m_deviceResources->GetD2DDeviceContext() always returns null
I need to render plain text in a Holographic App, My code is based on Holographic Facetracking Sample (https://github.com/Microsoft/Windows-universal-samples/tree/master/Samples/HolographicFaceTracking/cpp) and the DirectX spiningcube UWP Template (SampleFpsTextRenderer class to be precise), the problem is when I try to access to
m_deviceResources->GetD2DDeviceContext();
It always returns null so a npe appears.
In my DevicesResources.h file I have:
// D2D accessors.
ID2D1Factory2* GetD2DFactory() const { return m_d2dFactory.Get(); }
IDWriteFactory2* GetDWriteFactory() const { return m_dwriteFactory.Get(); }
IWICImagingFactory2* GetWicImagingFactory() const { return m_wicFactory.Get(); }
ID2D1DeviceContext1* GetD2DDeviceContext() const { return m_d2dContext.Get(); }
D2D1::Matrix3x2F GetOrientationTransform2D() const { return m_orientationTransform2D; }
// Direct2D factories.
Microsoft::WRL::ComPtr<ID2D1Factory2> m_d2dFactory;
Microsoft::WRL::ComPtr<IDWriteFactory2> m_dwriteFactory;
Microsoft::WRL::ComPtr<IWICImagingFactory2> m_wicFactory;
Microsoft::WRL::ComPtr<ID2D1DeviceContext1> m_d2dContext;
Any idea of what the problem can be?.
PS. Device m_deviceResources is not null, I used breakpoint to check this.
