Bumps react-resizable-panels from 2.1.9 to 4.5.5.

Release notes

Sourced from react-resizable-panels's releases.

4.5.5

  • 641: Removed aria-orientation role from root Group element as this was invalid according to the ARIA spec; (for more information see the discussion on issue #640)
  • 642: Bugfix: Fix collapsible Panel regression introduced in 4.5.3

4.5.4

  • 638: Panel avoids unnecessary re-renders in response to mouse-hover state.

4.5.3

  • 635: Expand pre-collapsed panels if drug past the halfway point for more consistent collapse/expand behavior.
  • 631: Bugfix: Panels set max-width and max-height to 100% to fix potential CSS overflow bug.

4.5.2

  • 626: Decrease default hit target size for Separator and Panel edges; make configurable via a new Group prop.

4.5.1

  • 624: Bugfix: Fallback to alternate CSS cursor styles for Safari
Safari Chrome, Firefox
grab move
col-resize ew-resize
row-resize ns-resize

4.5.0

  • 616: Replace Separator and Panel edge hit-area padding with a minimum size threshold based on Apple's user interface guidelines. Separators that are large enough will no longer be padded; separators that are too small (or panels without separators) will more or less function like before. This should not have much of a user-facing impact other than an increase in the click target area. (Previously I was not padding enough, as per Apple's guidelines.)
  • 615, 620: Double-clicking on a Separator resets its associated Panel to its default-size (see video below); double-click will have no impact on panels without default sizes
  • 622: Bugfix: Panels within vertical groups are now properly sized in Safari
  • 618: Bugfix: Don't override adoptedStyleSheets

Demo of double-clicking on a separator:

dbl-click.mov

4.4.2

  • 610: Fix calculated cursor style when "pointermove" event is has low-precision/rounded clientX and clientY values

4.4.1

  • 600: Bugfix: Collapsible Panel should treat defaultSize={0} as collapsed on mount

4.4.0

  • 599: Add new onLayoutChanged prop to Group.

For layout changes caused by pointer events, this method is not called until the pointer has been released. This callback should be used if you're doing something like saving a layout as it is called less frequently than the previous approach.

The useDefaultLayout hook has also been updated to use this callback (though it will continue to support the old callback as well, with a @deprecation tag).

4.3.3

  • 595: Don't call event.preventDefault() on "pointerup" unless a handle was actively dragged
