WhatsThis button in QMainWindow

[_Jack_]

Dear Qt programmers,
a QDialog show a default WhatsThis help button [?] , near the close button, but QMainWindow not. Is there an easy way to have also in a QMainWindow the [?] button near the default close ,reduce to icon and maximize buttons?

Thanks in advance.

See Qt::WindowContextHelpButtonHint.

Hi Lykurg, I know, but the question was: is possible to have together a Qt::WindowContextHelpButtonHint and a Qt::WindowMinMaxButtonsHint ?
It seem they are mutually exclusive...as the examples\widgets\windowsflags also show to me. (I'm using win 7 env). I have to suppose it is not possible to do?

Is it really not possible to have together Qt::WindowContextHelpButtonHint and a Qt::WindowMinMaxButtonsHint ?

Hi, you can OR them together:

setWindowFlags (Qt::WindowContextHelpButtonHint | Qt::WindowMinMaxButtonsHint)

setWindowFlags (Qt::WindowContextHelpButtonHint | Qt::WindowMinMaxButtonsHint)

In theory yes, but the "?" in not shown in reality.

Ah, I wasn't sure whether windows would show it or not.

yes, I do not know under other platforms, but under Windows not works... a bug or an intended feature?

do other windows apps show it because I've never recalled seeing them in the main app? Seems like a limitation in windows maybe
