| 1535 | * Before reflow, intrinsic inline-size calculation is done using GetMinISize |
| 1536 | * and GetPrefISize. This used to be known as pass 1 reflow. |
| 1537 | * |
| 1538 | * After the intrinsic isize calculation, the table determines the |
| 1539 | * column widths using BalanceColumnISizes() and |
| 1540 | * then reflows each child again with a constrained avail isize. This reflow is |
| 1541 | * referred to as the pass 2 reflow. |
| 1542 | * |
| 1543 | * A special bsize reflow (pass 3 reflow) can occur during an initial or resize |
| 1544 | * reflow if (a) a row group, row, cell, or a frame inside a cell has a percent |
| 1545 | * bsize but no computed bsize or (b) in paginated mode, a table has a bsize. |
| 1546 | * (a) supports percent nested tables contained inside cells whose bsizes aren't |
| 1547 | * known until after the pass 2 reflow. (b) is necessary because the table |
| 1548 | * cannot split until after the pass 2 reflow. The mechanics of the special |
| 1549 | * bsize reflow (variety a) are as follows: |
| 1550 | * |
| 1551 | * 1) Each table related frame (table, row group, row, cell) implements |
| 1552 | * NeedsSpecialReflow() to indicate that it should get the reflow. It does |
| 1553 | * this when it has a percent bsize but no computed bsize by calling |
| 1554 | * CheckRequestSpecialBSizeReflow(). This method calls |
| 1555 | * RequestSpecialBSizeReflow() which calls SetNeedSpecialReflow() on its |
| 1556 | * ancestors until it reaches the containing table and calls |
| 1557 | * SetNeedToInitiateSpecialReflow() on it. For percent bsize frames inside |
| 1558 | * cells, during DidReflow(), the cell's NotifyPercentBSize() is called |
| 1559 | * (the cell is the reflow input's mPercentBSizeObserver in this case). |
| 1560 | * NotifyPercentBSize() calls RequestSpecialBSizeReflow(). |
| 1561 | * |
| 1562 | * XXX (jfkthame) This comment appears to be out of date; it refers to |
| 1563 | * methods/flags that are no longer present in the code. |
| 1564 | * |
| 1565 | * 2) After the pass 2 reflow, if the table's NeedToInitiateSpecialReflow(true) |
| 1566 | * was called, it will do the special bsize reflow, setting the reflow |
| 1567 | * input's mFlags.mSpecialBSizeReflow to true and mSpecialHeightInitiator to |
| 1568 | * itself. It won't do this if IsPrematureSpecialHeightReflow() returns true |
| 1569 | * because in that case another special bsize reflow will be coming along |
| 1570 | * with the containing table as the mSpecialHeightInitiator. It is only |
| 1571 | * relevant to do the reflow when the mSpecialHeightInitiator is the |
| 1572 | * containing table, because if it is a remote ancestor, then appropriate |
| 1573 | * bsizes will not be known. |
| 1574 | * |
| 1575 | * 3) Since the bsizes of the table, row groups, rows, and cells was determined |
| 1576 | * during the pass 2 reflow, they return their last desired sizes during the |
| 1577 | * special bsize reflow. The reflow only permits percent bsize frames inside |
| 1578 | * the cells to resize based on the cells bsize and that bsize was |
| 1579 | * determined during the pass 2 reflow. |
| 1580 | * |
| 1581 | * So, in the case of deeply nested tables, all of the tables that were told to |
| 1582 | * initiate a special reflow will do so, but if a table is already in a special |
| 1583 | * reflow, it won't inititate the reflow until the current initiator is its |
| 1584 | * containing table. Since these reflows are only received by frames that need |
| 1585 | * them and they don't cause any rebalancing of tables, the extra overhead is |
| 1586 | * minimal. |
| 1587 | * |
| 1588 | * The type of special reflow that occurs during printing (variety b) follows |
| 1589 | * the same mechanism except that all frames will receive the reflow even if |
| 1590 | * they don't really need them. |
| 1591 | * |
| 1592 | * Open issues with the special bsize reflow: |
| 1593 | * |
| 1594 | * 1) At some point there should be 2 kinds of special bsize reflows because (a) |
| 1595 | * and (b) above are really quite different. This would avoid unnecessary |
| 1596 | * reflows during printing. |
| 1597 | * |
| 1598 | * 2) When a cell contains frames whose percent bsizes > 100%, there is data |
| 1599 | * loss (see bug 115245). However, this can also occur if a cell has a fixed |
| 1600 | * bsize and there is no special bsize reflow. |
| 1601 | * |
| 1602 | * XXXldb Special bsize reflow should really be its own method, not |
| 1603 | * part of nsIFrame::Reflow. It should then call nsIFrame::Reflow on |
| 1604 | * the contents of the cells to do the necessary block-axis resizing. |

| 5063 | // inline-start of the table, store its block-start inline-start corner. |
| 5064 | // |
| 5065 | // 2) If the cell is at the inline-start of the table, store the block-start |
| 5066 | // inline-start corner. |
| 5067 | // |
| 5068 | // 3) If the cell is at the block-start inline-end of the table, or not at the |
| 5069 | // block-start of the table, store the block-start inline-end corner. |
| 5070 | // |
| 5071 | // 4) If the cell is at the block-end inline-end of the table, store the |
| 5072 | // block-end inline-end corner. |
| 5073 | // |
| 5074 | // 5) If the cell is at the block-end of the table, store the block-end |
