|
|
* @short PageView object devoted to annotation creation/handling.
|
|
*
|
|
* PageViewAnnotator is the kpdf class used for visually creating annotations.
|
|
* It uses internal 'engines' for interacting with user events and attaches
|
|
* the newly created annotation to the document when the creation is complete.
|
|
* In the meanwhile all PageView events (actually mouse/paint ones) are routed
|
|
* to this class that performs a rough visual representation of what the
|
|
* annotation will become when finished.
|
|
*
|
|
* "data/tools.xml" is the file that contains Annotations/Engine association
|
|
* for the items placed in the toolbar. The XML is parsed (1) when populating
|
|
* the toolbar and (2)after selecting a toolbar item, in which case an Ann is
|
|
* initialized with the values in the XML and an engine is created to handle
|
|
* that annotation.
