As it was, the comparison buffer was sharing a DocumentClass with
one of the compared buffers. I don't fully understand why this was
causing a problem, since we use a shared_ptr. But this patch creates
a new DocumentClass for the new buffer.
This is preliminary work to make roots look more like in TeX output:
* correct font size for root order
* set minimum size of the root from the max ascent descent of the
font. This is what TeX does.
* fix drawing, and in particular horizontal size.
More needs to be done, in particular:
* handle zooming and dpi correctly by removing hardcoded pixel values.
* factor the code for the two types of roots in one.
With RtL text, the method can be non-monotonic wrt x value (which is a
Qt bug). To work around this, we check whether positions adjacent to
those returned by xToCursor look better. Depending on whether the new
x position is too small or too large, we look backward or forward for
a better solution.
The performance is probably not great, but this is only needed for
user interactions, so the performance penalty should not be a problem.
Fixes#10569.
Coverity flags this code as not handling exception that may happen in buffer().
My own analysis is that this can never happen because isBufferValid()
does check whether buffer_ is null.
Any insght appreciated. The commit should be expeanded to more cases, actually.
The RenderButton object now has this property. It is set depending on
the value of inheritFont() method that is currently only set for
InsetRef, InsetBibtex and InsetCitation.
Fixes bug #10258
There a some exceptions related to the fact that BOOST_ASSERT throws
an unhandled exception, which is fait enough. This is handled by
uploading a modeling file to coverity.
The second batch of issues are related to the use of lexical_cast in
convert.cpp. We use now a wrapper around boost::lexical_cast that does
not throw but return empty strings instead. I am not sure actually of
when lexical_cast could fail.
The special mode used by macros where the macro name is displayed as
grey text in a box is now one of the possible marker types for any
inset. The new code puts the macro name below the text, which means
that only the text below the current line will be moved. This makes
edition much more comfortable. The grey border around the contents has
been removed too.
The marker_type enum has been moved from Inset to InsetMath. A
markerMargin() function returns the horizontal margin required on each
side for the marker. Only the corner-type markers MARKER and MARKER2
need some.
A new BOX_MARKER enum value has been added and is taken care of in
afterMetricsMarkers (renamed from metricsMarkerVertical) and
drawMarkers.
The InsetMath::marker() macro now takes a BufferView pointer as
argument, so that the marker type can depend on editing state.
MathRow::metrics now makes changes to the MathRow object when needed.
The specific metrics/draw code in MathMacro has been removed and
replaced by assertions. Code in addToMathRow and marker is adapted to
reflect the cases where linearization is possible.
Rephrase positively the check box for the output of en- and em-dashes
and disable it when using non-TeX fonts. The state of the check box
is remembered, so that toggling the non-TeX fonts check box does not
cause information loss.
