Detailed Description

This class provides a way of getting the QApplication for a DisplayEngine.

Constructor & Destructor Documentation

virtual makVrv::DtQApplicationProvider::~DtQApplicationProvider ( )

virtual

Virtual Destructor.

makVrv::DtQApplicationProvider::DtQApplicationProvider ( DtDe &  de )

protected

Constructor, use the instance function to.

Member Function Documentation

static DtQApplicationProvider& makVrv::DtQApplicationProvider::instance ( DtDe &  de )

static

Get the instance of a DtQApplicationProvider.

static void makVrv::DtQApplicationProvider::registerInstance ( DtDe &  de, DtQApplicationProvider *  instance  )

static

Register the provider with a DtDe.

QApplication* makVrv::DtQApplicationProvider::qAppInstance

(

)

Return a QApplication* creating one if it doesn't exist.

If a QApplication is created, it will be destroyed when this provider is destroyed (at the end of the lifetime of the DtDe instance that created it).

virtual void makVrv::DtQApplicationProvider::setQAppInstance ( QApplication *  app )

virtual

User override of qApp.

virtual void makVrv::DtQApplicationProvider::installEventListener ( )

protectedvirtual

On MS Windows this call installs a low level even listener.

If this is not desired behavior subclass and override this function to be a NO-OP.

virtual void makVrv::DtQApplicationProvider::installTranslators ( )

protectedvirtual

Install translators from the languages install directory.

All installed translators MUST be added to the myTranslators member so they are properly removed and deallocated during destruction.

virtual void makVrv::DtQApplicationProvider::installFont ( )

protectedvirtual

Installs the system wide font.

By default uses the font found in the font manager

static bool makVrv::DtQApplicationProvider::customControlFilter ( void *  message, long *  result  )

staticprotected

NOTE: non-reentrant.
