Re: DataGrid vs CellTable

Ooops, missed your second question, about the parent widget.  Here is the path:
FlowPanel -> WidgetList -> DataGrid

Your comments above about the contraints are what made me ask my question in the first place.  I even set the size of the DataGrid to 100% on the hunch that that would meet your rule that it must be "explicitly sized".  Granted,  I am not sizing the columns, which you also mention.  Regardless, if my understanding is correct, in order to use DataGrid and CellTable interchangeably, I would have to make some changes.

So does this means they cannot be used interchangeably?  For instance, I have a table.  When I define it as a "CellTable", it works fine.  But when I simple change it to a DataGrid ( no other changes ), it does not work.

"Does not work" is not really helpful.

 

Your comments suggest that I need to do some extra steps for DataGrid.  I am just trying to confirm my understanding.  Thanks

• CellTable example:

private AbstractCellTable<FacilityModel> facilityTable;
facilityTable = new CellTable<FacilityModel>();

• DataGrid example:

private AbstractCellTable<FacilityModel> facilityTable;
facilityTable = new DataGrid<FacilityModel>();

As stated above, the ONLY difference is the creation statement, which I highlighted in yellow above.  Thanks.

DataGrid and CellTable both display data in similar ways; but DataGrid has fixed column headers with scrollable content (have a look at the Showcase: http://gwt.google.com/samples/Showcase/Showcase.html#!CwCellTable vs. http://gwt.google.com/samples/Showcase/Showcase.html#!CwDataGrid )

Note that DataGrid comes with a few constraints: it's a RequiresResize so it must be put inside a ProvidesResize widget or be explicitly sized, and it has fixed-width columns.

So, which is the parent widget of facilityTable?
