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
