  • [アーティクル]

3/28/2014

This message adds one or more images to the list of button images available for a toolbar.

Syntax

TB_ADDBITMAP wParam = (WPARAM) nButtons; 
    lParam = (LPARAM)(LPTBADDBITMAP) lptbab;

Parameters

  • wParam
    Not used.
  • nButtons
    Number of button images in the bitmap. If lptbab specifies a system-defined bitmap, this parameter is ignored.
  • lptbab
    Long pointer to a TBADDBITMAP structure that contains the identifier of a bitmap resource and the handle to the module instance with the executable file that contains the bitmap resource.

Return Value

The index of the first new image indicates success. -1 indicates failure.

Remarks

The bitmap specified in the lptbab parameter can contain multiple images. The number of images in the bitmap must be specified in the nButtons parameter.

The bitmap width should be nButtons multiplied by the image width, and the bitmap height should be equal to the image height.

The default image width is 16 pixels and the default image height is 15 pixels. The default image width and height can be changed using TB_SETBITMAPSIZE. If the size of the bitmap is not the default or if you have multiple images in a bitmap, you must call TB_SETBITMAPSIZE to change the default size settings.
