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.
This is a variant of Input for layout files that only searches build
and system directories and thus allows "InputGlobal name.inc" in a user
file name.inc that attempts to modify its global counterpart.
In case of search with format:
If the pattern contains language spec different to the document language
then do not ignore language setting.
Also renamed 'matchstart' in FindAndReplaceOptions to 'matchAtStart'
- Multicolumn now supports multiple paragraphs in non-fixed-width context.
- Multicolumn now supports valign in non-fixed-width context.
- varwidth columns now properly align horizontally and vertically.
Since commit c600906d92 all matches are match-results of examined strings starting
with a character of the same cursor depth, we can be sure to match the same string again if:
1.) the number of characters to the end of the examined strings match.
2.) the match-lengths are identical
The include inset has its own button_ object, that hides the button_
object of the InsetCommand parent. Remove that.
Remove the hand-made caching that uses the set_label_ boolean.
Let metrics() and draw() use the inherited methods. This requires to
use setBroken as needed and to implement inheritFont.
The use of InsetCommand::draw is what restores the hover effect.
Fixes bug #10415.
Set colors now apply to the active mode only. Matching reversed colors
are produced for the other mode if no color is assigned yet.
File format change.
1) Take care of different input if changed the search-mode (with/without format)
This amends ec387b6d
2) Make the braces used in text to be treated as single characters
e.g. transform '\braceleft' to some unicode value
3) Try to use '$' as 'end of sequence' in regex
We have to remove '}' and '\n' chars from the examined string
