In-Depth Information
Take a look at this example where a string is assembled out of characters using the
Tex-
tEntered
event and, when the
Enter
(or
Return
) button is pressed, the text is set as the
title:
Note that the string buffer that we are using is of type
sf::String
and not
std::string
. The
sf::String
class is created to automatically handle conversion
between string types and encodings. As such, we do not have to worry about the language
or symbols on a keyboard layout—it can store any character from any language.
To finish off event handling, it is important to mention that there is an alternative to how
events are pulled from the window. Apart from using
Window::pollEvent()
, we can
also use
bool Window::waitEvent(Event& event)
, which blocks the thread
until an event is received. It only returns
false
when something wrong occurs inside (an
error or exception of some sort), otherwise it always returns
true
. This can be useful
