Yes, drag&drop may be not very easy. And zooming and panning/scrolling for a plain (cairo) drawing area may be not really trivial, when you need to grab objects with the mouse. I did try it two years ago from Ruby -- not really difficult, but it takes some time to get the math right. Have not found time to clean it up yet. ( http://www.ssalewski.de/PetEd.html.en) Of course, if you do C++ and have not much experience in GTK already you may try https://qt-project.org/doc/qt-4.8/graphicsview.html I have never find time and motivation to test that. _______________________________________________ gtk-app-devel-list mailing list gtk-app-devel-list@gnome.org https://mail.gnome.org/mailman/listinfo/gtk-app-devel-list
