The original use case for this bug is entering an overset inset when
there is a selection. The expected result was to have the selection
pasted in main text, but the result was to have it in the cell.
Insets already have idxFirst() that is able to set cursor to the
"entry" cell of an inset. This patch introduces firstIdx(), which is
the index of this cell and uses it in idxFirst() (idem for
lastIdx/idxLast).
As a consequence, several instances of idxFirst/idxLast can be removed.
Now for the real fix: the two places where the cell in which selection
is inserted seem to be:
* Cursor::macroModeClose
* Cursor::handleNest
These two methods are changed to insert material in the entry cell
instead of cell 0.
idxFirst/Last methods are added to InsetMathRoot and InsetMathStackrel
so that the natural entry point is the nucleus of those insets.
Finallly, a typo is fixed in InsetMathNest::edit() where enter_front
computation was incorrect.
Add a `cancel' boolean to macroModeClose() that just removes all trace
of what has been entered instead of finalizing it.
When entering a macro in mathed, let LFUN_ESCAPE invoke
macroModeClose(true). The new semantics of LFUN_ESCAPE in mathed is
thus to abort the input of a macro name.
Fixes bug #9251.
Basically, everything that does not depend on a BufferView should move
there. Some methods that do not seem to need a BufferView, like
selHandle or IdxFirst or push actually depend on it and could not be
moved.
This allows to simplify a few uses of recordUndo helpers.
- Move some methods to DocIterator: nextMath, prevMath, getPossibleLabel,
getEncoding;
- Move some methods to CursorData: setCursor, setCursorSelectionTo,
(setCursorTo|normal|reset)Anchor, (set|clear)Selection,
sel(|ection)(Begin|End), selectionAsString, info, currentState,
(mark|clear|check)NewWordPosition, fixIfBroken, sanitize, all undo
related methods, reset, isInside, leaveInset, current mode;
- kill some unused methods: macromode, replaceWord, setScreenPos, touch,
markInsert, markErase;
- Move code around to group things, and add a few comments (a lot remains to be done).
This changes lead to some related changes in other classes: removal,
change of parameter.
No intended change.
Now the selection is not done by the inset, but by the MathData
itself. This allows for some code simplification and avoids an
extra redraw.
Additionally, this fixes the selection inside macros, which was broken
by the new MathRow code.
Now backspace and delete in text will select non-empty math and text insets
before deleting them. This is consistent with what happens in math already.
This is implemented for InsetText as well but can be disabled in case of
negative feedback.
This can be set for any sort of inset with the new virtual method
Inset::confirmDeletion.
New option "force" for the LFUN_*_DELETE_* commands, that bypasses the
confirmDeletion check.
Since in InsetMathNest::cursorPos we do not know what is the value of
the row element before value of a given BOX, it does not make sense to
set the cursor at a given offset from the start of the MathData
object.
Therefore here we set the cursor in the middle of the MathData object,
which unfortunately may or may not be visually centered wrt the BOX.
The best solution would be to use the MathRow data here, but
unfortunately this is not completely trivial.

Following discussion on the list:

This defines a new behaviour for Ctrl[+Shift]+Arrow in math:
* Left/Right does not enter insets
* Left/Right jump groups of insets that have the same math class ("words")
* Enable Up/Down for consistency.
This helper method is used to set the inset position cache at drawing
time. However this is already done by the drawing code itself
(MathRow::draw, RowPainter::paintInset), so that there is no need to
do this same work again in a different place.
Note that the inset positions are still set in InsetTabular::draw for
each cell.
This commit comes with a mild risk attached (it might be that some of
these calls were useful after all!), but all of this is fixable.
It should be now possible underlining or striking out any kind
of math inset containing any math construct indigestible to ulem.
While this was already possible for inline math insets, they could
have break if an aligned environment was used, for example.
This is now possible also for diplay math. Even if this can be
nonsensical and not visually perfect, at least no latex errors
should be generated if one tries to.
Showing deleted display math by enabling "Show Changes in Output" was
only possible with dvi (through dvipost). Although LyX strikes out
such formulas on screen, it was impossible obtaining an output
directly using pdflatex (or other engines producing pdf) because
ulem cannot cope with display math material and gives errors.
The solution is to strike out by ourselves such deleted formulas.
I took into account several options. One of them would produce
an output similar to dvipost (which strikes out each element), but
would have required much more changes in the output routines.
Eventually, I opted for using tikz, which gives a more clean
output (as it requires to simply adding a preamble and a postamble
to the latex code of any displayed math, instead of a mark up
tailored to each particular math construct). The look of the pdf
output is similar to the way LyX strikes out the equations on screen.
The main thing it does is integrate mouse-modifiers into the
FuncRequest machinery. Previously, these had to be passed
separately, which led to some ugly function signatures.
There was also an unnecessary form of the constructor, which
can now be removed.
No change of behavior is intended.
The only exceptions are:
- The purpose of the header is to drag in the used symbol, e.g. unique_ptr.h
- The used symbol is inside a class or a namespace other than lyx
The reason for this is that global 'using' statements effectively forbid to
use the used symbols in any other namespace in the whole program, since simply
adding or removing an #include of the corresponding header subtly changes the
name lookup. The namespace lyx is sort of global, so it should not have these
statements either.
Replace the manual manipulation of a stack of RowEntries with a Changer
function. When I introduced the stack of RowEntries, I did not know about the
Changer mechanism.
The old name would be confusing wrt setSelection(), which does additional checks.
This one is a pure acessor, and the more complete methods are
* setSelection(), which avoids empty selections
* clearSelection(), which resets anchor, and sets word selection and mark more to false.
Most of the code should use these two instead of selection(bool), but this is for later.
WriteStream is now built from an otexstream instead of an odocstream, and
therefore counts lines in a TexRow. Calls to TexRow are added in relevant places
in math insets.
This finishes adding line tracking for math in the source panel and for forward
search.
The functions reverseDirectionNeeded() and reverseDirectionNeeded() do
not rely on the Bidi class. The first one is changed into a Cursor
method, and the second one is replaced with explicit code.
We have some math macros that exist only because LyX can display them easily,
but which require user preamble code. These commands should not appear in
autocompletion, they are only there to make the formulas of users who actually
need thgese symbols and know what to put into the preamble more beautiful.
The math icons for the symbol image in the math completer were hardcoded to the
command names. This is wrong for some icons for various reasons, e.g. the case
insensitivity of windows file systems. Therefore we have to use the replacement
list which is also used for the toolbar icons. Bug #3538 is not closed because
of this problem, but IMHO it has nothing to do with this bug, it is a more
general one.
The problem was that the conversion to plain text (which is used as an
intermediate step) requires for some insets a valid buffer pointer, but
insets in the cut stack do not have one. Now we use the same temp buffer
business as for copying to the external clipboard.
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.
