/* ~*~ Table Background Painting ~*~
|
||||
|
||||
Mozilla's Table Background painting follows CSS2.1:17.5.1
|
||||
That section does not, however, describe the effect of
|
||||
borders on background image positioning. What we do is:
|
||||
|
||||
- in separate borders, the borders are passed in so that
|
||||
their width figures in image positioning, even for rows/cols, which
|
||||
don't have visible borders. This is done to allow authors
|
||||
to position row backgrounds by, for example, aligning the
|
||||
top left corner with the top left padding corner of the
|
||||
top left table cell in the row in cases where all cells
|
||||
have consistent border widths. If we didn't honor these
|
||||
invisible borders, there would be no way to align
|
||||
backgrounds with the padding edges, and designs would be
|
||||
lost underneath the border.
|
||||
|
||||
- in collapsing borders, because the borders collapse, we
|
||||
use the -continuous border- width to synthesize a border
|
||||
style and pass that in instead of using the element's
|
||||
assigned style directly.
|
||||
|
||||
The continuous border on a given edge of an element is
|
||||
the collapse of all borders guaranteed to be continuous
|
||||
along that edge. Cell borders are ignored (because, for
|
||||
example, setting a thick border on the leftmost cell
|
||||
should not shift the row background over; this way a
|
||||
striped background set on <tr> will line up across rows
|
||||
even if the cells are assigned arbitrary border widths.
|
||||
|
||||
For example, the continuous border on the top edge of a
|
||||
row group is the collapse of any row group, row, and
|
||||
table borders involved. (The first row group's top would
|
||||
be [table-top + row group top + first row top]. It's bottom
|
||||
would be [row group bottom + last row bottom + next row
|
||||
top + next row group top].)
|
||||
The top edge of a column group likewise includes the
|
||||
table top, row group top, and first row top borders. However,
|
||||
it *also* includes its own top border, since that is guaranteed
|
||||
to be continuous. It does not include column borders because
|
||||
those are not guaranteed to be continuous: there may be two
|
||||
columns with different borders in a single column group.
|
||||
|
||||
An alternative would be to define the continuous border as
|
||||
[table? + row group + row] for horizontal
|
||||
[table? + col group + col] for vertical
|
||||
This makes it easier to line up backgrounds across elements
|
||||
despite varying border widths, but it does not give much
|
||||
flexibility in aligning /to/ those border widths.
|
||||
*/
|
||||
|
||||
|
||||
/* ~*~ TableBackgroundPainter ~*~
|
||||
|
||||
The TableBackgroundPainter is created and destroyed in one painting call.
|
||||
Its principal function is PaintTable, which paints all table element
|
||||
backgrounds. The initial code in that method sets up an array of column
|
||||
data that caches the background styles and the border sizes for the
|
||||
columns and colgroups in TableBackgroundData structs in mCols. Data for
|
||||
BC borders are calculated and stashed in a synthesized border style struct
|
||||
in the data struct since collapsed borders aren't the same width as style-
|
||||
assigned borders. The data struct optimizes by only doing this if there's
|
||||
an image background; otherwise we don't care. //XXX should also check background-origin
|
||||
The class then loops through the row groups, rows, and cells. At the cell
|
||||
level, it paints the backgrounds, one over the other, inside the cell rect.
|
||||
|
||||
The exception to this pattern is when a table element creates a (pseudo)
|
||||
stacking context. Elements with stacking contexts (e.g., 'opacity' applied)
|
||||
are <dfn>passed through</dfn>, which means their data (and their
|
||||
descendants' data) are not cached. The full loop is still executed, however,
|
||||
so that underlying layers can get painted at the cell level.
|
||||
|
||||
The TableBackgroundPainter is then destroyed.
|
||||
|
||||
Elements with stacking contexts set up their own painter to finish the
|
||||
painting process, since they were skipped. They call the appropriate
|
||||
sub-part of the loop (e.g. PaintRow) which will paint the frame and
|
||||
descendants.

|

// Section 17.5.1.) If a cell is positioned, we do not expect the row

// background to move. On the other hand, the backgrounds of layers *above*
|

// the positioned part are taken along for the ride -- for example,
|
||||
// positioning a row group will also cause the row background to be drawn in
|
||||
// the new location, unless it has further positioning applied.
|
||||
//
|
||||
// Each table part layer has its position stored in the coordinate space of
|
||||
// the layer below (which is to say, its geometric parent), and the stored
|
||||
// position is the post-relative-positioning one. The position of each
|
||||
// background layer rect is thus determined by peeling off successive table
|
||||
// part layers, removing the contribution of each layer's positioning one by
|
||||
// one. Every rect we generate will be the same size, the size of the cell
|
||||
// space.
