From 8ff295747e7f5e205313e4405d5a63ce23fca993 Mon Sep 17 00:00:00 2001 From: Gaming4JC Date: Sat, 28 Sep 2019 23:36:05 -0400 Subject: Issue #1230 - Part 1: Fix Back-computing percentages for intrinsic sizing in Layout CSS-Grid List of relevant patches applied: 1398537 part 2 - [css-multicol] Implement percentages for 'column-gap' (Gecko part). 1434478 part 1 - [css-grid] Stop back-computing percentage grid gaps when the percentage basis is indefinite. Treat them as zero sized instead. 1434478 part 2 - Stop back-computing percentage padding/margin when the percentage basis is indefinite. Treat them as zero sized instead. 1434478 part 3 - Remove IntrinsicISizeOffsetData::hPctPadding/hPctMargin members since they are now unused. 1434478 part 4 - Factor out constants like NS_UNCONSTRAINEDSIZE so they can be used in headers without needing nsIFrame.h (idempotent patch). 1434478 part 5 - Create nsLayoutUtils::ResolveToLength for resolving CSS (idempotent patch). 1434478 part 6 - Propagate a percentage basis to nsIFrame::IntrinsicISizeOffsets for resolving padding/margin. This is needed only for CSS Grid since in other cases we're only using IntrinsicISizeOffsets in the inline-axis and the percentage basis is always indefinite for *intrinsic sizing*. When calculating the intrinsic size of grid items in the grid container's block axis however, we do have a definite size for the grid area in the inline-axis and it should be used per: https://drafts.csswg.org/css-grid/#algo-overview "2. Next, the track sizing algorithm resolves the sizes of the grid rows, using the grid column sizes calculated in the previous step." (Percentage padding/margin for grid items is always resolved against the grid area's inline-size nowadays.) --- layout/tables/nsTableCellFrame.cpp | 6 +++--- 1 file changed, 3 insertions(+), 3 deletions(-) (limited to 'layout/tables/nsTableCellFrame.cpp') diff --git a/layout/tables/nsTableCellFrame.cpp b/layout/tables/nsTableCellFrame.cpp index 316a96613..dea82ea59 100644 --- a/layout/tables/nsTableCellFrame.cpp +++ b/layout/tables/nsTableCellFrame.cpp @@ -796,12 +796,12 @@ nsTableCellFrame::GetPrefISize(nsRenderingContext *aRenderingContext) } /* virtual */ nsIFrame::IntrinsicISizeOffsetData -nsTableCellFrame::IntrinsicISizeOffsets() +nsTableCellFrame::IntrinsicISizeOffsets(nscoord aPercentageBasis) { - IntrinsicISizeOffsetData result = nsContainerFrame::IntrinsicISizeOffsets(); + IntrinsicISizeOffsetData result = + nsContainerFrame::IntrinsicISizeOffsets(aPercentageBasis); result.hMargin = 0; - result.hPctMargin = 0; WritingMode wm = GetWritingMode(); result.hBorder = GetBorderWidth(wm).IStartEnd(wm); -- cgit v1.2.3 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.
