Detailed Description

ApplicationLauncherJob runs an application and watches it while running.

It creates a startup notification and finishes it on success or on error (for the taskbar). It also emits an error message if necessary (e.g. "program not found").

When passing multiple URLs to an application that doesn't support opening multiple files, the application will be launched once for each URL.

The job finishes when the application is successfully started. At that point you can query the PID(s).

For error handling, either connect to the result() signal, or for a simple messagebox on error, you can use:

// Since 5.98 use:
// For older releases use:
A UI delegate tuned to be used with KIO Jobs.
KIOCORE_EXPORT KJobUiDelegate * createDefaultJobUiDelegate()
Convenience method: use default factory, if there's one, to create a delegate and return it.

Using JobUiDelegate (which is widgets based) also enables the feature of asking the user in case the executable or desktop file isn't marked as executable. Otherwise the job will just refuse executing such files.

To invoke the open-with dialog (from KIOWidgets), construct an ApplicationLauncherJob without any arguments or with a null KService.

the URLs passed to the service will be deleted when it exits (if the URLs are local files)

Constructor & Destructor Documentation

◆ ApplicationLauncherJob() [1/4]

KIO::ApplicationLauncherJob::ApplicationLauncherJob ( const KService::Ptr & service,
QObject * parent = nullptr )
explicit

Creates an ApplicationLauncherJob.

Parameters
servicethe service (application desktop file) to run
parentthe parent QObject

Definition at line 62 of file applicationlauncherjob.cpp.

◆ ApplicationLauncherJob() [2/4]

KIO::ApplicationLauncherJob::ApplicationLauncherJob ( const KServiceAction & serviceAction,
QObject * parent = nullptr )
explicit

Creates an ApplicationLauncherJob.

Parameters
serviceActionthe service action to run
parentthe parent QObject

Definition at line 72 of file applicationlauncherjob.cpp.

◆ ApplicationLauncherJob() [3/4]

KIO::ApplicationLauncherJob::ApplicationLauncherJob ( const KDesktopFileAction & desktopFileAction,
QObject * parent = nullptr )
explicit

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

Since
6.0

Definition at line 79 of file applicationlauncherjob.cpp.

◆ ApplicationLauncherJob() [4/4]

KIO::ApplicationLauncherJob::ApplicationLauncherJob ( QObject * parent = nullptr)
explicit

Creates an ApplicationLauncherJob which will prompt the user for which application to use (via the open-with dialog from KIOWidgets).

Parameters
parentthe parent QObject
Since
5.71

Definition at line 87 of file applicationlauncherjob.cpp.

◆ ~ApplicationLauncherJob()

KIO::ApplicationLauncherJob::~ApplicationLauncherJob ( )
override

Destructor.

Note that jobs auto-delete themselves after emitting result. Deleting/killing the job will not stop the started application.

Definition at line 93 of file applicationlauncherjob.cpp.

Member Function Documentation

◆ pid()

qint64 KIO::ApplicationLauncherJob::pid ( ) const
Returns
the PID of the application that was started

Convenience method for pids().at(0). You should only use this when specifying zero or one URL, or when you are sure that the application supports opening multiple files. Otherwise use pids(). Available after the job emits result().

Definition at line 267 of file applicationlauncherjob.cpp.

◆ pids()

QList< qint64 > KIO::ApplicationLauncherJob::pids ( ) const
Returns
the PIDs of the applications that were started

Available after the job emits result().

Definition at line 272 of file applicationlauncherjob.cpp.

◆ setRunFlags()

void KIO::ApplicationLauncherJob::setRunFlags ( RunFlags runFlags)

Specifies various flags.

Parameters
runFlagsthe flags to be set. For instance, whether the URLs are temporary files that should be deleted after execution.

Definition at line 104 of file applicationlauncherjob.cpp.

◆ setStartupId()

void KIO::ApplicationLauncherJob::setStartupId ( const QByteArray & startupId)

Sets the platform-specific startup id of the application launch.

Parameters
startupIdstartup id, if any (otherwise ""). For X11, this would be the id for the Startup Notification protocol. For Wayland, this would be the token for the XDG Activation protocol.

Definition at line 114 of file applicationlauncherjob.cpp.

◆ setSuggestedFileName()

void KIO::ApplicationLauncherJob::setSuggestedFileName ( const QString & suggestedFileName)

Sets the file name to use in the case of downloading the file to a tempfile in order to give to a non-URL-aware application.

Some apps rely on the extension to determine the MIME type of the file. Usually the file name comes from the URL, but in the case of the HTTP Content-Disposition header, we need to override the file name.

Parameters
suggestedFileNamethe file name

Definition at line 109 of file applicationlauncherjob.cpp.

◆ setUrls()

void KIO::ApplicationLauncherJob::setUrls ( const QList< QUrl > & urls)

Specifies the URLs to be passed to the application.

Parameters
urlslist of files (local or remote) to open

Note that when passing multiple URLs to an application that doesn't support opening multiple files, the application will be launched once for each URL.

Definition at line 99 of file applicationlauncherjob.cpp.

◆ start()

void KIO::ApplicationLauncherJob::start ( )
overridevirtual

Starts the job.

You must call this, after having done all the setters. This is (potentially) a GUI job, never use exec(), it would block user interaction.

Implements KJob.
