Question

我正在编写一个python脚本，可以显示我选择标签的按钮。

该程序包含4个radiobutton和1个标签。

到目前为止我的程序问题是我的程序无法重复。此外，我需要在标签周围设置边框。

我正在使用python 2.7而且我无法发布图片，因为我没有足够的声誉

= Label(the_window, text = 'Null', fg = 'black',font = ('Times', 36), width = 8)
button.grid(row=2,column=1)
button.grid(row=3,column=1)
button.grid(row=2,column=2)
button.grid(row=3,column=2)

这是我的设置

您可以通过指定relief：

为标签添加边框

direction_status = Label(the_window, text = 'Null', fg = 'black',
                         font = ('Times', 36), width = 8, relief=GROOVE)

使用单个IntVar，而不是将四个BooleanVars用作单选按钮的value属性。这将向Tkinter表明单选按钮属于同一组，并确保一次只能选择一个。

from Tkinter import *

# Create a window
the_window = Tk()

# Give the window a title
the_window.title('Compass')

##Label widget to display initial Compass's status
direction_status = Label(the_window, text = 'Null', fg = 'black',
                         font = ('Times', 36), width = 8)

## Function that define the label's text when radiobuttion is being selected
def update_the_window():
    if v.get() == 1:
        direction_status['text'] = 'NW'
    if v.get() == 2:
        direction_status['text'] = 'SW'
    if v.get() == 3:
        direction_status['text'] = 'NE'
    if v.get() == 4:
        direction_status['text'] = 'SE'

## Label Frame for direction_status
direction_status_frame = LabelFrame(the_window, relief = 'groove',
                             borderwidth = 2)


v = IntVar()
## 4 Buttons that change the status sorted by directions
NW_button = Radiobutton(text = 'North-West', variable = v,
                        value= 1, command=update_the_window, padx=20)
NW_button.pack(anchor=W)

SW_button = Radiobutton(text = 'South-West', variable = v,
                        value= 2, command = update_the_window, padx=20)
SW_button.pack(anchor=W)

NE_button = Radiobutton(text= 'North-East', variable = v,
                        value= 3, command=update_the_window, padx=20)
NE_button.pack(anchor=W)

SE_button = Radiobutton(text= 'South-East', variable = v,
                        value= 4, command=update_the_window, padx=20)
SE_button.pack(anchor=W)

## Grid geometry to put 4 radio buttons into the GUI
NW_button.grid(row=2,column=1)
SW_button.grid(row=3,column=1)
NE_button.grid(row=2,column=2)
SE_button.grid(row=3,column=2)

## Grid geometry manager to put the widget into the root window
margin = 5 ##pixels
direction_status.grid(padx=margin, pady=margin, row=1, column=1, columnspan=2)

# Start the event loop to react to user inputs
the_window.mainloop()

您也可以使用StringVar，这会在一定程度上减少update_the_window的大小。

from Tkinter import *

# Create a window
the_window = Tk()

# Give the window a title
the_window.title('Compass')

# PUT YOUR CODE HERE-------------------------------------------------#

##Label widget to display initial Compass's status
direction_status = Label(the_window, text = 'Null', fg = 'black',
                         font = ('Times', 36), width = 8)




## Function that define the label's text when radiobuttion is being selected
def update_the_window():
    direction_status['text'] = direction.get()

direction = StringVar()
direction.set("NW")
update_the_window()

## Label Frame for direction_status
direction_status_frame = LabelFrame(the_window, relief = 'groove',
                             borderwidth = 2)


## 4 Buttons that change the status sorted by directions
NW_button = Radiobutton(text = 'North-West', variable = direction,
                        value= "NW", command=update_the_window, padx=20)
NW_button.pack(anchor=W)

SW_button = Radiobutton(text = 'South-West', variable = direction,
                        value= "SW", command = update_the_window, padx=20)
SW_button.pack(anchor=W)

NE_button = Radiobutton(text= 'North-East', variable = direction,
                        value= "NE", command=update_the_window, padx=20)
NE_button.pack(anchor=W)

SE_button = Radiobutton(text= 'South-East', variable = direction,
                        value= "SE", command=update_the_window, padx=20)
SE_button.pack(anchor=W)

## Grid geometry to put 4 radio buttons into the GUI
NW_button.grid(row=2,column=1)
SW_button.grid(row=3,column=1)
NE_button.grid(row=2,column=2)
SE_button.grid(row=3,column=2)

## Grid geometry manager to put the widget into the root window
margin = 5 ##pixels
direction_status.grid(padx=margin, pady=margin, row=1, column=1, columnspan=2)

# Start the event loop to react to user inputs
the_window.mainloop()

Radionbutton输出复位和边框未显示
