I am not sure for enable/disable but you can hide those buttons by playing with WindowsFlags. See this example.

which signal trigger when we close window

For a Dialog
void accepted ()
void rejected ()

For Widget
QWidget::closeEvent()

Have you tried using GetSystemMenu and then using EnableMenuItem on the "Close" item ? Theoretically, if you disable the Close menu item, it will disable the close button too.

this->setWindowFlags((
(windowFlags() | Qt::CustomizeWindowHint)
