one more level editor in gtk glade

Hi i m new here
i’m french so i try to speak english

i’m writing a level editor for fun because i couldn’t do what i wanted with the other.
it’s a beta but it could add object,move them,move the camera,save and load.

download code :

it’s working on linux and should work on windows with some debug on filename /

what do you think on it?

does someone know how to put base.win image in a gtk drawingarea ?
