# Example 2 - Using fl in python with callbacks.
|
|
#
|
|
# The form is named 'main_form' and resides on file 'test_cb.fd'.
|
|
# It has three objects named button1, button2 and exitbutton.
|
|
# All buttons have callbacks with the same names as their corresponding
|
|
# buttons but with CB appended.

|
# main_form, button1, button2 and exitbutton.
