visibility

controls how the graphical region is presented. It is set to the value "hidden" to turn off any graphical region that is not to be displayed for the current use of a graphic. Otherwise the value "visible" is assumed, which means that the graphical region will be displayed.
Note
The attribute visibility of the element <grobject> in the graphics companion file has three allowable values:
- "on" - the graphical region can be selected to be visible
- "off" - the graphical region cannot be selected to be visible
- "inherit" - the values "on" and "off" are inherited from the attribute pictureVisibility of the element <webcgm> in the graphics companion file, ie, "on" or "off"
The combination of the values for the attribute visibility of the element <hotspot> and the values for the attribute visibility of the element <grobject> provides the function of whether a graphical region can be selected for display or not. This combination has three allowable definitions:
- visible, not selectable, meaning one of the following:
- Do not define in a hotspot (do nothing).
- Define a hotspot without any internal references, data module references, or CSN references.
- Define a hotspot without any internal references, data module references, or CSN references and set the value of the attribute visibility to "visible".
- visible, selectable, meaning one of the following:
- Define a hotspot with at least one internal reference, data module reference, or CSN reference.
- Define a hotspot with at least one internal reference, data module reference, or CSN reference and set the value of the attribute visibility to "visible".
- not visible, not selectable, meaning:
- Define a hotspot with no internal reference, data module reference, or CSN reference and set the value of the attribute visibility to "hidden".
Note
The use of the definition, not visible, selectable, is disallowed.
