    This function gets the current attribute settings of the GUI window.

    Declaration:

     
    Copy Code
    AT_ERRCOUNT ACCUAPI IG_GUI_window_attribute_get(
            HWND hWnd, 
            AT_MODE nAttributeID, 
            LPVOID lpData
    );
    

    Arguments:

    Name Type Description
    hWnd HWND Handle of the window in which the image is displayed.
    nAttributeID AT_MODE A variable of type AT_MODE, such as IG_GUI_WINDOW_PAINT.
    lpData LPVOID A VOID pointer to a variable of the type required by the nAttributeID parameter. This sets the value for the attribute defined by nAttributeID.

    Return Value:

    Returns the number of ImageGear errors that occurred during this function call.

    Supported Raster Image Formats:

    This function does not process image pixels.

    Sample:

    None

    Example:

     
    Copy Code
    HWND hWndImage;
    AT_ERRCOUNT nErrcount;
    AT_MODE         nAttribute;
    BOOL bPaintFlag;
    bPaintFlag = TRUE;      /* enable painting */
    /* Get the current attribute settings of the GUI window */
    nErrcount = IG_GUI_window_attribute_get(hWndImage, IG_GUI_WINDOW_PAINT, &bPaintFlag);
    

    Remarks:

    If the argument nAttributeID is set to IG_GUI_WINDOW_PAINT and lpData is set to TRUE, the GUI window is painted.

    There is currently just one attribute, IG_GUI_WINDOW_PAINT, but this may be expanded in the future.
