 64)
    If BitAND($iFlags, $TVHT_ABOVE) <> 0 Then $iResult = BitOR($iResult, 128)
    If BitAND($iFlags, $TVHT_BELOW) <> 0 Then $iResult = BitOR($iResult, 256)
    If BitAND($iFlags, $TVHT_TORIGHT) <> 0 Then $iResult = BitOR($iResult, 512)
    If BitAND($iFlags, $TVHT_TOLEFT) <> 0 Then $iResult = BitOR($iResult, 1024)
    Return $iResult
EndFunc   ;==>_GUICtrlTreeView_HitTest
