[sane-devel] Re-reading options with Xsane

[Dave Close]

It is possible to define a backend option as SANE_CAP_SOFT_DETECT only.
Such options are essentially read-only information sources for a frontend.
Xsane reads the value of such an option and displays it in a grayed-out
form. That seems natural and correct to me.

But the value of such an option may change over time. Is there any way to
cause Xsane to re-read the option and display the new value? Preferably, 
without having to initiate a scan or other physical action?
