# This example demonstrates the use of the TextInput functionality.
# One can tab through, or click into the text fields and change it's contents.

# accessed via TextInput#text.

# The TextInput object also maintains the position of the caret as the index
# of the character that it's left to via the caret_pos attribute. Furthermore,
