You can use the gtk_object_getv() function.  Here is a small example
from the Gnomecal sources:

	GtkArg args[3];
	double text_height;
	double clip_height;
	double y_offset;

	args[0].name = "text_height";
	args[1].name = "clip_height";
	args[2].name = "y_offset";
	gtk_object_getv (GTK_OBJECT (mv->text[day_index]), 3, args);

	text_height = GTK_VALUE_DOUBLE (args[0]);
	clip_height = GTK_VALUE_DOUBLE (args[1]);
	y_offset = GTK_VALUE_DOUBLE (args[2]);

In this case, mv->text[day_index] is a GnomeCanvasText item.
