/* SFML::Event holds all the informations about a system event that just happened.
|
|
*
|
|
* Events are retrieved using the SFML::Window#GetEvent function.
|
|
*
|
|
* A SFML::Event instance contains the type of the event (mouse moved, key pressed, window closed, ...)
|
|
* as well as the details about this particular event. Please note that the event parameters are
|
|
* defined in a union, which means that only the member matching the type of the event will be properly
|
|
* filled; all other members will have undefined values and must not be read if the type of the event
|
|
* doesn't match. For example, if you received a KeyPressed event, then you must read the event.Key
|
|
* member, all other members such as event.MouseMove or event.Text will have undefined values.
|
|
*
|
|
* The ruby version differs from C++ in that the parameters are still stored in a union but that
|
|
* the values can be directly accessed from the event object. If you try to access any data which
|
|
* would be considered undefined then SFML::SomeKindOfException will be thrown.
|
|
*
|
|
* Usage example:
|
|
*
|
|
* while event = window.getEvent()
|
|
*
|
|
* # Request for closing the window
|
|
* if event.type == SFML::Event::Closed
|
|
* window.close
|
|
*
|
|
* # The escape key was pressed
|
|
* if ( event.type == sf::Event::KeyPressed ) && ( event.code == SFML::Key::Escape )
|
|
* window.close
|
|
*
|
|
* # The window was resized
|
|
* if event.type == SFML::Event::Resized
|
|
* DoSomethingWithTheNewSize(event.size);
|
|
*
|
|
* # etc ...
