Freehand Hot Spot Tool

Note: This topic is for Document/Medical only.

The freehand hot spot annotation object (ANNOBJECT_FREEHANDHOTSPOT) is an array of points that create a sequence of joined lines. With the automated functions, in design mode, each line segment is formed with a mouse move event when the left button is down, and the object is completed on a mouse up event. In run mode, the object is transparent, but the mouse pointer changes to a hand when it is over the object. Clicking on the button sends a WM_LTANNEVENT message that indicates an activation event.

In design mode, click on the object with the right mouse button to do the following:

• Undo the last user action.

• Cut or copy the object to the clipboard.

• Delete the object.

• Select all objects.

• Lock and unlock annotation objects. See Password Dialog Box for Annotations

• Set and manage hyperlink properties for an object or group of objects. Note: The actual management of a hyperlink must be done through low-level implementation. Only the Menu Item "Hyperlink" and an associated event are provided through the automation object. For more information, refer to Implementing Annotation Hyperlinks.

• Bring the object to the front or send it to the back.

• Add or delete nodes. Add a node by clicking on the spot where you wish to add a node, then select Add Node. To delete a node, click on the node you wish to delete and select Delete Node.

• Change the name. See Name Dialog Box for Annotations.

• Change the line width and style properties. See Line Dialog Box for Annotations.

• Change the fill mode. See Fill Dialog Box for Annotations.

• Change the foreground and background colors. See Color Dialog Box for Annotations.

• Change the font selection and font characteristics. See Font Dialog Box for Annotations.

• Change the ROP2 code. See ROP2 Dialog Box for Annotations
