at the pixel level. The odd pixel is always given to the right and bottom
cell borders whenever possible, and to the top and left table border otherwise.
types, and mColGroups. Besides being cleaner and easier to maintain, this should speed some things up slightly
because I don't have to check display types every time I iterate through colgroup frames. I *know*
mColGroups contains only colgroups. I might do the same for rowgroups (that is, keep unknown frame types
in their own list as well.) But that's optional.
the inner table frame used to incorrectly create actual content objects for anonymous colgroups and cols. Now,
it just creates frames as appropriate, not content. To support this, I added some pseudo style contexts and
related atoms.
C++ compiler is strict about getting 'const' right. Most of the changes
are to add 'const' to the type casts for the second argument of the
GetStyleData method, which wants a const reference.
the layout strategy can now query the outer frame for the caption min width,
and use it to expand the table if necessary
did some related cleanup while I was in there.
table frames no longer assume they are n levels below the inner table frame
table frames no longer assume their child frames are always the expected type of
frame. Now they check the display type and use that as sufficient proof that the frame
is of the right type. This implies a heavy reliance on the frame construction code to do
the right thing and always stamp out the right kind of frame for a given display type.
from their respective InitalReflow() methods.
table-layout=fixed now completely skips pass1 reflow and doesn't require maxElementSize
information, saving a tremendous amount of time during initial reflow.
moved *IsSpannedInto and *HasSpanningCells into cellmap, giving us the oppurtunity
to easily cache results if we want. These methods are still accessed through nsTableFrame.
changed nsTableFrame::GetCellAt to nsTableFrame::GetCellFrameAt to make it more clear what
the method returns: a frame, not content.
nsHTMLAtoms.cpp,h added some HTML 4 strings for tables
nsHTMLParts.h added constructors for new table content classes
nsGenericHTMLElement.cpp,h added table frame creation, common table attribute parsing
nsHTMLTable*Element.cpp these are the new table content classes
nsHTMLContentSink.cpp enabled the new content and removed the old
nsHTMLStyleSheet.cpp fixed the table style optimizations to work with new content
nsTable*Frame.cpp these work with the new content
aFilter is useful for determining if a frame should output itself during
a List(). In any event, the children of the frame are always processed.
added nsIListFilter, an interface for any object that wants to act like a filter for frame dumps
added static NS_LAYOUT nsIListFilter * GetFilter(nsString *aFilterName);
currently, only TableListFilter implements nsIListFilter.
in response to List(...TableListFilter), the frame model is dumped in a way that is useful
for table layout regression testing. Currently this is controlled by command line switches on the viewer app.
