Message:

MathML preferred widths should not depend on layout information
​https://bugs.webkit.org/show_bug.cgi?id=107353

Reviewed by Levi Weintraub.

Source/WebCore:

  • mathml/MathMLTextElement.cpp:

(WebCore::MathMLTextElement::attach):
(WebCore::MathMLTextElement::childrenChanged):

  • mathml/MathMLTextElement.h:

Need to update the render tree when the text of a <mo> changes.

  • rendering/mathml/RenderMathMLBlock.cpp:

(WebCore::RenderMathMLBlock::RenderMathMLBlock):

  • rendering/mathml/RenderMathMLBlock.h:
  • rendering/mathml/RenderMathMLFenced.cpp:

(WebCore::RenderMathMLFenced::makeFences):
(WebCore::RenderMathMLFenced::styleDidChange):
Need to update the rendertree to apply operator stretching.

  • rendering/mathml/RenderMathMLOperator.cpp:

(WebCore::RenderMathMLOperator::glyphHeightForCharacter):
(WebCore::RenderMathMLOperator::widthForCharacter):
(WebCore::RenderMathMLOperator::computeIntrinsicLogicalWidths):
(WebCore::RenderMathMLOperator::stretchDisabledByMarkup):
(WebCore::RenderMathMLOperator::firstTextCharacter):
(WebCore::RenderMathMLOperator::stretchyCharacterIndex):
(WebCore::RenderMathMLOperator::updateFromElement):
(WebCore::RenderMathMLOperator::firstLineBoxBaseline):
-Make the preferred widths of operators the max of all possible
characters to be used in the operator and center the operator in that width.
-For stretching where we don't use multiple glyphs, use transforms
instead of font-size. This both looks better and avoids affecting the width.
-Now that preferred widths don't depends on height, we don't need to
override computePreferredLogicalWidths at all in MathML code.

  • rendering/mathml/RenderMathMLOperator.h:
  • rendering/mathml/RenderMathMLRoot.cpp:

(WebCore::RenderMathMLRoot::index):
Tighten up the type.

(WebCore::RenderMathMLRoot::layout):
Move the laying out of children to the layout method.

  • rendering/mathml/RenderMathMLRoot.h:
  • rendering/mathml/RenderMathMLRow.cpp:

(WebCore::RenderMathMLRow::logicalHeightExcludingOperators):
(WebCore::RenderMathMLRow::stretchOperatorsAndLayout):
(WebCore::RenderMathMLRow::layout):
Move the laying out of children and the subsequent setting of stretchHeight
to the layout method.
