This requires the introduction of the booleans selected_left and
selected_right in PainterInfo. These tell whether the selection
continues at the left/right of the inset.
This information allows to
1/ paint equation number in the right color: either current text color
or selection text color.
2/ before that, paint a small background rectangle of the correct color.
This allows to avoid painting a large rectangle of an arbitrary color
that was the cause of the bug.
Fixes bug #12319.
It was an error using an absolute size instead of one relative to the
size of the used font. It was requiring using the physical dpi of the
screen and caused #12222. Now everything is computed with respect to
the metrics of the font and should be automatically correct.
Fixes#12222.
The context menu for InsetMathRef is now usable.
InsetMathRef still misses support for RefStyle and thus the
corresponding entries are omitted from the menu. But this would
be a different bug.
It is now possible to get a context menu for math insets.
InsetMathSpace was already providing a specific context menu,
but it was never triggered because the math hull inset is not
descendable. It is still so, but now when a context menu is
requested all the insets inside the math hull are examined.
If the inset under the cursor provides a context menu, it
is shown instead of the general math one.
Fixes#12100.
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.
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.
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.
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.
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.
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
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
It turns out that the code is the same in texted ans mathed and that
whatever is done in InsetTabular is not useful.
This means that we do not need to deal Text::dispatch idiosyncrasies
(in particular forcing the cursor to be visible).
Fix bug #11225.
If a macro has only optionals and none is specified and a [ immediately
follows, we have to terminate the macro with {}, otherwise what follows
is taken to be an optional argument.
Fixes#11665.
The ensuremath math inset derives from InsetMathNest, so that only the
first cell of a grid gets pasted. This patch makes it a fixed 1x1 grid
inset so that pasting works as in normal simple math hulls, i.e., all
cells are pasted, one after the other.
Fixes#11617.
At the moment, there is no support for plurals and capitalization.
A long comment explains why. Support could be added for that without
a format change.
Since we are not sure of where the cursor ends up after invoking
Cursor::handleNest it is safer to reset the cursor at each cell,
rather than reuse the same one over and over.
Related to bug #12035.
- Add limits support to InsetMathScript
- Add limits support to InsetMathClass
- Fix bug where limits changing is disabled in inline math
Now the MathData objects remember whether they are in diaply mode.
Fixes bug #12045.
The problem here is that the check against TEXT_CODE only
catches InsetText, and not its subclasses. Same for the check
against MATH_HULL_CODE. So there is reason not to check codes
here.
This reverts commit 5a54ccfa87.
