* LyXText - bv(), bv_owner, : deleted. - These methods now need a (Buffer const &) argument: getFont(), applyOuterFont(), getLayoutFont(), getLabelFont(), setCharFont(), setLayout(), singleWidth(), leftMargin(), rightMargin(), computeRowMetrics(), isMainText(), spacing(), isRTL(), cursorX(), rowBreakPoint(), setRowWidth(), labelFill(), labelEnd(). - These methods now need a (BufferView const &) argument and are propably candidates for future removal when 1.6 is opened for development: redoParagraph(), x2pos(), getRowNearY(), getColumnNearX(), checkInsetHit(), setHeightOfRow(). - recUndo(): now need a LCursor argument. * CoordCache::get(LyXText const *, pit_type): - now const. - use const_iterator instead of iterator. * FontIterator: - add (Buffer const &) argument to ctor - buffer_: new const reference to applicable BufferView. * InsetBase - xo(), yo(), covers() and neverIndent() are now const. * InsetText::setViewCache(): deleted All other changes are due to the LyXText and InsetBase API changes. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@15618 a592a061-630c-0410-9148-cb99ea01b6c8

|
* Calling LyXText::getFont is slow. While rebreaking we scan a
|
|
* paragraph from left to right calling getFont for every char. This
|
|
* simple class address this problem by hidding an optimization trick
|
|
* (not mine btw -AB): the font is reused in the whole font span. The
|
|
* class handles transparently the "hidden" (not part of the fontlist)
|
|
* label font (as getFont does).
