ListView Drag and Drop

[jNizM]

Request for v2 (maybe v1.1 too)

From ahk:

Code: Select all

https://autohotkey.com/docs/commands/ListView.htm#notify
D: The user has attempted to start dragging a row or icon (there is currently no built-in support for dragging rows or icons). The variable A_EventInfo contains the focused row number. In v1.0.44+, this notification occurs even without AltSubmit.

From au3:

Code: Select all

https://www.autoitscript.com/autoit3/docs/functions/GUICtrlSetState.htm
$GUI_DROPACCEPTED (8)    -    Control will accept drop action : from file or from a drag of another control. See remarks.

If $GUI_DROPACCEPTED (8) is set to a visible control a drag & drop can be taken in account. The edit/input control will be set with the filename.
For other controls on reception of $GUI_EVENT_DROPPED, @GUI_DragId will return the controlID from where the drag start (-1 if from a file, @GUI_DragFile contain the filename being dropped) and @GUI_DropId returns the controlID of the dropped control.
Only dragging a ListviewItem will start the drag & drop process. The @GUI_DragId will be the ListView controlID.

e.g.

Code: Select all

Dim $LISTVIEW_ITEM[10]

$GUI = GUICreate("Drag'n'Drop",800,600,-1,-1)
$LISTVIEW_LEFT = GUICtrlCreateListView("Column 1|Column 2|Column 3|Column 4",0,0,400,600)
GUICtrlSetState(-1, 8) ; $GUI_DROPACCEPTED = 8

For $i = 0 To 9
    $LISTVIEW_ITEM[$i] = GUICtrlCreateListViewItem("Item "&$i,$LISTVIEW_LEFT)
Next

$LISTVIEW_RIGHT = GUICtrlCreateListView("Column 1|Column 2|Column 3|Column 4",400,0,400,600)
GUICtrlSetState(-1, 8) ; $GUI_DROPACCEPTED = 8

GUISetState(@SW_SHOW)

While True
    Switch GUIGetMsg()
        Case -3
            ExitLoop
        Case -13
            MoveItem(@GUI_DragId, @GUI_DropId)
    EndSwitch
WEnd

Func MoveItem($drag, $drop)
    GUICtrlCreateListViewItem(GUICtrlRead(GUICtrlRead($drag)), $drop)
    GUICtrlDelete(GUICtrlRead($drag))
EndFunc

Agreed!

Seems about right, the problem is trying to find a way to keep what the icon or column or even row to a variable to use. I would guess it would be A_EventInfo but there could be a lot more added to it.
