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
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.

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.

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.

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).

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).

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). |
|
Your application is killed.
Either by your program itself, 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. |
