\class QtSingleApplication qtsingleapplication.h |
|
||||||
\brief The QtSingleApplication class provides an API to detect and |
|
||||||
communicate with running instances of an application. |
|
||||||
|
|
||||||
This class allows you to create applications where only one |
|
||||||
instance should be running at a time. I.e., if the user tries to |
|
||||||
launch another instance, the already running instance will be |
|
||||||
activated instead. Another usecase is a client-server system, |
|
||||||
where the first started instance will assume the role of server, |
|
||||||
and the later instances will act as clients of that server. |
|
||||||
|
|
||||||
By default, the full path of the executable file is used to |
|
||||||
determine whether two processes are instances of the same |
|
||||||
application. You can also provide an explicit identifier string |
|
||||||
that will be compared instead. |
|
||||||
|
|
||||||
The application should create the QtSingleApplication object early |
|
||||||
in the startup phase, and call isRunning() to find out if another |
|
||||||
instance of this application is already running. If isRunning() |
|
||||||
returns false, it means that no other instance is running, and |
|
||||||
this instance has assumed the role as the running instance. In |
|
||||||
this case, the application should continue with the initialization |
|
||||||
of the application user interface before entering the event loop |
|
||||||
with exec(), as normal. |
|
||||||
|
|
||||||
The messageReceived() signal will be emitted when the running |
|
||||||
application receives messages from another instance of the same |
|
||||||
application. When a message is received it might be helpful to the |
|
||||||
user to raise the application so that it becomes visible. To |
|
||||||
facilitate this, QtSingleApplication provides the |
|
||||||
setActivationWindow() function and the activateWindow() slot. |
|
||||||
|
|
||||||
If isRunning() returns true, another instance is already |
|
||||||
running. It may be alerted to the fact that another instance has |
|
||||||
started by using the sendMessage() function. Also data such as |
|
||||||
startup parameters (e.g. the name of the file the user wanted this |
|
||||||
new instance to open) can be passed to the running instance with |
|
||||||
this function. Then, the application should terminate (or enter |
|
||||||
client mode). |
|
||||||
|
|
||||||
If isRunning() returns true, but sendMessage() fails, that is an |
|
||||||
indication that the running instance is frozen. |
|
||||||
|
|
||||||
Here's an example that shows how to convert an existing |
|
||||||
application to use QtSingleApplication. It is very simple and does |
|
||||||
not make use of all QtSingleApplication's functionality (see the |
|
||||||
examples for that). |
|
||||||
|
|
||||||
\code |
|
||||||
// Original
|
|
||||||
int main(int argc, char **argv) |
|
||||||
{ |
|
||||||
QApplication app(argc, argv); |
|
||||||
|
|
||||||
MyMainWidget mmw; |
|
||||||
mmw.show(); |
|
||||||
return app.exec(); |
|
||||||
} |
|
||||||
|
|
||||||
// Single instance
|
|
||||||
int main(int argc, char **argv) |
|
||||||
{ |
|
||||||
QtSingleApplication app(argc, argv); |
|
||||||
|
|
||||||
if (app.isRunning()) |
|
||||||
return !app.sendMessage(someDataString); |
|
||||||
|
|
||||||
MyMainWidget mmw; |
|
||||||
app.setActivationWindow(&mmw); |
|
||||||
mmw.show(); |
|
||||||
return app.exec(); |
|
||||||
} |
|
||||||
\endcode |
|
||||||
|
|
||||||
Once this QtSingleApplication instance is destroyed (normally when |
|
||||||
the process exits or crashes), when the user next attempts to run the |
|
||||||
application this instance will not, of course, be encountered. The |
|
||||||
next instance to call isRunning() or sendMessage() will assume the |
|
||||||
role as the new running instance. |
|
||||||
|
|
||||||
For console (non-GUI) applications, QtSingleCoreApplication may be |
|
||||||
used instead of this class, to avoid the dependency on the QtGui |
|
||||||
library. |
|
||||||

\class QtSingleCoreApplication qtsinglecoreapplication.h |
|
||||||
\brief A variant of the QtSingleApplication class for non-GUI applications. |
|
||||||
|
|
||||||
This class is a variant of QtSingleApplication suited for use in |
|
||||||
console (non-GUI) applications. It is an extension of |
|
||||||
QCoreApplication (instead of QApplication). It does not require |
|
||||||
the QtGui library. |
|
||||||
|
|
||||||
The API and usage is identical to QtSingleApplication, except that |
|
||||||
functions relating to the "activation window" are not present, for |
|
||||||
obvious reasons. Please refer to the QtSingleApplication |
|
||||||
documentation for explanation of the usage. |
|
||||||
|
|
||||||
A QtSingleCoreApplication instance can communicate to a |
|
||||||
QtSingleApplication instance if they share the same application |
|
||||||
id. Hence, this class can be used to create a light-weight |
|
||||||
command-line tool that sends commands to a GUI application. |
