Doubts about QLayout, events and properties

Hello, I've recently started reading the Qt3 documentation, and now I have some doubts.

1. What exactly are layouts, and, for instance, how is a QVBoxLayout different from a QVBox?
2. How are properties different from the usual setMember/getMember methods and when should I use them?
3. In what way are events and event filters different from normal methods and slots?

Thank you.

I hate to RTFM you, but RTFM :) And when you do, come back and ask your questions, because it is most probable, that an answer you get will point you to the docs anyway.

Layouts manage the way that widgets will be placed.

QVBox is a widget with a QVBoxLayout layout.

Using Qt mechanisms you can check at runtime what properties a given object has. You can't do this with methods. You don't have to worry about properties, unless you want to create plugins.

Events are asynchronous and they are first stored in a queue, methods and slots are executed immediately (in Qt4 slots can behave like methods or like event handlers, depending on the connection type).
