Tkinter 网格未将小部件放置在正确的列中

Question

我正在尝试使用 tkinter 网格创建一个 ui，以允许用户在两个不同的框架上输入某些值，我希望能够在这两个框架之间进行切换。

我已将不同列中的所有小部件网格化，但是它们都出现在同一列中。

这是我的代码：

class GeneralFrame(ttk.Frame):
    def __init__(self, *args):
        super().__init__(*args, padding=10, width=1200, height=600)
        self.grid_propagate(1)

class EntryBox(GeneralFrame):
    def __init__(self, x_location, y_location, *args):
        super().__init__(*args)
        self.entry_box = ttk.Entry(self)
        self.entry_box.place(x=x_location, y=y_location)
        print("Placed")

    def get_data(self):
        return(self.entry_box.get())

class GliderFrame(GeneralFrame):
    def __init__(self, *args):
        super().__init__(*args)

        self.main_frame = MainFrame()
        self.main_frame.grid(column=0, row=0)

App().mainloop()

这是输出：

Answer 1

Tkinter 网格未将小部件放置在正确的列中。

我正在尝试使用 tkinter 网格创建一个 ui，以允许用户 在我希望能够的两个不同框架上输入某些值 之间切换

问题可以解决，通过在

MapFrame()

类的 Label 小部件中添加 self 。

还可以通过在第 179 行添加 self.main_frame.grid(column=1,..) 而不是 self.main_frame.grid(column=0,..) 来查看显示的按钮。

MapFrame()

课程片段：

self.turnpoint1_label = ttk.Label(self,text=str("Turpoint 1:"))
self.turnpoint2_label = ttk.Label(self,text=str("Turpoint 2:"))
self.turnpoint3_label = ttk.Label(self,text=str("Turpoint 3:"))
self.turnpoint4_label = ttk.Label(self,text=str("Turpoint 4:"))
self.turnpoint5_label = ttk.Label(self,text=str("Turpoint 5:"))
self.pilot_mass_label = ttk.Label(self,text=str("Pilot Weight:"))

以及在线179：

更改此：

self.main_frame.grid(列=0,行=0)

至：

self.main_frame.grid（列=1，行=0）
