Pause functionality in Qt using QTimer on button press
-
0 down vote favorite
I am trying to implement pause button for a game I am developing in Qt + OpenGL.
I want to implement it using QTimer. Basically I am updating screen per 100ms. So in order to pause game, I will stop the timer on button press. and when button is again pressed i will start the timer again
Here is my pauseOrPlay SLOT:
@
void Window::pauseOrPlay()
{
GLWidget::modifyTimer = TRUE;
GLWidget::isPaused = !GLWidget::isPaused;GLWidget timerUpdater;
timerUpdater.timerFunc();
}
@and Here is my timerFunc()
@
GLvoid GLWidget::timerFunc()
{
static QTimer *timer = new QTimer(this);
connect(timer, SIGNAL(timeout()), this, SLOT(update()));if( GLWidget::isPaused)
timer->start(100);
else
timer->stop();}
@But I am not getting the functionality. I get paused screen on this particular code and upon trying few tweaks here and there, sometimes I get screen updating very fastly which pointed me to this but I was unable to find cure to my problem somehow
This maybe bit naive question about Qt, so may be I am missing something very basic. Any help or Pointers??

yes, and due to this my @QTimer *timer@ was getting created everytime,
So what I did was:
made @QTimer *timer@ member of my class. on buttonpressed called a member function of my class and in that function did timer stop or start.Thanks for the help though
