DragDrop ListView Elements with Multiple ListViews in GUI

JohnBailey · August 15, 2007

As you can see below, I'm trying to enable the ability to drag listview items from one side to the other (which I did) and then back again (which I can't seem to do). The problem seems to be that using the GUISetOnEvent($GUI_EVENT_DROPPED, "funcName") is limiting. What I need is each listview to be a "hitspot" of sorts. I looked through msdn to find a listview mouse click release (which I couldn't find) and then use gaFrosts method of clicking the listview elements. This ended in a dead end for me. There may be a way to do all of this through MouseGetPos () method and create pseudo hit spots. I don't really know the best way.

This works but you might need to add some checks to make sure that the dragging started from the other listview. At the moment it is assumed that when something is dropped in one of the list views it comes from the other one.

Yep, that's good. I'd forgotten about @GUI_DropID and @GUI_DragID so now that you've done that you don't need my code.

Great code!

I've been trying to get the name of the dragged item with something like

$current = _GUICtrlListViewGetHotItem ($LV_DropToHere)
or  $current = _GUICtrlListViewGetItemText($LV_DropToHere, _GUICtrlListViewGetSelectedIndices($LV_DropToHere))
    MsgBox(0, "Dropped item was" & $current)

but haven't succeeded.

What am I doing wrong?

JohnBailey · August 27, 2007

Well, the easiest thing to do is to edit the _GUICtrlListViewCopyItems() function in _GUIListView.au3 file so it will return the text(s). Then, you can set _GUICtrlListViewCopyItems() to a var. The var will be an array with the text of the copied item(s). Therefore, allowing you to do something like the following

For $o = 1 to Ubound($list)-1
  $current = _GUICtrlListViewGetItemText($lv, $list[$o])
  MsgBox(0, "Dropped item was",$current)
Next

But this may not be the truly easiest thing, especially considering you have to edit a standard UDF. Besides, others are probably going to yell at me for even suggesting it. I just didn't like that CopyItem doesn't return much of anything, but that's probably because of a blindness on my part. I'll keep thinking of an easier way. You also might not want to do GUISetOnEvent($GUI_EVENT_DROPPED, "Dropping") and do a GUISetOnEvent($GUI_EVENT_PRIMARYDOWN,"Dropping"). However, that means entirely changing the Dropping function.

Not a good Idea to suggest changing the UDF functions, next install it would be overwritten, so the best suggestions would be to create your own functions that does what you want.

Sorry, gaFrost

I'm working to supply a different method. Moreover, yeah guwguw, you could take the CopyItem function from the UDF, put it in your file, adapt it (changing it's name of course), and then you get what I was mentioning. Still this probably isn't the best idea, especially since what I'm going to show you would do what you want without having to do it.

Again, sorry for suggesting something like that. Just throwing my ideas out there.

It's kind of funny because I said someone would come along and "yell" at me for suggesting changing the UDFs and someone did thanks Gafrost and I'll suggest different things from now on

Edit:

I didn't say it was bad idea or that someone could mess things up.

                Local $lvDest = $LV_DragFromHere
        EndSwitch
        
        If _IsPressed(1) Then;if the left mouse button pressed(must be really or how did we get here)
            $noSel = _GUICtrlListViewGetSelectedCount($lvSource);the number of selected items being dragged
            
            If $noSel < 1 Then Return
            
            Local $SelItems = _GUICtrlListViewGetSelectedIndices($lvSource);the list of the items
            Local $SelItemsArray = StringSplit($SelItems,'|')
            Local $SelItemsArraySize = Ubound($SelItemsArray)-1
            Local $TextArray[$SelItemsArraySize+1]
            For $iii = 1 to $SelItemsArraySize
                $TextArray[$iii] = _GUICtrlListViewGetItemText($lvSource,$SelItemsArray[$iii])
            Next
                
            While _IsPressed(1)
                ;wait for dragging to stop
            WEnd
                
                            
            ;where is the cursor now?
            $Info =  GUIGetCursorInfo (WinGetHandle($ParentWin))
            If $Info[4] = $lvDest Then;if it's still over the listview
                _GUICtrlListViewCopyItems ($lvSource, $lvDest, 1)
                Local $copiedEntries = ''
                For $iii = 1 to $SelItemsArraySize
                    $copiedEntries &=$TextArray[$iii]&' at position '&$SelItemsArray[$iii]&@LF
                Next
                MsgBox(0, "Dropped item was",$copiedEntries)
            EndIf
        EndIf
        
    EndIf
EndFunc

What I changed is how it shows the items copied.

Thanks for the quick help guys!

I'm still playing around with your suggestions, but the rest of the program doesn't really care which detail I choose- as long as the items get passed on to the rest of the environment.

I was pretty much convinced that I overlooked something, but now see that only a deeper knowledge of Autoit (like yours, lol) could solve the problem satisfactorily. I had needed something similar for list boxes (but ultimately used combo boxes), and managed to figure it out by researching these forums (and the help file, naturally) ...

Thanks again

No thanks. Currently I'm quite happy with the progress

We'll see what else pops up ...
