Bug 279033 – Refactor `computePositionedLogicalWidthUsing` to use shrink-to-fit in one step

• Status: REOPENED
• Component: Layout and Rendering

[Ahmad Saleem]

Hi Team,

This is just refactoring in `computePositionedLogicalWidthUsing` by reduce reuse of variables:

auto shrinkToFitLogicalWidth = [this](LayoutUnit availableLogicalWidth, LayoutUnit bordersPlusPadding) -> LayoutUnit {
            LayoutUnit preferredLogicalWidth = maxPreferredLogicalWidth() - bordersPlusPadding;
            LayoutUnit preferredMinLogicalWidth = minPreferredLogicalWidth() - bordersPlusPadding;
            return std::min(std::max(preferredMinLogicalWidth, availableLogicalWidth), preferredLogicalWidth);
        };

and

then changing from:

computedValues.m_extent = std::min(std::max(preferredMinWidth, availableWidth), preferredWidth);

to:

computedValues.m_extent = shrinkToFitLogicalWidth(availableSpace - logicalLeftValue, bordersPlusPadding);

Thanks!

We can even use std:clamp here - return std::clamp(availableLogicalWidth, preferredMinLogicalWidth, preferredLogicalWidth);
