But the program gives some warning messages:

GLib-GObject-WARNING **: unable to set property pixbuf' of type GdkPixbuf' from value of type `gchararray'

Also I shouldn't figured out what kind of data type to ListStore's constructor. So I simly passed a GType.STRING.

Set the first column type as a pixbuf column:

auto dataModel = new ListStore([Pixbuf.getType(), GType.STRING, 
GType.STRING]);
