All Implemented Interfaces:: Validationable

Direct Known Subclasses:: LwTitledBorder

public class LwBorder
extends LwView

The class implements set of borders views. The library registers the views as static objects that can be used by the border view key. It is possible to use the following keys to get a border view as a static object:

"br.etched"
"br.raised"
"br.raised2"
"br.sunken"
"br.sunken2"
"br.plain"
"br.dot"

It is possible to specify a colors set that should be used to render the border. The colors set is represented with the three colors: the brightest color, middle color and the darkest color. Use on of the following ways to set the colors:

By the border view class constructor.
By default. In this case the "white", "gray" and "gray" colors will be used.
By the "lw.properties" file. For this purpose add the colors into the properties file with the following keys: "br.c1", "br.c2", "br.c3".

The sample below illustrates how the borders set can be used for light weight components:

    ...
    LwLabel label = new LwLabel("Label Text");
    label.getViewMan(true).setBorder("br.dot");
    ...
