Widgets in a layout

This page contains the source code shown in the Creating widgets and a layout video on YouTube.

This shows basic widget creation, though most programs will tend to create and instantiate subclasses of QWidget or other widget classes for their main user interfaces.

   1 # [Create a window]
   2 
   3 import sys
   4 from PyQt4.QtGui import *
   5 
   6 app = QApplication(sys.argv) #ignore()
   7 window = QWidget()
   8 window.setWindowTitle("Hello World")
   9 window.show()
  10 
  11 # [Add widgets to the widget]
  12 
  13 # Create some widgets (these won't appear immediately):
  14 nameLabel = QLabel("Name:")
  15 nameEdit = QLineEdit()
  16 addressLabel = QLabel("Address:")
  17 addressEdit = QTextEdit()
  18 
  19 # Put the widgets in a layout (now they start to appear):
  20 layout = QGridLayout(window)
  21 layout.addWidget(nameLabel, 0, 0)
  22 layout.addWidget(nameEdit, 0, 1)
  23 layout.addWidget(addressLabel, 1, 0)
  24 layout.addWidget(addressEdit, 1, 1)
  25 layout.setRowStretch(2, 1)
  26 
  27 # [Resizing the window]
  28 
  29 # Let's resize the window:
  30 window.resize(480, 160)
  31 
  32 # The widgets are managed by the layout...
  33 window.resize(320, 180)
  34 
  35 # [Run the application]
  36 
  37 # Start the event loop...
  38 sys.exit(app.exec_())
