In this topic we'll be looking at is how to move an object in OpenGL using keyboard controls. Qt provides an easy way to detect keyboard events using virtual functions, namely keyPressEvent() and keyReleaseEvent(). We will be using the previous example and adding to it.
Open up
mainwindow.hand declare two floating point numbers calledmoveXandmoveZ:private: QOpenGLContext* context; QOpenGLFunctions* openGLFunctions; float rotation; GLuint texID[1]; float moveX; float moveZ;
After that, declare the
keyPressEvent()function, like so:public: explicit MainWindow(QWidget *parent = 0); ~MainWindow(); void keyPressEvent(QKeyEvent *event);Then, open up
mainwindow.cppand set the default values for the two variables we just declared:MainWindow::MainWindow(QWidget *parent) { setSurfaceType(QWindow::OpenGLSurface); QSurfaceFormat format; format.setProfile(QSurfaceFormat::CompatibilityProfile); format.setVersion(2...
