PyQt:将 date/time 编译成 window 标题

PyQt: Compiling date/time into window title

如何把编译的date/time放到window标题中? 下面的示例(当然)将不起作用,因为它会在程序启动时将日期和时间放入标题中。 好吧,每次编译新版本时,我都可以在源代码中手动输入日期和时间。但是,我希望有一个智能和自动化的解决方案。有什么想法吗?

代码:

import sys
from datetime import datetime
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QMessageBox 

class MyWindow(QWidget):
    def __init__(self):
        super(MyWindow,self).__init__()
        self.setGeometry(100,100,400,200)
        self.setWindowTitle('Version ' + datetime.now().strftime("%Y%m%d-%H%M"))
        # define button1 
        self.button1 = QPushButton('Push me',self)
        self.button1.move(100,100)
        self.button1.setStyleSheet("background-color: #ddffdd")
        self.button1.clicked.connect(self.button1_clicked)

    def button1_clicked(self):
        msg = QMessageBox()
        msg.setText("This is a message box")
        msg.exec_()

if __name__ == '__main__':
    app = QApplication(sys.argv)
    app.setStyle("plastique")
    window = MyWindow()
    window.show()
    sys.exit(app.exec_())

编译者:

pyinstaller --onefile tbMinimalPyQt5.py

.spec 文件

# -*- mode: python -*-

block_cipher = None


a = Analysis(['tbMinimalPyQt5.py'],
             pathex=['C:\User\Test'],
             binaries=[],
             datas=[],
             hiddenimports=[],
             hookspath=[],
             runtime_hooks=[],
             excludes=[],
             win_no_prefer_redirects=False,
             win_private_assemblies=False,
             cipher=block_cipher)
pyz = PYZ(a.pure, a.zipped_data,
             cipher=block_cipher)
exe = EXE(pyz,
          a.scripts,
          a.binaries,
          a.zipfiles,
          a.datas,
          name='tbMinimalPyQt5',
          debug=False,
          strip=False,
          upx=True,
          runtime_tmpdir=None,
          console=True )

听起来您可以使用 os.path.getmtime() 获取 EXE 文件的时间戳,然后在 window 标题中报告。唯一脆弱的部分是确保您拥有以绝对方式已知的 EXE 路径...

因此您需要将上面的 datetime.now().strftime("%Y%m%d-%H%M") 调用更改为 time.ctime(os.path.getmtime(EXEFILE))

一个解决方案是在 .spec 中编写一个代码,用数据创建一个 .py:

# -*- mode: python -*-

import datetime

data = {
  "BUILD_DATE": datetime.datetime.now().strftime("%Y%m%d-%H%M")
}

with open('constants.py', 'w') as f:
    for k, v in data.items():
      f.write("{} = \"{}\"\n".format(k, v))

block_cipher = None


a = Analysis(['tbMinimalPyQt5.py'],
             pathex=['C:\User\Test'],
# ...

然后在您的 .py 中使用编译时生成的值导入文件 constants.py:

import sys
from PyQt5.QtWidgets import QApplication, QWidget, QPushButton, QMessageBox 
import constants

class MyWindow(QWidget):
    def __init__(self):
        super(MyWindow,self).__init__()
        self.setGeometry(100,100,400,200)
        self.setWindowTitle('Version ' + constants.BUILD_DATE)
        # define button1 
        self.button1 = QPushButton('Push me',self)
        self.button1.move(100,100)
        self.button1.setStyleSheet("background-color: #ddffdd")
        self.button1.clicked.connect(self.button1_clicked)

    def button1_clicked(self):
        msg = QMessageBox()
        msg.setText("This is a message box")
        msg.exec_()

if __name__ == '__main__':
    app = QApplication(sys.argv)
    app.setStyle("plastique")
    window = MyWindow()
    window.show()
    sys.exit(app.exec_())

最后你使用 .spec 编译:

pyinstaller tbMinimalPyQt5.spec
