    <p>I am using the <code>ComboBox</code> in LWUIT. My code goes like this.</p> <pre><code>public Locations(String name, int X, int Y) { Name = name; xLocation = X; yLocation = Y; } </code></pre> <p>I have made a list of <code>Locations</code></p> <pre><code>private List getLocations() { List list = new List(); list.addItem(new Locations("Landmark1", 23, 40)); list.addItem(new Locations("Landmark3", 24, 40)); list.addItem(new Locations("Landmark4", 25, 40)); list.addItem(new Locations("Landmark6", 26, 40)); return list; } </code></pre> <p>Then made the ComboBox contain the List.</p> <pre><code>comboBox_Locations = new ComboBox(getLocations().getModel()); </code></pre> <p>Now, my problem is that how can I display only the Name of the Location on the ComboBox? I know I can make a list of strings of the Name of the Location like this: </p> <pre><code>private List getLocations() { List list = new List(); list.addItem(new Locations("Landmark1", 23, 40).Name); list.addItem(new Locations("Landmark3", 24, 40).Name); list.addItem(new Locations("Landmark4", 25, 40).Name); list.addItem(new Locations("Landmark6", 26, 40).Name); return list; } </code></pre> <p>But when I get the <code>selectedItem</code>, it only gets the Name and I cannot get the coordinates. What I wanted to do is to get the class like this: </p> <pre><code>Object item = comboBox_Locations.getSelectedItem(); if (item.getClass() == Locations.class) { String Name = ((Locations)item).Name.toString(); int xCoords = ((Locations)item).getX(); int yCoords = ((Locations)item).getY(); } </code></pre> <p>So that I can use the xCoords and yCoords.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
