PySide2|PySide6安装使用及QT Designer UI设计 PySide2|python

安装pyside6

>>> pip install pyside6

查看QT Designer程序

>>> pip show pyside6Location: c:\users\Administrator\...\python\python39\site-packages//若上述代码运行报错 >>> where python C:\...\Python\Python39\python.exepython文件夹内搜索 C:\...\Python\Python39\site-packages\PySide6\designer.exe

Ⅰ. Init

from PySide6.QtWidgets import *class Window: def __init__(self): self.win = QMainWindow()if __name__ == '__main__': app = QApplication([]) w = Window() w.win.show() app.exec_()

from PySide6.QtWidgets import *if __name__ == '__main__': app = QApplication([]) win = QMainWindow() win.show() app.exec_()

Ⅱ Example

from PySide6.QtWidgets import *class Window: def __init__(self): self.win = QMainWindow() self.win.resize(500, 400) self.win.move(700, 210) self.win.setWindowTitle("测试窗口")self.textEdit = QTextEdit(self.win) self.textEdit.move(50, 50) self.textEdit.resize(200, 300) self.textEdit.setPlaceholderText("请输入文本")self.button = QPushButton("button", self.win) self.button.move(300, 100) self.button.clicked.connect(self.btnClick)def btnClick(self): info = self.textEdit.toPlainText()# 获取文本信息 print(info) # print("button被点击")if __name__ == '__main__': app = QApplication([]) # win = QMainWindow() # win.show() w = Window() w.win.show() app.exec_()

【PySide2|PySide6安装使用及QT Designer UI设计】QT Designer
1.自动生成python代码

... from PySide6.QtCore import QFile from PySide6.QtUiTools import QUiLoader...if __name__ == "__main__": app = QApplication([]) win = QMainWindow() w = Ui_Form() w.setupUi(win) win.show() app.exec_()

view python code 报错："Unable to lanch C" -> PySide6文件夹下复制uic.exe到新建的bin文件夹内C:\...\Python\Python39\site-packages\PySide6\bin\uic.exe

2.动态加载ui文件（首选）

from PySide6.QtWidgets import * from PySide6.QtCore import QFile from PySide6.QtUiTools import QUiLoaderclass Window: def __init__(self): super(Window, self).__init__() # 从ui文件中加载UI定义 qfile = QFile("demo1.ui") qfile.open(QFile.ReadOnly) qfile.close() # 从UI定义中动态创建一个相应的窗口对象 self.ui = QUiLoader().load(qfile)# 信号处理 self.ui.button.clicked.connect(self.btnClick) # self.button.clicked.connect(self.btnClick)def btnClick(self): info = self.ui.textEdit.toPlainText()# 获取文本信息 # info = self.textEdit.toPlainText() print(info)if __name__ == '__main__': app = QApplication([]) # app.setWindowIcon(QIcon("logo.png"))# 添加图标 w = Window() w.ui.show() # w.win.show() app.exec_()

最后：发布QT程序

>>> pip install pyinstaller>>> pyinstaller *.py --noconsole --hidden-import PySide6.QtXml [--icon="logo.ico"]并将ui文件移至dist文件夹内
