Does Winid function of Qwidget class will work in different platform?
It will work on Linux and mac or we have to change the code?
It is available on all supported platforms but the type of the id differs. See the "documentation":http://doc.qt.nokia.com/stable/qwidget.html#winId.
[quote]Portable in principle, but if you use it you are probably about to do something non-portable. Be careful.[/quote]
