| \title Two-way Button Example |
| |
| \brief 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 statemachine/twowaybutton/main.cpp 0 |
| |
| The application's main() function begins by constructing the application |
| object, a button and a state machine. |
| |
| \snippet 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 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 statemachine/twowaybutton/main.cpp 3 |
| |
| The states are added to the state machine; they become top-level (sibling) |
| states. |
| |
| \snippet 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 statemachine/twowaybutton/main.cpp 5 |
| |
| Finally, the button is resized and made visible, and the application event |
| loop is entered. |
