Hi all
I'm developing an interactive plugin and I have some problems upgrading
imageStack.
To understand working mode I try a simple code: (   I prefer if code not
use IJ.run("Add slice")    )
-----------------------------------------------------------------
int width = 200;
int height = 200;
ImageStack stack = null;
ImagePlus imp = null;

stack = new ImageStack(width, height);
ColorProcessor cp1 = new ColorProcessor(width,height);
stack.addSlice("", cp1, 0);
imp = new ImagePlus("", stack);

imp.show();

ColorProcessor cp2 = new ColorProcessor(width,height);
cp2.setColor(Color.RED);
cp2.fill();

//stack.addSlice("", cp2, 1);
imp.getImageStack().addSlice("", cp2,1);
imp.updateAndRepaintWindow();
-----------------------------------------------------------------

Code works ONLY if I call "imp.show();"  at the end but this is a
problem because I would show first slice and UPDATE stack when other
slide will be added.
PS: I prefer if code not use IJ.run("Add slice")

Thanks a lot
