how to distroy child window which parents is zero, when exiting from application.
If parent is 0, the new widget becomes a window. then how to distroy explicitly?

in the following examples, how to distroy uartDetachedWidget ?
void UartTab::detachWindow()
{
uartDetachedWidget = new UartWidget(0,m_uartNo, true);
uartDetachedWidget->show();
}

Set attribute Qt::WA_DeleteOnClose or store it as a member variable and delete manually in the destructor.

class UartTab
{
// all others members here

private:
QWidget *uartDetachedWidget ;
}

UartTab::~UartTab()
{
delete uartDetachedWidget;
}

following code not working, means not closing the window.

UartTab::~UartTab()
{
delete uartDetachedWidget;
}
