+- ### Now on the main window of the application, one START button will be there clicking on which the main window of virtual keyboard opens.
+- ### In this window there is a text area given, and a button KEYBOARD, clicking on which a virtual keyboard will pop up in the same frame.
+- ### using this virtual keyboard user can enter any text, character, any special charater, digits, and some emoji's also. 
+- ### Inside Keyboard also there is a clear, backspace, sace, tab button also.
+- ### Also there is one hide button, clicking on which the virtual keyboard disappears.
+- ### After user has entered some text in textarea using virtual keyboard, then clicking on the PRINT button, shows messagebox, showing what is printed.
