must be
detached before calling RowRenderer.render(org.zkoss.zul.Row, T, int)
.
Default: true.
If this interface is not specified, this flag is assumed
to be specified.
If you don't specify this flag, the implementation of
RowRenderer.render(org.zkoss.zul.Row, T, int)
must be aware of the existence of
the first cell (of the passed row).
Row newRow(Grid grid)
Row
that will be attached to grid.
The created component will be passed to RowRenderer.render(org.zkoss.zul.Row, T, int)
to append the required information to show a row of the data.
Note: remember to invoke AbstractComponent.applyProperties()
to initialize
the properties, defined in the component definition, properly.
If null is returned, the default row is created as follow.
final Row row = new Row();
row.applyProperties();
return row;
Note: DO NOT call AbstractComponent.setParent(org.zkoss.zk.ui.Component)
.

RowRenderer.render(org.zkoss.zul.Row, T, int)
is not called yet.
Notice that this callback shall generate an empty cell,
rather than showing the data retrieved from the model.
The showing of the data from model shall be done
in RowRenderer.render(org.zkoss.zul.Row, T, int)
.
If null is returned, the default cell is created as follows.
final Label cell = new Label();
cell.applyProperties();
return cell;
Note: remember to invoke Component.applyProperties()
to
initialize the properties, defined in the component definition, properly,
if you create an instance instead of returning null.
Note: DO NOT call AbstractComponent.setParent(org.zkoss.zk.ui.Component)
.
Note: DO NOT call Component.setParent(org.zkoss.zk.ui.Component)
.
Don't create cells for other columns.
