Those classes are registered with the gobject type system. G_DEFINE_TYPE expands into code defining things like ir_wave_display_get_type(), which does the registration on first call. I think you need at least to change the type names in the registration like this: G_DEFINE_TYPE(IRWaveDisplayAmb, ir_wavedisplay, GTK_TYPE_DRAWING_AREA); and replace all IRWaveDisplay with IRWaveDisplayAmp (not tested...). ciao Andreas _______________________________________________ Linux-audio-dev mailing list Linux-audio-dev@lists.linuxaudio.org http://lists.linuxaudio.org/listinfo/linux-audio-dev
