Double-click to select row -> inmethod grid

[Edvin Syse]

Hi,

I subclassed the AbstractGrid class to enable double-click to select a 
row instead of single-click, since it is handy to be able to click in a 
row to copy text etc, and then use double-click to select instead. 
Wouldn't this be a nice addition to the AbstractGrid class? Here is my 
quick/dirty implementation:

public class MyDataGrid extends DefaultDataGrid {
   /* Constructors */
   public MyDataGrid(String id, IModel model, List<IGridColumn> columns) {
       super(id, model, columns);
   }

   public MyDataGrid(String id, IDataSource dataSource, 
List<IGridColumn> columns) {
       super(id, dataSource, columns);
   }

   /* We want double-click to trigger ajax-call, not the default 
single-click */
   protected boolean disableRowClickNotifications() {
       return true;
   }

   /* Add ajax-behavior for double-click */
   protected void onRowPopulated(final WebMarkupContainer rowComponent) {
       super.onRowPopulated(rowComponent);

       rowComponent.add(new AjaxFormSubmitBehavior(getForm(), 
"ondblclick") {
           private static final long serialVersionUID = 1L;
          
           protected void onSubmit(AjaxRequestTarget target) {
           }

           protected void onError(AjaxRequestTarget target) {
           }

           protected void onEvent(AjaxRequestTarget target) {
               onRowDblClicked(target, rowComponent.getModel());
           }

           public CharSequence getCallbackUrl() {
               return super.getCallbackUrl() + "&column='+col+'";
           }

           protected IAjaxCallDecorator getAjaxCallDecorator() {
               return new AjaxCallDecorator() {
                   public CharSequence decorateScript(CharSequence 
script) {
                       return super.decorateScript("if 
(InMethod.XTable.canSelectRow(event)) { "
                               + "var col=(this.imxtClickedColumn || 
''); this.imxtClickedColumn='';" + script
                               + " }");
                   }
               };
           }
       });

   }

   /* Override this to implement the double-click action */
   protected void onRowDblClicked(AjaxRequestTarget target, IModel 
rowModel) {
   }
}
