  2. Python  වලට  ගොඩක් Frameworks තියෙනවා. ඒ වුනත්  Tkinter කියන්නෙ Python වල Standard Library වලට හදපු එකම Framework එක.

    Window එකක් Create කර ගන්න ඉස්සෙල්ලම ඔයාගේ  IDE එක හරි Text Editor එක හරි Open කරලා මේ Code එක Run කරලා බලන්න.
    import tkinter as tk
    window = tk.Tk()
    මේ Code එක Run  කරාට පස්සෙ පහළ තියෙනවා වගේ මොකක් හරි Empty Window එකක් එයි. මම මෙතන Window කියල හදල තියෙන්නේ Variable එකක්.

    Tkinter Windows

    මේ Window එකේ Appearance එක ඔයාගේ PC එකේ  OS එක මත Depend වෙනවා.

    ඔයා මේ Window එක Resize කර ගන්න ඕන නම් මේ Code එකත් ඔයාගේ කලින් Code එකට Add කර ගන්න. ඊට පස්සෙ Width එකටයි Height එකටයි එක එක Values දාල බලන්න. Bracket එක ඇතුලෙ Width එකයි Height එකයි පිළිවෙලට දාලා තියෙන්නේ. මේකට මම geometry() කියන function එක Use කරවනවා.

    import tkinter as tk
    window = tk.Tk()
    window.geometry("100x100")

    ඊට පස්සෙ සාමන්‍ය Text එකක් මේ Window එකේ පෙන්වන්නේ මෙහෙමයි. මම මේකට Label කියන Widget එක Use කරනවා. මම ඒක new කියන Variable එකට Assign කරනවා. හැබැයි තාම මේක Window එකට Add කරලා නෑ.
    import tkinter as tk
    window = tk.Tk()
    window.geometry("100x100")
    new = tk.Label(text="Hello World")

    මේක Window එකට Add කරන්න .pack() කියන Method එක මම මෙතනදී Use කරනවා.

    import tkinter as tk
    window = tk.Tk()
    window.geometry("100x100")
    new = tk.Label(text="Hello World")
    new.pack()

    මෙතනදී මම කියල දුන්නේ Python GUI(Graphical User Interface) එකට පොඩි Introduction එකක්. ඔයා තව GUI ගැන ඉගෙන ගන්න පුලුවන් Sources Mention කරන්න කියල තිබුණා. මේ Tutorial එක ඔයාට Useful වෙයි කියල හිතනවා. ඉස්සරහට ගොඩක් වෙලාවට පසිඳු අයියත්  SL Geek School Channel එකේ GUI ගැන Tutorials කරයි.

    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 http://wxpython.org.
    • JPython − JPython is a Python port for Java which gives Python scripts seamless access to Java class libraries on the local machine http://www.jython.org.

    There are many other interfaces available, which you can find them on the net.

    Tkinter Programming

    Tkinter 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/python

import Tkinter
top = Tkinter.Tk()
# Code to add widgets will go here...
top.mainloop()

    This would create a following window −

    TK Window

    Tkinter Widgets

    Tkinter 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 & Description
    1 ButtonThe Button widget is used to display buttons in your application.
    2 CanvasThe Canvas widget is used to draw shapes, such as lines, ovals, polygons and rectangles, in your application.
    3 CheckbuttonThe Checkbutton widget is used to display a number of options as checkboxes. The user can select multiple options at a time.
    4 EntryThe Entry widget is used to display a single-line text field for accepting values from a user.
    5 FrameThe Frame widget is used as a container widget to organize other widgets.
    6 LabelThe Label widget is used to provide a single-line caption for other widgets. It can also contain images.
    7 ListboxThe Listbox widget is used to provide a list of options to a user.
    8 MenubuttonThe Menubutton widget is used to display menus in your application.
    9 MenuThe Menu widget is used to provide various commands to a user. These commands are contained inside Menubutton.
    10 MessageThe Message widget is used to display multiline text fields for accepting values from a user.
    11 RadiobuttonThe Radiobutton widget is used to display a number of options as radio buttons. The user can select only one option at a time.
    12 ScaleThe Scale widget is used to provide a slider widget.
    13 ScrollbarThe Scrollbar widget is used to add scrolling capability to various widgets, such as list boxes.
    14 TextThe Text widget is used to display text in multiple lines.
    15 ToplevelThe Toplevel widget is used to provide a separate window container.
    16 SpinboxThe Spinbox widget is a variant of the standard Tkinter Entry widget, which can be used to select from a fixed number of values.
    17 PanedWindowA PanedWindow is a container widget that may contain any number of panes, arranged horizontally or vertically.
    18 LabelFrameA labelframe is a simple container widget. Its primary purpose is to act as a spacer or container for complex window layouts.
    19 tkMessageBoxThis module is used to display message boxes in your applications.

    Let us study these widgets in detail −

    Standard attributes

    Let us take a look at how some of their common attributes.such as sizes, colors and fonts are specified.

    Let us study them briefly −

    Geometry Management

    All Tkinter widgets have access to specific geometry management methods, which have the purpose of organizing widgets throughout the parent widget area. Tkinter exposes the following geometry manager classes: pack, grid, and place.

    • The pack() Method − This geometry manager organizes widgets in blocks before placing them in the parent widget.
    • The grid() Method − This geometry manager organizes widgets in a table-like structure in the parent widget.
    • The place() Method − This geometry manager organizes widgets by placing them in a specific position in the parent widget.

    Let us study the geometry management methods briefly −
