CImageList::Create

  • Article

Initializes an image list and attaches it to a CImageList Class object.

BOOL Create(
   int cx,
   int cy,
   UINT nFlags,
   int nInitial,
   int nGrow 
);
BOOL Create(
   UINT nBitmapID,
   int cx,
   int nGrow,
   COLORREF crMask 
);
BOOL Create(
   LPCTSTR lpszBitmapID,
   int cx,
   int nGrow,
   COLORREF crMask 
);
BOOL Create(
   CImageList& imagelist1,
   int nImage1,
   CImageList& imagelist2,
   int nImage2,
   int dx,
   int dy 
);
BOOL Create(
   CImageList* pImageList 
);

Parameters

  • cx
    Dimensions of each image, in pixels.

  • cy
    Dimensions of each image, in pixels.

  • nFlags
    Specifies the type of image list to create. This parameter can be a combination of the following values, but it can include only one of the ILC_COLOR values.

    Value

    Meaning

    ILC_COLOR

    Use the default behavior if none of the other ILC_COLOR* flags is specified. Typically, the default is ILC_COLOR4; but for older display drivers, the default is ILC_COLORDDB.

    ILC_COLOR4

    Use a 4-bit (16 color) device-independent bitmap (DIB) section as the bitmap for the image list.

    ILC_COLOR8

    Use an 8-bit DIB section. The colors used for the color table are the same colors as the halftone palette.

    ILC_COLOR16

    Use a 16-bit (32/64k color) DIB section.

    ILC_COLOR24

    Use a 24-bit DIB section.

    ILC_COLOR32

    Use a 32-bit DIB section.

    ILC_COLORDDB

    Use a device-dependent bitmap.

    ILC_MASK

    Uses a mask. The image list contains two bitmaps, one of which is a monochrome bitmap used as a mask. If this value is not included, the image list contains only one bitmap. See Drawing Images from an Image List for additional information on masked images.

  • nInitial
    Number of images that the image list initially contains.

  • nGrow
    Number of images by which the image list can grow when the system needs to resize the list to make room for new images. This parameter represents the number of new images the resized image list can contain.

  • nBitmapID
    Resource IDs of the bitmap to be associated with the image list.

  • crMask
    Color used to generate a mask. Each pixel of this color in the specified bitmap is changed to black, and the corresponding bit in the mask is set to one.

  • lpszBitmapID
    A string containing the resource IDs of the images.

  • imagelist1
    A reference to a CImageList object.

  • nImage1
    Index of the first existing image.

  • imagelist2
    A reference to a CImageList object.

  • nImage2
    Index of the second existing image.

  • dx
    Offset of the x-axis of the second image in relationship to the first image, in pixels.

  • dy
    Offset of the y-axis of the second image in relationship to the first image, in pixels.

  • pImageList
    A pointer to a CImageList object.

Return Value

Nonzero if successful; otherwise 0.

Remarks

You construct a CImageList in two steps. First, call the constructor and then call Create, which creates the image list and attaches it to the CImageListobject.

Example

m_myImageList.Create(32, 32, ILC_COLOR8, 0, 4);
