How to remove a Qt WindowFlag?

Question

To set the window flags I use setWindowFlags(/* flags */) function.

How can I remove a only one window flag?

Is this possible?

Answer 1

Use the binary negation flag ~

unsigned int flags = flags();
flags = flags & (~FlagEnum);

So, to remove a customization window hint: -

flags = flags & (~Qt::CustomizeWindowHint);
