Class VectorToButtons

java.lang.Object
  |
  +--com.objectwave.viewUtility.VectorToButtons

public class VectorToButtons
extends java.lang.Object

Provides the ability to create a vector of buttons from a vector of data. The method getButtons() will return the buttons generated, and getPanel() will return the buttons contained in a JPanel using a vertically-oriented GridLayout. Note that the buttons and the panel will automatically update with calls to the various setXxx() methods. The same panel will always be returned for a given instance of this class, while the buttons array will change if and only if the data vector is changed. Displaying Labels:

The labels for the buttons can be specified if three different ways. A vector of strings can be provided via the setLabels() method, a StringifyIF instance can be provided, or the toString() value of each data element can be used. If a vector of strings is provided, then that will be used over all other methods. Otherwise, if a stringifier is defined, then it will be used. If all else failed the toString() values are used.

Customizing the Buttons' Appearance
The font of all of the buttons can be specified simply by calling setFont(). Additionally, the layout can be modified by calling getPanel().setLayout(someLayoutManager). This should be followed by getPanel().revalidate() if the panel may currently be visible.

Specifying Button Behavior
A common behavior can be associated with all of the buttons by calling setAction() with some ActionIF object. This interface's single method, public void performAction(Object), is passed the data element associated with the button that was clicked. This single ActionIF object is applied to all buttons. If this is not desired for a given button, then simply call removeListener(int), passing the index of the given button.
