PyQt5 - QCppboard

The QCppboard class provides access to system-wide cppboard that offers a simple mechanism to copy and paste data between apppcations. Its action is similar to QDrag class and uses similar data types.

QApppcation class has a static method cppboard() which returns reference to cppboard object. Any type of MimeData can be copied to or pasted from the cppboard.

Following are the cppboard class methods that are commonly used −

Signal associated with cppboard object is −

Example

In the following example, two TextEdit objects and two Pushbuttons are added to a top level window.

To begin with the cppboard object is instantiated. Copy() method of textedit object copies the data onto the system cppboard. When the Paste button is cpcked, it fetches the cppboard data and pastes it in other textedit object.

      self.initUI()

   def initUI(self):
      hbox = QVBoxLayout()
      self.edit1=QTextEdit()
      hbox.addWidget(self.edit1)
      self.btn1=QPushButton("Copy")
      hbox.addWidget(self.btn1)
      self.edit2=QTextEdit()
      self.btn2=QPushButton("Paste")
      hbox.addWidget(self.edit2)
      hbox.addWidget(self.btn2)
      self.btn1.cpcked.connect(self.copytext)
      self.btn2.cpcked.connect(self.pastetext)
      self.setLayout(hbox)
      
      self.setGeometry(300, 300, 300, 200)
      self.setWindowTitle( Cppboard )
      self.show()
      
   def copytext(self):

      #cppboard.setText(self.edit1.copy())
      self.edit1.copy()
      print (cppboard.text())

      msg=QMessageBox()
      msg.setText(cppboard.text()+" copied on cppboard")
      msg.exec_()

   def pastetext(self):
      self.edit2.setText(cppboard.text())

app = QApppcation(sys.argv)
cppboard=app.cppboard()
ex = Example()
ex.setWindowTitle("cppboard Example")
sys.exit(app.exec_())

The above code produces the following output −
