If an element is underlined in mathed by using the text properties
dialog, the changes accumulate. So, for example, to change a single
underline to a double one, one would need removing the previous
underline first. This commit allows using the text properties
dialog and simply replace an underline type with another one.
However, this works only if the underlined element is not included
in some other inset. For example, given "\uline{\text{abc}}",
selecting the 'b' and choosing a double underline produces
"\uline{\text{a\uuline{b}c}}". But, given "\text{\uline{abc}}", and
operating as before produces "\text{\uline{a}\uuline{b}\uline{c}}".
This change forces metrics computation in all cases when cursor enters
a math inset from above/below, but I do not have a better idea right now.
Fixes bug #12952.
Until now only the color of the text could be changed by using
the text properties dialog. This commit allows changing all
other properties except for strikethrough. It is possible to
also add underlining with the limitation that the changes
accumulate. This requires other work but I think that underlining
and strikethrough are not so important in mathed and can be
refined at a later time.
Fixes#12958
The proper way to do word-wise selection is to compute the words
around both the cursor and the anchor.
Note that code is uglier than it should because CursorData::normalAnchor()
returns a CursorSlice instead of a DocIterator.
Fixes bug #12533.
Some text-in-math environments such as \text, \mbox, \fbox, and
\makebox, inherit the outer text font. This commit reflects this
in the on-screen representation.
Fixes#12950.
This reverts commit d72b9b0238.
Unfortunately, the font taken into account is the font at the
current cursor position rather than the font of the corresponding
math inset.
The text-in-math environments such as \text, \mbox, \fbox, \makebox
and so on, inherit the outer text font. This commit reflects this
in the on-screen representation.
Fixes#12950.
When setting halfline parskip with parskip provided, we still need
to set this explicitly, as we don't know the current \parskip value.
Also improve code readability.
Error handling issues (CHECKED_RETURN)
Calling "translateString" without checking return value
(as is done elsewhere 15 out of 18 times).
AFAICS we do not need the boolean return value in these two cases.
