[英]Python 2.7 Tkinter widgets not showing
I'm working on setting up a Tkinter app, for some reason, the basic widgets aren't showing. 我正在设置Tkinter应用程序,由于某种原因,基本的小部件没有显示。 I'm getting a blank Tkinter window, and nothing else.
我得到一个空白的Tkinter窗口,仅此而已。
The following is my code. 以下是我的代码。 I've tried adding simple widgets, and that's not working.
我尝试添加简单的小部件,但这没有用。
Here's the code I have: 这是我的代码:
import Tkinter as Tk
import ttk as ttk
class MainApplication(Tk.Frame):
def __init__(self, root):
Tk.Frame.__init__(self)
self.root = root
self.root.title('JRSuite')
root.attributes('-fullscreen', True)
self.mainWindow = Tk.Frame(self)
self.mainWindow.pack()
self._windowSetup()
def _windowSetup(self):
'''Sets up the basic components of the main window'''
self.tree = ttk.Treeview(self.mainWindow)
self.tree.pack()
self.note = ttk.Notebook(self.mainWindow)
self.note.pack()
self.tree.insert('', 'end', text = 'Woohoo')
if __name__ == '__main__':
root = Tk.Tk()
app = MainApplication(root)
app.mainloop()
You ought to pack
the app: 您应该
pack
该应用程序:
if __name__ == '__main__':
root = Tk.Tk()
app = MainApplication(root)
app.pack()
app.mainloop()
Question : Tkinter widgets not showing
问题 :Tkinter小部件未显示
Instead of inheriting from Tk.Frame
inherit from Tk.Tk
which is the root
window. 而不是从
Tk.Frame
继承,而从Tk.Tk
它是root
窗口)继承。
Change to: 改成:
import Tkinter as Tk
import ttk as ttk
class MainApplication(Tk.Tk):
def __init__(self):
Tk.Frame.__init__(self)
self.title('JRSuite')
self.attributes('-fullscreen', True)
self.mainWindow = Tk.Frame(self)
self.mainWindow.pack()
self._windowSetup(self.mainWindow)
def _windowSetup(self, parent):
'''Sets up the basic components of the main window'''
self.tree = ttk.Treeview(parent)
self.tree.pack()
self.note = ttk.Notebook(parent)
self.note.pack()
self.tree.insert('', 'end', text = 'Woohoo')
if __name__ == '__main__':
MainApplication().mainloop()
