/**
|
|
* @short The base class for chat widgets
|
|
*
|
|
* This is the base class for both KChat and KGameChat. KGameChat is the class
|
|
* you want to use if you write a KGame based game as it will do most things for
|
|
* you. KChat is more or less the same but not KGame dependant
|
|
*
|
|
* KChatBase provides a complete chat widget, featuring different sending means
|
|
* (e.g. "send to all", "send to player1", "send to group2" and so on - see
|
|
* addSendingEntry). It also provides full auto-completion capabilities (see
|
|
* TDECompletion and KLineEdit) which defaults to disabled. The user can
|
|
* change this by right-clicking on the KLineEdit widget and selecting the
|
|
* desired behaviour. You can also change this manually by calling
|
|
* setCompletionMode.
|
|
*
|
|
* To make KChatBase useful you have to overwrite at least returnPressed.
|
|
* Here you should send the message to all of your clients (or just some of
|
|
* them, depending on sendingEntry).
|
|
*
|
|
* To add a message just call addMessage with the nickname of the player
|
|
* who sent the message and the message itself. If you don't want to use
|
|
* layoutMessage by any reason you can also call addItem directly. But you
|
|
* should better replace layoutMessage instead.
|
|
*
|
|
* You probably don't want to use the abstract class KChatBase directly but use
|
|
* one of the derived classess KChat or KGameChat. The latter is the
|
|
* widget of choice if you develop a KGame application as you don't have to
|
|
* do anything but providing a KGame object.
