File
Specifies the file name and path of the image component. When the GUI Builder
builds the panel, the image is found by using the file name and searching
relative to where the GUI Builder started. For example, if the GUI Builder
started from c:\mydirpanel and you specify ../img/myimage.gif
as the file parameter for the component, the image is only loaded from
the c:\mydirpanel\img subdirectory. You can also click
to locate the file.
When you preview a panel that contains a component referenced by File,
the component is found by using the CLASSPATH environment variable. This
is also true when you display the panel by using the runtime framework.
