[chimera-dev] S3D extension

[Tom Goddard]

Hi Matt,

	from chimera import tkgui
	tkgui.setScreenMMWidth(w)
	w = tkgui.getScreenMMWidth()

Here MM stands for millimeters.

In general you don't want your Python code to find graphical user interface controls (entry fields, sliders, …) and modify their values.  Instead you modify the parameter values and the graphical user interface should detect the change and update themselves.  The case of the Icosahedron tool is just a hack where only the graphical user has access to the radius parameter.

	Tom
