Changelog

All notable changes to myTk are documented here.

[0.10.11] - 2026-02-26

Fixed

  • TabularData._normalize_record() no longer mutates required_fields on every insert
  • TabularData.record() and update_record() now correctly look up records by UUID objects (not just strings)
  • SimpleDialog key shortcuts (<Return>, <Escape>) now assigned after buttons are created, not before
  • Several bugs fixed in entries.py: Entry binding order, FormattedEntry display initialisation, FormattedEntry crash on non-numeric input, FormattedEntry.value setter coercion, CellEntry focusout reference, LabelledEntry value passthrough
  • NumericEntry consolidated into IntEntry; NumericEntry kept as alias for backwards compatibility

Added

  • formatted_entry_app.py example demonstrating FormattedEntry with various format strings

[0.10.10] - 2026-02-25

Changed

  • CanvasView.is_disabled and Dialog.is_disabled now propagate disabled/enabled state to all descendant widgets

[0.10.9] - 2026-02-25

Changed

  • View.is_disabled now recursively propagates the disabled/enabled state to all descendant widgets (same behaviour as Box)
  • Refactored _propagate_disabled() helper from Box into Base to avoid duplication

[0.10.8] - 2026-02-25

Changed

  • Box.is_disabled now recursively propagates the disabled/enabled state to all descendant widgets; disabling a Box grays out all contained controls automatically

[0.10.7] - 2026-02-25

Added

  • position parameter on App, Window, and Dialog for named screen placement: "center", "top-left", "top-right", "bottom-left", "bottom-right"
  • EventCapable._bind_destroy_cancel(): automatically cancels all tracked after() tasks when a widget is destroyed; called by grid_into/pack_into/place_into as a safety net; convention is to also call it at the end of create_widget() overrides
  • _BaseWidget._bind_destroy_cancel(): no-op fallback so subclasses can safely call it regardless of MRO
  • App.__init__ binds <Destroy> on root to cancel all pending Tcl after/after_idle events via after info

Fixed

  • apply_window_position deferred callback no longer causes invalid command name errors when the widget is destroyed before the after_idle fires

[0.10.6] - 2026-02-24

Fixed

  • XYPlot.create_widget was assigning to self.first_axis which is a read-only computed property, causing AttributeError via Bindable.__setattr__; fix calls self.figure.add_subplot() directly (same pattern as Histogram)

[0.10.5] - 2026-02-24

Fixed

  • Histogram.create_widget never added a subplot, leaving first_axis as None and causing a crash in clear_plot() / update_plot() when the histogram was updated (e.g. in MicroscopeApp)

[0.10.4] - 2026-02-24

Fixed

  • App(no_window=True) now actually withdraws the main window — the parameter was previously accepted but silently ignored
  • Removed stale no_window=True from envtest.py; tests need a visible window and the parameter had no effect before this fix

[0.10.3] - 2026-02-18

Added

  • progressbar_app.py example demonstrating three ways to update a ProgressBar: direct value assignment, step(), and background thread via schedule_on_main_thread()

[0.10.2] - 2026-02-18

Added

  • bring_to_front=True option on App — uses osascript on macOS to reliably activate the process window, overcoming editor focus reclaim

[0.10.1] - 2026-02-17

Fixed

  • ProgressBar and ProgressWindow fully implemented and tested
  • ProgressBar.step() now updates value_variable directly (bypasses unreliable ttk.Progressbar.step() sync)
  • ProgressWindow exposes self.progress_bar after run()
  • Notification handlers guard against stale observers with try/except around winfo_exists()

[0.9.15] - 2026-02-14

Added

  • Configurable mixin and ConfigModel class for declarative property management with automatic validation and dialog generation (ConfigurableNumericProperty, ConfigurableStringProperty, ConfigurationDialog)

Fixed

  • Mutation-during-iteration bug in after_cancel_all()
  • Entry.__init__ was resetting initial value to empty string
  • Wildcard re-export and missing partial import
  • Hanging test in testCustomDialogs
  • Dead code, hardcoded path, and optional cv2 import
  • Modernized project structure to current Python packaging standards

[0.9.12] - 2025-xx-xx

Added

  • schedule_on_main_thread() on App for safely dispatching work from background threads
  • is_main_thread() utility function
