GUI TKINTER

Bind Method

Tkinter provides a mechanism to let the programmer deal with events.
For each widget, it's possible to bind Python functions and methods to an event.
If the defined event occurs in the widget, the "handler" function is called with an event object.

Syntax:

widget.bind(event, handler)

Notes NOTE: - This Event Object contains information about the event. Such as mouse co-ordinates, key etc

Component Events

Methods:
<Enter>	The mouse pointer entered the widget.
<Leave>	The mouse pointer left the widget.
<FocusIn>	Keyboard focus was moved to this widget.
<FocusOut>	Keyboard focus was moved from this widget.

#Example

from tkinter import *
class MyFrame(Tk):
  def __init__(self):
    super().__init__()
    self.geometry("500x300")
    self.configure(bg="white")
    self.lbl=Label(self,text="CCIT",font="Arial 100 bold",bg="white")
    self.lbl.pack(padx=50,pady=50)
    self.lbl.bind("",self.OnEnter)
    self.lbl.bind("",self.OnLeave)
  def OnEnter(self,e):
    self.lbl.config(fg="red")
  def OnLeave(self,e):
    self.lbl.config(fg="black")
frm=MyFrame()
frm.mainloop()
