Detailed Description

widget displaying text, supports pango attribute syntax

signal id	signature	emitted when...
Signals inherited from Widget
realize	(Label&, (Data_t)) -> void	Widget is realized, usually right before it is drawn for the first time
unrealize	(Label&, (Data_t)) -> void	Widget is unmapped and will no longer be drawn
destroy	(Label&, (Data_t)) -> void	Widgets internal state is deallocated, calling Widget::~Widget() may not necessarily emit this signal
hide	(Label&, (Data_t)) -> void	Widget is actively hidden, leaves the visible area of the window, or its opacity is set to 0
show	(Label&, (Data_t)) -> void	Widget is drawn for the first time after being realized
map	(Label&, (Data_t)) -> void	Widget is mapped, this happens the first time it and all its parents become visible
unmap	(Label&, (Data_t)) -> void	Widget and all of its parents become hidden
