[SOLVED]Stop calling OnClicked event when DragnDropFromControl in treecontrol ?

[stephan_35]

Hello,

I discover that event "OnClicked" is called again before DragnDropFromControl, and that maybe because DragnDropFromControl event delete the node or because of changing node (depending if move or copy).

"Onclicked" is selected first !

My question is, could it be easy for you to stop calling "Onclicked" event ???

Yes, because, i didn't clicked anything else after droping action in TreeControl !

Best Regards & thanks.

I don't understand the problem. I did a quick test, and indeed OnClicked is called when you select a tree item with the mouse to begin a drag and drop operation. This is working as it should, I think.

Hello,

Some news, now i can't know wich item was selected on dragndrop event !!!

After select one, oneclicked event return the good one,
If you select another item and if you directky move it to  another item , there is no way to know wich one was selected !

As i explain onClicked return the next selected item after move action,(and no the selected item)

That is a problem for me ! thanks for help

The solution should be return in DragnDropFromControl event  the SelectedItem "From"  (like droppoint), or return in OnClicked event the selected item "From" ....

Best regards .

It sounds like you have trouble because asynchronous events do not fire until AutoCAD is quiescent.  Do you have better luck if you change the tree control's Event Invoke property to 'Synchronous'?

I don't know how to get the selected item within dragndropfromcontrol event !

Do you mean the destination item, or the source item? The source should be the one that was selected in OnClicked; the destination item should be passed as the last argument to OnDragnDropFromControl.

I mean source item (or From item), and i know that the source should be return by Onclicked event !

That is what i try to explain to you from the begining :it's impossible to know wich item was selected because onClicked does not return the correct selected item, it return only next selected item after move action !!!!!!!

I know that i must improve my english  ;D

Thanks for help

Hello owen,


you can have a see here :

When i move node24 to  node3 Onclicked event return node25 ???

When i drop directly node29 to node4, never seen Onclicked event "Node29" !!!!!


Thanks

Best regards

[owenwengerd]

I watched your video, and it helps me understand what you are saying.

When i move node24 to  node3 Onclicked event return node25 ???

  This looks correct to me. Node 25 is "selected" after the drag/drop operation is completed because Node 24 no longer exists.

When i drop directly node29 to node4, never seen Onclicked event "Node29" !!!!!

I will see if I can reproduce this.

[owenwengerd]

I tested, and I could not see any bug in the code. In my test, the OnClicked event always fires when it should. The problem you have is that in the case of a drag and drop operation, OnClicked does not fire until after the drag and drop operation completes. This is working as designed.

To accomplish what you want, you'll need to either handle the OnSelChanged event, or better, call GetSelectedItem from the OnDragnDropBegin event. During OnDragnDropBegin the source item will be the current selection.

Hello owen,

here is what i try, as you suggest me :

Event "SelChanged" :

During DragnDrop action ,nothing has changed !
Return only the last know position as getselecteditem, but no the selected item witch has been moved !
in fact the same as "OnClicked" event !

GetSelectedItem during OnDragnDropFromControl :
Get the last selected item

GetSelecteditem during OnDragnDropBegin :

YES!!! This work fine BUT: CTRL KEY & SHIFT KEY has no effect during Drag & Drop ation, so no choice of copy or move !!!!  >:( as i explain in another post ....

so, what could i do now !

I really hope to find an issue  ;D

Thanks.

Best regards.

hello owen.

I'm afraid about modify DragnDropFromControl event and catch the seletitem before it was moved or copy ???
or any event to catch the selected item before it has been moved ...

I know how much time you may spend on it .....

I'm afraid about go round in circles .... ;D

Thanks

Best regards.

I've made a change in the next build to allow both move and copy even when OnDragnDropBegin is enabled. Please test it and let me know whether the change causes any problems.
