//!\brief Scroll area showing part of the chat messages for a given buffer.
33
/** The contents of the scroll area, i.e. a widget of type ChatWidgetContents,
34
* needs to be provided by calling init(). We don't create this widget ourselves, because
35
* while a ChatWidget will be destroyed and recreated quite often (for example when switching
36
* buffers), there ususally is no need to re-render its content every time (which can be time-consuming).
37
* Before a ChatWidget is destroyed, it gives up its ownership of its contents, referring responsibility
38
* back to where it came from.
40
* Because we use this as a custom widget in Qt Designer, we cannot use a constructor that takes custom
41
* parameters. Instead, it is mandatory to call init() before using this widget.
