4 | * This demo displays a grid of colors. |
5 | * |
6 | * It is using a GtkGridView, and shows how to display |
7 | * and sort the data in various ways. The controls for |
8 | * this are implemented using GtkDropDown. |
9 | * |
10 | * The dataset used here has up to 16 777 216 items. |
11 | * |
12 | * Note that this demo also functions as a performance |
13 | * test for some of the list model machinery, and the |
14 | * biggest sizes here can lock up the application for |
15 | * extended times when used with sorting. |
