Closing dialog by QMetaObject::invokeMethod - safe?

but it doesn't work.

Oh, but most important - why my first version don't work?

I believe it "doesn't work" because you do something wrong. If you want a more detailed answer, please provide a more detailed description of what "doesn't work".

In any case, why do you create the dialog before having secured the data from the database? I would have done it the other way around.

Dialog doesn't close, just like this function is not invoked.

It's because i would have to pass all data by constructor arguments, which is a lot.

Well, you can validate data before showing the dialog, that allows you to decide to show or not to show the dialog.

The dialog will only close when control returns to the event loop. We need to see more code to understand what goes wrong.

You can wrap all this data in a nice structure that you pass to the dialog by reference.
