From 145527207538b6ee1018cb77e6705912c29f8a9f Mon Sep 17 00:00:00 2001 From: wolfbeast Date: Sat, 2 Nov 2019 22:39:03 +0100 Subject: Issue #146 - Part 1: Draw each table's background on their own display list items. This patch does the following things: 1. Creates nsDisplayTableBorderCollapse that draws all collapse border of tables. 2. Stops the use of nsDisplayTableBorderBackground. 3. Lets column and column group frames generate display items. 4. When traversing the table, also traverses the column and column group frames. 5. For each type of table frame (col group, col, row group, row and cell), draws their own background. --- layout/tables/nsTableCellFrame.cpp | 103 +++++++++++++++---------------------- 1 file changed, 42 insertions(+), 61 deletions(-) (limited to 'layout/tables/nsTableCellFrame.cpp') diff --git a/layout/tables/nsTableCellFrame.cpp b/layout/tables/nsTableCellFrame.cpp index dea82ea59..bac8d387f 100644 --- a/layout/tables/nsTableCellFrame.cpp +++ b/layout/tables/nsTableCellFrame.cpp @@ -484,70 +484,51 @@ nsTableCellFrame::BuildDisplayList(nsDisplayListBuilder* aBuilder, const nsDisplayListSet& aLists) { DO_GLOBAL_REFLOW_COUNT_DSP("nsTableCellFrame"); - if (IsVisibleInSelection(aBuilder)) { - nsTableFrame* tableFrame = GetTableFrame(); - int32_t emptyCellStyle = GetContentEmpty() && !tableFrame->IsBorderCollapse() ? - StyleTableBorder()->mEmptyCells - : NS_STYLE_TABLE_EMPTY_CELLS_SHOW; - // take account of 'empty-cells' - if (StyleVisibility()->IsVisible() && - (NS_STYLE_TABLE_EMPTY_CELLS_HIDE != emptyCellStyle)) { - // display outset box-shadows if we need to. - bool hasBoxShadow = !!StyleEffects()->mBoxShadow; - if (hasBoxShadow) { - aLists.BorderBackground()->AppendNewToTop( - new (aBuilder) nsDisplayBoxShadowOuter(aBuilder, this)); - } - - // display background if we need to. - if (aBuilder->IsForEventDelivery() || - !StyleBackground()->IsTransparent() || StyleDisplay()->mAppearance) { - if (!tableFrame->IsBorderCollapse()) { - nsDisplayBackgroundImage::AppendBackgroundItemsToTop(aBuilder, - this, - GetRectRelativeToSelf(), - aLists.BorderBackground()); - } else if (aBuilder->IsAtRootOfPseudoStackingContext() || - aBuilder->IsForEventDelivery()) { - // The cell background was not painted by the nsTablePainter, - // so we need to do it.
