The math color inset inherits the mode of the containing inset.
This mode is inferred by the kind of font in effect. Setting the
right mode allows to insert spaces where these should be allowed.
Another small glitch was that the selection was always parsed in
math mode, so that any space was swallowed, even if the inset would
allow them.
We lack the necessary font (cmb10) for drawing bold uppercase greek
letters. It would be overkill adding it for this sole purpose, so
adopt the same poor man's bold strategy used with \boldsymbol.
Due to the way these decorations are implemented, entering
them with the cursor (either form right or left) required
pressing two times cursor left or right.
Fixes#2264
The bookmarks are shown with circled numbers in the right margin (or
the left margin in RTL mode). A new color "bookmarks" has been added.
Currently bookmark 0 (the return position) is not displayed because it
is very disturbing in practice.
To make this work, a new method BookmarksSection::bookmarksInPar
retuns the list of bookmarks in a paragraph along with their position.
Force redraw when using bookmark-save and bookmark-clear.
Caveats:
- this solution does not show the precise position of the bookmark
(this is supposedly not a problem).
- if several bookmarks are on the same row, they will currently be
garbled. It would be easy to make sure that only one is shown ; what
would be more difficult would be to move the second bookmark lower.
- it is possible to make sure that the markers are correctly centered
in the margin, and that the margin size is large enough to hold the
marker (I did not try all fonts).
Fixes bug #2496.
Add code stolen from QBitTorrent that enables properly HiDpi handling.
HighDpi support is set by default starting with Qt 5.6.
Support for fractional scaling is added for Qt >= 5.14.
Hopefully fixes bug #12060.
When invoking inset-dissolve with the cursor in front of the inset,
add recordUndo call to make sure that the cursor is at the right
class.
Fixes bug #12164.
A new method for drawing ellipses has been added to the painter
and used for drawing real dots for math decorations and the various
\cdots, \ddots, \vdots, etc., latex commands.
Full GCC output is:

In the row painter, when painting a centered label, one wants to get
the left/right margin of the non-first rows (without indent). It was a
bad idea to change leftMargin(pit) to do that, because its semantics
are unclear and the the code depends on the fact that this function does
strange things when the paragraph is empty...
Fixes bug #12118.
Introduce a new Row::contents_dim(), which height is restricted to the
row contents and does not contain any extra vertical spacing.
Rely on this for painting selections: if the selection starts on row,
for example, the ascent of the contents dim is considered. If ot was
started above, then the full dim is used.
Fixes bug #3899.
Keep from 907f0207 the introduction of BufferView::top/bottomMargin()
and the setting of the top/bottom margin of the document. The
difference is that the extra height is still added to the relevant
rows, and not only to the paragraph metrics.
Keep from f41ca959 the reduction of top/bottom margin for Adv F&R
workareas.
For now, the simplest thing to do it to compute metrics in all cases
before calling setCurrentFont().
In 2.5, a better approach will be to add a new virtual function
InsetText::setFont that will set correctly TextMetrics::font_ (a cache
of the reference font).
Fixes bug #12126.
For math decorations with arrows at both ends the code was simply
stretching a prototype symbol, thus distorting the arrows.
Another drawing mode is introduced allowing to draw an element by
maintaining its aspect ratio also when it has to be drawn at the
other end of a decoration. An element drawn using this mode is simply
shifted to the other side by adding either the width or the height,
and a finer adjustment can be obtained by specifying an additional
horizontal or vertical shift.
Language settings will be ignored if
a.) User selects if with setIgnoreFormat("language", true, true)
or
b.) The pattern does not contain lang-specs other than the default language of document
or
c.) The pattern contains math parts
When the argument is long enough, the arrow in the on-screen representation
was not covering the first or the last glyphs. For example, using
\overrightarrow{abcdefghijklmnopqrstuvwxyz}
the 'a' was drawn outside the covering arrow.
Just recompute metrics instead of triggering a full redraw. The old
behavior was that, when the document was less that one page long, the
cursor would blink to the top of the document before going to its
correct position.
When the cursor is at the top, it is important to make sure that, not
only its row is visible, but also the extra margin at the beginning of
the document, that was added at 907f0207.
Fixes part of bug #12123.
Now that the ascent of the paragraph metrics is not necessarily the
ascent of the first row (see 907f0207), the test is too strict. Now it
is more symmetrical wrt the !up case.
Note that changing this part of code is associated with a
non-negligible risk of creating a bug elsewhere.
Fixes part of bug #12123.
This stores its argument, the currently selected text or the word under
cursor in the search cache that is used by word-find[-backward|-forward]
if no argument is given to those.
Prerequisite for a feature apparently expected on the Mac.
This commit takes into account also the case in which a prime follows
a superscript, a case not explicitly mentioned in bug 1633.
This case has to be accounted for in a different way. We cannot look
ahead when exporting, so we simply tell TeXMathStream to output an
empty group if we just output a superscript and a prime comes next.
Some lfuns are handled directly in GuiApplication while handling
of menu hiding in fullscreen was done on the level of GuiView.
We'll see if this code movement breaks in different scenarios,
but quick grep suggested that the only other way to guiview
dispatch is through drag&drop when menu isn't involved.
Add a new ForceAll update flag that forces to update metrics and
redraw all buffer views.
The situation in multi windows setting is very fragile and will need
to be adressed properly in the 2.5 cycle.
This patch takes into account the skewness of a character for properly
align a decoration. Unfortunately, the required amount of shift depends
on single chars, so that the recently introduced FontMetrics::italicSlope()
method cannot be used with all characters. A heuristics that produces
satisfactory results is using the italic slope only with characters whose
italic correction (kerning) is zero.
Part of #11491
Using unordered_map instead of map.
Reasons:
1.) The relevant maps contain 166(Keys) and 649(Accents) entries.
This mean that average access with 'map' needs 8 to 10 compares to find the value.
2.) Since we are using at least c++11, the unordered_map is available
2.) increasing the maps (in future) needs not to be considered anymore, because
the access-time will not increase.
When hitting backspace in the first position of a cell in mathed,
if the cell is part of an array, the whole array is dissolved
and the sole cell content pasted in the containing environment.
But if the cell is part of an eqnarray or align math hull type, the
cursor is simply (and unexpectedly) taken out of the whole equation,
which is left unchanged.
This patch makes backspace equivalent to the cursor left key in those
cases, while leaving the behavior unchanged in all other ones.
Fixes#11678
A reference can be directly inserted into mathed but cannot be pasted
because the pasted material is returned in plain text format. This patch
allows getting a string from the cut stack in a suitable format allowing
the math parser to actually create an InsetRef.
Fixes#11539
In Qt 5.15 many deprecation warnings are issued, presumably for
helping the port to Qt 6. They are really a load but can be
shuten up by using -DQT_NO_DEPRECATED_WARNINGS, except for the ones
about MidButton, AdjustToMinimumContentsLength, and DefaultLocaleLongDate.
This change should not affect compilation with Qt 4, as all changes are
backward compatible (only Qt versions prior 4.5 could be affected).
Following 4a4ded22, the enabling of some change-related functions is
handled in updateBuffer. However, this method is not ran at every
document change for performance reasons.
This patch adds code to every place that modifies
Paragraph::Private::changes_ that checks whether the `changedness' of
the paragraph, err... changes.
To this end, a new helper struct is introduced that remembers
paragraph state at contruction time, and compares it to new state in
the destructor.
New forceUpdate/needUpdate methods are added to Buffer class, since
the cursor is in general not available in the places where these
changes are made.
Fixes bug #12074.
