Mouse Events

[Atomic_Sheep]

Hi guys, have a nooby question on mouse events.

When you create a window into which you'll put a widget that will then track mouse clicks etc, why are we creating:

void GLWidget::mousePressEvent(QMouseEvent *event)
 {
     lastPos = event->pos();
 }

void GLWidget::mousePressEvent(QMouseEvent *event)
 {
     lastPos = event->pos();
 }

To copy to clipboard, switch view to plain text mode 

Inside the Widget and not inside the window that is the container for our widget? I don't know why, but to me it seems more logical that the window is what will track the mouse location and mouse events rather than a widget created inside the window.
