ATTR_HELP_CUSTOM_POINTER_IMAGE, MSG_HELP_CONTROL_GET_POINTER_IMAGE
The help controller changes the pointer image when the pointer is over a link in the help text. This is so the user knows where to click and expects a link to be followed. Applications that want custom pointers can set the "link" pointer image with
ATTR_HELP_CUSTOM_POINTER_IMAGE
. This attribute takes an optr to a custom pointer image definition.
The pointer image is a
PointerDef
structure and must be stored in a chunk in a sharable, non-duplicated data block. Note also that to use a custom pointer image, you must explicitly declare a HelpControl object, even for Normal Help.
You can retrieve the link pointer image by sending
MSG_HELP_CONTROL_GET_POINTER_IMAGE
to the HelpControl object. This will return the current image in use, either a custom image or the default. This message is detailed on MSG_HELP_CONTROL_GET_POINTER_IMAGE
.
