QT4 Widgets

We have various widgets that we can access with PyQT. Including:

Textbox
Combobox
Calendar

For more widgets we suggest using the GUI creation tool covered in the next tutorial.

Textbox widget Input fields are present in nearly every application. In PyQT4 an input field can be created using the QLineEdit() function.

#! /usr/bin/env python
# -*- coding: utf-8 -*-
#
import sys
from PyQt4.QtGui import *
# Create an PyQT4 application object.
a = QApplication(sys.argv)
# The QWidget widget is the base class of all user interface objects in PyQt4.
w = QMainWindow()
# Set window size.
w.resize(320, 100)
# Set window title
w.setWindowTitle("PyQT Python Widget!")
# Create textbox
textbox = QLineEdit(w)
textbox.move(20, 20)
textbox.resize(280,40)
# Show window
w.show()
sys.exit(a.exec_())

Combobox A combobox can be used to select an item from a list.

#! /usr/bin/env python
# -*- coding: utf-8 -*-
#
import sys
from PyQt4.QtGui import *
# Create an PyQT4 application object.
a = QApplication(sys.argv)
# The QWidget widget is the base class of all user interface objects in PyQt4.
w = QMainWindow()
# Set window size.
w.resize(320, 100)
# Set window title
w.setWindowTitle("PyQT Python Widget!")
# Create combobox
combo = QComboBox(w)
combo.addItem("Python")
combo.addItem("Perl")
combo.addItem("Java")
combo.addItem("C++")
combo.move(20,20)
# Show window
w.show()
sys.exit(a.exec_())

Calendar widget The PyQT4 library has a calendar widget, you can create it using the QCalendarWidget() call.

#! /usr/bin/env python
# -*- coding: utf-8 -*-
#
import sys
from PyQt4.QtGui import *
# Create an PyQT4 application object.
a = QApplication(sys.argv)
# The QWidget widget is the base class of all user interface objects in PyQt4.
w = QMainWindow()
# Set window size.
w.resize(320, 240)
# Set window title
w.setWindowTitle("PyQT Python Widget!")
# Create calendar
cal = QCalendarWidget(w)
cal.setGridVisible(True)
cal.move(0, 0)
cal.resize(320,240)
# Show window
w.show()
sys.exit(a.exec_())

Result:
