Drag on Drop Treeview

[herculanojs]

Hi

 

Would anyone have an example of how to do Drag Drop in a TUniTreeview

 

It would be possible ?

 

Tanks

Hi,

 

Yes it is possible, but you should think about synchronization with the server

function beforeInit(sender, config) {
    config.viewConfig = {
        plugins: {
            ptype: 'treeviewdragdrop'
        }
    };
}

Best regards,

[herculanojs]

thank you

    };
}

Best regards,

How could you make it so that in ondrag drop it could be added as no child in another?

[herculanojs]

How can I capture the Dragdrop event?

 

function beforeInit(sender, config) {
    config.viewConfig = {
        plugins: {
            ptype: 'treeviewdragdrop'
        }
    };
}

 

 

O código acima apenas permite o drag de uma posição superior/inferior. Necessito mover nós entre níveis. Colocar um nó dentre de outro. 

Como posso capturar o nó que esta sendo movido, e sobre qual nó esta sendo sobreposto.

 

The above code only allows drag from an upper / lower position. I need to move knots between levels. Put one knot from another.

How can I capture the node being moved, and which node is being overlapped.

 

in vlc

 

procedure TfrmGrupo.trvMenuDragDrop(Sender, Source: TObject;

  X, Y: Integer);

var

  AnItem: TTreeNode;

   AttachMode: TNodeAttachMode;

   HT: THitTests;

begin

     if trvMenu.Selected = nil then Exit;

        HT := trvMenu.GetHitTestInfoAt(X, Y) ;

     AnItem := trvMenu.GetNodeAt(X, Y) ;

     if (HT - [htOnItem, htOnIcon, htNowhere, htOnIndent]<> HT) then

     begin

          if (htOnItem in HT) or (htOnIcon in HT) then

             AttachMode := naAddChild

          else

          if htNowhere in HT then

             AttachMode := naAdd

          else

          if htOnIndent in HT then

             AttachMode := naInsert;

 

          trvMenu.Selected.MoveTo(AnItem, AttachMode);

 

   end;

end;

I need the dragdrop features contained in these examples

How can I achieve this with Unitreevew ?

[gerhardhziegler]

looks like, we have the same problems...

[herculanojs]

Does anyone have a solution for this situation?

Move an entire node with your children to another point, or to another node

[herculanojs]

We still have no solution to the problem. Does anyone have a solution?

I need to drag dragdrop between us, putting one inside of others, with all his children if they have. How can I do this? I did not find anything in the forum

[herculanojs]

Please, would there be any solution to the case

Need to analyze

[herculanojs]

OK, we have to deal with accounting plans, and it's tricky to deal with it without this option, as there are multiple levels of accounts, which can be changed.

Hello Sherzod !

We also are in the need of such a functionnality! Any workaround ? (:

Hello, 

The main logic of these things is done on the server side and stored in the database. Do you have server side logic using DB?

There is no problem to make the base side: just change one, node root, id. But graphical interface of drag-drop is ugly as in UniDbTreeView as in UniTreeView. And it's important for us.

I use UniTreeView, and the tree is stored in the database. I understand that I will need to implement the logic of moving nodes in storage on my own.
