Detailed Description

CommandLauncherJob runs a command 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").

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

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

job->setUiDelegate(new KDialogJobUiDelegate(KJobUiDelegate::AutoHandlingEnabled, this));

Constructor & Destructor Documentation

KIO::CommandLauncherJob::CommandLauncherJob ( const QString &  command, QObject *  parent = nullptr  )

explicit

Creates a CommandLauncherJob.

Parameters

command	the shell command to run The command is given "as is" to the shell, it must already be quoted if necessary. If command is instead a filename, consider using the other constructor, even if no args are present.
parent	the parent QObject

Please consider also calling setDesktopName(), or setExecutable() and setIcon() for better startup notification.

Definition at line 28 of file commandlauncherjob.cpp.

KIO::CommandLauncherJob::CommandLauncherJob ( const QString &  executable, const QStringList &  args, QObject *  parent = nullptr  )

explicit

Creates a CommandLauncherJob.

Parameters

executable	the name of the executable
args	the commandline arguments to pass to the executable
parent	the parent QObject

Please consider also calling setDesktopName(), or setExecutable() and setIcon() for better startup notification.

Definition at line 35 of file commandlauncherjob.cpp.

KIO::CommandLauncherJob::~CommandLauncherJob ( )

override

Destructor.

Note that jobs auto-delete themselves after emitting result

Definition at line 43 of file commandlauncherjob.cpp.

Member Function Documentation

qint64 KIO::CommandLauncherJob::pid

(

)

const

Returns

the PID of the application that was started

Available after the job emits result().

Definition at line 124 of file commandlauncherjob.cpp.

void KIO::CommandLauncherJob::setDesktopName

(

const QString &

desktopName

)

Set the name of the desktop file (e.g. "org.kde.dolphin", the extension is optional).

This is an alternative solution for setIcon() and setExecutable(), i.e. the icon will be taken from the desktop file, and the executable inferred from the "Exec" line.

Definition at line 59 of file commandlauncherjob.cpp.

void KIO::CommandLauncherJob::setExecutable

(

const QString &

executable

)

Sets the name of the executable, used in the startup notification (see KStartupInfoData::setBin()).

Parameters

executable

executable name, with or without a path

Alternatively, use setDesktopName().

Definition at line 49 of file commandlauncherjob.cpp.

void KIO::CommandLauncherJob::setIcon

(

const QString &

iconName

)

Sets the icon for the startup notification.

Parameters

iconName

name of the icon, to be loaded from the current icon theme

Alternatively, use setDesktopName().

Definition at line 54 of file commandlauncherjob.cpp.

void KIO::CommandLauncherJob::setProcessEnvironment

(

const QProcessEnvironment &

environment

)

Sets the environment that will be passed to the child process.

Can be used to pass environment variables to the child process.

Parameters

environment

set of environment variables to pass to the child process

See also

QProcessEnvironment

Since

5.82

Definition at line 74 of file commandlauncherjob.cpp.

void KIO::CommandLauncherJob::setStartupId

(

const QByteArray &

startupId

)

Sets the startup notification id of the command launch.

Parameters

startupId

startup notification id, if any (otherwise "").

Definition at line 64 of file commandlauncherjob.cpp.

void KIO::CommandLauncherJob::setWorkingDirectory

(

const QString &

workingDirectory

)

Sets the working directory from which to run the command.

Parameters

workingDirectory

path of a local directory

Definition at line 69 of file commandlauncherjob.cpp.

void KIO::CommandLauncherJob::start ( )

overridevirtual

Starts the job.

You must call this, after having done all the setters.

Implements KJob.
