Disable Functions

Spreadsheet provides API to disable its functions. The API can be very useful when you implement your user permission features. In the example application below, since we disable functions including "Add a Sheet", "Delete a Sheet", and "Copy a Sheet", you can see the corresponding menu items are disabled (in grey color).

To achieve this, simply call Spreadsheet

package org.zkoss.zss.essential.advanced.customization;

import org.zkoss.zk.ui.Component;
import org.zkoss.zk.ui.event.CheckEvent;
import org.zkoss.zk.ui.select.SelectorComposer;
import org.zkoss.zk.ui.select.annotation.*;
import org.zkoss.zss.ui.*;

/**

@SuppressWarnings("serial")
public class DisableActionsComposer extends SelectorComposer<Component> {

	@Wire
	private Spreadsheet ss;
	
	@Listen("onCheck = #add")
	public void disableAdd(CheckEvent event) {
		ss.disableUserAction(AuxAction.ADD_SHEET, !event.isChecked());
	}
...
}

Except sheet operations, you can also disable functions on the toolbar and the context menu. Take a look at AuxAction for a complete list of functions you can disable.
