These have been found using `gulp lint` in combination with the `unused:
true` parameter for JSHint. Unfortunately there are too many false
positives to enable this feature, but now that most globals have been
removed because of the conversion to UMD the results are much more
useful than before.
We're already, since quite some time, using the standard Fullscreen API provided that it's available in the browser. The warning is only caused by the code that checks if the Fullscreen API is supported.
This patch uses a simple preprocessor tag to avoid the warning, since I'm assuming that in general, we want to try and remain backwards compatible with the prefixed versions of the Fullscreen API.
Fixes 7270.
Furthermore we introduce two new methods named `setCallback` and
`setReason` so external code does not change the properties of the class
directly. Finally we update various names of properties and methods to
be more self-explanatory.
With the recent PR 7172, which made the viewer modular, there's now a couple of modules that are no longer easily accessible (e.g. through the console).
This can make testing/debugging more difficult, and means that e.g. https://github.com/mozilla/pdf.js/wiki/Debugging-PDF.js#enabling no longer works in the generic viewer.
For now, as a simple solution, this patch just exposes those non-classes on `PDFViewerApplication` to ensure that they are available, and to avoid polluting the `window` scope.
Persist the state of content sidebar while browsing away from viewer and
initializing the same on returning back to the viewer. The state is saved
in persistent store preferences and used upon viewer initialization.
Fixes#6935
We cannot piggy-back on the `updateviewarea` event in order to update the stored sidebar state, since there're a number of cases where opening/switching the sidebar view won't fire a `updateviewarea` event.
Note that `updateviewarea` only fires when the position changes in the *viewer*, which means that it won't fire if e.g. the viewer is narrow, such that the sidebar overlays the document transparently; or when switching views, without the document position also changing.
This patch also moves the handling of `forceOpen` parameter in `PDFSidebar_switchView`, to prevent triggering back-to-back rendering and dispatching of events.
This is a regression from PR 7097.
(Also, out of scope for this PR, but I think that a `setTimeout` value of `1000 ms` is too large. Switching from scrolling to zooming can fell sluggish, and give the impression that nothing happens.)
