Python Gtk.CellRendererText() color

Question

此TreeView具有5列，其中包含USB设备详细信息列表，它显示设备名称，模型，序列号和状态，所有这些都显示在列表上，我试图实现的目标是颜色代码"状态"仅列，如果读取"状态"，则将颜色编码为红色，否则将其编码为绿色。下面的代码当前是颜色代码整列作为红色，它只是忽略了任何只读设备。我花了几个小时在网上找到答案，但找不到任何答案。谁能帮我吗？

def build_device_list(self):
    self.dev_store_len = len(self.device_list_store)
    for i, column_title in enumerate(["Device", "Model", "Serial Number","Size"]):
        self.renderer = gtk.CellRendererText()
        column = gtk.TreeViewColumn(column_title, self.renderer, text=i)
        self.device_list_treeview.append_column(column)
        column.set_sort_column_id(i)
    self.renderer_status = gtk.CellRendererText()
    column_status = gtk.TreeViewColumn("Status",self.renderer_status, text=4)
    for x in range(0, self.dev_store_len):
        if self.device_list_store[x][4] == "READ-WRITE":
           self.renderer_status.set_property("foreground", "Red")
           self.device_list_treeview.append_column(column_status)
        else:
           self.renderer_status.set_property("foreground", "Green")
           self.device_list_treeview.append_column(column_status)
    self.scrollable_treelist = gtk.ScrolledWindow()
    self.scrollable_treelist.set_vexpand(True)
    self.outter_box.pack_start(self.scrollable_treelist,False,True,0)
    self.scrollable_treelist.add(self.device_list_treeview)

对于任何看这个问题的人来说，这是工作代码：

def build_device_list(self):
    self.dev_store_len = len(self.device_list_store)
    for i, column_title in enumerate(["Device", "Model", "Serial Number","Size"]):
        self.renderer = gtk.CellRendererText()
        column = gtk.TreeViewColumn(column_title, self.renderer, text=i)
        self.device_list_treeview.append_column(column)
        column.set_sort_column_id(i)
    self.renderer_status = gtk.CellRendererText()
    column_status = gtk.TreeViewColumn("Status",self.renderer_status, text=4, foreground=5)
    self.device_list_treeview.append_column(column_status)
    for x in range(0, self.dev_store_len):
        if self.device_list_store[x][4] == "READ-WRITE":
           self.device_list_store[x][5] = "Red"                
        else:
           self.device_list_store[x][5] = "Green" 
    self.scrollable_treelist = gtk.ScrolledWindow()
    self.scrollable_treelist.set_vexpand(True)
    self.outter_box.pack_start(self.scrollable_treelist,False,True,0)
    self.scrollable_treelist.add(self.device_list_treeview)

基本上，您需要一个隐藏的ListStore列，该列以您的颜色保存字符串值。然后，TreeView列需要将前景属性设置为那个隐藏的列。
