Q:

Qt Whats This using a link/anchor

How can I put an anchor <a> into a whatsThis for a widget an intercept it being clicked?
I know about linkActivated in a QLabel, or linkClicked in a QTextBrowser, but I don't know how I can do the same thing with a Whats This text.
To be clear, I want to know if this is possible without interception help events and managing the WhatsThis mechanism on my own.

A:

If I understand your question, it's that you want to know if there is a SIGNAL() for this. There does not appear to be. Seems you have to watch for the QWhatsThisClickedEvent by deriving your own Widget class or with some kind of global filter:

FYI, the actual point where the QWhatsThisClickedEvent is emitted in the Qt sources is here:
