guys i have a scenario in which i send signal every certain amount of time delay.
Qt Code: 
  1. QTimer *timer = new QTimer(this);
  2. 	     connect(timer, SIGNAL(timeout()), this, SLOT(drawDemo()));
  3. 	     timer->start(30);
To copy to clipboard, switch view to plain text mode 

i receive this signal on a slot which do a hards drawing.sometimes when the slot takes very long time more than the period of the signal delay time

Qt Code: 
  1. void drawDemo()
  2. {
  3.   //heavy drawing
  4. }
To copy to clipboard, switch view to plain text mode 

my question is what happens when the time comes of the signal ??
i mean does the qt sense the signal ? o it will be busy finish the slot?
and wait will happen if it will handle the signal while the slot is doing ?
do the qt has a queue for lost signals ? or it just discard ?or what happens exactly in that scenario ?
