TreeGrid and CellEditor

[A.Rothe]

Hi,

I have a TreeGrid and have added CellEditors to two columns. Both columns are not the tree column (a date and a comment). The tree should not support editing on every row, so how I can prevent the rendering of the editor on some rows? the CellEditor only holds a column/row number, how I can get the ModelData instance to check the possibility of editing in this row?

Thanks
André

You could listen to the BeforeEdit event and cancel that if that specific cell should not be edited.

I have found it:

tree.addListener(Events.BeforeEdit, new BeforeEditListener());

private class BeforeEditListener implements Listener<GridEvent<ModelData>> {

   public void handleEvent(GridEvent<ModelData> event) {
      ModelData model = event.getModel();

      // check, if the model is on the right place to edit
      // use the store
   }
}

The "tree" should also an instance of EditorTreeGrid. Don't forget to set the clicksToEdit:

tree.setClicksToEdit(ClicksToEdit.TWO);
