How to copy a form class

IknowQT

wCellTypeInfo* temp = new wCellTypeInfo(m_pModelInfo, m_pParentWidget);
	wSetupBaseBckg dlg(temp, m_pParentWidget);
	{
		m_pCellTypeInfo = temp;

		if (dlg.DlgResult() == CollectEnums::MeasureMode_Settings::Apply)
		{
			/*wPhotoMetric_Settings* w = qobject_cast<wPhotoMetric_Settings*>(dlg.GetWidget());
			if (w->IsChanged())
				UpdateMesureInfo();

			this->m_pChart->EnableMarkers(m_pPhometricInfo->bPVDisplay);*/
		}

When exiting the function, the wCellTypeInfo* temp variable is destroyed.
Although it was copied with the assignment operator before being destroyed, the copied class is also destroyed because temp itself is destroyed. Is there any way to copy the form class itself?

I made a deepcopy, but it doesn't copy the information in the UI

void wCellTypeInfo::DeepCopy(const wCellTypeInfo* copy)
{
	ui					= copy->ui;
	m_nChkCnt			= copy->m_nChkCnt;
	m_pModelInfo		= copy->m_pModelInfo;
	m_nSeletedCell		= copy->m_nSeletedCell;
	m_pBtnGroup			= copy->m_pBtnGroup;
	//m_pParentWidget		= copy.m_pParentWidget;
}

Maybe because wSetupBaseBckg deletes it in it's dtor.
Simply create a new instance of temp if you need another one.

Where is it destroyed?
I don't see any delete in the code you posted.

You can't copy QObject based classes in Qt. The only thing you can copy is the pointer, but then it is NOT a deep copy...

Thanks for the reply. I'll have to think about if there is another way.
