- get rid of the cached Dimension. Text inset dimensions are saved in ParagraphMetrics and mathed maintain their own dimension where needed. - width(), ascent(), descent(): deleted. - dimension(): now needs a valid BufferView. - metrics(): now void. * BufferView::getCoveringInset(): simplify. * ParagraphMetrics(): now cache inset dimensions. git-svn-id: svn://svn.lyx.org/lyx/lyx-devel/trunk@20420 a592a061-630c-0410-9148-cb99ea01b6c8

// This is Juergen's rewrite of the tabular (table) support.
|
|
|
|
// Things to think of when designing the new tabular support:
|
|
// - color support (colortbl, color)
|
|
// - decimal alignment (dcloumn)
|
|
// - custom lines (hhline)
|
|
// - rotation
|
|
// - multicolumn
|
|
// - multirow
|
|
// - column styles
|
|
|
|
// This is what I have written about tabular support in the LyX3-Tasks file:
|
|
//
|
|
// o rewrite of table code. Should probably be written as some
|
|
// kind of an inset. [Done]
|
|
// o enhance longtable support
|
|
|
|
// Lgb
