pyside6总结

参考

1. Learn Python GUI Development for Desktop – PySide6 and Qt Tutorial

说明

1. PySide6编程可以分为两大类：QWidget 和 QML!

代码模块化

1. main.py

import sys
from PySide6.QtWidgets import QApplication
from button_holder import ButtonHolderif __name__ == "__main__":app = QApplication(sys.argv)window = ButtonHolder()window.show()app.exec()

2. button_holder.py

from PySide6.QtWidgets import QMainWindow, QPushButton, QVBoxLayoutclass ButtonHolder(QMainWindow):def __init__(self):super().__init__()self.setWindowTitle("Button Holder")button = QPushButton("Click Me")button.setCheckable(True)   # must for triggering toggledbutton.clicked.connect(self.on_click1)button.clicked.connect(self.on_click2)button.pressed.connect(self.on_press)button.released.connect(self.on_release)button.toggled.connect(self.on_toggled)   self.setCentralWidget(button)def on_click1(self):print("Button clicked")def on_click2(self, state: bool):  # seems same with toggledprint("Button clicked:", state)def on_press(self):print("Button pressed")def on_release(self):print("Button released")def on_toggled(self, state: bool):  # only triggered by checkable buttonprint("Button toggled:", state)

QMainWindow和QWidget区别

1. QMainWindow比QWidget多了菜单栏，工具栏，状态栏；
2. 在向主窗体添加元素(比如按钮)时，QMainWindow可以直接通过setCentralWidget()实现；而QWidget需要通过Layout间接实现；

通过Label显示图片

将UI文件编译成Python文件

1. 在Qt Designer的Resource Browser里面创建一个资源文件，然后在资源文件中添加需要显示的图片；
2. 在Qt Designer添加一个QLabel，在其pixmap属性中添加图片；
3. 通过pyside6-rcc.exe -o image_rc.py .\image.qrc将资源文件编译成py文件；(注意命名规则：必须是xxx_rc.py，xxx是第一步中创建的资源文件的文件名)
4. 通过pyside6-uic.exe -o ui_test.py .\test.ui将UI文件编译成py文件；
5. 通过以下代码导入UI：

from PySide6.QtWidgets import QApplication, QWidget
from ui_test import Ui_Form     # ui_test 参考步骤4中生成的文件名； Ui_Form 参考 ui_test.py 文件中的类名；class MainWindow(QWidget, Ui_Form):def __init__(self):super().__init__()self.setupUi(self)app = QApplication([])
window = MainWindow()
window.show()
app.exec()

直接导入UI文件

1. 在Qt Designer的Resource Browser里面创建一个资源文件，然后在资源文件中添加需要显示的图片；
2. 在Qt Designer添加一个QLabel，在其pixmap属性中添加图片；

复选框和单选框

1. widget.py

from PySide6.QtWidgets import QWidget, QCheckBox, QRadioButton, QHBoxLayout, QVBoxLayout, QGroupBox, QButtonGroupclass Widget(QWidget):def __init__(self):super().__init__()os = QGroupBox("Choose operating system")win = QCheckBox("Windows")win.clicked.connect(self.win_checked)win.setChecked(True)linux = QCheckBox("Linux")mac = QCheckBox("Mac")os_layout = QVBoxLayout()os_layout.addWidget(win)os_layout.addWidget(linux)os_layout.addWidget(mac)os.setLayout(os_layout)drink = QGroupBox("Choose your favorite drink")beer = QCheckBox("Beer")beer.toggled.connect(self.beer_checked)juice = QCheckBox("Juice")coffee = QCheckBox("Coffee")beer.setChecked(True)exclusive_btn = QButtonGroup(self)  # must selfexclusive_btn.addButton(beer)exclusive_btn.addButton(juice)exclusive_btn.addButton(coffee)exclusive_btn.setExclusive(True)# exclusive_btn.buttonClicked.connect(self.exclusive_checked)drink_layout = QVBoxLayout()drink_layout.addWidget(beer)drink_layout.addWidget(juice)drink_layout.addWidget(coffee)drink.setLayout(drink_layout)answer = QGroupBox("Answer")answerA = QRadioButton("A")answerA.clicked.connect(self.answerA_checked)answerB = QRadioButton("B")answerC = QRadioButton("C")answer_layout = QVBoxLayout()answer_layout.addWidget(answerA)answer_layout.addWidget(answerB)answer_layout.addWidget(answerC)answer.setLayout(answer_layout)h_layout = QHBoxLayout()h_layout.addWidget(os)h_layout.addWidget(drink)v_layout = QVBoxLayout()v_layout.addLayout(h_layout)v_layout.addWidget(answer)self.setLayout(v_layout)def win_checked(self):if self.sender().isChecked():print("Windows is checked")def beer_checked(self):if self.sender().isChecked():print(self.sender().text() + " is checked")def answerA_checked(self):if self.sender().isChecked():print(self.sender().text() + " is checked")def exclusive_checked(self):	# How to get the sender info?print(self.sender())

2. main.py

import sys
from PySide6.QtWidgets import QApplication
from widget import Widgetapp = QApplication(sys.argv)
window = Widget()
window.show()
app.exec()
