Key pressed in QWidget::mousePressedEvent()

M Wong

Is there any way that let me know if the spacebar is being pressed inside QWidget::mousePressEvent() / QWidget::mouseMoveEvent() ?

You may try this

void Widget::mousePressEvent(QMouseEvent *e)
{
        if(e->button()==Qt::Key_Space) {
         e->accept();
    }
}

Thanks for your reply.
However I don't think your code will tell whether the SpaceBar is being pressed or not inside the mousePressEvent()...

Anyway, I now use Win32 API -- GetKeyState() / GetAsyncKeyState() to solve the problem.

Not to my knowledge, no. But you can intercept the key-press event as well as the mouse event and set a state internally that the spacebar is pressed.

That's possible, but the implications would be you code will be working only(!) on windows and you would require the windows SDKs to build it.

Kind regards.

Good Advice. I may try it... But I should stop programming now and get back to my real hobby -- 3DCG. ( Programming isn't even my hobby, I just need some app that's tailor-made for myself.
