DrawablePanel | public DrawablePanel()(Code) | | |
getMinimumSize | public Dimension getMinimumSize()(Code) | | If the minimum size has been set to a non-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.
the value of the minimumSize property See Also: DrawablePanel.setMinimumSize See Also: javax.swing.plaf.ComponentUI |
getPreferredSize | public Dimension getPreferredSize()(Code) | | If the 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.
the value of the preferredSize property See Also: DrawablePanel.setPreferredSize See Also: javax.swing.plaf.ComponentUI |
isOpaque | public boolean isOpaque()(Code) | | Returns true if this component is completely opaque.
An opaque component paints every pixel within its rectangular bounds. A
non-opaque component paints only a subset of its pixels or none at all,
allowing the pixels underneath it to "show through". Therefore, a
component that does not fully paint its pixels provides a degree of
transparency.
Subclasses that guarantee to always completely paint their contents should
override this method and return true.
true if this component is completely opaque See Also: DrawablePanel.setOpaque |
paintComponent | protected void paintComponent(Graphics g)(Code) | | Calls the UI delegate's paint method, if the UI delegate is
non-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 See Also: DrawablePanel.paint See Also: javax.swing.plaf.ComponentUI |
