javax.swing
class CellRendererPane
- All Implemented Interfaces:
- MenuContainer, ImageObserver, Serializable, Accessible
-
Most common way to construct:
-
CellRendererPane rendererPane = new CellRendererPane();
Based on 11 examples
public class CellRendererPane
extends Container
implements Accessible
This class is inserted in between cell renderers and the components that
use them. It just exists to thwart the repaint() and invalidate() methods
which would otherwise propagate up the tree when the renderer was configured.
It's used by the implementations of JTable, JTree, and JList. For example,
here's how CellRendererPane is used in the code the paints each row
in a JList:
cellRendererPane = new CellRendererPane();
...
Component rendererComponent = renderer.getListCellRendererComponent();
renderer.configureListCellRenderer(dataModel.getElementAt(row), row);
cellRendererPane.paintComponent(g, rendererComponent, this, x, y, w, h);
A renderer component must override isShowing() and unconditionally return
true to work correctly because the Swing paint does nothing for components
with isShowing false.
Warning:
Serialized objects of this class will not be compatible with
future Swing releases. The current serialization support is
appropriate for short term storage or RMI between applications running
the same version of Swing. As of 1.4, support for long term storage
of all JavaBeansTM
has been added to the java.beans
package.
Please see {@link java.beans.XMLEncoder}.

accessibleContext
protected AccessibleContext accessibleContext
-
CellRendererPane
public CellRendererPane()
-
Construct a CellRendererPane object.
addImpl
protected void addImpl(Component x,
Object constraints,
int index)
-
If the specified component is already a child of this then we don't
bother doing anything - stacking order doesn't matter for cell
renderer components (CellRendererPane doesn't paint anyway).<
- Overrides:
addImpl
in class Container
- Parameters:
x
constraints
index
getAccessibleContext
public AccessibleContext getAccessibleContext()
-
Gets the AccessibleContext associated with this CellRendererPane.
For CellRendererPanes, the AccessibleContext takes the form of an
AccessibleCellRendererPane.
A new AccessibleCellRendererPane instance is created if necessary.
- Overrides:
getAccessibleContext
in class Component
- Returns:
- an AccessibleCellRendererPane that serves as the
AccessibleContext of this CellRendererPane
invalidate
public void invalidate()
-
Overridden to avoid propagating a invalidate up the tree when the
cell renderer child is configured.
- Overrides:
invalidate
in class Container
paint
public void paint(Graphics g)
-
Shouldn't be called.
- Overrides:
paint
in class Container
- Parameters:
g
paintComponent
public void paintComponent(Graphics g,
Component c,
Container p,
int x,
int y,
int w,
int h)
-
Calls this.paintComponent(g, c, p, x, y, w, h, false).
- Parameters:
g
c
p
x
y
w
h
paintComponent
public void paintComponent(Graphics g,
Component c,
Container p,
int x,
int y,
int w,
int h,
boolean shouldValidate)
-
Paint a cell renderer component c on graphics object g. Before the component
is drawn it's reparented to this (if that's necessary), it's bounds
are set to w,h and the graphics object is (effectively) translated to x,y.
If it's a JComponent, double buffering is temporarily turned off. After
the component is painted it's bounds are reset to -w, -h, 0, 0 so that, if
it's the last renderer component painted, it will not start consuming input.
The Container p is the component we're actually drawing on, typically it's
equal to this.getParent(). If shouldValidate is true the component c will be
validated before painted.
- Parameters:
g
c
p
x
y
w
h
shouldValidate
paintComponent
public void paintComponent(Graphics g,
Component c,
Container p,
Rectangle r)
-
Calls this.paintComponent() with the rectangles x,y,width,height fields.
- Parameters:
g
c
p
r
update
public void update(Graphics g)
-
Shouldn't be called.
- Overrides:
update
in class Container
- Parameters:
g
