Is there a way to know if a user had clicked a KRichTextWidget widget? There is no clicked() signal and using a mousePressedEvent will apply to the entire window.

I could use a mousePressedEvent anyway and filter out all the irrelevant clicks, but is there anything more efficient?

Thank you

In this case, what are you trying to do?

I'm using KRichTextWidget in way that if a user wants to enter some data into it, it expands to a larger size.

By default it is a one line textbox, if the user clicks it, the widget resizes to a larger size.

I suggest asking on the kde-devel@kde.org mailing list regarding this. Not sure if this is possible however, things like this are usually done by adjusting size hints.
