Question

这是图像的一部分。

    from tkinter import *

class Application(Frame):
    """GUI application which counts button clicks."""
    def __init__(self, master):
        super(Application, self).__init__(master)
        self.grid()
        self.bttn_clicks = 0
        self.create_widget()

    def create_widget(self):
        """ Create buttong that displays the number of clicks. """
        self.bttn = Button(self)
        self.bttn["text"]= "Total Clicks: 0"
        self.bttn["command"] = self.update_count
        self.bttn.grid()

    def update_count(self):
        """ Increase click count and display new total. """
        self.bttn_clicks += 1
        self.bttn["text"] = "Total Clicks: " + str(self.bttn_clicks)

#main
root = Tk()
root.title("Click Counter")
root.geometry("300x115")

app = Application(root)

任何想法我怎么能这样做？

您将比背景图像规则更多地使用背景规则。通过简写，您将能够控制其背景颜色，如果由于没有互联网连接而无法加载图像，并且您还可以控制您希望图像重复与否，滚动或保持固定等等。

试试这个：

.wrapper {      
    background:url('http://www.intrawallpaper.com/static/images/gradient-background.jpg') center center no-repeat fixed;
    background-size: cover;
}
