CellTable vs DataGrid

[Alexander Orlov]

CellTable vs DataGrid — when to use which? DataGrid is for "large data sets" and CellTable for (kind of) smaller data sets. But is there a reason not to use the DataGrid Composite for all kinds of data sets? What would be the disadvantage, besides an (non-user-perceivable) init delay?

To my knowledge, both CellTable and DataGrid are for "large data sets" (as all the other Cell widgets; as opposed to Grid or FlexTable). The main (if not only) difference is that Datagrid has a fixed header/footer and a scrolling area for data (and thus is a RequiresResize), whereas CellTable generates a single grid with headers, data and footers (and thus has to be put inside a ScrollPanel to handle overflow, and then the headers and footers can scroll along with the data, and outside the viewport).

Where is the uibinder stuff for DataGrid defined?  I can't seem to find it and it doesn't appear in GWTDesigner.

Note that I'm using GWT 2.4.

I haven't ever used gwtdesigner. Search for gwt showcase, there you will find it.

There's nothing special, you have to initialize it in your Java code using either an @UiFactory or @UiField(provided=true).

As for DataGrid in GWT Designer, see http://code.google.com/p/google-web-toolkit/issues/list?can=1&q=DataGrid+designer
