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.
• 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.

KApplication::KApplication (  Display *    display, int &    argc, char **    argv, const QCString &    rAppName, bool    allowStyles = true, bool    GUIenabled = true )

Constructor. Parses command-line arguments. Use this constructor to use KApplication in a Motif or Xt program. Parameters: display  Will be passed to Qt as the X display. The display must be valid and already opened. rAppName  application name. Will be used for finding the associated message files and icon files, and as the default registration name for DCOP. This is a mandatory parameter. 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. GUIenabled  Set to false to disable all GUI stuff. This implies no styles either.

KApplication::KApplication (  int &    argc, char **    argv, const QCString &    rAppName, bool    allowStyles = true, bool    GUIenabled = true )

Deprecated: // REMOVE FOR KDE 4.0 - using it only gives crashing applications because // KCmdLineArgs::init isn't called Constructor. Parses command-line arguments. Parameters: rAppName  application name. Will be used for finding the associated message files and icon files, and as the default registration name for DCOP. This is a mandatory parameter. 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. GUIenabled  Set to false to disable all GUI stuff. This implies no styles either.

void KApplication::invokeBrowser (  const QString &    url )  [slot]

Invokes the standard browser. Note that you should only do this when you know for sure that the browser can handle the URL (i.e. its mimetype). In doubt, if the URL can point to an image or anything else than directory or HTML, prefer to use new KRun( url ). Parameters: url  The destination address

void KApplication::invokeHelp (  const QString &    anchor = QString::null, const QString &    appname = QString::null )  const

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 197 of file kapplication.h.

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 178 of file kapplication.h. References KApp.

int KApplication::kdeinitExec (  const QString &    name, const QStringList &    args = QStringList(), QString *    error = 0, int *    pid = 0 )  [static]

Starts a program via kdeinit. There will be no application startup notification, so you should use it only for starting internal processes. program name and arguments are converted to according to the local encoding and passed as is to kdeinit. Parameters: name  Name of the program to start args  Arguments to pass to the program error  On failure, error contains a description of the error that occurred. If the pointer is 0, the argument will be ignored pid  On success, the process id of the new service will be written here. If the pointer is 0, the argument will be ignored. Returns: an error code indicating success (== 0) or failure (> 0).

int KApplication::kdeinitExecWait (  const QString &    name, const QStringList &    args = QStringList(), QString *    error = 0, int *    pid = 0 )  [static]

Starts a program via kdeinit and wait for it to finish. Like kdeinitExec(), but it waits till the program is finished. As such it behaves similar to the system(...) function. Parameters: name  Name of the program to start args  Arguments to pass to the program error  On failure, error contains a description of the error that occurred. If the pointer is 0, the argument will be ignored pid  On success, the process id of the new service will be written here. If the pointer is 0, the argument will be ignored. Returns: an error code indicating success (== 0) or failure (> 0).

void KApplication::kdisplayFontChanged (    )  [signal]

Emitted when KApplication has changed its font in response to a KControl request. Normally widgets will update their fonts automatically, but you should connect to this to monitor global font changes, especially if you are using explicit fonts.

void KApplication::kdisplayPaletteChanged (    )  [signal]

Emitted when KApplication has changed its palette due to a KControl request. Normally, widgets will update their palette automatically, but you should connect to this to program special behavior.

void KApplication::kdisplayStyleChanged (    )  [signal]

Emitted when KApplication has changed its GUI style in response to a KControl request. Normally, widgets will update their styles automatically (as they would respond to an explicit setGUIStyle() call), but you should connect to this to program special behavior.

uint KApplication::keyboardModifiers (    )  [static]

Returns the currently pressed keyboard modifiers (e.g. shift, control, etc.) Usually you simply want to test for those in key events, in which case QKeyEvent::state() does the job (or QKeyEvent::key() to notice when a modifier is pressed alone). But it can be useful to query for the status of the modifiers at another moment (e.g. some KDE apps do that upon a drop event). Returns: the keyboard modifiers Since: 3.1

void KApplication::kipcMessage (  int    id, int    data )  [signal]

Emitted when a KIPC user message has been received. Parameters: id  the message id data  the data See also: KIPC , KIPC::Message , addKipcEventMask , removeKipcEventMask

KStyle* KApplication::kstyle (    )  const [inline]

Deprecated: Definition at line 652 of file kapplication.h.

QCString KApplication::launcher (    )  [static]

Returns the DCOP name of the service launcher. This will be something like klaucher_$host_$uid. Returns: the name of the service launcher

QString KApplication::makeStdCaption (  const QString &    userCaption, bool    withAppName = true, bool    modified = false )  const

Builds a caption that contains the application name along with the userCaption() using a standard layout. To make a compliant caption for your window, simply do: setCaption(kapp->makeStdCaption(yourCaption)); Parameters: userCaption  The caption string you want to display in the window caption area. Do not include the application name! withAppName  Indicates that the method shall include or ignore the application name when making the caption string. You are not compliant if you set this to false. modified  If true, a 'modified' sign will be included in the returned string. This is useful when indicating that a file is modified, i.e., it contains data that has not been saved. Returns: the created caption

QPixmap KApplication::miniIcon (    )

Returns the mini-icon for the application as a QPixmap. Returns: the application's mini icon

QString KApplication::miniIconName (    )

Returns the name of the mini-icon for the application. Returns: the mini icon's name

uint KApplication::mouseState (    )  [static]

Returns the currently pressed mouse buttons. Usually you simply want to test for those in mouse events, in which case QMouseEvent::button() does the job (or QMouseEvent::state()). But it can be useful to query for the status of the mouse buttons at another moment. To query for the mouse pointer position, use QCursor::pos(). Returns: the currently pressed mouse buttons Since: 3.1

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.

int KApplication::random (    )  [static]

Generates a uniform random number. Returns: A truly unpredictable number in the range [0, RAND_MAX)

QString KApplication::randomString (  int    length )  [static]

Generates a random string. It operates in the range [A-Za-z0-9] Parameters: length  Generate a string of this length. Returns: the random string

void KApplication::ref (    )  [slot]

Tells KApplication about one more operation that should be finished before the application exits. The standard behavior is to exit on the "last window closed" event, but some events should outlive the last window closed (e.g. a file copy for a file manager, or 'compacting folders on exit' for a mail client).

void KApplication::removeKipcEventMask (  int    id )

Removes a message type from the KIPC event mask. This message will not be handled anymore. Parameters: id  The message id. See also: KIPC , addKipcEventMask() , kipcMessage()

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 sucess, false if the session manager could not be contacted.

void KApplication::saveYourself (    )  [signal]

Session management asks you to save the state of your application. This signal is provided for compatibility only. For new applications, simply use KMainWindow. By reimplementing KMainWindow::queryClose(), KMainWindow::saveProperties() and KMainWindow::readProperties() you can simply handle session management for applications with multiple toplevel windows. For purposes without KMainWindow, create an instance of KSessionManaged and reimplement the functions KSessionManaged::commitData() and/or KSessionManaged::saveState() If you still want to use this signal, here is what you should do: Connect to this signal in order to save your data. Do NOT manipulate the UI in that slot, it is blocked by the session manager. Use the sessionConfig() KConfig object to store all your instance specific data. Do not do any closing at this point! The user may still select Cancel wanting to continue working with your application. Cleanups could be done after shutDown() (see the following).

KConfig* KApplication::sessionConfig (    )

Returns the application session config object. Returns: A pointer to the application's instance specific KConfig object. See also: KConfig

bool KApplication::sessionSaving (    )

Returns true if the application is currently saving its session data (most probably before KDE logout). This is intended for use mainly in KMainWindow::queryClose() and KMainWindow::queryExit(). See also: KMainWindow::queryClose , KMainWindow::queryExit Since: 3.1.1

void KApplication::setStartupId (  const QCString &    startup_id )

Sets a new value for the application startup notification window property for newly created toplevel windows. Parameters: the  startup notification identifier

void KApplication::settingsChanged (  int    category )  [signal]

Emitted when the global settings have been changed - see KGlobalSettings KApplication takes care of calling reparseConfiguration on KGlobal::config() so that applications/classes using this only have to re-read the configuration Parameters: category  the category among the enum above

void KApplication::setTopWidget (  QWidget *    topWidget )

Sets the top widget of the application. This means basically applying the right window caption and icon. An application may have several top widgets. You don't need to call this function manually when using KMainWindow. Parameters: topWidget  A top widget of the application. See also: icon(), caption()

void KApplication::shutDown (    )  [signal]

Your application is killed. Either by your program itself, xkill or (the usual case) by KDE's logout. The signal is particularly useful if your application has to do some last-second cleanups. Note that no user interaction is possible at this state.

int KApplication::startServiceByDesktopName (  const QString &    _name, const QStringList &    URLs = QStringList(), QString *    error = 0, QCString *    dcopService = 0, int *    pid = 0, const QCString &    startup_id = "", bool    noWait = false )  [static]

If empty, the service does not provide DCOP services. If the pointer is 0 the argument will be ignored pid  On success, the process id of the new service will be written here. If the pointer is 0, the argument will be ignored. startup_id  for app startup notification, "0" for none, "" ( empty string ) is the default noWait  if set, the function does not wait till the service is running. Returns: an error code indicating success (== 0) or failure (> 0).

int KApplication::startServiceByDesktopName (  const QString &    _name, const QString &    URL, QString *    error = 0, QCString *    dcopService = 0, int *    pid = 0, const QCString &    startup_id = "", bool    noWait = false )  [static]

"Applications/konqueror.desktop" or "/home/user/bla/myfile.desktop" Parameters: name  the path of the desktop file URL  if not empty this URL is passed to the service error  On failure, error contains a description of the error that occurred. If the pointer is 0, the argument will be ignored dcopService  On success, dcopService contains the DCOP name under which this service is available. If empty, the service does not provide DCOP services. If the pointer is 0 the argument will be ignored pid  On success, the process id of the new service will be written here. If the pointer is 0, the argument will be ignored. startup_id  for app startup notification, "0" for none, "" ( empty string ) is the default noWait  if set, the function does not wait till the service is running. Returns: an error code indicating success (== 0) or failure (> 0).
