- All Implemented Interfaces:
- javax.accessibility.Accessible, java.awt.image.ImageObserver, java.awt.MenuContainer, java.io.Serializable
- public class ComboArea
- extends javax.swing.JPanel
Combines the idea of a combobox with a text area so that multiline entries can be displayed properly. Basically takes a JCombobox, (or in this case a SteppedComboBox that allows us to control the popup window that appears), butchers out the JTextField editor while retaining the button and the data model, then uses a JTextArea for the editor instead.
- Version:
- 2.3

ignore
private boolean ignore
- Should the listener ignore any change events fired (most likely as a result of the listener in the first place).
combobox
private SteppedComboBox combobox
- The combobox we are going to utilize.
text_area
private SmarterTextArea text_area
- The text area involved. Not quite a JTextArea, the smarter part is that is allows coloring contrary to the UIManager settings.
ComboArea
public ComboArea(java.lang.String text,
java.awt.Dimension label_size)
- Create a new ComboArea demarked by a particular label. The label is given here so that it fits nicely with the text area and button.
add
public void add(java.lang.Object item)
- Add an element to our combobox model. Remember to tell the listeners to ignore this action unless you want an infinite loop.
clear
public void clear()
- Clear the combobox model.
getText
public java.lang.String getText()
- Retrieve the text currently displayed in the text area.
getTextComponent
public javax.swing.text.JTextComponent getTextComponent()
- Retrieve a reference to the text area.
setSelectedItem
public void setSelectedItem(java.lang.Object item)
- Change the selected item in the combobox to the one given. If such an object doesn't exist in the model, ignore it. Notice that this time we don't ignore, as we want a selection to update the text field.
setText
public void setText(java.lang.String text)
- Set the text shown in the text area to the value provided. Note that this has no effect on the combobox, nor will this value be stored in the model.
