Using OpenCV in GTK applications Although OpenCV comes with its own windowing system for displaying any OpenCV images, for fully functional applications with user interface elements such as buttons, menus, and radio buttons, maybe you would find it useful to use widget libraries such as GTK+ or QT. Drawing OpenCV image surfaces in GTK+ applications is not much of a difficult task than adding a couple of extra lines in your existing GTK+ applications. And again there are plenty of ways to accomplish the same results, but here I will show how I have achieved it. The sample program here is written using GTK+ C++ binding GTKmm, but the technique and functions should be same across all the GTK+ bindings. As usual we create a GTK+ top level window by creating a MainWindow object. MainWindow, which is itself a GtkWindow widget contains one GtkFrame and one GtkDrawingArea widgets. The class definition of MainWindow is shown below: class MainWindow : public Gtk::Window {     pro...
