Multi edit in Menu options [message #1565830]

Hi

I have placed the Multi Edit on Menu options that we get when we right click on the column of the nat table.

It works correctly, my question is:

How shall I grey out the menu option for Multi edit on the basis of whether the cells are editable or not.

I have gone through the code of Nat Table and there is an iterator that calculates the cell Size

for (Iterator<ILayerCell> iterator = editCells.iterator(); iterator.hasNext(); ) {
ILayerCell layerCell = iterator.next();
LabelStack labelStack = layerCell.getConfigLabels();
IEditableRule editableRule = configRegistry.getConfigAttribute(
EditConfigAttributes.CELL_EDITABLE_RULE,
DisplayMode.EDIT, labelStack.getLabels());
if (!editableRule.isEditable(layerCell, configRegistry)) {
iterator.remove();
}
}

But the problem is how can I invoke this before pressing F2 or how can I get to know that the Multi Edit will not be invoked so that on right click I can grey out the Multi Edit option.

Regards
Ambuj

Hi Ambuj,

If you use NatTable IMenuItemProvider to add the multi-edit menu item to the menu, you can use the following code:


new IMenuItemProvider() {

   @Override
   public void addMenuItem(NatTable natTable, Menu popupMenu) {
		
      final MenuItem myMenuItem = new MenuItem(popupMenu, SWT.PUSH);
      myMenuItem.setText("Some Text");
      myMenuItem.addSelectionListener(new SelectionAdapter() {
         @Override
         public void widgetSelected(SelectionEvent event){

            //Do your stuff

         }
      });
								
      popupMenu.addMenuListener(new MenuAdapter() {
         @Override
         public void menuShown(MenuEvent e) {

            myMenuItem.setEnabled(condition);
         }
      });
}

Hope it Helps

With the current version of NatTable the solution above is a way to solve your requirement.

With NatTable 1.2.0 you will be able to register an IMenuItemState to grey out or hide menu items.
