【问题描述】：

我想连接 wpfcode 和 Ironpython。但我不知道如何使用 xaml 和 py 文件之间的数据绑定。我该怎么办？

XAML：

<Window 
       xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
       xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
       Title="WpfApplication9" Height="300" Width="300">
    <Grid>
        <TextBlock Text="{Binding Path=time1()}" HorizontalAlignment="Left" Margin="10,117,0,0" TextWrapping="Wrap"  VerticalAlignment="Top" Width="272"/>
    </Grid>
</Window>

import wpf
import time
from System.Windows import Application, Window
from time import localtime
class MyWindow(Window):

        def __init__(self):
        wpf.LoadComponent(self, 'test.xaml')
        self.TextBlock.Text = time1()

    def time1():
        now = time.localtime()
        setime = "%02d%02d%02d" % (now.tm_hour, now.tm_min, now.tm_sec)

        while 1:
            cnow = time.localtime()
            ntime = "%02d%02d%02d" % (cnow.tm_hour, cnow.tm_min, cnow.tm_sec)

            if int(ntime) != int(setime):
                realtime = "%02d:%02d:%02d" % (cnow.tm_hour, cnow.tm_min, cnow.tm_sec)

                print realtime
                setime = ntime
if __name__ == '__main__':
Application().Run(MyWindow())
time1()

【问题讨论】：

你看过answers like this或articles like this吗？这一切都暗示使用 INotifyPropertyChanged。

【解决方案1】：

你应该再次绑定属性：

<Window 
       xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" 
       xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" 
       Title="WpfApplication9" Height="300" Width="300">
    <Grid>
        <TextBlock Text="{Binding SomeMemer, Mode=TwoWay}" HorizontalAlignment="Left" Margin="10,117,0,0" TextWrapping="Wrap"  VerticalAlignment="Top" Width="272"/>
    </Grid>
</Window>

import wpf
import time
from System.Windows import Application, Window
from time import localtime
class MyWindow(Window):

    someMember = None   

    def __init__(self):
    wpf.LoadComponent(self, 'test.xaml')
    self.someMember = "Hello World"

    @property
    def SomeMember(self):
        return self.someMember 

    @psetter.SomeMember
    def SomeMember(self, value):
        self.someMember = value 


if __name__ == '__main__':
Application().Run(MyWindow())
time1()
