Detailed Description

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 'kapp' global variable. See cut() for an example.

This class provides the following services to all KDE applications.

  • It controls the event queue (see TQApplication ).
  • It provides the application with KDE resources such as accelerators, common menu entries, a TDEConfig 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 TDEApplication'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 TDEApplication'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.

Controls and provides information to all KDE applications.

Constructor & Destructor Documentation

TDEApplication::TDEApplication ( bool  allowStyles = true,
bool  GUIenabled = true,
bool  SMenabled = true 
)

This constructor takes aboutData and command line arguments from TDECmdLineArgs.

If ARGB (transparent) widgets are to be used in your application, please use TDEApplication app(TDEApplication::openX11RGBADisplay()); or TDEApplication app(TDEApplication::openX11RGBADisplay(), useStyles);

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 754 of file tdeapplication.cpp.

TDEApplication::TDEApplication ( int &  argc,
char **  argv,
const TQCString &  rAppName,
bool  allowStyles = true,
bool  GUIenabled = true,
bool  SMenabled = true 
)
Deprecated:
do not use it at all, it will make your application crash, use TDECmdLineArgs

Constructor. Parses command-line arguments.

Parameters:
argc command line argument count
argv command line argument value(s)
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.

Definition at line 3264 of file tdeapplication.cpp.

void TDEApplication::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 TDEAction( i18n( "Clear" ), "edit-clear", 0, kapp, TQT_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 TDEListView 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 TDEListView and reimplement this slot. For example the following code would implement a TDEListView without this behavior:

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

Definition at line 519 of file tdeapplication.cpp.

void TDEApplication::invokeBrowser ( const TQString &  url,
const TQCString &  startup_id 
) [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
startup_id for app startup notification, "0" for none, "" ( empty string ) is the default

Definition at line 93 of file kapplication_win.cpp.

void TDEApplication::invokeBrowser ( const TQString &  url  )  [slot]

Invoke the standard browser.

Uses a startup_id of "" (empty) and is otherwise the same as the above function.

Definition at line 3000 of file tdeapplication.cpp.

void TDEApplication::invokeEditSlot ( const char *  slot  )  [protected]

This method is used internally to determine which edit slots are implemented by the widget that has the focus, and to invoke those slots if available.

Parameters:
slot is the slot as returned using the TQT_SLOT() macro, for example TQT_SLOT( cut() )

This method can be used in TDEApplication subclasses to implement application wide edit actions not supported by the TDEApplication class. For example (in your subclass):

 void MyApplication::deselect()
 {
   invokeEditSlot( TQT_SLOT( deselect() ) );
 }

Now in your application calls to MyApplication::deselect() will call this slot on the focused widget if it provides this slot. You can combine this with TDEAction with:

 KStdAction::deselect( static_cast<MyApplication *>( kapp ), TQT_SLOT( cut() ), actionCollection() );
See also:
cut()
copy()
paste()
clear()
selectAll()

Parameters:
anchor This has to be a defined anchor in your docbook sources. If empty the main index is loaded
appname This allows you to show the help of another application. If empty the current name() is used
startup_id for app startup notification, "0" for none, "" ( empty string ) is the default

Definition at line 77 of file kapplication_win.cpp.

void TDEApplication::invokeHTMLHelp ( const TQString &  aFilename,
const TQString &  aTopic = TQString::null 
) const
Deprecated:
Invoke the khelpcenter HTML help viewer from HTML sources.

bool TDEApplication::isCompositionManagerAvailable (  )  [static]

Gets the availability of a composition manager such as kompmgr Note that at least one application must have called detectCompositionManagerAvailable while the current X display was active in order for this method to return valid results.

See also:
detectCompositionManagerAvailable()
Returns:
whether the composition manager is enabled

Definition at line 2106 of file tdeapplication.cpp.

bool TDEApplication::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 320 of file tdeapplication.h.

bool TDEApplication::isX11CompositionAvailable (  ) 

Returns whether or not X11 composition is available.

You must first call getX11RGBAInformation()

Note that getX11RGBAInformation() has already been called if you used the default TDEApplication constructor.

Additionally, at least one application must have called detectCompositionManagerAvailable while the current X display was active in order for this method to return valid results.

Returns:
true if composition is available

Definition at line 2157 of file tdeapplication.cpp.

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

Returns the current application object.

This is similar to the global TQApplication pointer tqApp. It allows access to the single global TDEApplication 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

TQ_ButtonState TDEApplication::keyboardMouseState (  )  [static]

Returns the state of the currently pressed keyboard modifiers (e.g.

shift, control, etc.) and mouse buttons, similarly to TQKeyEvent::state() and TQMouseEvent::state(). You usually should simply use the information provided by TQKeyEvent and TQMouseEvent, 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 and mouse buttons state
Since:
3.4

Definition at line 3637 of file tdeapplication.cpp.

void TDEApplication::kipcMessage ( int  id,
int  data

TQString TDEApplication::makeStdCaption ( const TQString &  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

Definition at line 2405 of file tdeapplication.cpp.

TQPixmap TDEApplication::miniIcon (  )  const

Returns the mini-icon for the application as a TQPixmap.

void TDEApplication::paste (  )  [slot]

If the widget with focus provides a paste() slot, call that slot.

Thus for a simple application copy can be implemented as:

 KStdAction::paste( kapp, TQT_SLOT( paste() ), actionCollection() );

Definition at line 3034 of file tdeapplication.cpp.

void TDEApplication::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.

Definition at line 1376 of file tdeapplication.cpp.

int TDEApplication::random (  )  [static]

Generates a uniform random number.

Returns:
A truly unpredictable number in the range [0, RAND_MAX)

Definition at line 3395 of file tdeapplication.cpp.

TQString TDEApplication::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

Definition at line 3415 of file tdeapplication.cpp.

void TDEApplication::ref (  )  [slot]

Tells TDEApplication 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).

Definition at line 1249 of file tdeapplication.cpp.

void TDEApplication::removeKipcEventMask ( int  id  ) 

Removes a message type from the KIPC event mask.

This message will not be handled anymore.

Parameters:
id The message id.

Definition at line 534 of file tdeapplication.cpp.

bool TDEApplication::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 1313 of file tdeapplication.cpp.

void TDEApplication::saveState ( TQSessionManager &  sm  ) 

Reimplemented for internal purposes, mainly the highlevel handling of session management with KSessionManaged.

Definition at line 1484 of file tdeapplication.cpp.

void TDEApplication::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 TDEMainWindow. By reimplementing TDEMainWindow::queryClose(), TDEMainWindow::saveProperties() and TDEMainWindow::readProperties() you can simply handle session management for applications with multiple toplevel windows.

For purposes without TDEMainWindow, 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() TDEConfig 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).

void TDEApplication::selectAll (  )  [slot]

If the widget with focus provides a selectAll() slot, call that slot.

Thus for a simple application select all can be implemented as:

 KStdAction::selectAll( kapp, TQT_SLOT( selectAll() ), actionCollection() );

Definition at line 3044 of file tdeapplication.cpp.

TDEConfig * TDEApplication::sessionConfig (  ) 

Returns the application session config object.

Returns:
A pointer to the application's instance specific TDEConfig object.
See also:
TDEConfig

Definition at line 1239 of file tdeapplication.cpp.

bool TDEApplication::sessionSaving (  )  const

Returns true if the application is currently saving its session data (most probably before KDE logout).

This is intended for use mainly in TDEMainWindow::queryClose() and TDEMainWindow::queryExit().

See also:
TDEMainWindow::queryClose
TDEMainWindow::queryExit
Since:
3.1.1

Definition at line 1566 of file tdeapplication.cpp.

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

Emitted when the global settings have been changed - see TDEGlobalSettings TDEApplication takes care of calling reparseConfiguration on TDEGlobal::config() so that applications/classes using this only have to re-read the configuration.

Parameters:
category the category among the enum above
void TDEApplication::setTopWidget ( TQWidget *  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 TDEMainWindow.

Parameters:
topWidget A top widget of the application.
See also:
icon(), caption()

Definition at line 3336 of file tdeapplication.cpp.

void TDEApplication::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.

void TDEApplication::tdedisplayFontChanged (  )  [signal]

Emitted when TDEApplication 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.

Note: If you derive from a QWidget-based class, a faster method is to reimplement TQWidget::fontChange(). This is the preferred way to get informed about font updates.

void TDEApplication::tdedisplayPaletteChanged (  )  [signal]

Emitted when TDEApplication 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 TDEApplication::tdedisplayStyleChanged (  )  [signal]

Emitted when TDEApplication 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.
