\title Loading Documents
The application in this example loads or prints the documents
passed as commandline parameters to further instances of this
application.
\quotefromfile loader/main.cpp
\printuntil };
The user interface in this application is a QMainWindow subclass
with a QMdiArea as the central widget. It implements a slot
\c handleMessage() that will be connected to the messageReceived()
signal of the QtSingleApplication class.
\printuntil }
The MainWindow constructor creates a minimal user interface.
\printto case Print:
The handleMessage() slot interprets the message passed in as a
filename that can be prepended with \e /print to indicate that
the file should just be printed rather than loaded.
\printto #include
Loading the file will also activate the window.
\printto mw
The \c main entry point function creates a QtSingleApplication
object, and creates a message to send to a running instance
of the application. If the message was sent successfully the
process exits immediately.
\printuntil }
If the message could not be sent the application starts up. Note
that \c false is passed to the call to setActivationWindow() to
prevent automatic activation for every message received, e.g. when
the application should just print a file. Instead, the message
handling function determines whether activation is requested, and
signals that by emitting the needToShow() signal. This is then
simply connected directly to QtSingleApplication's
activateWindow() slot.
