// Create a ListStore ListStore store = new ListStore(typeof(int), typeof(string), typeof(double)); // Set the sort function for the items in the ListStore store.SetSortFunc(0, (TreeIter a, TreeIter b) => { int aValue = (int)store.GetValue(a, 0); int bValue = (int)store.GetValue(b, 0); return aValue.CompareTo(bValue); });
// Create a ListStore ListStore store = new ListStore(typeof(string), typeof(int), typeof(double)); // Set the sort function for the items in the ListStore store.SetSortFunc(1, (TreeIter a, TreeIter b) => { int aValue = (int)store.GetValue(a, 1); int bValue = (int)store.GetValue(b, 1); return aValue.CompareTo(bValue); }); // Add some items to the ListStore store.AppendValues("Item 1", 50, 5.99); store.AppendValues("Item 2", 25, 9.99); store.AppendValues("Item 3", 75, 2.99); // Display the sorted items in a TreeView TreeView view = new TreeView(store); view.AppendColumn("Name", new CellRendererText(), "text", 0); view.AppendColumn("Quantity", new CellRendererText(), "text", 1); view.AppendColumn("Price", new CellRendererText(), "text", 2);In this example, we create a ListStore with three columns - a string, an integer, and a double. We then use the SetSortFunc() function to set a custom sorting function for the second column in the ListStore. This function sorts the items in the ListStore based on the integer value in the second column. We then add some items to the ListStore and display them in a TreeView with the sorted items based on the quantity column. Package/Library: Gtk# (GtkSharp)
