Input user data into the textfield.

[nagesh.chetana]

I have drawn a textfield (i have not used FORM or TEXTFIELD option) everything is done by draw and fill rectangle.
Now i need to input, user data into the textfield.

If i had used the form, my problem would have been solved but according to the requirement everything should be drawn on the canvas.
Can anyone help me in this?
