Hi,
I have submitted a patch for review:
https://gerrit.libreoffice.org/1657
To pull it, you can do:
git pull ssh://gerrit.libreoffice.org:29418/core refs/changes/57/1657/1
split out the ComboBox code that determines the positioning of subwidgets
and re-use it to get a better calculation of the optimal size of a
widget, rather than taking the current position of the subedit
the upshot of this is that with CTL and/or CJK mode enabled in...
a) calc, then the format->cells font dialog doesn't have squashed font size and
font style listboxes
b) writer, the 10.5 default size for CJK doesn't have part of the .5 clipped
off it
the calcComboBoxDropDownComponentBounds code should be entirely equivalent
to the existing ::Resize calculation given the same input, we just call
it with effectively unbounded available size in the GetOptimalSize case
to find the desired margins around the subedit field
(cherry picked from commit d19eab221f168aed12249ffc8a36a9f1aca5a94e)
