I'm mapping a file tree to a QxTree. But i find myself wanting to create
my own Tree object and using it and the QxTree in tandem to do what i
want. This is because for every tree node i want to save the filename,
path and children. Or sometimes i want to change the apperance of a
specific node. Also when i just collapse a QxTree it only works if i
save all the nodes in a seperate array and collapse them all reversed -
like this:
function collapse(nodes) {
for (var i=1; i <= nodes.length; i++)
nodes[nodes.length - i].setOpen(false);
}
otherwise i get display errors.
But this is all ugly. So to sum it up: Is there an elegant way to
collapse a QxTree and save extra information for every node?
First, why not just use the open and close methods of each folder
instance. Second, you can save any information you like to an javascript
instance. Just do something like:
myTreeFolder._someInfo = "foo";
Also there is a nice qooxdoo interface for this type of data:
myTreeFolder.setUserData("someInfo", "foo");
alert(myTreeFolder.getUserData("someInfo"));
Hope this helps.
