如何在ttk Python33中将值更新到组合框下的列表框 [英] How to update values to the listbox under Combobox in ttk Python33

问题描述

创建组合框时，列表中没有任何项目。现在，当我单击下拉按钮时，将调用一个函数（通过postcommand选项），但是一旦在函数中，我便不知道如何在组合框的列表框中设置值。

When I create the Combobox, it has no items in the list. Now when I click on the dropdown button a function is called (via the postcommand option), but once in my function I don't know how to set the values in the listbox of the Combobox.

编写类似这样的代码：

    #update list upon drop down
    self.cbox = Combobox(self, width = 10, postcommand = self.updtcblist)

    def updtcblist(self):
        list = self.getPortLst()
        self.cbox.getlistbox.set(list) #getlistbox doesn't work

谢谢

推荐答案

回答了我自己的问题。

我终于找到了一个有用的示例，并使其与以下代码一起使用：

I Finally found an example that helped, and got it to work with the following code:

#update list upon drop down
self.cbox = Combobox(self, width = 10, postcommand = self.updtcblist)

def updtcblist(self):
    list = self.getPortLst()
    self.cbox['values'] = list

此功能可根据需要工作。

This works as desired.
