#Port Scanner
class Window2(Frame):
   def __init__(self, parent):
        Frame.__init__(self, parent)
        self.parent = parent
        self.initUI2()

这是我试图放置小部件的框架，但是当我运行它时它什么也没做。我正在使用PyCharm作为我的编辑。尝试制作小部件，以便用户可以与之交互。我想制作一个输入框和一个包含文本＆＃34; run＆＃34;的按钮。它在调试器中没有显示任何内容。

   def initUI2(self):
       self.frame = tk.Frame(self.master)
       self.parent.title("Port Scanner")
       self.parent.geometry("500x300+400+200")
       self.runbutton = Button(self,text="Run")
       self.runbutton.pack()



#Windows Settings
def main():
#<----------------------------------------------------->
    root = Tk()
    root.geometry("500x300+400+100")
    app = Window1(root)
    #Page 1 and Page 2 Tab
    root.mainloop()
#<----------------------------------------------------->

if __name__ == '__main__':
    main()

Answer 1

GUI的全部内容都在窗口app内。但是，您从未使用包，地点或网格将app放在屏幕上，因此它仍然不可见。

由于app似乎是根窗口中唯一的小部件，您可能希望在调用mainloop之前添加此代码：

app.pack(fill="both", expand=True)

Answer 2

在portscanner()方法中，使用pack()在屏幕上显示self.app。

def portscanner(self):
    self.newWindow = tk.Toplevel(self.master)
    self.app = Window2(self.newWindow)
    self.app.pack()
