Updating display in a CompositeImage Virtual Hyperstack

[Bill Mohler]

Hi All-

I'm driving myself nuts with this one:

I can create a Virtual Hyperstack which displays the multiple channels
as CompositeImage.

The sliders, mousewheel, arrow keys all work perfectly when I adjust
position in the hyperstack.

Now I'm using a PluginFrame with some adjusters to change properties of
the display.  If I have the hyperstack animating, these adjustments are
seen in the image in "real-time".  If the hyperstack is in a single czt
position, however, no adjustments are seen in the image until I move to
a new position in z or t.

In other words, the adjustments do not update the display unless the
hyperstack position is updated.  This is different from the behavior of
the ContrastAdjuster, which gives a live update even when the image is
not animating.

What is a method that can be called at the end of an adjustment in my
PluginFrame that will make the display do a live-update?  I have tried
inserting a long list of commands (one at a time) that seem like they
might be bringing about the effect in either the ConstrastAdjuster or in
the StackWindow.adjustmentValueChanged() method.  But none gives the
desired result.  I'm fairly confident that I'm missing something simple,
but I don't know what.

Thanks for any advice,
Bill

Hi William,

is it the ImagePlus.updateAndDraw() that is missing?
If your image is not in an ImagePlus but in a PlugInFrame you  
probably have to duplicate the code of ImagePlus.updateAndDraw() for  
your own updateAndDraw() method.

No, the image is in an ImagePlus/CompositeImage.
I think ImagePlus.updateAndDraw() is the first thing that I tried and failed with...
I just tried again, and it doesn't work.

Thanks,
Bill
