Window / [OSX] Window.getPosition return wrong coords

« on: November 16, 2012, 05:42:47 am »

In OSX, Window.getPosition() always return the coord (0, 900) despite manually setting or moving the window.

Here is a code example

#include <SFML/Window.hpp>
#include <SFML/OpenGL.hpp>
#include <iostream>

int main(int argc, char** argv)
{
    sf::ContextSettings context_settings(16, 0, 0, 3, 1);

    sf::Window window(sf::VideoMode(1024, 768),
        "SFML - OpenGL Test", sf::Style::Default, context_settings);

    window.setPosition(sf::Vector2i(50, 50));

    glClearColor(0.39f, 0.58f, 0.93f, 1.0f);

    bool running = true;

    while (running)
    {
        sf::Event event;

        while (window.pollEvent(event))
        {
            if (event.type == sf::Event::Closed)
            {
                running = false;
            }
            else if (event.type == sf::Event::Resized)
            {
                glViewport(0, 0, event.size.width, event.size.height);
            }
            else if (event.type == sf::Event::KeyPressed)
            {
                if (event.key.code == sf::Keyboard::A)
                {
                    printf("Window Position - %i, %i\n",
                        window.getPosition().x, window.getPosition().y);
                }
            }
        }

        glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

        window.display();
    }

    return EXIT_SUCCESS;
}
 

Pressing the key 'A' always prints the following output:

Window Position - 0, 900
Window Position - 0, 900
 

I am using the build from the source repository.

P.S another side question. I notice that setPosition takes a signed integer. Does it means it can accept negative coords. If it does, how does the negative coord affect window placement? In OSX, if i do setPosition({-50, -50}) the window wrap to the bottom right instead of the top left.

General / [OSX] sfml 2.0 RC and opengl 3.2

« on: November 09, 2012, 08:56:12 am »

Following this thread

http://en.sfml-dev.org/forums/index.php?topic=9083.msg61236#msg61236

and after adding the following code to SFContext.mm to the function SFContext::createContext

// Add support for OpenGL 3.2 on Mac OS X Lion and later
    if (settings.majorVersion > 3 || (settings.majorVersion == 3 && settings.minorVersion >= 2)) {
        attrs.push_back(NSOpenGLPFAOpenGLProfile);
        attrs.push_back(NSOpenGLProfileVersion3_2Core);
    } else {
        attrs.push_back(NSOpenGLPFAOpenGLProfile);
        attrs.push_back(NSOpenGLProfileVersionLegacy);
    }

 

It gives the following error upon attempting to create a opengl 3.2 context

2012-11-09 15:42:08.715 sfml-test-d[8498:5503] invalid share context
2012-11-09 15:42:08.717 sfml-test-d[8498:5503] invalid context
Error. Unable to create the context.

My mac does support opengl 3.2 core profile.

Graphics / [OS X] Lion and opengl 3

« on: October 29, 2011, 12:18:22 pm »

Hi, just wanted to ask any mac user out there if Lion officially support opengl 3 contexts?

I heard rumors on the web that Lion have supports up till 3.2 contexts.

However I can't seems to create SFML using a 3.[0|1|2] context. It always defaults to a 2.1 context

My hardware does support opengl 3.3 as I have created a 3.3 context in windows using boot camp

Window / When is the global shared context created??

« on: May 13, 2011, 08:53:27 am »

Hi, does sfml creates a global context for sharing. When is this global context created? Is it created when a sf::Window is created?

e.g

Code: [Select]


On first create of sf::Window
    create shared global context
    create render context and share with the global context

Window / sf::RenderWindow opengl version vs glGetString(GL_VERSION)

« on: May 04, 2011, 07:44:13 pm »

hi, in sfml2 on windows, is anyone getting a different version from glGetString(GL_VERSION) versus the one reported back by sf::ContextSettings?

I created a RenderWindow with 2.0 context, but glGetString always report back as version 3.3

I was wondering if this happens only on my machine or is it happening to others too?

Window / [SFML2][OSX] Create another window after closing the first

Hi, in OSX for sfml2, how do i create a window, close it, and recreate it again??

I did something like:

Code: [Select]

        // It's useless here because active window is always the same,

        //App.SetActive(true);

        // Clear color and depth buffer

        // Finally, display rendered frame on screen
        App.Display();

        //App.SetActive(false);
    }
}

int main()
{
WindowFunction();

WindowFunction();

return EXIT_SUCCESS;
}


if i press 'esc' to close the first window, it aborts with a seg fault. If I press the 'cross' button at the top left corner of the first window, it aborts with a pure virtual function call error.

Window / [SFML 2] Set window focus

« on: March 13, 2011, 05:24:22 am »

hi, is there any way to set the window focus? After creating my window, the window is always not in focus (e.g it doesn't capture key press event), and I have to click on it to set it as the focus.

Window / sf::ContextSettings, opengl version hint

« on: January 29, 2011, 04:27:54 pm »

hi, I have a nvidia 8600 which can support opengl 3.3, however no matter what value i put as the value for the major, minor parameters in ContextSettings, it always create a opengl2.0 context instead.

Is there something I am missing out?

Window / SFML2 SetActive() Failed to activate window context

« on: January 18, 2011, 12:27:59 pm »

Hi, I create a simple app and in the main loop when i do

App.SetActive(true);

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

App.Display();

App.SetActive(false);

When running, it output on the console "Failed to activate window context". If I comment away App.SetActive(false); everything is normal.

Why is it that calling App.SetActive(false) would produce that error? Is there a change in the proper usage of SetActive() in SFML2.0?

P.S: this problem did not appear in SFML1.6

regards.

General discussions / SFML 2.0 cmake installation and VS2010

« on: January 18, 2011, 10:44:57 am »

the code and source compiles fine. However I am having problem with the installation step which moves the files to a specified location as stated in the CMAKE_INSTALL_PREFIX.

after running cmake the VS2010 sln will include a project call "INSTALL" which I assume would install the files to the proper location. However when I compile the project "INSTALL" it gave an error saying "can't find the batch label specified - VCReportError"

Is there something I am missing out?

Window / SetPosition and mutex. Anyway inbuilt way to avoid?

« on: January 15, 2011, 06:40:50 am »

Hi, is there anyway inbuilt thread safe flag in sfml which I can specify to allow calls to be thread safe? or do I have to manually wrap every sfml call with a mutex.

for e.g sf::Window::SetPosition which can be access from multiple thread.

Must I have a mutex for every SetPosition call?
