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.
The way a service gets started depends on the 'X-DCOP-ServiceType' entry in the desktop file of the service:
There are three possibilities:
| enum CaptionLayout { CaptionAppLast=1, CaptionAppFirst, CaptionNoApp } | CaptionLayout |
| KApplication ( bool allowStyles=true, bool GUIenabled=true)
| KApplication |
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 (Display *display, int& argc, char** argv, const QCString& rAppName,
bool allowStyles=true, bool GUIenabled=true)
| KApplication |
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 (int& argc, char** argv,
const QCString& rAppName, bool allowStyles=true, bool GUIenabled=true)
| KApplication |
// 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 addCmdLineOptions ()
| addCmdLineOptions |
[static]
Add Qt and KDE command line options to KCmdLineArgs.
| ~KApplication ()
| ~KApplication |
[virtual]
| KApplication* kApplication ()
| kApplication |
[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
| KConfig* sessionConfig ()
| sessionConfig |
Returns the application session config object.
Returns: A pointer to the application's instance specific KConfig object.
See also: KConfig
| bool isRestored ()
| isRestored |
[const]
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()
| void disableSessionManagement ()
| disableSessionManagement |
Disables session management for this application.
Useful in case your application is started by the initial "startkde" script.
| enum ShutdownConfirm { ShutdownConfirmDefault = -1, /** } | ShutdownConfirm |
Obey the user's confirmation setting.
| enum ShutdownType { ShutdownTypeDefault = -1, /** } | ShutdownType |
Select previous action or the default if it's the first time.
| enum ShutdownMode { ShutdownModeDefault = -1, /** } | ShutdownMode |
Select previous mode or the default if it's the first time.
| bool requestShutDown ( ShutdownConfirm confirm = ShutdownConfirmDefault,
ShutdownType sdtype = ShutdownTypeDefault,
ShutdownMode sdmode = ShutdownModeDefault )
| requestShutDown |
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 propagateSessionManager ()
| 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.
| void commitData ( QSessionManager& sm )
| commitData |
Reimplemented from QApplication.
| void saveState ( QSessionManager& sm )
| saveState |
Reimplemented from QApplication.

| uint keyboardModifiers ()
| 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
| enum { Button1Pressed = 1<<8, Button2Pressed = 1<<9, Button3Pressed = 1<<10, Button4Pressed = 1<<11, Button5Pressed = 1<<12 } |

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
| void ref ()
| 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 deref ()
| deref |
[slot]

| void kdisplayStyleChanged ()
| 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.
| void kdisplayFontChanged ()
| 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 appearanceChanged ()
| appearanceChanged |
[signal]
Emitted when KApplication has changed either its GUI style, its font or its palette in response to a kdisplay request. Normally, widgets will update their styles automatically, but you should connect to this to program special behavior.

Parameters:
| category | the category among the enum above |
| void iconChanged (int group)
| iconChanged |
[signal]
Emitted when the global icon settings have been changed.

| void saveYourself ()
| 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).
| void shutDown ()
| shutDown |
[signal]
