    Question Unanswered: TreeViewDragDrop: how to allow drop on all nodes, showing only "append" icon

    Unanswered: TreeViewDragDrop: how to allow drop on all nodes, showing only "append" icon


    Hi,

    I have a tree view where I want to allow the user to move a node to a different parent node, taking with it all the tree below it.
    I want the following behavior when moving node X:
    • Allow drop of X on all nodes in the tree
    • Do not show 'before' and 'after' indicator - when hovering over a node only show the 'append' indicator
    • Don't allow drop of X on X
    • Don't allow drop of X on ancestor of X (or I could just ignore it on the drop event)
    • Don't allow drop of X on a descendant (node in sub-tree below X)
      • The node record has path field, which allow detection if T is below X or vice versa
    I tried the following config:
    Code:
            viewConfig:
            {
                plugins:
                {
                    ptype: "treeviewdragdrop",
                    containerScroll: true,
                    allowParentInsert: true,
                    allowContainerDrops: true,
                    appendOnly: true
                }
            }
    With appendOnly:true, The drop indicator is either green 'plus' or red 'no entry', which is how I want it, but it does not allow drop on leaves.
    With appendOnly:false, I also get drop indicator showing 'before' or 'after' when hovering over leaves, but I want to get the 'append' indicator (green 'plus').
    It looks like the view does not allow dropping X on any leaf. I don't see the point in this.

    I'd appreciate any suggestions on how to fix this behavior.

    Thanks,

    Thumbs up Fixed with override on getPosition in Ext.tree.ViewDropZone

    Fixed with override on getPosition in Ext.tree.ViewDropZone


    In Ext.tree.ViewDropZone, the getPosition() returns false with appendOnly:true for leaves.
    I fixed this by overriding this function and changing
    Code:
    noAppend = record.isLeaf(),
    to
    Code:
    noAppend = false,
