Method Detail
-
getDrawable
public org.pentaho.reporting.libraries.resourceloader.factory.drawable.DrawableWrapper getDrawable()
-
setDrawableAsRawObject
public void setDrawableAsRawObject(Object o)
-
setDrawable
public void setDrawable(org.pentaho.reporting.libraries.resourceloader.factory.drawable.DrawableWrapper drawable)
-
getPreferredSize
public Dimension getPreferredSize()
If thepreferredSize
has been set to a non-null
value just returns it. If the UI delegate'sgetPreferredSize
method returns a nonnull
value then return that; otherwise defer to the component's layout manager.- Overrides:
getPreferredSize
in classJComponent
- Returns:
- the value of the
preferredSize
property - See Also:
JComponent.setPreferredSize(java.awt.Dimension)
,ComponentUI
-
getMinimumSize
public Dimension getMinimumSize()
If the minimum size has been set to a non-null
value just returns it. If the UI delegate'sgetMinimumSize
method returns a non-null
value then return that; otherwise defer to the component's layout manager.- Overrides:
getMinimumSize
in classJComponent
- 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 classJComponent
- Returns:
- true if this component is completely opaque
- See Also:
JComponent.setOpaque(boolean)
-
paintComponent
protected void paintComponent(Graphics g)
Calls the UI delegate's paint method, if the UI delegate is non-null
. We pass the delegate a copy of theGraphics
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 inGraphics
. For example, you should not alter the clipRectangle
or modify the transform. If you need to do these operations you may find it easier to create a newGraphics
from the passed inGraphics
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 inGraphics
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 classJComponent
- Parameters:
g
- theGraphics
object to protect- See Also:
