This partially reverts commit 0f1fdaaa9, but only redraws the current
row when the value returns by getPos is obviously false. It would also
be possible to check whether the current cursor has all its insets in
cache instead.
A better fix should be found, but this is unfortunately not 2.2 stuff.
Fixes bugs #9796 and #9812.
These features are active in DEVEL_VERSION when Debug is set to LATEX.
1. The TexRow information is prepended to the source panel.
2. Clicking on any line in the source triggers reverse search. (This would be an
interesting feature to implement on the user side, but we need a proper LFUN.)
[This commit is the output of the "horizontal scrolling" GSoC 2013
project, by Hashini Senaratne. The code has been cleaned up, some
variables have been renamed and moved from the Cursor class to
BufferView::Private. This is the base from which I (jmarc) will polish
the feature for landing on master.
Below is the original commit log of Hashini, updated to reflect the
changes that have been done.]
This feature also applicable for other insets; graphics and labels.
This implementation is capable of scrolling a single row when reaching
its content which is beyond the screen limits, using left and right
arrow keys.
The attribute 'horiz_scroll_offset_' introduced in the
BufferView::Private class plays a main role in horizontal scrolling of
the wide rows that grow beyond the screen limits. This attribute
represents by how much pixels the current row that the text cursor
lies in should be get scrolled.
The main logic that is responsible for drawing the scrolled rows is
within the BufferView class, BufferView::checkCursorScrollOffset.
* The main logic is called via BufferView::draw.
* What this does is set the horiz_scroll_offset_ attribute in in order to
show the position that the text cursor lies in.
* To make sure that BufferView::draw gets involved when Update flag is
FitCursor, necessary changes are made in BufferView::processUpdateFlags.
Basically what the logic that used to set the horiz_scroll_offset_
does is,
* The row which the text cursor lies in is identified by a
CursorSlice that points to the beginning of the row. This is the
'rowSlice' variable used in BufferView::checkCursorScrollOffset. Acessors
are added to obtain this variable. Here row objects were not used to
identify the current row, because it appears that row objects can
disappear when doing a decoration update for example. This means that
comparing row pointers is not a good idea, because they can change
without notice.
* Stop calculations of horiz_scroll_offset_ variable, if metrics have not been
computed yet. Otherwise the calls to TextMetrics::parMetrics, calls
redoParagraph and may change the row heigths. Therefore vertical scrolling
feature may get disturbed. This is avoided.
* Using BufferView::::setCurrentRowSlice resets horiz_scroll_offset_
when changing cursor row. This is done in order to prevent unwanted
scrolling that happens when changing the selected row using up and
down arrow keys.
* Recompute inset positions before checking scoll offset of the row, by
painting the row insets with drawing disabled. This is done because the
position of insets is computed within the drawing procedure.
* Current x position of the text cursor is compared with the
horiz_scroll_offset_ value and the other variables like row.width(),
bv.workWidth(). Compute the new horiz_scroll_offset_ value in order
to show where the text cursor lies in. The basics conditions that we
check before recomputing it are, if the text cursor lies rightward to
the current right screen boundary, if the text cursor lies leftward
to the current left screen boundary, if the text cursor lies within
screen boundaries but the length of the row is less than the left
boundary of the screen (this happens when we delete some content of
the row using delete key or backspace key).
* Change update strategy when scrooll offset has changed. This allows to
redraw the row when no drawing was scheduled. By doing so, it was
possible to redraw a wide row when moving to the leftmost position of the
wide row, from the leftmost position of the row below, using the left
arrow key.
In TextMetrics::drawParagraph it is checked whether the current row is
what is drawing now. If it is so, the value used to the x value of the row
for drawing is adapted according to BufferView::horizScrollOffset.
The method used to pass boundary() was fixed to get row when cursor was in
a nested inset. This matter is considered in Cursor::textRow and it is
modified accordingly.
GuiWorkArea::Private::showCursor() is modified to show the cursor position
in a scrolled row.

The problem here is that the copy_params() routine in FindAndReplace.cpp
created a new DocumentClass, but it never updated its Buffer to reflect
that new DocumentClass. So its Paragraphs still contained points to the
Layouts in the old DocumentClass which, since ead697d4b6, gets garbage
collected once it is no longer needed. So the Layout doesn't exist, and
we crash.
objects. The problem that led to the leak is that these objects can be held in
memory long after the Buffer that created them is gone, mostly due to their
use in the CutStack. So they were previously held in a storage facility, the
DocumentClassBundle. Unfortunately, they were now being created too often,
especially by cloning. It's not really a leak, because they're accessible, but
we weren't ever destroying them.
This new approach uses a shared_ptr instead.
Thanks to Vincent for pointing out const_pointer_cast.
When updating the screen, moving the mouse, or scrolling the buffer, we check whether the hovering status of the insets.

Split LyXFunc::dispatch into a wrapper that does the actual screen updates and
a worker method that updates a DispatchResult object.

* I transferred local function loadLayoutFile() in LyXFunc.cpp to a LayoutFileList::load().
Richard, as I am not into this layout thing, please check that these LFUNs still operate correctly (except from an embedded work area of course).

This patch enhances the Buffer::dispatch() method to make it a full-fledged
member of the dispatch sequence. The most immediate payoff is that LFUNs that
are handled in Buffer::dispatch() can be used from the command line.
We make better use of the DispatchResult object and return error information
through it, rather than using return values. (This was JMarc's suggestion.) We
also introduce a corresponding Buffer::getStatus() method, and modify
BufferView::getStatus() to return a flag indicating whether a decision has been
made, as is already done in some other cases.
Finally, some LFUNs are moved to Buffer::dispatch(), including LFUN_BUFFER_PRINT.

- showCursor(DocIterator): new DocIterator argument.
- showCursor(): use above method.
- scrollDocView(): take care of top and bottom special cases early in the method.

* ParagraphMetrics::computeRowSignature(): Integrate row's dimensions and selection status in the row signature.
* TextMetrics::drawParagraph(): compute the row signature here and rely on that to decide if a redraw is needed or not.
* BufferView::Private: get rid of the ViewMetricsInfo member. Just keep the ScreenUpdateStrategy.
* BufferView::draw(): full screen update even for singlePar case because the row signature will detect if something needs to be redrawn.

The problem was that offset_ref_ was calculated based on an empty metrics. The solution is delay the calculation up until the next metrics update.
* BufferView:
- center(): now just set the anchor_ref and program a new screen recentering.
- updateOffsetRef(): update the offset_ref_

* Buffer:
- get rid of cursor_ and anchor_
- ~Buffer(): update the labels of its master buffer before closing
- closing(): pass the Buffer address.
* BufferView():
- BufferView(): needs a valid Buffer (should be const in the future.
- most of the change is about removing all test of buffer_ nullity.
- resize(): deleted.
- setBuffer(): deleted.
* Application:
- newLyXView(): simplification
- updated design description in Application.h
* Gui/GuiImplementation: remove all WorkAreas and BufferView creation/Deletion. Workareas are directly handled by LyXView/GuiView and BufferView is created/delete by WorkArea.
* LyXView/GuiView: implement the new design
What is not working yet:
- the close tab button: it is implemented but does not show up.

* Layout.h:
- name_, obsoleted_by_, depends_on_ are now docstrings.
All other changes results from the above string -> docstring changes. In particular, we now try to translate the layout names only if possible (i.e. if they are ASCII only).

* buffer_funcs.{h,cpp}: new checkAndLoadLyXFile() transferred from BufferView::loadLyXFile().
* BufferView::loadLyXFile(): deleted.
* LyXView::loadLyXFile(): simplify logic and fix some issues:
- buggy child document leads to crash due to error list dialog.
- ensure that we switch to buffer if there's some errors.
- use LyXView::setBuffer() instead of repeating code.

Fix Bug 3860: Toc crash when loading a child documents.
* BufferView::loadLyXFile(): simplify, transfer last part to
LyXView::loadLyXFile().
Change return value to Buffer created by load (or 0 if none).
Ultimately, this should all be moved to buffer_funcs.cpp, as it is no
longer needed here.
* Buffer::setParentName(): small fix to avoid recursive includes.
* LyXView:
- setBuffer(): properly update the labels and the Toc if this is [LOAD Child
Document] command. Move buffer connection and disconnection, simplifying
earlier code.
- loadLyXFile(): get some code from BufferView::loadLyXFile() and from
LyXFunc::LFUN_BUFFER_CHILD_OPEN, properly handle the child document case.
There's a lot of overlap with setBuffer() here. This needs cleaning.
* LyXFunc: add optional argument to LFUN_BUFFER_CHILD_OPEN to indicate if
the document is being opened by LyX itself rather than the user (as on
View>DVI, for example).
* LyX: adapt to loadLyXFile() API changes.
* insets/InsetInclude: use LFUN_BUFFER_CHILD_OPEN rather than calling
loadLyXFile() directly. Make use of new optional argument.
With this in place, the only thing missing for proper multipart document support is to automatically update the parent Buffer when switching from the parent Buffer. This would be very useful when you work with multiple document sharing the same child documents (as I often do).

for translating keystrokes. Up until now, the switching was done in advance
in all kinds of situations, but not just before translating was actually done
--- which resulted in the KeyMap not always being switched on time...
