by clear().
+ \warning When passing a QString to the constructor or calling setText(),
+ make sure to sanitize your input, as QLabel tries to guess whether it
+ displays the text as plain text or as rich text. You may want to call
+ setTextFormat() explicitly, e.g. in case you expect the text to be in
+ plain format but cannot control the text source (for instance when
+ displaying data loaded from the Web).
When the content is changed using any of these functions, any
previous content is cleared.
