Problem
How do you get absolute pathnames using a URL to work in SerializableImage instead of relative pathnames?
Cause
The standard way to specify images in SerializableImage is relative pathnames. Some programmers might want to specify an absolute pathname to a particular file in the local machine (which does limit portability). The JWidgets example code for the ImageButtonDemo contains the line:
new SerializableImage(getClass().getResource(../../images/sixstates.gif);
The image in question is on /home2/users/nice/sixstatessmall.gif. The localhost refers to the local machine, instead of an external machine such as www.roguewave.com.
Action
Substitute the following:
URL url=null;
try {
url = new URL(file://localhost/home2/users/nice/sixstatessmall.gif);
}
catch (MalformedURLException e) {
e.printStackTrace();
}
SerializableImage image = new SerializableImage(url);
