Yes, first do seticonsize(w, h);
Then the icon variable is actually a TDrawingPanel object that you can use various functions such as:

• icon.drawimage(int x, int y, str imagefilename)
• icon.drawimagerectangle(int x, int y, str imagefilename, int sourcex, int sourcey, int sourcewidth, int sourceheight)
• icon.drawimagestretched(int x, int y, int width, int height, str imagefilename, int sourcex, int sourcey, int sourcewidth, int sourceheight)

Here's an example:

NPC Code:

---

new GuiTreeViewCtrl("mytree") {

  resize(0, 0, 50, 100); // sets x, y, w and h

  seticonsize(32, 32);

  clearnodes();

  with (addnode("Category A")) {

    icon.drawimagestretched(0, 0, 32, 32, "block.png", 0, 0, 32, 32);

    with (addnode("Item A")) {

      icon.drawimagestretched(0, 0, 32, 32, "head0.png", 0, 0, 32, 64);

    }

    with (addnode("Item B")) {

      icon.drawimagestretched(0, 0, 16, 16, "bcalarmclock.png", 0, 0, 32, 32);

      icon.drawimagestretched(16, 0, 16, 16, "bcalarmclock.png", 0, 0, 32, 32);

      icon.drawimagestretched(16, 16, 16, 16, "bcalarmclock.png", 0, 0, 32, 32);

      icon.drawimagestretched(0, 16, 16, 16, "bcalarmclock.png", 0, 0, 32, 32);

    }

  }

}
