sf::Keyboard::isKeyPressed only when window is active?

[bobingabout]

As anyone who needs to use the keyboard will know, there are 2 methods for grabbing keyboard input in SFML.

Code: [Select]

if(sf::Keyboard::isKeyPressed(sf::Keyboard::A))and

Code: [Select]

if((Event.type == sf::Event::KeyPressed) && (Event.key.code == sf::Keyboard::A))
The first of which is true whenever the A key is held down, and ALWAYS when the A key is held down, wether the window is active or not.

The second, is a more classic "Key pressed" function, and returns true the moment A is initially pressed (and repeats if held due to OS key auto-repeat when held funtion), but since this is checked against an event returned by sf::Window::pollEvent(sf::Event) is only true if the window is currently active when the key is pressed.

I had a look at the sf::Window class to see if there was a function return to check if the window was currently active or not, but couldn't see anything...

Does anyone have a solution (Looking for something to add to the if() statement here) to make my first if check true ONLY when the window is currently active?

I was looking to do something along the lines of

Code: [Select]

if(window.isActive() && sf::Keyboard::isKeyPressed(sf::Keyboard::A))but as mentioned, the aparant lack of an isActive() function on sf::Window makes that difficult.

Handle window got/lost focus events and set a boolean flag accordingly if the window has focus.

Code: [Select]

if(Event.type == sf::Event::GainedFocus) focus = true;and

Code: [Select]

if(Event.type == sf::Event::LostFocus) focus = false;?

Yes

Thankyou, trying that now, it seems to do the job.

I do what zsbzsb mentioned - keeping track of focus events with a boolean; it works well enough. However, applications occasionally start without focus so it needs to lose it and regain it for your boolean to be correct. I believe there is a ticket for this fix on SFML.

You didn't mention which operating system you are using but there is a temporary solution for Windows. You'll need to #include <Windows.h> and use this line:

SetForegroundWindow(window.getSystemHandle());

after creating the window with SFML. window is the window that was created.
This should also send a sf::Event::GainedFocus event to the application.
