ProcessEventsFlag Inguments inocumentado en QT

Question

Noté que los diálogos modales en QT usan un QEVENTLOOP local con el conjunto de procesosEventflags como "DIALOGEXEC"

eventLoop.exec(QEventLoop::DialogExec);

El asistente QT no tiene información sobre lo que significa este enumeración.Hay otro llamado EventLoopexec.¿Alguien tiene alguna idea de lo que realmente quiere decir y por qué no están documentados?

gracias

I did some poking around and this is what I found:

• This enum is intentionally omitted from the documentation, along with several other QEventLoop::ProcessEventsFlag enum values (X11ExcludeTimers, ExcludeUserInput, WaitForMore, EventLoopExec) as there is an \omitvalue in front of each one in the comments that generate the docs.

• There is only one place in all of Qt that actually uses it, in qeventdispatcher_mac.mm in which it appears to be some kind of mac-specific optimization according to the in-line comments

The intentional omission of these values from the docs leads me to conclude that they're for internal Qt use only, and that you shouldn't need to use them or worry about them.
