1. 依賴包
Click (7.0) PyQt5 (5.11.2) PyQt5-sip (4.19.12) QScintilla (2.10.7) pip (9.0.1) pyqt5-tools (5.11.2.1.3rc8) 提供了QtDesigner.exe工具 python-dotenv (0.9.1) setuptools (28.8.0) sip (4.19.8)
這些依賴包都能夠通過pip3 install *.whl 的包格式來安裝。

2. PyCharm配置
請參考:https://www.cnblogs.com/BlueSkyyj/p/8398277.html
簡略步驟說明:
- 添加 External Tools:QtDesigner
- 添加 External Tools:PyUIC(QtDesigner生成的.ui文件自動轉換為.py文件)
2.1. External Tools: QtDesigner
Settings -> Tools -> External Tools 選中“+”,彈出的對話框: Name: QtDesigner Tool Settings: Program: C:\Python365\Lib\site-packages\pyqt5_tools\designer.exe Parameters: $FileDir$ (這是一個宏,可以通過點擊Insert macro來添加這個值,手動輸入也是一樣的意思) Working directory: $FileDir$
2.2. External Tools: PyUIC
settings -> Tools -> External Tools 選中“+”,彈出的對話框: Name: PyUIC Tool settings: Program: C:\Python365\python.exe Parameters: -m PyQt5.uic.pyuic $FileName$ -o $FileNameWithoutExtension$.py Working directory: $FileDir$ (可以通過 insert macro來設置,也可以手動輸入)
3. 示例
創建一個純python工程(Pure Python Project)QtTest。
3.1. 啟動QtDesigner.exe
通過右鍵 -> External Tools -> QtDesigner,將啟動QtDesigner.exe,創建一個MainWindow,然后將左側的一個 PushButton 拖入 創建的MainWindow,保存文件到工程目錄,取名 hello.ui
3.2. UI轉換為PY
選中 hello.ui,然后右鍵 -> External Tools -> PyUIC,將自動把 hello.ui 轉換為 hello.py 文件了。
3.3. 編寫 main.py
在工程目錄中創建 main.py 文件,寫入如下內容:
import sys import hello #生成的 hello.py from PyQt5.QtWidgets import QApplication, QMainWindow if __name__ == '__main__': app = QApplication(sys.argv) w = QMainWindow() ui = hello.Ui_MainWindow() ui.setUi(w) w.show() sys.exit(app.exec_())
3.4. 運行
main.py 文件內,點擊鼠標右鍵,選擇:Run,將彈出一個 Window 窗口。
3.5. 不啟動后台
使用 pythonw.exe 運行 GUI 程序,將不顯示 cmd 窗口,只會顯示 GUI 窗口,這點非常的有用,但是這個解析器同時關閉了原來的:stdin, stdout, stderr。解決方案參考鏈接:https://stackoverflow.com/questions/9705982/pythonw-exe-or-python-exe

# 來自 《PyQt5 快速開發與實踐》 import sys from PyQt5.QtWidgets import QPushButton, QApplication, QWidget class WinForm(QWidget): def __init__(self, parent=None): super(WinForm, self).__init__(parent) self.setGeometry(300, 300, 350, 350) self.setWindowTitle('點擊按鈕關閉窗口') quit = QPushButton('Close', self) quit.setGeometry(10, 10, 60, 35) quit.setStyleSheet("background-color: red") quit.clicked.connect(self.close) if __name__ == '__main__': app = QApplication(sys.argv) win = WinForm() win.show() sys.exit(app.exec_())
