Re: R: Best way to create interactive GUI apps with octave?

[schnumbl]

Hi Michael, 

I refer to the example from Martin Helm (see above, Apr 22, 2010; 07:37pm,
http://octave.1599824.n4.nabble.com/Best-way-to-create-interactive-GUI-apps-with-octave-td2019418.html).

Are you able to run his callback example (test_java.m, callback.m,
OctSlider.java, ExtensionFileFilter.java) ?

(I deleted the line "vtk_surf(rand(10));" in test_java.m because my octave
does not know the command.)

Maybe the problem is that the "OctSlider.java" needs something like 

static {
System.loadLibrary("LibraryWithTheCallFunction");
} 

??
