Constructor Detail

GObImage

protected GObImage()

Create an empty image GraphicalObject.

GObImage

public GObImage(Image img)

Create a GraphicalObject around the image specified.

Parameters:

img - is a reference to the Image object to display.

GObImage

public GObImage(String strFileName)

Create a GraphicalObject of the image given the specified filename.

Parameters:

strFileName - is the name of the image file to load. It can load up whatever files Java can, so as of JDK1.3 this includes GIF, JPG, and PNG.

GObImage

public GObImage(URL url)

Create a GraphicalObject of the image given the specified url.

Parameters:

url - is the URL object to load up. It can load up whatever files Java can, so as of JDK1.3 this includes GIF, JPG, and PNG.

Method Detail

imageUpdate

public boolean imageUpdate(Image img,
                           int infoFlags,
