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 following keys to get a border view as a static object:

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

Field Summary

static int	DOT The DOT border type.
static int	ETCHED The ETCHED border type.
static int	PLAIN The PLAIN border type.
static int	RAISED The RAISED border type.
static int	SUNKEN The SUNKEN border type.
static int	SUNKEN2 The SUNKEN2 border type.

Paints the view using a given width and height. The location where the view has to be painted is determined with x and y coordinates. This method is implemented with the border view and this defines face of the view.

Overrides:

paint in class LwView

Parameters:

g - the specified context to be used for painting.

y - the y coordinate.

w - the width of the view.

h - the height of the view.

d - the owner component.

getInsets

public java.awt.Insets getInsets()

Gets the view insets. The insets is used to calculate the owner component insets.

Overrides:

getInsets in class LwView

Returns:

an insets of the view.

calcPreferredSize

protected java.awt.Dimension calcPreferredSize()

Description copied from class: LwView

Calculates and returns the view preferred size. The method has not to use the view insets to compute the preferred size.

Overrides:

calcPreferredSize in class LwView

Following copied from class: org.zaval.lw.LwView

Returns:

a "pure" preferred size of the view.
