Method Summary | |

DrawableWrapper | getDrawable() |
Dimension | getMinimumSize()
If the minimum size has been set to a non- null value just
returns it. |
Dimension | getPreferredSize()
If the preferredSize has been set to a non-null
value just returns it. |
boolean | isOpaque()
Returns true if this component is completely opaque.
|
protected void | paintComponent(Graphics g)
Calls the UI delegate's paint method, if the UI delegate is
non- null . |
void | setDrawable(DrawableWrapper drawable) |
void | setDrawableAsRawObject(Object o) |
null
value just
returns it. If the UI delegate's getMinimumSize
method
returns a non-null
value then return that; otherwise defer to
the component's layout manager.
Returns: the value of the minimumSize
property

preferredSize
has been set to a non-null
value just returns it. If the UI delegate's getPreferredSize
method returns a non null
value then return that; otherwise
defer to the component's layout manager.
Returns: the value of the preferredSize
property

Returns: true if this component is completely opaque

null
. We pass the delegate a copy of the
Graphics
object to protect the rest of the paint code from
irrevocable changes (for example, Graphics.translate
).
If you override this in a subclass you should not make permanent changes to
the passed in Graphics
. For example, you should not alter the
clip Rectangle
or modify the transform. If you need to do
these operations you may find it easier to create a new
Graphics
from the passed in Graphics
and
manipulate it. Further, if you do not invoker super's implementation you
must honor the opaque property, that is if this component is opaque, you
must completely fill in the background in a non-opaque color. If you do not
honor the opaque property you will likely see visual artifacts.
The passed in Graphics
object might have a transform other
than the identify transform installed on it. In this case, you might get
unexpected results if you cumulatively apply another transform.
Parameters: g the Graphics
object to protect
