How to program a mouse event?

mouseEvent
Hi, I need to program pool.

Right now, I'd like to make a mouseEvent so that, when i click on the screen, i get the position of the mouse.
I know to use event->x(); to get the xCoordinate, but I don't know how to impletement the clickEvent itself.

I got:

void mouseMoveEvent(QMouseEvent* event)
{
if(event->button())
{
xPos = event->x();
yPos = event->y();
}
}
 
main
{
...
while(certain condition)
{
QMouseEvent *event;
while(!(event->button()))
{
event;
}
 
mouseMoveEvent(event);
...
}

void mouseMoveEvent(QMouseEvent* event)
{
if(event->button())
{
xPos = event->x();
yPos = event->y();
}
}

main
{
...
while(certain condition)
{
QMouseEvent *event;
while(!(event->button()))
{
event;
}

mouseMoveEvent(event);
...
}

To copy to clipboard, switch view to plain text mode 

If I do this, it gives a segmentation fault.

I got 0 experience with implementing a mouseclick, unfortunatly :/
