Release Notes

Adanos020/egui_dock (egui_dock)

v0.18.0

Breaking changes

• Upgraded to egui 0.33 (#​293)

Changed

• Node separators are always clamped between their bounds. (#​289)

v0.17.0

Breaking changes

• From (#​272):
  • Nodes underlying data has been split up into the LeafNode and SplitNode types, meaning that any match
    statements carried out on a node now needs to account for this.
• Upgraded to egui 0.32 (#​280)

Changed

• From (#​272):
  • Tree::set_active_tab now takes impl Into<NodeIndex> and impl Into<TabIndex> to make use slightly easier.
  • Surface now implements Index<NodeIndex>/IndexMut<NodeIndex> which tries to access the surfaces node tree and
    the node at the index. This will always panic when used on an empty surface as they do not have a node tree nor
    nodes.

Added

• From (#​272):
  • DockState::iter_leaves and DockState::iter_leaves_mut - can be used to more efficiently iterate over leaf
    nodes without needing to "unwrap" them from the Node enum.
  • DockState::find_tab_from/Tree::find_tab_from - a more generalized version of the existing find_tab methods
    which doesn't require the tab type to implement PartialEq.
  • New type LeafNode which contains leaf node data and has the following methods:
    • new,
    • set_active_tab,
    • set_rect,
    • rect,
    • len,
    • is_empty,
    • tabs,
    • tabs_mut,
    • append_tab,
    • insert_tab,
    • remove_tab,
    • retain_tabs,
    • active_focused.
  • New type SplitNode which contains data about node splits and has the following methods:
    • new,
    • set_rect,
    • rect.
  • Node::get_leaf/Node::get_leaf_mut - an alternative way of trying to access leaf data in a node.
• TabBarStyle now has two new fields: inner_margin and
  spacing. (#​270)

Fixed

• DockState::retain_tabs no longer deletes the main surface if it ends up
  empty (#​277).
• From #​275:
  • {DockState,Tree}::remove_leaf now removes unused empty node`s at the back of the tree.
  • {DockState,Tree}::retain_tabs no longer deletes leaf nodes it shouldn't delete.

v0.16.0

Breaking changes

• Upgraded to egui 0.31.

v0.15.0

Changed

• From (#​237):
  • Each leaf can now be collapsed / closed individually. They are introduced as additional tab bar controls.
  • Undocked windows are now more compact. The original undocked window controls are now accessible as "secondary
    buttons" from the tab bar.
    • By default, the secondary buttons are activated from primary buttons either by holding the Shift
      key while clicking on them, or from a context menu by right-clicking them.
  • A number of tooltip hints are on by default as guides to the new behavior, but they can be disabled.
  • There has been an overhaul to the internal codebase to support the new features.

Added

• From (#​237):
  • DockArea::show_leaf_close_all_buttons – shows a close all button which closes all open tabs in a leaf.
  • DockArea::show_leaf_collapse_buttons – shows a collapsing button which collapses a leaf (no longer collapsing a
    window).
  • DockArea::show_secondary_button_hint – sets whether tooltip hints are shown for secondary buttons on tab bars.
  • DockArea::show_leaf_collapse_buttons – shows a collapsing button which collapses a leaf (no longer collapsing a
    window).
  • DockArea::secondary_button_on_modifier – sets whether the secondary buttons on tab bars are activated by the
    modifier key.
  • DockArea::secondary_button_context_menu – sets whether the secondary buttons on tab bars are activated from a
    context value by right-clicking primary buttons.
  • Added the following translations:
    • LeafTranslations::close_all_button
    • LeafTranslations::close_all_button_menu_hint
    • LeafTranslations::close_all_button_modifier_hint
    • LeafTranslations::close_all_button_modifier_menu_hint
    • LeafTranslations::close_all_button_disabled_tooltip
    • LeafTranslations::minimize_button
    • LeafTranslations::minimize_button_menu_hint
    • LeafTranslations::minimize_button_modifier_hint
    • LeafTranslations::minimize_button_modifier_menu_hint
  • Node::is_collapsed – returns whether the Node is collapsed.
  • Node::collapsed_leaf_count – returns the number of collapsed layers of leaf subnodes.
  • Node::set_collapsed – set the collapsing state of the Node.
  • Node::set_collapsed_leaf_count – sets the number of collapsed layers of leaf subnodes.
  • WindowState::minimized field – records whether a window is minimized.
  • WindowState::expanded_height field – records the height of the window before it was fully collapsed.
  • Added style configuration for the two buttons:
    • ButtonsStyle::{close_all_tabs, collapse_tabs, minimize_window}_color
    • ButtonsStyle::{close_all_tabs, collapse_tabs, minimize_window}_active_color
    • ButtonsStyle::{close_all_tabs, collapse_tabs, minimize_window}_bg_fill
    • ButtonsStyle::{close_all_tabs, collapse_tabs, minimize_window}_border_color
    • ButtonsStyle::close_all_tabs_disabled_color
    • Style::TAB_CLOSE_ALL_BUTTON_SIZE
    • Style::TAB_CLOSE_ALL_SIZE
    • Style::TAB_COLLAPSE_BUTTON_SIZE
    • Style::TAB_COLLAPSE_ARROW_SIZE
    • Style::TAB_EXPAND_BUTTON_SIZE
    • Style::TAB_EXPAND_ARROW_SIZE

Breaking changes

• From (#​237):
  • Renamed Translations::WindowTranslations to Translations::LeafTranslations.
  • Renamed WindowTranslations::close_button_tooltip to LeafTranslations::close_button_disabled_tooltip.
  • Translations::LeafTranslations now requires more fields to be constructed (see Added section).
• Upgraded to egui 0.30.

Deprecated

• From (#​237):
  • DockArea::show_window_close_buttons – no longer has any effect; consider using
    DockArea::show_leaf_close_all_buttons
    instead.
  • DockArea::show_window_collapse_buttons – no longer has any effect; consider using
    DockArea::show_leaf_collapse_buttons
    instead.
