This method is a simpler variation of gtk_builder_connect_signals_full(). It uses's introspective features (by opening the module %NULL) to look at the application's symbol table. From here it tries to match the signal handler names given in the interface description with symbols in the application and connects the signals. Note that this function can only be called once, subsequent calls will do nothing. Note that this function will not work correctly if is not supported on the platform. When compiling applications for Windows, you must declare signal callbacks with , or they will not be put in the symbol table. On Linux and Unices, this is not necessary; applications should instead be compiled with the -Wl,--export-dynamic CFLAGS, and linked against gmodule-export-2.0.
