| 48 | * Provides the basic look and feel for a <code>JOptionPane</code>. | ||
| 49 | * <code>BasicMessagePaneUI</code> provides a means to place an icon, | ||
| 50 | * message and buttons into a <code>Container</code>. | ||
| 51 | * Generally, the layout will look like:<p> | ||
| 52 | * <pre> | ||
| 53 | * ------------------ | ||
| 54 | * | i | message | | ||
| 55 | * | c | message | | ||
| 56 | * | o | message | | ||
| 57 | * | n | message | | ||
| 58 | * ------------------ | ||
| 59 | * | buttons | | ||
| 60 | * |________________| | ||
| 61 | * </pre> | ||
| 62 | * icon is an instance of <code>Icon</code> that is wrapped inside a | ||
| 63 | * <code>JLabel</code>. The message is an opaque object and is tested | ||
| 64 | * for the following: if the message is a <code>Component</code> it is | ||
| 65 | * added to the <code>Container</code>, if it is an <code>Icon</code> | ||
| 66 | * it is wrapped inside a <code>JLabel</code> and added to the | ||
| 67 | * <code>Container</code> otherwise it is wrapped inside a <code>JLabel</code>. | ||
| 68 | * <p> | ||
| 69 | * The above layout is used when the option pane's | ||
| 70 | * <code>ComponentOrientation</code> property is horizontal, left-to-right. | ||
| 71 | * The layout will be adjusted appropriately for other orientations. | ||
| 72 | * <p> | ||
| 73 | * The <code>Container</code>, message, icon, and buttons are all | ||
| 74 | * determined from abstract methods. | ||
