Constructor Detail

### DrawablePanel

    public DrawablePanel()

  Creates a new instance.

Method Detail

### getDrawable

    public Drawable getDrawable()

  Returns the drawable item.

  Returns:
    The drawable item.

### setDrawable

    public void setDrawable(Drawable drawable)

  Sets the drawable item.

  Parameters:
    `drawable` - the drawable item.

### getPreferredSize

    public java.awt.Dimension getPreferredSize()

  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.

  Overrides:
    `getPreferredSize` in class `javax.swing.JComponent`
  Returns:
    the value of the `preferredSize` property
  See Also:
    `JComponent.setPreferredSize(java.awt.Dimension)`, `ComponentUI`

### getMinimumSize

    public java.awt.Dimension getMinimumSize()

  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.

  Overrides:
    `getMinimumSize` in class `javax.swing.JComponent`
  Returns:
    the value of the `minimumSize` property
  See Also:
    `JComponent.setMinimumSize(java.awt.Dimension)`, `ComponentUI`

### isOpaque

    public boolean isOpaque()

  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.

  Overrides:
    `isOpaque` in class `javax.swing.JComponent`
  Returns:
    true if this component is completely opaque
  See Also:
    `JComponent.setOpaque(boolean)`

### paintComponent

    protected void paintComponent(java.awt.Graphics g)

  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.

  Overrides:
    `paintComponent` in class `javax.swing.JComponent`
  Parameters:
    `g` - the `Graphics` object to protect
  See Also:
    `JComponent.paint(java.awt.Graphics)`, `ComponentUI`
