python用 PythonNet 从 Python 调用 WPF 类库 UI 用XAML

pythonnet 是pythonhe.net通用的神器不多介绍了.  

这次这基本上跟python没有关系了.

和winform一样先导包

import clr
clr.AddReference("PresentationFramework.Classic, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35")
clr.AddReference("PresentationCore, Version=3.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35")
 
from System.Windows import Application
from System.Windows import Window
from System.Windows import MessageBox
from System.Windows import LogicalTreeHelper
from System.Windows.Markup import XamlReader
from System.Threading import Thread
from System.Threading import ApartmentState
from System.Threading import ThreadStart
from System import *
 

哈哈哈 有没有感觉和 C#一样.

using System;
using SC = System.Console;

是不是一模一样;

接下来:  写个类.  当然你可以用C#  VB.net单独做 成DLL也没关系. 重要的是先把婚结了 孩子生出来.  不对 先把东西生产出来.

class MainWindow(Window):
 
  def __init__(self):
    Window.__init__(self)
 
    #  XAML
    xaml = """
    <Page
      xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
      xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
      <Grid>  
      <Grid.RowDefinitions>
        <RowDefinition/>
        <RowDefinition/>
      </Grid.RowDefinitions>
      <Button Name="Button1" Grid.Row="0">Button 1</Button>
      <Button Name="Button2" Grid.Row="1">Button 2</Button>
      </Grid>
    </Page>
    """
    page = XamlReader.Parse(xaml)
 
    # connect Button1
    self.Button1 = LogicalTreeHelper.FindLogicalNode(page, "Button1")
    self.Button1.Click += self.Button1_Click
 
    # connect Button2
    self.Button2 = LogicalTreeHelper.FindLogicalNode(page, "Button2")
    self.Button2.Click += self.Button2_Click
 
    # 
    self.Title = "Python WPF App with XAML!"
    self.Width = 350
    self.Height = 300
    self.Content = page
 
  def Button1_Click(self, sender, e):
    MessageBox.Show(self.Button1.Content + " is clicked!")
 
  def Button2_Click(self, sender, e):
    MessageBox.Show(self.Button2.Content + " is clicked!")

def STAMain():
  app = Application()
  app.Run(MainWindow())
 
def main():
  t = Thread(ThreadStart(STAMain))
  t.ApartmentState = ApartmentState.STA
  t.Start()
  t.Join()
 
if __name__ == "__main__":
  main()

界面一定要线程里面; 要不然python解释器会卡死.

当然 你也可以这么干;用C#界面类库打包写成DLL在用python调用. python只管传参数.

对于性能要求不高的场合就很合适.
