QTimer and QTimeLine

[martisho]

Hello high_flyer,

i have tryed what you said, but it doesn´t work, it happens the same, if i press the stop button quickly the function calls save dialog, if i cancel the save dialog, quickly, another save dialog is shown, the stopall is called several times.

I delete QTimer and QTimeLine, in the stopall function, but as this function is called several times, it occurs an error because is trying to delete QTimer that it doesn´t exists.

Another idea please!!

I think I know why - its because your stopall() is called both by the button and by the timer.
So if you click the button, before the timer times out, the slot will be called twice.

I delete QTimer and QTimeLine, in the stopall function, but as this function is called several times, it occurs an error because is trying to delete QTimer that it doesn´t exists.

Right, which is why I wrote in the previous post:

It is better to put initialization in the constructor or an init() function which is called once at start.
