Integrate the GuiPlatformPlugin interface
This is an internal interface for plugins that can be provided by the platform to give platform-specific features by platforms built on top of Qt. We can easlily integrate Qt on Windows, Mac, Gnome, ... without any plugin because we can link to their respective library (dynamically if we don't want to depend on it). On Gnome, we can dynamically resolve Gtk+ symbols. This is however not possible for KDE or other platform built on top of Qt: we can't link against their library because they depend on us and we can't dynamically resolve the symbols because they are mangled (C++) So this plugin provides hooks inside Qt to be able to do things like native File or Color dialog, native icons, accurate reading of the config file, and so on. This is currently private API. Task-number: QT-406 Reviewed-by: Jens Bache-Wiig Reviewed-by: Oswald Buddenhagen
