Using Mouseevent together with Keypressedevents with OPENGL&QT

[uauaua]

Hello,

has anybody an idea how can use the "Mousemove event" together with an "Keypress event" for example "Z"-key to change the viewport settings.

I am using the following example (glwidget.cpp Example File):
@
void GLWidget::resizeGL(int width, int height) {
int side = qMin(width, height);
glViewport((width - side) / 2, (height - side) / 2, side, side);

 glMatrixMode(GL_PROJECTION);
 glLoadIdentity();
 glFrustum(-1.0, +1.0, -1.0, 1.0, near, far);
 glMatrixMode(GL_MODELVIEW);
 glLoadIdentity();
 glTranslated(0.0, 0.0, -40.0);

}@

The aim of this (for me frustating) game is to change the to variable "far" and or "near" in an similar mode like in CAD-Systems. a mouse move together with a pressed key.

Thank you for your help
