Re: Select All Behavior on CheckboxCell

Just add a ClickHandler to your button that does this when clicked:

for (MyProxy proxy: dataProvider.getList()) {

   selectionModel.setSelected(proxy, true);

}

where selectionModel is a MultiSelectionModel and dataProvider is your table's data provider.

Your checkBoxes will be checked/unchecked in sync with the selectionModel if you set it up like this:

Column<MyProxy, Boolean> checkColumn = new Column<MyProxy, Boolean>(new CheckboxCell(true)) {

   @Override

   public Boolean getValue(MyProxy object) { 

      return selectionModel.isSelected(object);

   }

}; 

checkColumn.setFieldUpdater(new FieldUpdater<MyProxy, Boolean>() {
   public void update(int index, MyProxy object, Boolean value) { 
      selectionModel.setSelected(object, value);

   }

});

Hi Guys,

I have a CellTable with a "com.google.gwt.cell.client.CheckboxCell" column, I would like to implement a "select all/deselect all" behavior when the user clicks a specific button.

What is the best way to implements this?

Thanks
