Functions
GCF::Result	GCF::ipcConnect (QObject *sender, const char *signal, GCF::IpcRemoteObject *receiver, const char *member)
GCF::Result	GCF::ipcConnect (GCF::IpcRemoteObject *sender, const char *signal, QObject *receiver, const char *member)

Detailed Description

The "GCF IPC Module" extends offers support for inter-process communication in your GCF applications.

Using this module you can remotely invoke methods on objects offered by components in another application. You can also create remote signal/slot connections! Please read the article on Using IPC in your applications to know more about this.

To include this module in GCF you can add the following line to your project file

CONFIG += GCFIpc3

For this to work, you should have set QMAKEFEATURES environment variable to $GCFDIR/QMakePRF. If you have not configured the QMAKEFEATURES, you can enter the following line in your project file instead.

GCF_SOURCE_DIR = /path/to/gcf/source/
include( $$GCF_SOURCE_DIR/QMakePRF/GCFIpc3.prf )

Function Documentation

GCF::Result GCF::ipcConnect	(	QObject *	sender,
		const char *	signal,
		GCF::IpcRemoteObject *	receiver,
		const char *	member
	)

Connects signal of local QObject sender to member of remote object receiver.

This function returns true upon success. False+error message upon failure.

GCF::Result GCF::ipcConnect	(	GCF::IpcRemoteObject *	sender,
		const char *	signal,
		QObject *	receiver,
		const char *	member
	)

Connects signal of remote object sender to member of local QObject receiver.

This function returns true upon success. False+error message upon failure.

GCF::Result GCF::ipcConnect	(	QObject *	sender,
		const char *	signal,
		const QHostAddress &	addr,
		quint16	port,
		const QString &	object,
		const QString &	method
	)

Connects signal of local QObject sender to method of a remote object by name object available at port and addr address.

This function returns true upon success. False+error message upon failure.
