C++ (Cpp) EnumerateSensors Examples

Example #1

File: MainWindow.cpp Project: dcastro9/emory_kinect_project

/// <summary>
/// This method will construct all the member classes and enumerate all the sensors
/// </summary>
void CMainWindow::InitializeResource()
{
    // Set the dialog icon
    NuiViewer::SetIcon(m_hWnd);

    // Set window minimum track size
    m_minTrackWidth = GetWindowSize(m_hWnd).cx;

    // Load url string
    LoadStringW(GetModuleHandle(0), IDS_MOREINFOURL, m_moreInfoLinkUrl, MaxStringChars);

    // Set text font style
    SendMessageW(GetHandle(IDC_CONNECTEDDEVICESTEXT), WM_SETFONT, (WPARAM)LargeTextFont, 0);
    SendMessageW(GetHandle(IDC_REQUIREDSENSORTEXT), WM_SETFONT, (WPARAM)LargeTextFont, 0);
    SendMessageW(GetHandle(IDC_STATUSTEXT), WM_SETFONT, (WPARAM)LargeTextFont, 0);

    // Set the logo picture
    HBITMAP hLogoImage = nullptr;
    EnsureImageLoaded(hLogoImage, IDB_LOGO);
    SendMessageW(GetHandle(IDC_LOGOPICTURE), STM_SETIMAGE, IMAGE_BITMAP, (LPARAM)hLogoImage);

    // Create sensor list instance
    m_pSensorListControl = new SensorListControl(GetHandle(IDC_KINECTSENSORLIST));

    // Create status log list instance
    m_pStatusLogListControl = new StatusLogListControl(GetHandle(IDC_STATUSLOGLIST));

    // Create kinect window manager instance
    m_pKinectWindowMgr = new KinectWindowManager(m_hWnd);

    // Construct all the sensors
    EnumerateSensors();

    // Upate layout and show/hide status
    UpdateLayoutAndShowStatus();
