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.
We currently don't have *any* unit-tests for `LinkAnnotation`s, so it seemed a good idea to add a few. These tests are taken from various actual PDF files.
- Add support for the 'NewWindow' property.
- Ensure that destinations are applied to the *remote* document, instead of the current one.
- Handle the `F` entry being a standard string, instead of a dictionary.
This patch also adds/improves utility functions for checking if the passwords are correct/incorrect, and replaces `string2binary` with `stringToBytes`. Finally the patch does away with the `DictMock`, in favour of using actual `Dict`s.
Re: issue 6905.
Using `new {Name,Cmd}` should be avoided, since it creates a new object on *every* call, whereas `{Name,Cmd}.get` uses caches to only create *one* object regardless of how many times they are called.
Most of these are found in the unit-tests, where increased memory usage probably doesn't matter very much. But it still seems good to get rid of those cases, since no part of the codebase ought to advertise that usage.
Given the small size of the patch, I'm also tweaking a few comments and class names.
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.)
