Grid Plugins

Additions to the grids like the Row Numberer, checkboxes, Row Expander are added as plugins to the Grid.

Adding Row Expander:

  1: XTemplate tpl = XTemplate.create("<p><b>Company:</b> {name}</p><br><p><b>Summary:</b> {desc}</p>");
  2: RowExpander expander = new RowExpander();
  3: expander.setTemplate(tpl);  

and then we need to add the plugin to the grid. We cannot apply a rowExpander to a Summary Grid.


The XTemplate contains the information that has to be displayed when the “+” is clicked.

Adding Row Numberer:

  1: RowNumberer r = new RowNumberer();
  2: List<ColumnConfig> configs = new ArrayList<ColumnConfig>();
  3: configs.add(r);  

and then add the plugin to the grid.

Adding Checkboxes:
  1: CheckBoxSelectionModel sm = new CheckBoxSelectionModel();
  2: configs.add(sm.getColumn());

Add the plugin to the grid

Adding the grid plugin will provide automatic reorganization when the grid store values have changed.
