C++ (Cpp) GetVisualParent Examples

Example #1

File: XTPMarkupUIElement.cpp Project: killbug2004/ghost2013

void CXTPMarkupUIElement::InvalidateMeasureOverride(CXTPMarkupDrawingContext* pDC)
{
	if (!m_bMeasureInProgress && !m_bNeverMeasured)
	{
		m_bMeasureDirty = TRUE;
		m_bArrangeDirty = TRUE;

		CSize sz = GetDesiredSize();

		Measure(pDC, m_szPreviousAvailableSize);

		if (sz != GetDesiredSize())
		{
			m_bMeasureDirty = TRUE;
			m_bArrangeDirty = TRUE;

			CXTPMarkupUIElement* pParent = MARKUP_DYNAMICCAST(CXTPMarkupUIElement, GetVisualParent());
			if (pParent)
			{
				pParent->InvalidateMeasureOverride(pDC);
			}
			else if (m_pMarkupContext)
			{
				m_pMarkupContext->OnInvalidateArrange(this);
			}
		}
		else
		{
			Arrange(m_rcFinalRect);
			InvalidateVisual();
		}
	}
}

Example #2

File: control.cpp Project: snorp/moon

void
Control::SetVisualParent (UIElement *visual_parent)
{
    if (GetVisualParent () != visual_parent) {
        FrameworkElement::SetVisualParent (visual_parent);
        providers.isenabled->SetDataSource (GetLogicalParent ());
    }
}

Example #3

{
	if (args->GetProperty ()->GetOwnerType() != Type::CANVAS) {

			InvalidateArrange ();
		}
	}
	NotifyListenersOfPropertyChange (args, error);
