> I don't understand why CrontabWidget d-tor is called
here a CrontabPrinter is create, and a CrontabWidget is passed to the c-tor
void CrontabWidget::print()
{
CrontabPrinter printer(this);
and named mCrontabWidget
CrontabPrinter::CrontabPrinter(CrontabWidget *crontabWidget)
: mCrontabWidget(crontabWidget)
then (crontabPrinter.cpp:60)
printDialog->setOptionTabs(QList() << mCrontabWidget);
probably when the printDialog d-tor is called (crontabPrinter.cpp:64),
mCrontabWidget d-tor is called
