import direct.directbase.DirectStart
from direct.gui.OnscreenText import OnscreenText 
from direct.gui.DirectGui import *
from pandac.PandaModules import *
 
#add some text
bk_text = "This is my Demo"
textObject = OnscreenText(text = bk_text, pos = (0.95,-0.95), 
scale = 0.07,fg=(1,0.5,0.5,1),align=TextNode.ACenter,mayChange=1)
 
#callback function to set  text 
def setText(textEntered):
	textObject.setText(textEntered)
 
#clear the text
def clearText():
	b.enterText('')
 
#add button
b = DirectEntry(text = "" ,scale=.05,command=setText,
