Method Summary

protected Dimension	calculatePreferredSize() Overriden to calculate non-realised preferred size.
int	getHeight() Returns the height of the peer
Dimension	getSize() Return how large this panel would like to be if it's inside a ScrollPane, rather than how large it actually is.
int	getWidth() Returns the width of the peer
void	setBorder(Border b) Sets the border for the Panel
void	setSwingWTParent(Container parent) Callback for when this is added to a Container to create the peer and load cached values.

Constructor Detail

JPanel

public JPanel()

Creates a new JPanel

JPanel

public JPanel(boolean isDoubleBuffered)

Creates a new JPanel with the specified buffering scheme

Parameters:

isDoubleBuffered - Whether or not to double buffer paint callbacks

JPanel

public JPanel(LayoutManager layout)

Creates a new JPanel with the specified layout

Parameters:

layout - The layout manager to use

JPanel

public JPanel(LayoutManager layout,
              boolean isDoubleBuffered)

Creates a new JPanel with the specified layout and buffering scheme

Parameters:

layout - The layout manager to use

isDoubleBuffered - Whether or not to double buffer paint callbacks

JPanel

public JPanel(LayoutManager2 layout)

Creates a new JPanel with the specified layout

Parameters:

layout - The layout manager to use

JPanel

public JPanel(LayoutManager2 layout,
              boolean isDoubleBuffered)

Creates a new JPanel with the specified layout and buffering scheme

Parameters:

layout - The layout manager to use

isDoubleBuffered - Whether or not to double buffer paint callbacks

Method Detail

calculatePreferredSize

protected Dimension calculatePreferredSize()

Overriden to calculate non-realised preferred size.

Overrides:

calculatePreferredSize in class Component

setSwingWTParent

public void setSwingWTParent(Container parent)
                      throws java.lang.Exception

Callback for when this is added to a Container to create the peer and load cached values.

Overrides:

setSwingWTParent in class JComponent

Throws:

java.lang.Exception

setBorder

public void setBorder(Border b)

Sets the border for the Panel

Overrides:

setBorder in class JComponent

Parameters:

b - The new border

getSize

public Dimension getSize()

Return how large this panel would like to be if it's inside a ScrollPane, rather than how large it actually is. This is used by layout managers when determining how to layout the components. If you need the actual size of a JPanel in a scroll pane, use getPeerSize() which always return the correct values.

Overrides:

getSize in class Component

getWidth

public int getWidth()

Returns the width of the peer

Overrides:

getWidth in class Component

Returns:

the width

getHeight

public int getHeight()

Returns the height of the peer

Overrides:

getHeight in class Component

Returns:

the height
