在python上添加标签

Question

我想在标签上创建框架并尝试了很多代码，但它没有成功。还试图在没有框架的情况下在屏幕左侧制作检查按钮。谁能帮我？谢谢

我走得很远

但我希望用框架

使它看起来像这样

show_status = Label(dashboard, bd = 5, text = 'Even', fg = 'black',
                        font = ('Arial', 70), width = 8)

def update_dashboard():

three_buttons = Label(dashboard, relief = 'groove')

Alpha_button = Checkbutton(three_buttons, text = 'Alpha',
                              variable = alpa_1,
                              command = update_dashboard)

Beta_button = Checkbutton(three_buttons, text = 'Beta',
                           variable = beta_2, 
                           command = update_dashboard)

Gamma_button = Checkbutton(three_buttons, text = 'Gamma',
                           variable = gemma_3, 
                           command = update_dashboard)


Alpha_button.grid(row = 1, column = 0, sticky = 'w')
Beta_button.grid(row = 1, column = 2, sticky = 'w')
Gamma_button.grid(row = 1, column = 4, sticky = 'w')

margin = 5 # pixels

show_status.grid(padx = margin, pady = margin, row = 1,
                     column = 1, columnspan = 2,)
three_buttons.grid(row = 4, column = 2, sticky = W)


dashboard.mainloop()

Answer 1

您可以使用Frame或Canvas并在其上绘制其余小部件。让我们依靠grid layout manager来使用框架。

要获得您正在寻找的效果，您只需使用columnspan选项选项将标签跨越检查按钮小部件的3列。

这是一个使用面向对象概念的简单解决方案：
