\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.
