Hi everyone!
First of all, thanks for helping 2 french wicket padawan developers :-)
We tried to make a Tree for our wicket application, but we encountered a
problem.
The tree is created, with simple file names, but we can't redirect the click
to the download link, and that's a big problem. We saw that if we try to add
an ExternalLink to the Tree, it works (see comments in code).
This is the source (simplified for the post):
LinkTree tree = new LinkTree( "tree", new DefaultTreeModel( root ) ) {
@Override
protected Component newNodeComponent( String id, IModel
model ) {
return new LinkIconPanel( id, model, this ) {
@Override
protected Component
newContentComponent( String componentId, BaseTree
tree, IModel model ) {
Object obj = ( (
DefaultMutableTreeNode )model.getObject()
).getUserObject();
if( obj instanceof AbstractLink
) {
// return new
ExternalLink( componentId, "http://www.google.fr";,
"Example ExternalLink" );
DownloadLink dl = new
DownloadLink( componentId, new File(
"toto-example.png" ), "Example DownloadLink" );
return dl;
}
return new Label( componentId,
model.getObject().toString() );
}
};
}
};
As you can see, we override the method newNodeComponent(.,.) for allowing
overriding the method newContentComponent(.,.,.). The problem is that we
can't see the name of the file nor the DownloadLink, even if we can redirect
a click on an ExternalLink given to the LinkTree.
We hope our explanations were clear, and will permit you helping us.
