TPlatformServices = class
class PASCALIMPLEMENTATION TPlatformServices : public System::TObject
Is a class that can be used to determine the services that are available on the platform on which your application is running.
Use TPlatformServices in order to determine the services that are available on the run-time platform, and also to enable and use those services in your application. For instance, you could check if a virtual keyboard service is available on an OS X running computer and the results would be negative, while on Windows the virtual keyboard service is available.
