| Block | | public interface Block extends Drawable(Code) | | A block is an arbitrary item that can be drawn (in Java2D space) within a
rectangular area, has a preferred size, and can be arranged by an
Arrangement manager.
|
| Method Summary | |
| public Size2D | arrange(Graphics2D g2)
Arranges the contents of the block, with no constraints, and returns
the block size.
Parameters:
g2 - the graphics device. | | public Size2D | arrange(Graphics2D g2, RectangleConstraint constraint)
Arranges the contents of the block, within the given constraints, and
returns the block size.
Parameters:
g2 - the graphics device.
Parameters:
constraint - the constraint (null not permitted). | | public Object | draw(Graphics2D g2, Rectangle2D area, Object params)
Draws the block within the specified area. | | public Rectangle2D | getBounds()
Returns the current bounds of the block. | | public String | getID()
Returns an ID for the block. | | public void | setBounds(Rectangle2D bounds)
Sets the bounds of the block. | | public void | setID(String id)
Sets the ID for the block. |
| arrange | | public Size2D arrange(Graphics2D g2)(Code) | | Arranges the contents of the block, with no constraints, and returns
the block size.
Parameters:
g2 - the graphics device. The size of the block. |
| arrange | | public Size2D arrange(Graphics2D g2, RectangleConstraint constraint)(Code) | | Arranges the contents of the block, within the given constraints, and
returns the block size.
Parameters:
g2 - the graphics device.
Parameters:
constraint - the constraint (null not permitted). The block size (in Java2D units, never null). |
| draw | | public Object draw(Graphics2D g2, Rectangle2D area, Object params)(Code) | | Draws the block within the specified area. Refer to the documentation
for the implementing class for information about the params
and return value supported.
Parameters:
g2 - the graphics device.
Parameters:
area - the area.
Parameters:
params - optional parameters (null permitted). An optional return value (possibly null). |
| getBounds | | public Rectangle2D getBounds()(Code) | | Returns the current bounds of the block.
The bounds. |
| getID | | public String getID()(Code) | | Returns an ID for the block.
An ID. |
| setBounds | | public void setBounds(Rectangle2D bounds)(Code) | | Sets the bounds of the block.
Parameters:
bounds - the bounds. |
| setID | | public void setID(String id)(Code) | | Sets the ID for the block.
Parameters:
id - the ID. |
