TreeStore提供分等級，分層次的數據存儲，而ListStore提供表格的數據存儲,TreeModelSort提供一個排序的模型，TreeModelFilter提供數據子集。通常有以下幾個步驟：

1.創建一個tree model對象，通過ListStore或TreeStore

2.TreeView widget 創建并與tree model關聯

3.一個或多個TreeViewColumns被創建并插入到TreeView，每個代表一列

4.對于每個TreeViewColumn，CellRenderers被創建并加入TreeViewColumn

5.設置每個CellRenderer的屬性

6.TreeView被插入并顯示在Window或ScrolledWindow中

7.響應用戶的操作
