How to hide close button in QDialog?

Hi,

Just wondering how to hide the close button on a QDialog?

Thanks

By modifying flags set on the widget. Just be aware this will only hide the button, it won't prevent your dialog from being closable.

Thanks.

I looked at the Window Flags Example in Qt Assistant. Unfortunately Qt::SubWindow wasn't included and this was the only flag that hid the close button.

This is what worked in the end, I put it in the dialog constructor.

this->setWindowFlags(Qt::SubWindow);

this->setWindowFlags(Qt::SubWindow);

To copy to clipboard, switch view to plain text mode

No, that's not a good approach. You need to use Qt::CustomizeWindowHint and remove Qt::WindowCloseButtonHint from the hints passed to the window.
