Constructor Detail

QPanel

public QPanel()

Constructor, calls the super constructor.

QPanel

public QPanel(boolean isDoubleBuffered)

Constructor, calls the super constructor.

Parameters:

isDoubleBuffered - is double buffered.

Method Detail

updateUI

public void updateUI()

Sets the look and feel to the Bounce Panel UI look and feel. Override this method if you want to install a different UI.

Overrides:

updateUI in class JPanel

setGradientBackground

public void setGradientBackground(boolean enable)

Enables the filling of the background gradually to achieve a 'subtle' 3D effect. It starts in the top left hand corner with the background color and ends in the bottom right hand corner with the gradient color or if this color is null with a darker version of the background color.

Parameters:

enable - the gradient filling of the background when true.

isGradientBackground

public boolean isGradientBackground()

Returns whether the 'subtle' 3D gradient effect is enabled.

Returns:

true when the gradient filling of the background is enabled.

getGradientColor

public Color getGradientColor()

Returns the color used for the lower right corner of the gradient 3D effect. When the color is null, a darker version of the background color is used instead.

Returns:

the color for the lower right corner.

setGradientColor

public void setGradientColor(Color color)

Sets the color used for the lower right corner of the gradient 3D effect. When the color is null, a darker version of the background color is used instead.

Parameters:

color - the color for the lower right corner.

setBackgroundImage

public void setBackgroundImage(ImageIcon image)

Sets the background image for this panel.

Parameters:

image - the background image.

getBackgroundImage

public ImageIcon getBackgroundImage()

Returns this panel's background image.

Returns:

the background image.

setBackgroundImageMode

public void setBackgroundImageMode(int mode)

Sets the way the background image is displayed, it can be any of the following modes: CENTERED, The middle of the image is anchored in the middle of the panel, when the image is bigger than the panel, the image will be clipped. TOP_LEFT, The top left of the image is anchored in the top left part of the panel, when the image is bigger than the panel, the image will be clipped. TOP_RIGHT, The top right of the image is anchored in the top right part of the panel, when the image is bigger than the panel, the image will be clipped. BOTTOM_RIGHT, The bottom right of the image is anchored in the bottom right part of the panel, when the image is bigger than the panel, the image will be clipped. BOTTOM_LEFT, The bottom left of the image is anchored in the bottom left part of the panel, when the image is bigger than the panel, the image will be clipped. STRETCHED, The image is resized to fit the panel. TILED, The image is drawn repeatedly until the whole panel is filled (like tiles), starting at the top left corner, images on the right and bottom edges of the panel are likely to be clipped.

Parameters:

mode - the background image display mode.

getBackgroundImageMode

public int getBackgroundImageMode()

Returns the mode in which the background image is displayed.

Returns:

the background image mode.
