GUI
GUI Tkinter
GUI Tkinter
- Python offers multiple options for developing Graphical User Interface.
- tkinter is most commonly used library.
- Steps To create a standard GUI Application.
- Importing the module – tkinter
- Create the main window (container)
- Add widgets(controls) to the main window.
- Define Event handlers for the widgets.
- Start main loop
main window
- Main Window of python GUI application can be create by using class Tk.
winobj = Tk()
mainloop()
- This is the last statement of our GUI application.
- When the main loop is entered, the GUI takes over control from there.
- All other actions are handled via callbacks i.e event handlers.
- This method is of class Tk.
winobj.mainloop()
Class Tk
- This class is used to create our main window.
- We can directly create its object or we can derive a new class from it.
| Constructor: | |
|---|---|
| TK() | will create an empty window. |
| Methods: | |
|---|---|
| title(string) | Set the title of this window. |
| maxsize (width, height) | Set max WIDTH and HEIGHT for this widget. |
| minsize (width, height) | Set min WIDTH and HEIGHT for this widget. |
| resizable(width, height) |
|
| geometry("WidthxHeight") | Sets the size of window. |
| destroy( ) | Closes the window. |
| configure(**options) |
Sets the attributes of window. Options can be:
|
| cursor | Curosr for window : "arrow" ,"circle" , "clock" , "cross" , "plus" ,"watch" etc |
#WAP to create window of size 500x300 of red color with title CCIT.
from tkinter import *
win = Tk()
win.configure(background="red", cursor="cross")
win.geometry("500x300")
win.title("CCIT")
win.mainloop()
