[chimera-dev] changing the radius value on volumeEraser

[Dougherty, Matthew T]

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.

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

        Tom
