[QTime] Create Thread time Mesure

[loic072]

Hi,

I would like mesure with QTime the time between the creation and using thread

In fact, I don't know how retrieve Qtime object in thread? Should it be passed as a thread parameter ?

Or else there is another way without using QTime?

Thank you

regards
Loïc

What does "using thread" mean?

When it starts executing its run() method?

Do you really care how long it takes to start a thread? I would suggest that if your design is such that you are creating/terminating threads often enough that you are concerned with the overhead of doing so, then you should re-think your design... For example, start your thread and then feed it work via emitting a signal, or serializing a data structure like a QVector/QList/QMap, etc. that contains elements from the thread to work on.

Alternatives: use a thread pool or Qt's map/reduce type functionality.

Can you explain why this timing is critical for your needs?
