public class ImageFigure
extends Figure

A Figure that simply contains an Image. Use this Figure, instead of a Label, when displaying Images without any accompanying text. This figure is not intended to have a layout mananger or children.

Note that it is the client's responsibility to dispose the given image. There is no "free" resource management in draw2d.

Constructor Detail

ImageFigure

public ImageFigure()
Constructor
The default alignment is PositionConstants.CENTER.


ImageFigure

public ImageFigure(Image image)
Constructor
The default alignment is PositionConstants.CENTER.

Parameters:
image - The Image to be displayed

ImageFigure

public ImageFigure(Image image,
                   int alignment)
Constructor

Parameters:
image - The Image to be displayed
alignment - A PositionConstant indicating the alignment
See Also:
setImage(Image), setAlignment(int)
Method Detail

getImage

public Image getImage()
Returns:
The Image that this Figure displays

getPreferredSize

public 
Dimension getPreferredSize(int wHint,
                                  int hHint)
Calculates the necessary size to display the Image within the figure's client area.

Specified by:
getPreferredSize in interface IFigure
Overrides:
getPreferredSize in class Figure
See Also:
Figure.getPreferredSize(int, int)

paintFigure

protected void paintFigure(
Graphics graphics)
Description copied from class: Figure
Paints this Figure's primary representation, or background. Changes made to the graphics to the graphics current state will not affect the subsequent calls to Figure.paintClientArea(Graphics) and Figure.paintBorder(Graphics). Furthermore, it is safe to call graphics.restoreState() within this method, and doing so will restore the graphics to its original state upon entry.

Overrides:
paintFigure in class Figure
Parameters:
graphics - The Graphics used to paint
See Also:
Figure.paintFigure(Graphics)

setAlignment

public void setAlignment(int flag)
Sets the alignment of the Image within this Figure. The alignment comes into play when the ImageFigure is larger than the Image. The alignment could be any valid combination of the following:
  • PositionConstants.NORTH
  • PositionConstants.SOUTH
  • PositionConstants.EAST
  • PositionConstants.WEST
  • PositionConstants.CENTER or PositionConstants.NONE

Parameters:
flag - A constant indicating the alignment

setImage

public void setImage(Image image)
Sets the Image that this ImageFigure displays.

IMPORTANT: Note that it is the client's responsibility to dispose the given image.

Parameters:
image - The Image to be displayed. It can be null.
