Button Annotation Object
(Document and Medical Imaging toolkits)
The Button annotation object (ANNOBJECT_BUTTON) is an image of a standard Windows button that can be activated. With the automated functions, the user clicks and drags to specify the rectangle in the current window. A dialog box then lets the user enter the text for the Button. In run mode, clicking on the Button sends a WM_LTANNEVENT message that indicates an activation event.
For information on flipping, reversing or rotating annotation objects, refer to Flipping, Reversing and Rotating Annotation Objects.
