Question

我试图在eclipse上使用Tkinter，它适用于这样的短代码：

from tkinter import *

root = Tk()
mainloop()

此代码适用于eclipse，但这个代码不适用：

from tkinter import Tk, Canvas, HIDDEN, NORMAL

root = Tk()
root.title('Snap')

c = Canvas(root, width=400, height=400)

shapes = []
circle = c.create_oval(35, 20, 365, 350, outline='black', fill='black',
                       state=HIDDEN)
shapes.append(circle)
circle = c.create_oval(35, 20, 365, 350, outline='red', fill='red',
                       state=HIDDEN)
shapes.append(circle)
circle = c.create_oval(35, 20, 365, 350, outline='green', fill='green',
                       state=HIDDEN)
shapes.append(circle)
circle = c.create_oval(35, 20, 365, 350, outline='blue', fill='blue',
                       state=NORMAL)
shapes.append(circle)
c.pack()

此代码应该显示一个窗口并且上面有一个蓝色圆圈，但我尝试运行它但没有任何反复发生。

最后添加<?xml version="1.0" encoding="utf-8"?> <android.support.v7.widget.CardView xmlns:android="http://schemas.android.com/apk/res/android" xmlns:card_view="http://schemas.android.com/tools" android:id="@+id/my_cardview" android:layout_width="wrap_content" android:layout_height="wrap_content"> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical"> <TextView android:id="@+id/cardview_titleA" android:layout_width="match_parent" android:layout_height="wrap_content" /> <ImageView android:id="@+id/image_pictogram" android:layout_width="match_parent" android:layout_height="wrap_content"/> <TextView android:id="@+id/cardview_titleB" android:layout_width="match_parent" android:layout_height="wrap_content" /> </LinearLayout> </android.support.v7.widget.CardView>，如下所示：

root.mainloop()

或者在导入中包含from tkinter import Tk, Canvas, HIDDEN, NORMAL root = Tk() root.title('Snap') c = Canvas(root, width=400, height=400) shapes = [] circle = c.create_oval(35, 20, 365, 350, outline='black', fill='black', state=HIDDEN) shapes.append(circle) circle = c.create_oval(35, 20, 365, 350, outline='red', fill='red', state=HIDDEN) shapes.append(circle) circle = c.create_oval(35, 20, 365, 350, outline='green', fill='green', state=HIDDEN) shapes.append(circle) circle = c.create_oval(35, 20, 365, 350, outline='blue', fill='blue', state=NORMAL) shapes.append(circle) c.pack() root.mainloop()并运行mainloop而不是mainloop()

Pydev Eclipse上的Tkinter不起作用
