Detailed Description

Constructor & Destructor Documentation

virtual makVrv::DtQApplicationProvider::~DtQApplicationProvider ( ) [virtual]

Virtual Destructor.

makVrv::DtQApplicationProvider::DtQApplicationProvider ( DtDe & de ) [protected]

Constructor, use the instance function to.

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 ( ) [protected, virtual]

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 ( ) [protected, virtual]

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 ( ) [protected, virtual]

Installs the system wide font.

By default uses the font found in the font manager

static bool makVrv::DtQApplicationProvider::customControlFilter	(	void *	message,
		long *	result
	)		`[static, protected]`

NOTE: non-reentrant.
