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?

Accepted Answer

Use the binary negation flag ~

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

So, to remove a customization window hint: -

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