Question

I would like to develop in GWT a vertical menu similar to the one found on http://gwt.google.com/samples/Showcase/Showcase.html (the left blue menu which first section is “Widgets”).

Since it’s a GWT showcase, one can assume that left menu is a GWT widget, but which one ?

I have browsed every example and none of them looks like that menu. Any guess ?

Answer 1

It’s the CellTree widget!

A demo is actually inside the showcase: CellTree, but in the example, it has a different style applied:

CellTree.Resources res = GWT.create(CellTree.BasicResources.class);
CellTree.Resources res = GWT.create(CellTree.BasicResources.class);
    cellTree = new CellTree(
        new ContactTreeViewModel(selectionModel), null, res);

(this stlyes makes the +/- buttons and lets it look like a regular tree)

If you don’t apply this style the Cell Tree looks like the left menu.
