Example

The example looks as follows:

A double-line menu is displayed. When selecting a menu item, then its text is written to the status bar.

The XML layout definition is:

<page model="menue_02_dl_Adapter">
    <titlebar name="Double Line Menu">
    </titlebar>
    <dlmenu menuprop="menuData">
    </dlmenu>
    <header withdistance="false">
        <button name="Save">
        </button>
    </header>
    <pagebody>
    </pagebody>
    <statusbar withdistance="false">
    </statusbar>
</page>

The DLMENU control is positioned directly following the title bar. In its property menuprop, it holds a binding to the property menuData.

The Java code of the adapter is:

// This class is a generated one.

import com.softwareag.cis.server.Adapter;
import com.softwareag.cis.server.util.DLMenu;
import com.softwareag.cis.server.util.DLMenuSubItem;
import com.softwareag.cis.server.util.DLMenuTopItem;

public class menue_02_dl_Adapter
    extends Adapter
{
    // class >MyDLMenuSubItem<
    public class MyDLMenuSubItem extends DLMenuSubItem
    {
        public MyDLMenuSubItem(DLMenuTopItem topItem, String text)
        {
            super(topItem, text);
        }
        public void invoke()
        {
            outputMessage("S",getText() + " was invoked");
        }
    }
    // property >menuData<
    DLMenu m_menuData = new DLMenu();
    public DLMenu getMenuData() { return m_menuData; }

    /** initialisation - called when creating this instance*/
    public void init()
    {
        DLMenuTopItem top;
        MyDLMenuSubItem sub;
        top = new DLMenuTopItem(m_menuData,"File");
        sub = new MyDLMenuSubItem(top,"New...");
        sub = new MyDLMenuSubItem(top,"Save");
        sub = new MyDLMenuSubItem(top,"Save&nbsp;as...");
        sub = new MyDLMenuSubItem(top,"Remove");
        sub = new MyDLMenuSubItem(top,"Exit");
        top = new DLMenuTopItem(m_menuData,"Edit");
        sub = new MyDLMenuSubItem(top,"Undo");
        sub = new MyDLMenuSubItem(top,"Cut");
        sub = new MyDLMenuSubItem(top,"Copy");
        sub = new MyDLMenuSubItem(top,"Paste");
        top = new DLMenuTopItem(m_menuData,"Help");
        sub = new MyDLMenuSubItem(top,"Online Help");
        sub = new MyDLMenuSubItem(top,"About");
    }
}

There is an own class MyDLMenuSubItem which is subclassed from DLMenuSubItem in the package com.softwareag.cis.server.util. The main task of this own class is to overwrite the invoke() method and to put some logic inside.

Each menu node is represented by an object. Menu nodes of the top line are instances of the class DLMenuTopItem. Menu nodes of the second line are instances of the own class MyDLMenuSubItem.

All items are arranged inside the member m_menuData which is an instance of class DLMenu.

When the user clicks an item of the second line at runtime, the invoke() method of the corresponding item instance is called in the server.
