> A question about running commands which depend on the current window. Java

>
> I have a Java plugin which generates several ImagePlus objects, and shows
> them.
>
> The last one is an 8-bit image to which I want to apply a LUT.
>
> I (naîvely?) assumed that the last ImagePlus.show() call would make that
> window the current one, so I tried:

>
> ...
> ip1.show();
> ip2.show();
> ip3.show();
> IJ.run("royal");
>
> ip1 is an RGB image.
> ip2 is a 32-bit float image.
> ip3 is an 8-bit byte image.
>
> My expectation was that the LUT would be applied to the 3rd image (the 8-bit
> byte image). Instead, it was applied to the 2nd image (the 32-bit float
> image).
>
> I suspected some sort of race condition, so I tried this:
> ...
> ip1.show();
> ip2.show();
> ip3.show();
> WindowManager.setWindow(ip3.getWindow());
> IJ.run("royal");
>
> No joy! The LUT is *still* applied to ip2, the 32-bit float image.
