Using python I would like to determine the eraser radius, calculate a new radius and update the widget.
I can modify the radius value, but unable to update the parameter on the widget.
Using this from VolumeEraser.gui import Volume_Eraser_Dialog v=Volume_Eraser_Dialog() r=v.sphere_radius_scale.value() print r r=r*0.5 v.sphere_radius_scale.set_value(r)
If I have a widget radius of 8000,it accesses a default value of 2 rather than the value in the dialog box, and changes the sphere radius to 1. printing v I get the impression that I am access a different widget/gui.

Hi Matt,
If you call Volume_Eraser_Dialog() then you get a new dialog. Here's the way to do it.
from VolumeEraser import gui d = gui.volume_eraser_dialog(create = True) r = d.sphere_radius()
25.3500015259
s = d.sphere_radius_scale.value()
25.3500015259
rnew = 100 d.sphere_radius_scale.set_value((rnew/r)*s) r = d.sphere_radius()
100.0

not clear on the concept of radius and radius scale. Why both?
now the next thing I want to try is to move the xyz coordinates. I plan to move away from the mouse to get better control.

Not sure why the volume eraser code calls the radius slider "radius scale". I see that it adjust the range of the scale to be 0 up to the size of the current volume data box. I guess it was called "radius scale" for historical reasons and that the value was not the actual radius in some previous version of the code, but was a scale factor of the current sphere radius.
