Constructor Detail

ImageBox

public ImageBox(java.net.URL img_url,
                java.net.URL link_url)

Constructs an ImageBox.

Parameters:

img_url - the URL of the image. The image isn't downloaded until doLayout(Graphics, JComponent, int) is called.

link_url - the URL which this image links too. If the image doesn't link to anywhere, link_url should be null.

Method Detail

doLayout

public void doLayout(java.awt.Graphics g,
                     javax.swing.JComponent c,
                     int w)

Calculates the width and height of the image. The image is downloaded and then meassured.

Overrides:

doLayout in class AbstractBox

Following copied from interface: Box

Parameters:

g - the graphics context. Some boxes, like TextFragments, need a graphics context before they can determine their width and height.

c - the component into which the box will be drawn. An ImageBox needs to know the component to calculate the width and height.

w - the width available for to the Box.

drawAt

public void drawAt(int x,
                   int y,
                   DocumentView v)

Description copied from interface: Box

Draws the box with it's upper-left corner at (x, y).

Overrides:

drawAt in class AbstractBox

Following copied from interface: Box

Parameters:

v - the DocumentView that does the actual drawing.

x - the x-coordinate of the upper-left corner.

x - the y-coordinate of the upper-left corner.
