Window / Questions about sf::Input
« on: January 02, 2011, 03:09:51 am »
Hi, I am wondering how does sf::Input work, does it works as how the tutorial said? which is have a boolean variable to store the key state/mouse button state? And this boolean variable will be flag accordingly to the Event?

I roughly understand the need for sf::Input for realtime inputs. However I don't really understand why the need for sf::Input::GetMouseX/Y. Wouldn't the mouse position from the event suffice for realtime input?

Since I assume that whether a person get the mouse position from the Event or from the sf::Input, wouldn't it be the same until the next mouse move sf::event is fired?

Window / mulitple sf::window and OpenGL
« on: December 31, 2010, 12:26:00 pm »
hi if i have multiple sf::Window, can they be on different threads? and if I am to call glBegin() glEnd() from a different thread will it work?

e,g
thread1 : sf::Window A
thread2 : sf::Window B
thread3 : sf::Window C
thread4 : glBegin()/glEnd() other opengl commands

is this allowed?? or mus all sf::Window(s) reside on the same thread along with all opengl commands?

Window / Can GetEvent or sf::Input be called from another thread?
« on: December 29, 2010, 10:34:10 am »
Hi I was wondering if sf::Window::GetEvent or sf::Input be used from another thread from that of which the window is created?

for example
thread 1: Create the Window and do all rendering (aka Graphics Thread)
thread 2: Physics Thread
thread 3: Main Loop where I call window::GetEvent or use the sf::Input here?

is this possible??

Window / SFML error checking and exceptions
« on: December 27, 2010, 12:11:50 pm »
Hi, do SFML throw exceptions in any of the classes? If not how should I check for failures? for example when creating the sf::Window class, how would I know if the constructor failed? or sf::Window::Create failed?

Window / Is there anyway to specify the bit size for each channel?

Hi I was wondering is there anyway to specify the channel size for each RGBA component when creating the window/opengl context?

General / Static linking giving warning and mem leak in debug
« on: December 20, 2010, 11:36:52 pm »
Hi, I created a project in VS2010 and in debug mode, I link to
sfml-system-s-d.lib
sfml-window-s-d.lib

Code: [Select]

int main(int argc, char* args[])
{
    DETECT_MEMORY_LEAK;

    try
    {
        sf::Window App;
    }
    catch (std::exception& err)
    {
        std::cout << err.what() << "\n";
    }

    std::cin.get();

    return 0;
}


however when i compile it gives a lot of warning:
Code: [Select]

1>sfml-system-s-d.lib(Platform.obj) : warning LNK4099: PDB 'vc100.pdb' was not found with 'sfml-system-s-d.lib(Platform.obj)' or at 'C:\ Framework\Debug\vc100.pdb'; linking object as if no debug info
1>sfml-system-s-d.lib(Clock.obj) : warning LNK4099: PDB 'vc100.pdb' was not found with 'sfml-system-s-d.lib(Clock.obj)' or at 'C:\Framework\Debug\vc100.pdb'; linking object as if no debug info


but it still run fines. I guess because it can't find the symbol to load for debugging?

However when I exit the program. The CRT is detecting a number of memory leaks. I am using the _CrtDumpMemoryLeaks() along with _CrtSetDbgFlag(), to check for memory leaks.
