Tweaks to Grid/Escalator column size handling (#12145)
- ScrollbarBundle: removed delays in scroll handling that were only
needed for IE8, added possibility to update offsetSize and scrollSize at
the same time in order to avoid triggering unnecessary scrollbar
visibility change events during the intermediate state.
- ColumnConfigurator: added new method that allows setting column widths
without triggering element size recalculations.
- EscalatorProxy: added implementation of the new method to
ColumnConfigurationProxy.
- Escalator: switched to use new methods in ScrollbarBundle and
ColumnConfigurator, added a pixel to a scrollbar offsetSize calculation
that was for some reason consistently one pixel too low, removed
duplicate method calls from sectionHeightCalculated handling as those
are already handled by the calling method and can cause incorrect
intermediate state and unnecessary scrollbar visibility change events,
added implementation of the new method to ColumnConfigurationImpl with
the element size recalculations made optional.
- Grid: updated column minimum width calculations to take into account
the potential presence of a resize handle, updated expand ratio handling
to not trigger element size recalculations until the entire handling is
finished.
- Test for column width handling when there are multiple columns with
setMinimumWidthFromContent(false)
Fixes #12139
Updated row and spacer handling for Escalator (#11438)
Updated row and spacer handling for Escalator.
Main changes:
- Spacers are only maintained and checked for rows that have DOM
representation, and not at all if there is no details generator. This
gives notable performance improvements to some particularly large Grids
- Escalator no longer tries to trim away any rows that don't fit within
the viewport just because a details row gets opened in Grid. This leads
to some increase in simultaneous DOM elements, but simplifies the logic
considerably. For example opening or closing details rows doesn't
require checking the overall content validity beyond the details row
itself anymore, but some repositioning at most. There are also no longer
any orphaned spacers without corresponding DOM rows.
- Spacers are better integrated into the overall position calculations.
- Some public methods that are no longer used by Escalator or have
changed functionality or order of operations. Any extending classes that
tap into row, spacer, or scroll position handling are likely to need
reworking after this update.
- Auto-detecting row height is delayed until Escalator is both attached
and displayed.
Improvements to detail row index handling. (#11345)
- Escalator should notify when an existing details row is moved to a new
index.
- Grid and DetailsManagerConnector should update their internal indexing
when details manager index changes in Escalator.
Fixes to displaying Grid in a detail row. (#11147)
- Multiple headers shouldn't stack behind each other.
- Body rows shouldn't get stuck to default row height.
- Compatibility version's hidable row selector shouldn't try to
calculate row heights based on rows that haven't been added to DOM yet.
Fixes #7674
Escalator supports adding spacer elements into DOM. (#16644)
This is the first step towards Grid's details rows: Escalator puts spacer elements
in the DOM, and is able to scroll around with them. The spacers are put in their
correct locations, but they will not affect the normal row elements in any way at
this time.

Grid.onStateChange is now about 40% faster when adding columns,
and setting several column widths has now way less overhead.
