\title Two-way Button Example
The Two-way button example shows how to use \l{The State Machine
Framework} to implement a simple state machine that toggles the current
state when a button is clicked.
\snippet examples/statemachine/twowaybutton/main.cpp 0
The application's main() function begins by constructing the application
object, a button and a state machine.
\snippet examples/statemachine/twowaybutton/main.cpp 1
The state machine has two states; \c on and \c off. When either state is
entered, the text of the button will be set accordingly.
\snippet examples/statemachine/twowaybutton/main.cpp 2
When the state machine is in the \c off state and the button is clicked,
it will transition to the \c on state; when the state machine is in the \c
on state and the button is clicked, it will transition to the \c off
state.
\snippet examples/statemachine/twowaybutton/main.cpp 3
The states are added to the state machine; they become top-level (sibling)
states.
\snippet examples/statemachine/twowaybutton/main.cpp 4
The initial state is \c off; this is the state the state machine will
immediately transition to once the state machine is started.
\snippet examples/statemachine/twowaybutton/main.cpp 5
Finally, the button is resized and made visible, and the application event
loop is entered.
