Tkinter GUI Framework- Most Used Graphical User Interface

Programming Languages

“Tkinter-Most used GUI framework in Python”.

Python provided many options for developing the GUI. And all of GUI methods, Tkinter is the most common method uses in Python. This is a standard Python interface. Python with Tkinter GUI outputs the fast and simple way to develop the GUI application. It is developing a GUI using Tkinter is a simple task.

Let’s have a brief about Tkinter GUI-

What is Tkinter?

Tkinter provides a basic concept of Python. Tkinter GUI framework is built for beginners and professionals. Python provides a standard library Tkinter for developing the GUI for desktop-based applications. And developing a desktop-based application with Tkinter GUI is not a difficult task. It is an easy task for developing Python GUI Tkinter applications. Tkinter is developing a top-level window that can be made by using the following task.

  • import Tkinter module.
  • Develop the main application window.
  • Add the widgets as labels, buttons, frames, etc. To a window.
  • Call the main event loop so it is the actions it can take location on the user’s computer screen.
from Tkinter import *

#develop the main window

top = Tk()

#Enter the main loop event

top.mainloop()

Tkinter Geometry

This is a python module that uses to develop GUI. This comes with Python So do not have to install but we can use pip command. Tkinter GUI framework provides different methods and one of them is the geometry() method. It uses to set off the dimensions of the Tkinter window also this uses to set portions of the window on the desktop.

Tkinter GUI frameworks geometry specifies the method by using that widgets are represented on display. And it gives the following methods.

  1.  A pack() method
  2. A grid() method
  3. A place() method

So let’s discuss these methods.

Tkinter Pack() Method

The pack() widget is used to organize in the block. And the positions widgets added to the python application using the pack() method can be handled by using the different choices specified in the methods cell. And the syntax uses the pack() given below.

widget.pack(options)

A-List of possible choices it can be passed in the pack() is given below.

ExpandIf this is set to true, the widget expands to fill any space.
FillBy default, the fill is set to NONE. However, we can set it to X and Y to determine whether the widgets contain any extra space.
SizeThis represents the side of the parent to which the widget is to be located at the window.

Tkinter Grid() Method

Its geometry manager organizes widgets in a table-like structure in the Janak widget. Se here is a syntax given below.

widget.grid( grid_options )

ColumnIt is represented by Zero. The column number in which the widget is to be located.
Column-spanIt is the width of the widget. This represents the number of columns up to which, the column is expanded.
Ipadx, IpadyThis represents a number of pixels to pad the widget inside the widget’s border.
Padx, PadyThis represents a number of pixels to pad the widget outside the widget’s border.
RowThe row number in which the widget is to be placed. The topmost row is represented by 0.
Row SpanThe height of the widget the number of the row up to which the widget is expanded.
StickyIf the cell is more than a widget, then sticky is used to specify the stand of the widget inside the cell. That may be the concatenation of the sticky letters representing the stand of the widget. This may be N, E, W, S, NE, NW, NS, EW, ES.

Tkinter Grid() Method

Tkinter place() method

The place() geometry manager organizations the widgets to the specific X and Y coordinates. The syntax is given below.

widget.place(options)

AnchorThe anchor represents the exact position of the widget inside the container. And the default value is NW upper left corner.
Border ModeIt is the default value of the border and type is WITHIN which refers to ignore the parent’s inside the border. The other choice is OUTSIDE.
Height, WidthThis is referred to as the height and width in pixels.
Relheight, RelwidthThis is represented as the float between 0.0 and 1.0 indicating the fraction of the parent’s height and width.
Relx, RelyThis is represented as the float between 0.0 and 1.0 this is the offset in the horizontal and vertical way.
X, Ythat refers to horizontal and vertical offset in the pixels.
