BasicOptionPaneUI

public class BasicOptionPaneUI extends OptionPaneUI
Provides the basic look and feel for a JOptionPane. BasicMessagePaneUI provides a means to place an icon, message and buttons into a Container. Generally, the layout will look like:

------------------
| i | message |
| c | message |
| o | message |
| n | message |
------------------
| buttons |
|________________|
icon is an instance of Icon that is wrapped inside a JLabel. The message is an opaque object and is tested for the following: if the message is a Component it is added to the Container, if it is an Icon it is wrapped inside a JLabel and added to the Container otherwise it is wrapped inside a JLabel.

The above layout is used when the option pane's ComponentOrientation property is horizontal, left-to-right. The layout will be adjusted appropriately for other orientations.

The Container, message, icon, and buttons are all determined from abstract methods.

Methods Summary
protected voidaddButtonComponents(java.awt.Container container, java.lang.Object[] buttons, int initialIndex)
Creates the appropriate object to represent each of the objects in buttons and adds it to container. This differs from addMessageComponents in that it will recurse on buttons and that if button is not a Component it will create an instance of JButton.

	if (buttons != null && buttons.length > 0) {
	    boolean            sizeButtonsToSame = getSizeButtonsToSameWidth();
	    boolean            createdAll = true;

protected voidaddIcon(java.awt.Container top)
Creates and adds a JLabel representing the icon returned from getIcon to top. This is messaged from createMessageArea
