I have a simple UI with a button, after pressing the button I should open a new window where OpenGL stuff should be drawn. I'm trying to do this with QOpenGLWidget but the InitializeGL() and paintGL() functions are never called.
So basically I have my main with a function that should start everything:
void test::displayOpenGLObjects
{
newOpenGLContext = std::make_unique(this);
}
Visualization_OpenGL.cpp
test::Visualization_OpenGL(QWidget *parent): QOpenGLWidget(parent)
{
QOpenGLWidget *test_window = new QOpenGLWidget();
test_window->setWindowTitle("OpenGL Visualization");
test_window->makeCurrent();
test_window->show();
}
test::initializeGL(){
...
}
test::paintGL(){
...
}
test::resizeGL(){
...
}
And the header:
class Visualization_OpenGL : public QOpenGLWidget, public QOpenGLFunctions
{
Q_OBJECT
public:
Visualization_OpenGL(QWidget *parent);
~Visualization_OpenGL();
protected:
void initializeGL() override;
void resizeGL(int w, int h) override;
void paintGL() override;
};
The examples I've seen all draw everything on the mainwindow, and when I do it like that, the paintGL() and initializeGL() are indeed called, but I need to have a separate window for this, I'm guessing my problem is something involving the QOpenGLWidget *test_window = new QOpenGLWidget(); but I'm not sure how to fix. I'm super new with this so I'm sorry if this is a super noob question, but any help will be appreciated.
