Enable or disable hyperlink support.
[read/write property] enableHyperlinks([out, retval] VARIANT_BOOL *on) enableHyperlinks([in] VARIANT_BOOL on)
By default, if the user clicks on a hyperlink in a PDF file, the XpdfViewer library will follow the link. This can involve moving to a different page, opening another PDF file, or starting up a web browser. This behavior can be disabled by setting the enableHyperlinks to false.

Note that the link click event (see linkClick) will be called even when hyperlinks are disabled.

viewer.enableHyperlinks = False
