Detailed Description

Controls and provides information to all KDE applications. Controls and provides information to all KDE applications.

Only one object of this class can be instantiated in a single app. This instance is always accessible via the kApplication() method.

This class provides the following services to all KDE applications.

It controls the event queue (see QApplication ).
It provides the application with KDE resources such as accelerators, common menu entries, a KConfig object. session management events, help invocation etc.
Installs a signal handler for the SIGCHLD signal in order to avoid zombie children. If you want to catch this signal yourself or don't want it to be caught at all, you have set a new signal handler (or SIG_IGN) after KApplication's constructor has run.
Installs an empty signal handler for the SIGPIPE signal using installSigpipeHandler(). If you want to catch this signal yourself, you have set a new signal handler after KApplication's constructor has run.
It can start new services

The way a service gets started depends on the 'X-DCOP-ServiceType' entry in the desktop file of the service:

There are three possibilities:

X-DCOP-ServiceType=None (default) Always start a new service, don't wait till the service registers with dcop.
X-DCOP-ServiceType=Multi Always start a new service, wait until the service has registered with dcop.
X-DCOP-ServiceType=Unique Only start the service if it isn't already running, wait until the service has registered with dcop.

Constructor & Destructor Documentation

KApplication::KApplication ( bool allowStyles = true,

bool GUIenabled = true

)

This constructor takes aboutData and command line arguments from KCmdLineArgs.

Parameters:

allowStyles Set to false to disable the loading on plugin based styles. This is only useful to applications that do not display a GUI normally. If you do create an application with allowStyles set to false it normally runs in the background but under special circumstances displays widgets. Call enableStyles() before displaying any widgets.

GUIenabled Set to false to disable all GUI stuff. This implies no styles either.

Definition at line 560 of file kapplication.cpp.
References installSigpipeHandler(), and KInstance::instanceName().

KApplication::KApplication ( Display * display,

Qt::HANDLE visual = 0,

Qt::HANDLE colormap = 0,

bool allowStyles = true

)

Constructor.
Parses command-line arguments. Use this constructor when you you need to use a non-default visual or colormap.

Parameters:

display Will be passed to Qt as the X display. The display must be valid and already opened.

visual A pointer to the X11 visual that should be used by the appliction. Note that only TrueColor visuals are supported on depths greater than 8 bpp. If this parameter is NULL, the default visual will be used instead.

colormap The colormap that should be used by the application. If this parameter is 0, the default colormap will be used instead.

allowStyles Set to false to disable the loading on plugin based styles. This is only useful to applications that do not display a GUI normally. If you do create an application with allowStyles set to false that normally runs in the background but under special circumstances displays widgets call enableStyles() before displaying any widgets.

Member Function Documentation

void KApplication::addCmdLineOptions ( ) [static]

Add Qt and KDE command line options to KCmdLineArgs.

Reimplemented in KUniqueApplication.
Definition at line 1357 of file kapplication.cpp.
References KCmdLineArgs::addCmdLineOptions().
Referenced by KCmdLineArgs::init().

KApplication* KApplication::kApplication ( ) [inline, static]

Returns the current application object.
This is similar to the global QApplication pointer qApp. It allows access to the single global KApplication object, since more than one cannot be created in the same application. It saves you the trouble of having to pass the pointer explicitly to every function that may require it.
Returns:
the current application object

Definition at line 217 of file kapplication.h.
References KApp.

KConfig * KApplication::sessionConfig ( )

Returns the application session config object.

Returns:
A pointer to the application's instance specific KConfig object.

See also:
KConfig

Definition at line 934 of file kapplication.cpp.

bool KApplication::isRestored ( ) const [inline]

Is the application restored from the session manager?

Returns:
If true, this application was restored by the session manager. Note that this may mean the config object returned by sessionConfig() contains data saved by a session closedown.

See also:
sessionConfig()

Definition at line 236 of file kapplication.h.
References QApplication::isSessionRestored().
Referenced by KUniqueApplication::restoringSession().

void KApplication::disableSessionManagement ( )

Disables session management for this application.
Useful in case your application is started by the initial "startkde" script.
Definition at line 980 of file kapplication.cpp.

void KApplication::enableSessionManagement ( )

Enables again session management for this application, formerly disabled by calling disableSessionManagement().
You usually shouldn't call this function, as the session management is enabled by default.
Definition at line 984 of file kapplication.cpp.

bool KApplication::requestShutDown ( ShutdownConfirm confirm = ShutdownConfirmDefault,

ShutdownType sdtype = ShutdownTypeDefault,

ShutdownMode sdmode = ShutdownModeDefault

)

Asks the session manager to shut the session down.
Using confirm == ShutdownConfirmYes or sdtype != ShutdownTypeDefault or sdmode != ShutdownModeDefault causes the use of ksmserver's DCOP interface. The remaining two combinations use the standard XSMP and will work with any session manager compliant with it.

Parameters:

confirm Whether to ask the user if he really wants to log out. ShutdownConfirm

sdtype The action to take after logging out. ShutdownType

sdmode If/When the action should be taken. ShutdownMode

Returns:
true on success, false if the session manager could not be contacted.

Definition at line 1006 of file kapplication.cpp.
References dcopClient(), QCString::isEmpty(), propagateSessionManager(), DCOPClient::send(), ShutdownConfirmNo, ShutdownConfirmYes, ShutdownModeDefault, ShutdownTypeDefault, and QApplication::syncX().

void KApplication::propagateSessionManager ( )

Propagates the network address of the session manager in the SESSION_MANAGER environment variable so that child processes can pick it up.
If SESSION_MANAGER isn't defined yet, the address is searched in $HOME/.KSMserver.
This function is called by clients that are started outside the session ( i.e. before ksmserver is started), but want to launch other processes that should participate in the session. Examples are kdesktop or kicker.

KMainWindow::queryClose
KMainWindow::queryExit

Since:
3.1.1

Definition at line 1242 of file kapplication.cpp.

DCOPClient * KApplication::dcopClient ( ) [static]

Returns a pointer to a DCOPClient for the application.
If a client does not exist yet, it is created when this function is called.
Returns:
the DCOPClient for the application

void KApplication::clear ( ) [slot]

If the widget with focus provides a clear() slot, call that slot.
Thus for a simple application clear() can be implemented as:
new KAction( i18n( "Clear" ), "editclear", 0, kapp, SLOT( clear() ), actionCollection(), "clear" );
Note that for some widgets, this may not provide the intended bahavior. For example if you make use of the code above and a KListView has the focus, clear() will clear all of the items in the list. If this is not the intened behavior and you want to make use of this slot, you can subclass KListView and reimplement this slot. For example the following code would implement a KListView without this behavior:

class MyListView : public KListView { Q_OBJECT public: MyListView( QWidget * parent = 0, const char * name = 0, WFlags f = 0 ) : KListView( parent, name, f ) {} virtual ~MyListView() {} public slots: virtual void clear() {} };
