Adding items to default contextMenu in ListGrid

[pferraiolo]

I would like to add a few items to the headerContextMenu in the ListGrid.

I know that getHeaderContextMenu(fieldnum) is used to populate the default items. What would be the correct method for extending this list?

A short example would be greatly appreciated.

Thanks,
paul

Here is an example that works for me. I wanted to add a menu item separator followed by an option to download the grid contents as a csv file.

private final ListGrid itemGrid = new ListGrid()        
// add a "download to Excel" option to the standard grid header menu
{
   protected MenuItem[] getHeaderContextMenuItems(final Integer fieldNum) {
       final MenuItem[] items = super.getHeaderContextMenuItems(fieldNum);
       MenuItem customItem = new MenuItem("Download to Excel");
       customItem.setIcon("../customimages/excel.png");
       customItem.addClickHandler(new com.smartgwt.client.widgets.menu.events.ClickHandler() {
           public void onClick(MenuItemClickEvent event) {
               exportData();       
           }
       });
       MenuItem[] newItems = new MenuItem[items.length + 2];
       for (int i = 0; i < items.length; i++) {
           MenuItem item = items[i];
           newItems[i] = item;
       }
       newItems[items.length] = new MenuItemSeparator();
       newItems[items.length+1] = customItem;
       return newItems;
    }
};

Thanks Jay.

I was able to translate this general method to .js easily enough.
