Drag Items from Treeview to Listview

5 posts in this topic

Is it possible to Drag&Drop items from treeview to listview with a drop indicator on a 64bit system?

i found this code but i getting confused with adding the listview make it drop-able and move the drop indicator to the listview.

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

;Opt("GUICloseOnESC", 0)
Opt("GUIOnEventMode", 1)

$sTitle = "Treeview Drag & Drop Editing"
;Required global constants:
Global $bTreeDrag = False, $bTreeEdit = False, $hDragItem, $hTreeDragImage, $fWhere

$hGui = GUICreate($sTitle, 400, 300, -1, -1, -1, -1)

$label = GUICtrlCreateLabel("Drag and drop separate items or branches to move them." & _
                        @LF & "To start edit selected item, LMB on item or press Enter." & _
                        @LF & "To end editing, LMB outside item (apply) or Esc (cancel) / Enter (apply)." & _

I dont know if i'm right or wrong, but i think you need to use _GUICtrlTreeView_Create instead of GUICtrlCreateTreeViewItem.

I dont think GUICtrlCreateTreeViewItem supports drag and drog

I haven't tested it.

It seems to act the same.

but i progressed a bit using pieces of code i found in the forum. now i facing two problems:

1. when dragging the object it will disappears one it's on the gui backgroud

2. how to drop it to the listview
