In this PyQt5 article i want to show you how to Create Label & Stylesheets With QLabel In PyQt5. the QLabel widget provides a text or image display. QLabel is used for displaying text or an image.No user interaction functionality is provided.
What is PyQt5 QLabel ?
In PyQt5 QLabel is widget class that provides display area for text or image. it can be used to display text message, an image or both. QLabel can also be used as hyperlink or tool tip. QLabel is part of the QtWidgets module in PyQt5 and is subclass of the QFrame widget. it has different properties and methods that can be used to customize its appearance and behavior. Some of the common properties include:
text: sets or gets the text displayed by the label
pixmap: sets or gets the image displayed by the label
alignment: sets the alignment of the text or image within the label
wordWrap: sets whether the text should be automatically wrapped to fit within the label
sizeHint: returns the recommended size of the label based on its contents

First we need some imports
|
1 2 3 |
from PyQt5.QtWidgets import QApplication, QLabel, QDialog, QVBoxLayout import sys from PyQt5 import QtGui |
After that we are going to create our main Window class that extends from QDialog . and in the constructor of the class we need to initialize some requirements of the window . also we have called our initWindow() method in here.
|
1 2 3 4 5 6 7 8 9 10 |
class Window(QDialog): def __init__(self): super().__init__() self.title = "PyQt5 Labels" self.top = 200 self.left = 400 self.width = 400 self.height = 100 self.iconName = "icon.png" self.InitWindow() |
After that we are going to create our InitWindow() method. we set our window title, window icon and window geometry.
|
1 2 3 4 |
def InitWindow(self): self.setWindowIcon(QtGui.QIcon("icon.png")) self.setWindowTitle(self.title) self.setGeometry(self.left, self.top, self.width, self.height) |
In here we have created QVBoxLayout object with QLabel, and we have added the label to the layout. also we have set the font for the QLabel.
|
1 2 3 4 5 |
vbox = QVBoxLayout() label = QLabel("This Is PyQt5 Labels") vbox.addWidget(label) label2 = QLabel("This Is PyQt5 GUI Applicaition Development, Hello") label2.setFont(QtGui.QFont("Sanserif", 20)) |
This is used for giving color for our label.
|
1 |
label2.setStyleSheet('color:red') |
Also every PyQt5 application must create an application object.
|
1 |
app = QApplication(sys.argv) |
Finally, we enter the mainloop of the application. The event handling starts from this point.
|
1 2 |
window = Window() sys.exit(app.exec()) |
