Source File of Circle

I want to know the Logic of making circle in LibreCAD. I had download and install its source from github. Where is source file of circles( various ways) locate?

you can find most methods in class,

RS_Circle
RS_Creation

Actually instances of circle creation should be in RS_ActionDrawCircle* classes (in folder librecad/src/actions/ )

Please keep adding your new knowledge of LibreCAD to our wiki.

Got it. Thanks.
Ok. I Will share my work and Knowledge.

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

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;
        }

One more thing, please be aware of that both 2.0 and 1.0 won't accept new feature any more.

You can help bug fixing in 2.0 and 1.0, while prepare to contribute new features to coming 2.1 (still not branched yet).

something of high priority for 2.1: to support both bezier and spline, implementation of hyperbola/parabola
