correct. the c code works. to be honest - i work on the c. with the c. apps too. i never look at the python so i have no idea what it is doing. but you did the 100% right thing. check the c code and see what it's doing api/behavior-wise. this is how it "should be". to be totally honest... it's just as easy to use elm from as from python, so poking around the c api is possible and easy. > On Mon, Aug 24, 2009 at 10:52 AM, Laszlo > KREKACS<laszlo.krekacs.l...@gmail.com> wrote: > > Unfortunately my C knowledge are almost nonexistant, so > > maybe it will take some weeks to get there, writing a simple > > demonstration application in C. > > As others pointed out, the preferred way of doing C development is > installing elementary on > the desktop machine and develop on it (and crosscompile for the neo). > > So I installed elementary, and ran the test application from here: > http://trac.enlightenment.org/e/wiki/Elementary > > Now, I modified the source, to get the evas canvas (evass), and print > some info about > it, and add other evas object to it, so not some elementary widget, > but pure evas object. > > In C, everything works as expected, evas_object_evas_get does return > with a valid > evas canvas object.
