Hello Herve
I don't really get it why you need to avoid setting the clip,
but anyway the following may be interesting to you

Piet is transforming Swing components using JXLayer component

Hello,
I'm new to this mailing list and I'm not *really* asking how to do it
because I know how it's possible to do it by using a hack (mainly
getting and setting the BUFFER and TILE parts of the "flags" field for
the JComponent by reflection, and "rewriting" the paintChildren method
without the clipping part). I'm using it in the
http://sourceforge.net/projects/j661/ project to be able to use
custom Swing containers which only offset the position or transform
their children graphic context, without clipping them (allowing to use
negative positions for the children widgets, for example).
I'm asking if there is a way to do this without playing with the
private "flags" field, because I need to be able to do the same thing
in a restricted JNLP environment. I know a "regular"' way to do this,
but it would be a little cumbersome (offsetting the positions of all
children widgets in the parent container, to be sure that the
positions of the children are never negative, for example). But it's
not very good for performance when something change in the parent
container....
There are many projects which either play with this private field, or
use transforms, but in this later case they still apply a clipping. Is
it possible to play with the Graphics2D clippings for example before
using the JComponent paintChildren method - or would this approach
work ? Or would the only way to do it without compromising Security
be to have a way to get / set the TILE and BUFFER value of the "flags"
field without reflection ?
Thanks by advance if you have ideas about this, and sorry if this
prose is not crystal clear ;)
Regards,
Herve
