BufferParams::setDocumentClass() deletes the old document class of the buffer
and creates a copy of the new one. Therefore, the stored layout pointers in
the paragraphs (actually only one paragraph exists) are dangling afterwards.
Resetting them before setting the document class helps here.
In the long term we need to get rid of BufferParams::setDocumentClass()
completely, this is very ugly.
Invoking a computer algebra system program for computing a selected
subformula has never worked (checked with all LyX versions back to 1.3)
and, moreover, in the presence of a selection things go awry.
This commit allows this computation by replacing the selected
subformula with the result of the computation.
A similar fix was reverted (453ce611) because of crashes.
The crashes occurred simply because of a failed check that
we have a buffer view before using it. That is now done in
this commit.
The below commit description is copied from the original
commit (fb05011a):
Empty selections can cause confusing behavior for a few reasons:
(1) some functions behave differently depending on whether there is a
selection. If I press delete, nothing happens (where I expect the
character or inset before the cusor to be deleted). If I toggle bold or
emphasize nothing happens (where if there is no selection the entire
word is toggled). There are other LyX functions that depend on whether
there is a selection or not. Further, I wonder if any part of LyX's code
assumes that if there is a selection it is non-empty.
(2) menu options are incorrectly set. For example, the scissors icon.
For remaining empty selection issues, see #9222.

Our TempFile class uses QTemporaryFile internally, and, on Windows,
this keeps the file locked so that we cannot rename it. So we have
to release the lock.
- the example was designed to follow the style of the other LyX documentation files, e.g. not to insert options as one big TeX-code inset.
- fix some typos
- (I cannot save files with LyX 2.2 atm due to bug #9234)
There are 3 possible actions (in order)
* select current cell
* select all calls of inset
* select the inset from outside (in the containing inset)
This fixes completely #7727.
this module was not usable since the preamble stuff was missing and also almost all options. But many PDF-comment types are quite useless without options.
