如何将Qt Designer完成的设计与PyCharm中Python3.6.4及PyQt5关联

Hey Tariq, let's get your Qt Designer setup linked with PyCharm and Python 3.6.4 smoothly. Since you've already got PyQt5 installed, here's a step-by-step guide to tie everything together:

• Open PyCharm and head to File > Settings (or PyCharm > Preferences if you're on macOS).
• Navigate to Project: [Your Project Name] > Python Interpreter.
• Click the gear icon ⚙️ and select Add.
• Choose System Interpreter, then locate your Python 3.6.4 installation path — based on your pip output, it should be C:\Users\Tariq\AppData\Local\Programs\Python\Python36-32\python.exe.
• Select this path and click OK to set it as your project's interpreter. This ensures PyCharm uses the exact Python version where you installed PyQt5.

• Stay in Settings and go to Tools > External Tools.
• Click the + button to add a new external tool.
• Fill in these details:
  • Name: Qt Designer
  • Program: Find the designer.exe file in your PyQt5 folder. It’s typically at C:\Users\Tariq\AppData\Local\Programs\Python\Python36-32\Lib\site-packages\PyQt5\Qt\bin\designer.exe
  • Arguments: Leave this blank
  • Working directory: $ProjectFileDir$ (this makes Designer open files relative to your project folder)
• Click Apply then OK to save. Now you can launch Qt Designer directly from PyCharm via Tools > External Tools > Qt Designer.

After designing your UI in Qt Designer and saving it as a .ui file, you need to convert it to Python code to use it in your project. Here’s how to set up the converter tool:

• Go back to Tools > External Tools and click + again.
• Fill in:
  • Name: PyUIC
  • Program: Your Python 3.6.4 python.exe path (same as before: C:\Users\Tariq\AppData\Local\Programs\Python\Python36-32\python.exe)
  • Arguments: -m PyQt5.uic.pyuic $FileName$ -o $FileNameWithoutExtension$.py
  • Working directory: $FileDir$
• Save this tool. Now, right-click your .ui file in PyCharm, go to External Tools > PyUIC, and it’ll generate a corresponding .py file with your UI code.

In your main Python script, you can import the generated UI class and use it like this:

import sys
from PyQt5.QtWidgets import QApplication, QMainWindow
from your_ui_file_name import Ui_MainWindow  # Replace with your actual UI class name

class MainWindow(QMainWindow, Ui_MainWindow):
    def __init__(self):
        super().__init__()
        self.setupUi(self)
        # Add your custom functionality here

if __name__ == "__main__":
    app = QApplication(sys.argv)
    window = MainWindow()
    window.show()
    sys.exit(app.exec_())

Just make sure the generated .py file is in the same directory as your main script, or adjust the import path if needed.
