[SOLVED] QOpenGLFunctions moved to another class, shader subroutine stop working

glararan

Hi,

As topic say I moved QOpenGLFunction from class called MapView(QGLWidget) to class World(QObject).

I get same subroutine indexs, but when I'm calling:
@world->getGLFunctions()->glUniformSubroutinesuiv(GL_FRAGMENT_SHADER, 1, &eDisplaySubroutines[eDisplay]);@

Result in QGLWidget isn't, it using default Display subroutine in fragment shader, I'm not able to change it :(

Code before:
@// MapView constructor : eDisplaySubroutines(DisplayModeCount) /QVector/, eDisplay(TEXTURED) // index shadeTexturedAndLit, show correct
// QStringList
eDisplayNames << QStringLiteral("shadeSimpleWireFrame")
<< QStringLiteral("shadeTexturedAndLit")
<< QStringLiteral("shadeWorldTexturedWireframed")
<< QStringLiteral("shadeHidden");

// MapView initializeGL
this->makeCurrent();

GLfuncs = GLcontext->versionFunctions<QOpenGLFunctions_4_0_Core>();

if(!GLfuncs)
{
    qFatal("Requires OpenGL >= 4.0");
    exit(1);
}

GLfuncs->initializeOpenGLFunctions();
// ....
// Get subroutine indices
for(int i = 0; i < DisplayModeCount; ++i)
    eDisplaySubroutines[i] = GLfuncs->glGetSubroutineIndex(shader->programId(), GL_FRAGMENT_SHADER, eDisplayNames.at(i).toLatin1());

// MapView paintGL
this->makeCurrent();

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

material->bind();

QOpenGLShaderProgramPtr shader = material->shader();
shader->bind();

// Set the fragment shader display mode subroutine
GLfuncs->glUniformSubroutinesuiv(GL_FRAGMENT_SHADER, 1, &eDisplaySubroutines[eDisplay]);

Code after:
@// MapView constructor : eDisplaySubroutines(world->DisplayModeCount) /QVector/, eDisplay(world->TEXTURED) // eDiplay is moved to world!!! index shadeTexturedAndLit, btw show wireframe in frag its default
// QStringList
eDisplayNames << QStringLiteral("shadeSimpleWireFrame")
<< QStringLiteral("shadeTexturedAndLit")
<< QStringLiteral("shadeWorldTexturedWireframed")
<< QStringLiteral("shadeHidden");

// MapView initializeGL
this->makeCurrent();

// Initialize World
world->initialize(GLcontext);
// ....
// Get subroutine indices
for(int i = 0; i < world->DisplayModeCount; ++i)
    eDisplaySubroutines[i] = world->getGLFunctions()->glGetSubroutineIndex(shader->programId(), GL_FRAGMENT_SHADER, eDisplayNames.at(i).toLatin1());

// MapView paintGL
this->makeCurrent();

glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT);

world->material->bind();

QOpenGLShaderProgramPtr shader = world->material->shader();
shader->bind();

// Set the fragment shader display mode subroutine
world->getGLFunctions()->glUniformSubroutinesuiv(GL_FRAGMENT_SHADER, 1, &eDisplaySubroutines[world->displayMode()]);

// World initialize
void World::initialize(QOpenGLContext* context)
{
GLfuncs = context->versionFunctions<QOpenGLFunctions_4_0_Core>();

if(!GLfuncs)
{
    qFatal("Requires OpenGL >= 4.0");
    exit(1);
}

GLfuncs->initializeOpenGLFunctions();

// prepare Shaders
material = MaterialPtr(new Material);
material->setShaders(":/shaders/terraintessellation.vert",
                     ":/shaders/terraintessellation.tcs",
                     ":/shaders/terraintessellation.tes",
                     ":/shaders/terraintessellation.geom",
                     ":/shaders/terraintessellation.frag");

// ...
}

// World getGLFunctions()
QOpenGLFunctions_4_0_Core* getGLFunctions() { return GLfuncs; }
@

I don't see any trouble in code, but there must be. But what?

Thanks

SOLUTION: I needed that for MapTile class which was in array in World.. call it in MapTile body
