/**
|
|
* This class implements a very simple IPC mechanism for KDE. You can send
|
|
* a message of a predefined type to either a specific application, or to all
|
|
* KDE application on the current display. The message can carry one integer of
|
|
* data.
|
|
*
|
|
* KIPC is mainly used in KDE for sending "Change Messages", i.e. a message to
|
|
* all KDE apps that a certain setting (the font, for example) has changed.
|
|
* For anything more complex it is recommended to use DCOP -- the Desktop
|
|
* Communications Protocol.
|
|
*
|
|
* Messages with id code < 32 are called "System Messages". These are
|
|
* directly handled by KApplication. Examples are: PaletteChanged and
|
|
* StyleChanged. Messages with id code >= 32 are user messages. KApplication
|
|
* emits the signal kipcMessage(id,arg) for each user message it receives.
|
|
*
|
|
* KIPC is implemented using X11 ClientMessage events.
|

* @see KApplication::kipcMessage()
