 |
|
Is there anyway to automatically fill a jdbtree from a dataset? I'm confused
by the docs as to whether it will only work as a picklist/lookup or if it
can be filled also. If so, how does the tree know how to display leafs and
hierarchies? Of course I can do it manually but trying avoid that. I also
posted about looking for a treetable fillable by dataset but got no
response.

I haven't used JdbTree. However, in samples/dbswing/htmlviewer,
the dialog uses the component. You may have already looked at
this. If not, TreeModelMaker shows how to populate the
model. The example is filling the tree model manually,
but since the table (nodeData) could be represented by
a DataSet, you could use a dataset, but you'd
have to massage it from a table to a graph representation.
Modify TreeModelMaker to use a dataset instead of the
hand-coded nodeData. Or extend JdbTree, and provide a
"setModel(DataSet modelDataset)", and do the massaging there.
In such a scheme, there would be two datasets associated with
the tree component: 1) that which provides the data for
the tree model, and 2) that which provides is bound to
the navigational feature of the JdbTree.
Seems a bit complicated, and I'm sure I haven't covered
all the details.

That means, do not send email directly to me.
Thank you.
