python - 使用 python 设置背景图像

Question

import wpf

from System.Windows import Application, Window,MessageBox
from Main import *
from Sign_Up import *

import System
from System.Windows.Controls import *
from System.Windows.Input import *
from System import Uri
from System.Windows.Media.Imaging import BitmapImage
from System.Windows.Media import ImageBrush

class MyWindow(Window):
    def __init__(self):
        wpf.LoadComponent(self, 'Sign_In.xaml')
        brush = ImageBrush()
        image = Image()
        image.Source = BitmapImage(Uri("C:\Users\Chen\Pictures\1-150511225359.jpg"))
        brush.ImageSource = image.Source
        self.SignUpGrid.Background = brush

我尝试在 wpf IronPython 中设置窗口的背景图像，但不断出现语法错误。

您应该在路径名中使用双\。而且您不需要中间的 Image 控件。

def __init__(self):
    wpf.LoadComponent(self, 'Sign_In.xaml')
    brush = ImageBrush()
    brush.ImageSource = BitmapImage(Uri("C:\\Users\\Chen\\Pictures\\1-150511225359.jpg"))
    self.SignUpGrid.Background = brush

或者更短:

def __init__(self):
    wpf.LoadComponent(self, 'Sign_In.xaml')
    self.SignUpGrid.Background = ImageBrush(BitmapImage(Uri(
        "C:\\Users\\Chen\\Pictures\\1-150511225359.jpg")))
