kiwi.ui.KPanel
An extension of JPanel
that provides some additional
functionality including support for background texture tiling and
named-component lookup. Lightweight components nested within the
KPanel
should be transparent and unbuffered; the tiled
background will not show through heavyweight components.
Note that images with transparent portions should not be used with
KPanel
s.
A KPanel
will always be transparent if a background
texture has not been specified. Therefore KPanel
s may be
safely nested if only the outermost instance has a texture applied. It is
recommended that KPanel
s always be used in place of Swing
JPanel
s.
In most cases it is convenient to use a KFrame
to provide a
textured background for an entire window.
If a solid color background is desired in place of a texture, then the
outermost KPanel
should be made opaque via the call
setOpaque(true)
, and the texture should be turned off via a
call to setTexture(null)
. The background color can be set
using setBackground()
as usual.
