GTK+ is basen on GObject, which stores most of parameters with GValue. If you will look how GObject's objects works, you will see, that if they are well implemented, they will release used memory every time, when we will try change value of some parameter, which is allocating memory (like strings in GtkLabel). Moreover I must say, that you aren't completely right saying, that GTK+ based programs leaks memory, or that their memory usage is high. If you are working with some GTK+ application, you can see, that whole program allocates pretty much memory, that is right. However it doesn't mean, that this program uses whole allocated memory whole the time, because it doesn't, it use only some part of it and rest is treated as buffer for future memory usage. Such behave makes GLib based programs (GTK+ is based on GLib, but GLib provides memory management subsystem, so GLib is responsible for memory usage) faster, because they doesn't need time for physical allocating and releasing memory. Programs are faster (at least theoretically), but they allocate more memory then non GLib programs, so for some of us it will be waste of memory and for rest not. Note, that Pango uses GLib too. -- Pozdrawiam!
