v0.20.0

• Simplification of TreeState usage
  • key / mouse / selection methods don't require the items anymore. Instead, they assume the state of last render.
  • add TreeState::click_at and TreeState::rendered_at #36
  • add TreeState::opened and simplify TreeState::selected for direct access to current values by reference
  • rename TreeState::select_visible_relative to TreeState::select_relative due to confusion what 'visible' means
  • less internal clones
• Tree::new takes items as reference. #32
• TreeItem::style is now part of TreeItem::text
• add TreeItem::identifier for access to the identifier of the item #38

BREAKING CHANGES:

• TreeState key / mouse / selection methods no longer take the items argument.
• TreeState::selected returns a reference instead of a Vec.
• TreeState is no longer Cloneable due to holding the state of last render
• TreeItem::style is gone and used from TreeItem::text

Thanks to @sandercm and @fioncat for their PRs and @thscharler for the ideas leading to some improvements ✨

• refactor!: remove get_identifier_without_leaf a2f8100

BREAKING CHANGES:

• state methods return when something changed ed9a54a
• get_identifier_without_leaf is gone. Reimplement yourself or use Vec::pop() a2f8100

v0.18.0

• fix!: remove start_corner 85bfecc
• perf: get item.height() less often on render 4130a80
• perf: prefer into_iter() over clone() 86458ff
• experimental scrollbar support (API might change on any release)

BREAKING CHANGES: start_corner is gone

v0.17.0

• feat: scroll independently from selection 01726df
• feat: select_*() returns whether it changed 969b78a
• build: update to ratatui 0.26 4cbe932
• perf(key_left): remove clones 632a95f
• perf!: flatten -> TreeState::flatten d1a2412

BREAKING CHANGES:

flatten -> TreeState::flatten d1a2412

-tui_tree_widget::flatten(state.get_all_opened(), &items);
+state.flatten(&items);

v0.16.0

Nothing changed besides the ratatui version which was updated to v0.25

v0.15.0

• feat: generic identifier (#27) b914819
• feat: add TreeState::select_visible_index and relative 9a47f5e

BREAKING CHANGE: the generic identifier requires some different method arguments.
Mainly this introduces the identifier argument on TreeItem::new.
See its documentation on docs.rs for more background.

v0.14.0

• build: update to ratatui 0.24 87e1bb4
• perf!: accept Vec explicitly b4d0c30
• perf: use more const functions 0d9d132

BREAKING CHANGE: in some spaces a Vec needs to be supplied explicitly. This prevents accidental clones. See b4d0c30

v0.13.0

• feat: migrate to ratatui (#26) 3f30eff
• build: ignore msrv 17de58e

v0.12.0

• feat: add TreeItem::children() c8c5a37
• feat: configure node open state symbols (#19) 3e92570
• fix: panic on key up/down (#16) 61bc6da
• fix: do not unset the block on render 9821255
• improve docs a902bce 94197fa
• minor performance improvements 837e24a 59a06ee

BREAKING CHANGES:

• refactor(identifier)!: return usize instead of &usize 838668d

v0.11.0

• feat: toggle with identifier 63a5fa0
• feat: implement TreeState select first/last b019567
• feat: implement TreeState arrow key methods c0e4967

BREAKING CHANGE:
TreeState::toggle is now named TreeState::toggle_selected. The toggle method now has an argument for the identifier to be toggled while the new toggle_selected keeps the old behavior of toggling the currently selected entry.
