Hi all,

I'm trying to add an icon list to a GTK Window using setIconList(), but what the function expects is a ListG of Pixbufs.

The way I understand it, I have to instantiate the Pixbufs, build a ListG of void pointers to the Pixbufs, and pass that to setIconList().

Here is how I assume this process would play out:

```

Pixbuf airportImage1, airportImage2, airportImage3, airportImage4;
void * image1, image2, image3, image4;

airportImage1 = new Pixbuf("images/airport_25.png");
airportImage2 = new Pixbuf("images/airport_35.png");
airportImage3 = new Pixbuf("images/airport_60.png");
airportImage4 = new Pixbuf("images/airport_100.png");
image1 = &airportImage1;
image2 = &airportImage2;
image3 = &airportImage3;
image4 = &airportImage4;

ListG listG = null;
	
listG = listG.append(image1);
listG = listG.append(image2);
listG = listG.append(image3);
listG = listG.append(image4);

setIconList(listG);

```

But this, although it compiles, just dies when it hits all those append() statements.

Would someone please tell me where I'm going off track?

I get the segfault to go away with

  ListG list = new ListG(null);

which is usage you can find in APILookupGLib.txt

Ah! Thanks, mipri. I didn't think to read through the unit tests.
