Python provides various options for developing graphical user interfaces (GUIs). Most important are listed below.Tkinter − Tkinter is the Python interface to the Tk GUI toolkit shipped with Python. We would look this option in this chapter.wxPython − This is an open-source Python interface for wxWindows.JPython − JPython is a Python port for Java which gives Python scripts seamless access to Java class libraries on the local machine.There are many other interfaces available, which you can find them on the net.
Tkinter ProgrammingTkinter is the standard GUI library for Python. Python when combined with Tkinter provides a fast and easy way to create GUI applications. Tkinter provides a powerful object-oriented interface to the Tk GUI toolkit.Creating a GUI application using Tkinter is an easy task. All you need to do is perform the following steps −.Import the Tkinter module.Create the GUI application main window.Add one or more of the above-mentioned widgets to the GUI application.Enter the main event loop to take action against each event triggered by the user.Example#!/usr/bin/pythonimport Tkintertop = Tkinter.Tk# Code to add widgets will go here.top.mainloopThis would create a following window − Tkinter WidgetsTkinter provides various controls, such as buttons, labels and text boxes used in a GUI application. These controls are commonly called widgets.There are currently 15 types of widgets in Tkinter. We present these widgets as well as a brief description in the following table − Sr.No.Operator & Description1The Button widget is used to display buttons in your application.2The Canvas widget is used to draw shapes, such as lines, ovals, polygons and rectangles, in your application.3The Checkbutton widget is used to display a number of options as checkboxes.
The user can select multiple options at a time.4The Entry widget is used to display a single-line text field for accepting values from a user.5The Frame widget is used as a container widget to organize other widgets.6The Label widget is used to provide a single-line caption for other widgets. It can also contain images.7The Listbox widget is used to provide a list of options to a user.8The Menubutton widget is used to display menus in your application.9The Menu widget is used to provide various commands to a user. These commands are contained inside Menubutton.10The Message widget is used to display multiline text fields for accepting values from a user.11The Radiobutton widget is used to display a number of options as radio buttons.
There are various GUI toolkits usable from Python.Very productive are true GUI-builders, where the programmer can arrange the GUI window and other components such as database by using the mouse only in an intuitive fashion like in Windows Delphi 2.0. Very little typing is required. For python, only Boa Constructor follows this paradigm. WXglade and Qt-designer, monkey studio etc. Come somewhat near but remain incomplete.Disadvantages with the following kits described below are:. Difficult deployment - the apps won't run on a particular GNU-Linux installation without major additional work.
breakage - apps won't work due to bit-rot. From Tkinter import. root = Tk frame = Frame ( root ) frame. Pack label = Label ( frame, text = 'Hey there.' Pack quitButton = Button ( frame, text = 'Quit', command = frame. Free download for nokia 6630. Quit ) quitButton. Pack root.

The bare GTK+ toolkit runs on Linux, Windows, and Mac OS X (port in progress), but the more extensive features — when combined with PyORBit and gnome-python — require a install, and can be used to write full featured GNOME applications.PyQt PyQt is a wrapper around the cross-platform. It has many supporting SQL, OpenGL, SVG, XML, and advanced graphics capabilities.A PyQt hello world example. From PyQt4.QtCore import.

It is very simple to learn and allows for compact user interfaces.The 'Hello World' example in pyFltk looks like. From fltk import. window = FlWindow ( 100, 100, 200, 90 ) button = FlButton ( 9, 20, 180, 50 ) button. Label ( 'Hello World' ) window. End window.
