Question

This is a GWT question.

I need to create a hierarchical view of a data set. Let me describe what this hierarchical view is supposed to be:

1. Lay down a rectangle that is 640 by 480 pixels on your screen.
2. Now embed 4 rectangles inside the rectangle from the previous step.
   • The 4 rectangles shall evenly take up the space from the enclosing rectangle.
3. Continue recursively embedding 4 rectangles inside each 4 rectangle…
4. So on and so forth until a stop condition (like stop recursing at level N).

I plan on doing this with GWT’s CellTable. I know how to make a CellTable out of the various out-of-the-box Cell’s (what I mean to say is: all the classes that implement the Cell interface ).

But I can’t figure out how to make a CellTable of Widgets… or a CellTable of CellTables. I guess my question boils down to… How would you make a new Cell type that is: WidgetCell or CellTableCell?

UPDATE:

I found an answer that describes how to make a Cell out of a Widget: how-can-i-put-a-widget-in-a-celltable-cell

Given the above answer, is my original idea of making a CellTable out of CellTables practically feasible? Is there a more elegant solution? Am I on the right-track?

Answer 1

CellTables do not support widgets. Grid or FlexTable might work better for you, since they do accept widgets – you could make a Grid of CellTables, for instance. Unfortunately, there is no built-in solution that accepts widgets and provides paging.
