PySide6实时检测剪贴板(QClipboard)并更新文本

注意事项

代码已经在Windows 10 工作站版与Linux Gnome环境上做过测试
差异Windows10工作站版运行代码无法读取上一次剪贴板内容(程序运行以后，可以获取)

代码示例

单行文本框 `QLineEdit`实现

py 复制代码

# coding = utf-8

from PySide6.QtWidgets import QMainWindow,QLineEdit,QApplication
from PySide6.QtGui import QGuiApplication
import sys

class TestCliboard(QMainWindow):
    def __init__(self):
        super().__init__()
        self.setupUi()

    def setupUi(self):
        self.setWindowTitle("实时检测并更新文本")
        self.resize(400,300)

        # 实例化 剪贴板对象
        self.clipboard = QGuiApplication.clipboard()
        
        # 嵌入单行文本
        self.lineText =  QLineEdit()
        self.setCentralWidget(self.lineText)

        # 触发剪贴板数据改变信号时更新文本
        self.clipboard.dataChanged.connect(self.updateText)

    
    def updateText(self):
        clipboardText = self.clipboard.text()
        if clipboardText:
            self.lineText.setText(clipboardText)
        else:
            self.lineText.setText("剪贴板内没有文本！")




if __name__ == "__main__":
    app = QApplication(sys.argv)
    testCliboard = TestCliboard()
    testCliboard.show()
    sys.exit(app.exec())

标签`QLabel`实现

py 复制代码

# coding = utf-8
# coding = utf-8
from PySide6.QtWidgets import QWidget,QLabel,QVBoxLayout,QApplication
from PySide6.QtGui import QGuiApplication
import sys

class BoardText(QWidget):

    def __init__(self):
        super().__init__()
        self.setupUi()

    def setupUi(self):
        self.setWindowTitle("更新与显示剪贴板内容")
        self.resize(400,100)

        vbox = QVBoxLayout(self)
        self.textLable =  QLabel(self)
        vbox.addWidget(self.textLable)
        
        self.clipboard_ = QGuiApplication.clipboard()
        self.clipboard_.dataChanged.connect(self.updateLabelText)
        
    def updateLabelText(self):
        mimeData_ = self.clipboard_.mimeData()
        hasText = mimeData_.hasText()
        clipboardText = mimeData_.text()

        if hasText:
            self.textLable.setText(clipboardText)
        else:
            self.textLable.setText("剪贴板内没有文本！")


if __name__ == "__main__":
    app = QApplication(sys.argv)
    boardText = BoardText()
    boardText.show()
    sys.exit(app.exec())
