Right Click in Tree View

[ericg32 0]

Probably one of the simplest questions tonight ! But how do I capture that the user pressed the right mouse button on an item.. using the sample treeview from the help files ?

[rasim 20]

#include <GUIConstants.au3>
#Include <GuiTreeView.au3>

$gui = GUICreate("Test", 200, 200)
$tree = GUICtrlCreateTreeView(10, 10, 100, 150, -1, $WS_EX_CLIENTEDGE)
$all = GUICtrlCreateTreeViewItem("All", $tree)
$first = GUICtrlCreateTreeViewItem("First", $all)

GUISetState()

While 1
    $msg = GUIGetMsg()
    
    Select
        
    Case $msg = -3
        ExitLoop
        
    Case $msg = $GUI_EVENT_SECONDARYUP
        $CurPos = GUIGetCursorInfo($gui)
        If $CurPos[4] = $tree And _GUICtrlTreeViewGetState($tree, $first) = 2 Then MsgBox(0, "", "Selected")
    
    EndSelect
WEnd

Out of the Beta Help, the WM_NOTIFY can be used with AutoIt created Tree control also.

Note the $NM_RCLICK
