In this lesson we want to learn about Python PySide6 QPrintDialog, PySide6 provides QPrintDialog class that simplifies the process of printing documents. in this lesson we are going to cover the basics of using QPrintDialog in PySide6 application.
Introduction to QPrintDialog
QPrintDialog is dialog box that allows user to select printer, configure printing options and initiate printing of document. when the user closes the dialog, QPrintDialog provides the selected printer and printing options to your application.
This is simple example that demonstrates how to use QPrintDialog in PySide6:
from PySide6.QtWidgets import QApplication, QMainWindow, QTextEdit
from PySide6.QtGui import QAction
from PySide6.QtPrintSupport import QPrintDialog
# create QTextEdit widget to display the document
self.textEdit = QTextEdit(self)
# create "Print" action and connect it to the print function
printAction = QAction('Print', self)
# add the "Print" action to the file menu
fileMenu = self.menuBar().addMenu('File')
# set the window title and size
self.setWindowTitle('Print Dialog Example')
self.setGeometry(300, 300, 350, 300)
# create a QPrintDialog instance and execute it
printDialog = QPrintDialog()
if printDialog.exec() == QPrintDialog.Accepted:
# if the user accepts, print the document
if __name__ == '__main__':
app = QApplication(sys.argv)
ex = Example()
In this example we have create new QTextEdit widget and set it as the central widget of our main window. we also create Print action that is added to the File menu and connect it to custom print() function.
When user clicks the Print action, print() creates new QPrintDialog instance and displays it to the user. if the user accepts the dialog, the QTextEdit.print() method is called with the selected printer, which initiates the printing of the document.
Run the complete code and this will be the result.
QPrintDialog class provides an easy way to allow users to print documents from your PySide6 application. with its simple API and built-in support for selecting printers and printing options, QPrintDialog can greatly simplify the process of printing for both you and your users.
