From 64ffe81c5551d1fabb12aa2d529ed5711bbbe965 Mon Sep 17 00:00:00 2001 From: win7-7 Date: Fri, 8 May 2020 01:21:41 +0300 Subject: Issue #1355 - Better way to create display items for column backgrounds Part 1: Remove current table item, as it's never set. Part 2: Get rid of generic table painting code, and handle each class separately. Part 4: Hoist outline skipping into col(group) frame code. Part 5: Skip box-shadow for table column and column groups. Part 6: Store column and column group backgrounds separately, and then append them before the rest of the table contents. Part 7: Pass rects in display list coordinates to AppendBackgroundItemsToTop. Part 8: Create column and column group background display items as part of the cell's BuildDisplayList. Part 9: Used cached values instead of calling nsDisplayListBuilder::ToReferenceFrame when possible, since it can be expensive when the requested frame isn't the builder's current frame. Part 10: Make sure we build display items for table parts where only the normal position is visible, since we may need to create background items for ancestors at that position. Part 11: Create an AutoBuildingDisplayList when we create background items for table columns and column groups, so that we initialize the invalidation state correctly. --- layout/base/nsDisplayList.cpp | 29 ++- layout/base/nsDisplayList.h | 25 +- layout/forms/nsButtonFrameRenderer.cpp | 4 +- layout/forms/nsFieldSetFrame.cpp | 6 +- layout/generic/nsFrame.cpp | 44 +++- layout/mathml/nsMathMLChar.cpp | 3 +- .../reftests/position-relative/1409114-1-ref.html | 12 + layout/reftests/position-relative/1409114-1.html | 11 + layout/reftests/position-relative/1409114-2.html | 13 + layout/reftests/position-relative/1409114-3.html | 13 + layout/reftests/position-relative/reftest.list | 3 + ...er-collapse-opacity-table-column-group-ref.html | 6 +- .../border-collapse-opacity-table-column-ref.html | 6 +- ...er-separate-opacity-table-column-group-ref.html | 6 +- .../border-separate-opacity-table-column-ref.html | 6 +- layout/reftests/table-background/reftest.list | 3 + .../table-col-overlapping-ref.html | 28 ++ .../table-background/table-col-overlapping.html | 28 ++ .../table-background/table-col-span-1-ref.html | 15 ++ .../table-background/table-col-span-1.html | 15 ++ layout/tables/nsTableCellFrame.cpp | 51 +++- layout/tables/nsTableColFrame.cpp | 8 +- layout/tables/nsTableColGroupFrame.cpp | 8 +- layout/tables/nsTableFrame.cpp | 286 ++++----------------- layout/tables/nsTableFrame.h | 95 +++---- layout/tables/nsTableRowFrame.cpp | 57 +++- layout/tables/nsTableRowFrame.h | 5 + layout/tables/nsTableRowGroupFrame.cpp | 39 ++- layout/xul/nsGroupBoxFrame.cpp | 3 +- 29 files changed, 488 insertions(+), 340 deletions(-) create mode 100644 layout/reftests/position-relative/1409114-1-ref.html create mode 100644 layout/reftests/position-relative/1409114-1.html create mode 100644 layout/reftests/position-relative/1409114-2.html create mode 100644 layout/reftests/position-relative/1409114-3.html create mode 100644 layout/reftests/table-background/table-col-overlapping-ref.html create mode 100644 layout/reftests/table-background/table-col-overlapping.html create mode 100644 layout/reftests/table-background/table-col-span-1-ref.html create mode 100644 layout/reftests/table-background/table-col-span-1.html diff --git a/layout/base/nsDisplayList.cpp b/layout/base/nsDisplayList.cpp index a869564a4..55461f7c0 100644 --- a/layout/base/nsDisplayList.cpp +++ b/layout/base/nsDisplayList.cpp @@ -721,7 +721,6 @@ nsDisplayListBuilder::nsDisplayListBuilder(nsIFrame* aReferenceFrame, : mReferenceFrame(aReferenceFrame), mIgnoreScrollFrame(nullptr), mLayerEventRegions(nullptr), - mCurrentTableItem(nullptr), mCurrentFrame(aReferenceFrame), mCurrentReferenceFrame(aReferenceFrame), mCurrentAGR(&mRootAGR), @@ -731,6 +730,7 @@ nsDisplayListBuilder::nsDisplayListBuilder(nsIFrame* aReferenceFrame, mGlassDisplayItem(nullptr), mScrollInfoItemsForHoisting(nullptr), mMode(aMode), + mTableBackgroundSet(nullptr), mCurrentScrollParentId(FrameMetrics::NULL_SCROLL_ID), mCurrentScrollbarTarget(FrameMetrics::NULL_SCROLL_ID), mCurrentScrollbarFlags(0), @@ -926,7 +926,6 @@ nsDisplayListBuilder::~nsDisplayListBuilder() { "All frames should have been unmarked");
