PdfNavigationStack remembers which destinations the user has visited in a PDF document, and provides the ability to traverse backward and forward.
This property holds the current page that is being viewed. If there is no current page, it holds
Pops the stack, updates the currentPage, currentLocation and currentZoom properties to the most-recently-viewed destination, and then emits the jumped() signal.
Goes back to the page, location and zoom level that was being viewed before back() was called, and then emits the jumped() signal.
If a new destination was pushed since the last time back() was called, the forward() function does nothing, because there is a branch in the timeline which causes the "future" to be lost.
Adds the given destination, consisting of page, location and zoom, to the history of visited locations. If emitJumped is
false, the jumped() signal will not be emitted.
If forwardAvailable is
true, calling this function represents a branch in the timeline which causes the "future" to be lost, and therefore forwardAvailable will change to
Modifies the current destination, consisting of page, location and zoom.
This can be called periodically while the user is manually moving around the document, so that after back() is called, forward() will jump back to the most-recently-viewed destination rather than the destination that was last specified by push().
currentLocationChanged signals will be emitted if the respective properties are actually changed. The jumped signal is not emitted, because this operation represents smooth movement rather than a navigational jump.
