Hi zac,

The GUI widgets are kept in librecad/src/ui/forms/

for example: qg_circleoptions.ui

Those widgets are shown/hidden by rs_actions ( in folder, librecad/src/actions/ ), for example:

rs_actiondrawcirclecr

the class, RS_ActionDrawCircleCR has virtual functions: hideOptions() showOptions()

the widgets simply set radius by calling:  

ActionDrawCircleCR::setRadius(double r) {
                data.radius = r;
        }

I want the file where radius of circle is taken from  GUI andvalue is stored in a variable.
Please help.
