Detailed Description

This class handles the user inputs to perform rotations, translations and zoom. It derives from QGLWidget, the Qt class allowing OpenGL operations

Public Slots

• void setXRotation (double degrees)
• void setYRotation (double degrees)
• void setZRotation (double degrees)
• void setScale (double s)
• void setXTrans (double x)
• void setYTrans (double y)
• void setZTrans (double z)
• virtual void setRotationImpulse (double x, double y, double z)
• virtual void setTranslationImpulse (double x, double y, double z)

Public Member Functions

• GLControlWidget (QWidget *parent, QGLWidget *share=0)
• virtual void transform ()

Protected Slots

• virtual void animate ()

Protected Member Functions

• void setAnimationDelay (int ms)
• void mousePressEvent (QMouseEvent *e)
• void mouseReleaseEvent (QMouseEvent *e)
• void mouseMoveEvent (QMouseEvent *)
• void mouseDoubleClickEvent (QMouseEvent *)
• void wheelEvent (QWheelEvent *)
• void keyPressEvent (QKeyEvent *k)
• void showEvent (QShowEvent *)
