In this PyQt5 tutorial i want to show you How To Draw Texts in PyQt5. so we are going to use QPainter class for drawing Texts. the QPainter class performs low-level painting on widgets and other paint devices. QPainter provides highly optimized functions to do most of the drawing GUI programs require. It can draw everything from simple lines to complex shapes like pies and chords. It can also draw aligned text and pixmaps.

from PyQt5 import QtGui from PyQt5.QtWidgets import QApplication, QMainWindow from PyQt5.QtGui import QPainter, QTextDocument from PyQt5.QtCore import QRect, Qt, QRectF import sys class Window(QMainWindow): def __init__(self): super().__init__() self.title = "PyQt5 Drawing Text" self.top = 200 self.left = 500 self.width = 400 self.height = 300 self.InitWindow() def InitWindow(self): self.setWindowIcon(QtGui.QIcon("icon.png")) self.setWindowTitle(self.title) self.setGeometry(self.left, self.top, self.width, self.height) self.show() def paintEvent(self, event): painter = QPainter(self) painter.drawText(100,100, "Hello PyQt5 App Development") rect = QRect(100,150, 250,25) painter.drawRect(rect) painter.drawText(rect, Qt.AlignCenter, "Hello World") document = QTextDocument() rect2 = QRectF(0,0,250,250) document.setTextWidth(rect2.width()) document.setHtml("<b>Python GUI </b> <i> Development </i> <font size = '10' color='red'>Complete Series</font>") document.drawContents( painter, rect2) App = QApplication(sys.argv) window = Window() sys.exit(App.exec()) |
This is our main window class that extends from QMainWindow and we initialize some requirements for the window in this class, also we have called our InitWindow() method
in here.

class Window(QMainWindow): def __init__(self): super().__init__() self.title = "PyQt5 Drawing Text" self.top = 200 self.left = 500 self.width = 400 self.height = 300 self.InitWindow() |
This is the method that we set our window requirements like icon, title, width and height
that we have before created in the constructor of our main class.

def InitWindow(self): self.setWindowIcon(QtGui.QIcon("icon.png")) self.setWindowTitle(self.title) self.setGeometry(self.left, self.top, self.width, self.height) self.show() |
So now this is our PaintEvent() method, this is method is related to our QPainter class and when we want to do drawing in PyQt5 we need to use this method.and we create our Texts using painter.drawText() that takes two arguments the first one is the x and y position and the second one is the text it self that we want to draw.

def paintEvent(self, event): painter = QPainter(self) painter.drawText(100,100, "Hello PyQt5 App Development") rect = QRect(100,150, 250,25) painter.drawRect(rect) painter.drawText(rect, Qt.AlignCenter, "Hello World") document = QTextDocument() rect2 = QRectF(0,0,250,250) document.setTextWidth(rect2.width()) document.setHtml("<b>Python GUI </b> <i> Development </i> <font size = '10' color='red'>Complete Series</font>") document.drawContents( painter, rect2) |
The QTextDocument class holds formatted text.QTextDocument is a container for structured rich text documents, providing support for styled text and various types of document elements, such as lists, tables, frames, and images. They can be created for use in a QTextEdit, or used independently.

document = QTextDocument() rect2 = QRectF(0,0,250,250) document.setTextWidth(rect2.width()) document.setHtml("<b>Python GUI </b> <i> Development </i> <font size = '10' color='red'>Complete Series</font>") document.drawContents( painter, rect2) |
Run the complete code and this will be the result.
