ListGrid doesn't want to set the width of the delete-button column

[lnplnp]

Some informations :

• SmartClient Version: v8.2p_2012-05-23/LGPL Development Only (built 2012-05-23)
• Google Chrome Version 23.0.1271.95 m
• GWT 2.4.0
• Eclipse Version: Indigo Service Release 2, Build id: 20120216-1857
• SmartGWT 3.1

On a ListGrid, when you enable to remove a record there is a cross image stand on each record line.
Is it possible de resize this column ?

    for (ListGridField field : listGrid.getFields()) {
      System.out.println("'" + field.getName() + "'");
    }

When I ask for the list of fields of listGrid it give me a list of column name then a column whose name is "$54h"... I think it is the name for the delete button column.

But it seems that this code :

    for (ListGridField field : listGrid.getFields()) {
      field.setWidth("100%");
    }
    listGrid.getField("$54h").setWidth(60);

does not produce what I want : means my delete-button column is not 60px width.

Does anyone understand why ?

This is what I get have :


More source code :

    listGrid = new ListGrid();
    listGrid.setCanRemoveRecords(false);
    listGrid.setCanEdit(false);
    listGrid.setAutoFitFieldsFillViewport(true);
    listGrid.setAutoFitFieldWidths(true);
    listGrid.setWidth100();
    listGrid.setHeight100();
    listGrid.setShowAllRecords(true);
    listGrid.setAlternateRecordStyles(true);
    listGrid.setEditEvent(ListGridEditEvent.CLICK);
    listGrid.setShowRecordComponents(true);
    listGrid.setShowRecordComponentsByCell(true);
    listGrid.setShowHeaderContextMenu(false);
    listGrid.setShowHeaderMenuButton(false);

    setFieldsWidth();

  private void setFieldsWidth() {
    for (ListGridField field : listGrid.getFields()) {
      field.setWidth("100%");
    }

    int column_width = 60;
    setFieldWidth("COL_NAME1", column_width);
    setFieldWidth("COL_NAME2", column_width);
    setFieldWidth("COL_NAME3", column_width);
    setFieldWidth("COL_NAME4", column_width);
    setFieldWidth("COL_NAME5", column_width);
    // Taille de la colonne contenant le bouton de suppression
    setFieldWidth("$54h", 60);
  }

  private void setFieldWidth(String name, int width) {
    if (null != listGrid.getField(name)) {
      listGrid.getField(name).setWidth(width);
    }
  }
