Drag ListView Item

[GaryFrost]

Found a type-o, so when moving an item after it's been moved at least once causes it not to delete

Replace:

_GUICtrlListViewDeleteItem($ListView, $From_index)
oÝ÷ Ùh­«­¢+Ø($%}U%
Ñɱ1¥ÍÑY¥Ý±Ñ%Ñ´ ÀÌØí¡}1¥ÍÑY¥Ü°ÀÌØíɽµ}¥¹à¤

I don't get it to work. Latest Beta, WinXP.

Any idea?

Comment out that line and it should work. Its old code, the include files have changed since then and currently have that already declared.

Comment out that line .....

Got it, only line 41+42 have to be commented out.

Looks real professional.

Is it poosible to get it autoscroll if I have more than 9 LV-Items and want to drag somewhere to the end.

For example 20 LV-Items (in SciptLine 74).

Thanks (in advance) Reinhard

Wow this is awesome. I havent used it only this example.

Updated 1st post, give it a try.

Hi Gary,

I like your short statements and quick response.

It works good so far, but there seems to be a probleme with the mouse shadow (or screen update)

If I drag down (9->20) it leaves the mouse shadow from item [+] 9 .. at the top of the downscrolled LV (somwhere at 11).

If I drag then up (18->5) and LV-box scrolls up, the upper listview items become unreadable (much mouse shadows cause this I think). The LV can then be updated with scrolling up and down.

Howerever it shows that it can be done. I have to look deeper in it to understand - at least a little bit - how it works.

Thanks for all your work on this item.

I mentioned this in the 1st post, just haven't had time to look into it.

Added: auto scrolling when dragging (quick and dirty, might be a better way to do this. Note: this causes a repaint problem)

[ReFran]

"I mentioned this in the 1st post ...................."

Yeaaa, sometimes reading helps a lot.

" .... just haven't had time to look into it."

My LV works fine with up/down buttons. Dragging would only be a highlight.

So there is nothing to do urgent.

best regards, Reinhard

" .... auto scrolling when dragging (quick and dirty, might be a better way to do this. Note: this causes a repaint problem)"

Got it. At least a good working example.

On dragingstart I use: DllCall("ComCtl32.dll", "int", "ImageList_EndDrag")

to switch out the draging mouse image - which cause the problems if scrolled up - and attach a tooltip with the listviewitem text to the mouse.

That looks good/professional and works perfect. I have to think about a tooltip Icon to attach ;-).

Another way would be to switch out in front of "_GUICtrlListViewScroll" and on after that, but untested and may tend to flicker.

By the way a good and simple replacement for "_GUICtrlListViewScroll" is MouseWheel("up"/"down").

In the start I want to switch Cursur ID from arrow to "grabbing hand", which is not posible with "GUISetCursor(..)".

If you know a way to do it by a DllCall it would be fine if you can state it here.

Thanks for all your help, Reinhard

I would be carefull using MouseWheel, your assuming the ListView has the focus.

Also found out that if you use the Built-in ListView then there is the repain problem in using the DragImage, didn't see that problem with Creating your own ListView.

"....... I would be carefull using MouseWheel, your assuming the ListView has the focus."

Will pay attention to that.

"...... didn't see that problem with Creating your own ListView."

Perhaps in my next project. At time, the tooltip solution looks professional enough.
