the program: + +* Create a window. + +.. code-block:: cpp + + /// Create a window + viz::Viz3d myWindow("Viz Demo"); + +* Start event loop. This event loop will run until user terminates it by pressing **e**, **E**, **q**, **Q**. + +.. code-block:: cpp + + /// Start event loop + myWindow.spin(); + +* Access same window via its name. Since windows are implicitly shared, **sameWindow** is exactly the same with **myWindow**. If the name does not exist, a new window is created. + +.. code-block:: cpp + + /// Access window via its name + viz::Viz3d sameWindow = viz::get("Viz Demo"); + +* Start a controlled event loop. Once it starts, **wasStopped** is set to false. Inside the while loop, in each iteration, **spinOnce** is called to prevent event loop from completely stopping. Inside the while loop, user can execute other statements including those which interact with the window. + +.. code-block:: cpp + + /// Event loop is over when pressed q, Q, e, E + /// Start event loop once for 1 millisecond + sameWindow.spinOnce(1, true); + while(!sameWindow.wasStopped()) + { + /// Interact with window + + /// Event loop for 1 millisecond + sameWindow.spinOnce(1, true); + } +
