Sorry for the delay. Too much going on right now. On 19.07.2006 01:37:57 Patrick Paul wrote: > Just to make sure I understand things correctly, the element list > construction needs to be seperated from the line breaking algorithm ONLY > when using it for auto table layout ?
I'd state it differently: Element list contruction needs to be separated from the line breaking algorithm in order so the auto table layout can access the element lists before the line breaking can occur. ATM, yes, it's only used for auto table layout. > I am asking this because the > LineLayoutManager is not used exclusively by the TableLayoutManager, right ?

The existing one needs to be adjusted. getNextKnuthElements() in the context of the LineLayoutManager means returning a block-level element list which cannot be provided at the point where you need the inline-level element lists. So you may need to come up with a mechanism that you can call on the block-level LMs inside the table-cell so they descend down to the LineLayoutManagers and issue the construction of the inline element lists. Ideally, the LineLayoutManagers won't have to recreate the element lists when the real getNextKnuthElements() call happens but they will automatically create those element lists when they are not available, yet (i.e. in cases outside a table).
