29 //!\brief Scroll area showing part of the chat messages for a given buffer.
30 /** The contents of the scroll area, i.e. a widget of type ChatWidgetContents,
31 * needs to be provided by calling init(). We don't create this widget ourselves, because
32 * while a ChatWidget will be destroyed and recreated quite often (for example when switching
33 * buffers), there ususally is no need to re-render its content every time (which can be time-consuming).
34 * Before a ChatWidget is destroyed, it gives up its ownership of its contents, referring responsibility
35 * back to where it came from.
37 * Because we use this as a custom widget in Qt Designer, we cannot use a constructor that takes custom
38 * parameters. Instead, it is mandatory to call init() before using this widget.
