Remarks

Note

To use this message, you must provide a manifest specifying Comclt32.dll version 6.0. For more information on manifests, see Enabling Visual Styles.

The image list referred to in the himl member of the BUTTON_IMAGELIST structure should contain either a single image to be used for all states or individual images for each state. The following states are defined in vssym32.h.

enum PUSHBUTTONSTATES {
    PBS_NORMAL = 1,
    PBS_HOT = 2,
    PBS_PRESSED = 3,
    PBS_DISABLED = 4,
    PBS_DEFAULTED = 5,
    PBS_STYLUSHOT = 6,
};

Note that PBS_STYLUSHOT is used only on tablet computers.

Each value is an index to the appropriate image in the image list. If only one image is present, it is used for all states. If the image list contains more than one image, each index corresponds to one state of the button. If an image is not provided for each state, nothing is drawn for those states without images.
