[Qt-interest] Question regarding QTimer

[Tony Rietwyk]

Hi Vesa, 
 
A similar problem used to happen on Windows - but only when the mouse clicks
involved resizing or moving the window.

Subject: [Qt-interest] Question regarding QTimer


Hello all, 


I've simple question. I'm trying to start a timer when mouse press event is
received on eventfilter:


xxx::eventFilter(QObject *object, QEvent *event) 
{
    
    if ( event->type() == QEvent::MouseButtonPress )
    {
           m_timer->start(150); // msec
...


It seems that the timer timeouts always only after the mouse is released,
even if the mouse press is very long (many seconds). 
Is this known behavior and is there way to overcome the problem? Is the
system process blocking the application thread during the mouse press, so
even if the timeout should have happen much earlier, the slot is called only
after the mouse is released? 
Btw, my environment is Qt 4.7.2 on S^3 device. I've not tested the behavior
on other platforms. 




Thanks,
Vesa
