[2.0rc1/2.0.1] TreePanel: Dropping onto a Leaf Node

[Chroder]

Whenever any node is set as a leaf, you can't append nodes to it via drag+drop.

I think this must be a mistake since there are config options 'allowChildren' and 'allowDrop' to control such behavior.

Changing this line of Ext.tree.TreeDropZone in getDropPoint() (removing the isLeaf check) fixes it:

var noAppend = tn.allowChildren === false || tn.isLeaf();

[rodiniz]

I think this is a bug also... I was almost putting it as a feature request..hope to see it fixed soon.

I don't think this is a bug. By declaring something as a leaf you're saying it can't have any children. If you want it to have a children, don't declare it as a leaf.

[rodiniz]

But on a dynamic tree you can't transform any non leaf nodes into a leaf node.
And that's not god..If a node doesn't have any children when its loaded that shouldn't mean it can't have any children always.

[evant]

Just because the node is at the lowest level of the tree, doesn't necessarily make it a leaf. A leaf node is only created if you specify it in the config for the node. If there's the possibility data might be added under it, then don't specify that property.

[rodiniz]

If i remove all children from a node, dragging then to another node,it becomes a leaf and doesn't accept children any more...

for Ext 1.1.1 find in ext-all.js:

var H=J.allowChildren===false||J.isLeaf();

and replase on:

var H=J.allowChildren===false;

[kylegohn]

If I add the following to my ext-all.js with the 1.1 version. My leaf does accept children however, the icon for the node remains a leaf and not a folder. Do you know how I would go about declaring the image of the said node to automatically have the folder icon?


var H=J.allowChildren===false;

我的办法是重载Ext.data.Node，添加一个setLeaf方法，然后在tree的append事件中把节点的leaf都设为false。

Ext.override(Ext.data.Node, {
    setLeaf: function(value){
    this.leaf = value;
}
}); 

this.on('append',function(tree,p,n,index){
    n.setLeaf(false);
});
