Release Notes

Adanos020/egui_dock (egui_dock)

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 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
