[SOLVED] How do you create a new event?

[Jose Antonio]

I would know like to do a new event to use QEvent::user

In particular, how do you do an event, when you change a variable?

Hi, and welcome to the Qt Dev Net!

For detecting change of variables, you should use Signals and Slots instead of events. That way, you don't need to subclass of QEvent.

Firstly, thanks for your help, but I have a problem I don't know very well QEvent::user, and I need create my own event with QEvent for a interruption.

Thanks for all.

Hi,
you need to create a custom class that inherits QEvent and register it with QEvent::registerEventType(). You can then post events with QCoreApplication::sendEvent() or QCoreApplication::postEvent().

And the condition of the event, in my case when variable = 1 wherein do it carey?

[Guest]

You can put it in a member variable of your event class:

class MyEvent: public QEvent
{
    // ...
    bool myCondition;
};
