  • https://github.com/CollaboraOnline/online/pull/14219 (merged) - Now the dynamic zoom is recalculated when the sidebar shows up for the first time. This way it doesn't cover the right half of the document.
  • Now working on Windows Theming Issues & while it compiles, looking at Comments regressions.
    • Unknowingly Clogged the CI with 30+ backport patches, sorry :_). Reverted those changes as a) theyintroduced new strings and b) they were big changes, quite risky to push near a release.

  • Remove initial selection styling in View Mode dropdown (In Review)
  • Intially we had planned to remove the selection but due to accessibilty this breaks keyboard navigation. So now the plan is to add a style to the selected/active mode
  • Writer: Shorten label to “Compare Document...” in Compare menu (Approved)
  • Now: creating new table style icons

  • (In Progress) - XLSX Scaled image width import issue (tdf#169332)

    • - Width calculations seems fine.

    • But column width of Excel and Calc seems different. (Caolan)

      • This seems the main reason why width of an image is different in both application. Image width sticks to the column location in Calc rather than its width on Excel.

      • Column width is not a pure point measurement. Instead, it’s based on the number of characters of the default font that can fit in the cell. For example, a column width of 8.43 means about 8 characters of the default font (Calibri, size 11) fit across the cell. Excel internally converts this into points for display, but it’s not a straight “height vs. width” comparison.

      • Now: investigate where Calc does conversion of widths in terms of these idealized width points to real units.

Karthik

Calc Interop Issues (XLS → XLSX ): Merged:

  • Writer Captions: Category is not stored in navigator
  • DOCX: gap not presereved
    • I found the reason of the buggy behaviour
    • Planned changes in d092521b2595963dcf0928f5fee7ed1903ff4aef caused the bug
    • I’m investigating what happens when I revert partially. Unfortunately there is no clue in the commit what was the issue before
    • There is a problem to run tests locally. And tests are a little bit slow on my local. Lets see.

Multiline hyprlink cursor position fix:

  • Found a way to alter cursor positions in edit engine.. it seems to work now .. bur not made PR yet.
  • There are other glitches around this (like selecting it, or bigger font after hypelink), because it is a partially implemented feature (not a real regression), inside of a hack .. multiline hyperlinks was never supported on edit mode, in editengine .. there was a hack in the paint .. that was moved the hyperlink into a new line.. But the algorithm normally supports wapping text into lines.. where a hyperlink is not a text but 1 symbol, so it cannot even store it as multiline.. A real fix for the whole area would require a big re-implementation (adding support for multi lines into lines), or a smaller but still huge refactor (replacing hyperlink symbols with text).

    • Fixed some chart style CI problems (there are still a few but they can wait.)

Darshan

Consider the custom logo for loading spinner:

https://github.com/CollaboraOnline/online/pull/14248

  • logoURL parameter enables users to override the default logo with their own branding.
  • As an enhancement, the same logoURL should be applied to the loading spinner.
  • If a custom logoURL is provided, the loading spinner should use it instead of the default logo.
  • If no logoURL is set, the spinner should fall back to the default logo.
