* Refactored ProcessKey to use public methods for case logic
* Added KeyBinding class
* Refactored key binding to split key->command from command->implementation
This reduces duplication and simplifies the API
* Finishing key bindings implementation in ListView.
* Adding more unit tests to the ListView.
* Added key bindings to the Button and more features.
* Replaces Action for Func<KeyEvent, bool> on CommandImplementations.
* Allowing commands to have any number of arguments.
* Implementing key bindings on Checkbox view.
* Added test for changing HotKey in Button and made ReplaceKeyBinding protected
* Changed `CommandImplementations` to `Func<KeyEvent, bool>` to better understand current command implementations
* Implementing key bindings in ComboBox.
* Renamed Command keys and fixed ComboBox issues:
- Fixed pressing Esc in ListAndCombos scenario without selecting cause an array out of bounds error
- Changed the Esc key in ComboBox to also collapse the list selection
- Added bool return to public virtual method Expand and Collapse (this is a breaking change)
* Implementing key bindings in DateField.
* Organizing some things.
* Implementing key bindings on TimeField.
* No key bindings on FrameView.
* Added keybinding support to TreeView
* Added mouse support and more features.
* Updating NuGet packages.
* Putting text on the same line.
* Changing function command to Func<bool>.
* Added a read only Position, CursorPosition properties and events.
* Keybindings for GraphView
* Added a stream argument to ApplyEdits to only save the edits.
* Implementing key bindings on the HexView.
* Added MenuOpened event and others bug fixes.
* Fixing typo.
* Unifying constructors initializations.
* Implementing keybindings in the Menu.
* Removing unnecessary variable.
* Implementing keybindings in RadioGroup view.
* Changing Home to TopHome and End to BottomEnd.
* Implementing keybindings in the ScrollView.
* Changing the PageLeft and PageRight keybindings.
* Fixing PageLeft and RightPage.
* Removing CleanUp command.
* Key bindings for TabView
* Keybindings for TableView
* Fixed unit tests for PageDown to correctly assign input focus to the TableView
* Fixes the CalculateLeftColumn method avoiding jump two columns on forward moving.
* Fixes #1525. Gives the same backspace behavior as TextView.
* Changes kill-to-start key to work on Linux too.
* Fixes SelectedStart, SelectedText and some cleaning.
* Implementing keybindings in TextField.
* Updated command names and merged as discussed with @BDisp
- Merged LeftItem and LeftChar to Left (same for Right).
- Also renamed Kill to Cut
- Added ScrollLeft / ScrollRight (and renamed ScrollLineUp to just ScrollUp
* Renamed Command.InsertChar to ToggleOverwriteMode and added Enable/Disable
* Removed 'Mode' suffix from toggle overwrite
* Allows navigation to outside a TextView if IsMdiContainer is true.
* Implementing keybindings in Toplevel.
* Fixing null reference exception.
* Changing to keys instances events instead static.
* Transferring the events to the Toplevel.
* Implementing keybindings in TextView.
* Removing static from the QuitKeyChanged and adding unit test.
* Replacing Added with the Initialized event.
* Ignore control characters and other special keys.
* Changing InvokeKeybindings to return Nullable bool and added two more keys to the Toplevel.
* Implementing keybindings in Autocomplete. I had to derive from View.
* Added keybindings menu item to UICatalog
* Added ClearBinding
* Implementing IAutocomplete, abstract Autocomplete and derived TextViewAutocomplete.
* Implementing keybindings in the TextValidateProvider
* Add keybinding to CellActivationKey.
* Fixing some formats.
* Add ObjectActivationKey to the keybindings.
* Made it much easier to implement abstract base `Autocomplete` in other views by moving methods up out of `TextViewAutocomplete` implementation
* Allowing Autocomplete to popup inside or outside the container.
* Fixes the cursor not being showing if the text length is equal to the view width.
* A unit test to prove the 4df5897.
* Removed unused method `GetCursorPosition` from Autocomplete
* Trimmed down implementation specific methods from IAutocomplete
* Fixed xmldoc comment tag
* Format Autocomplete on multiline and fixes wrap settings.
* Adding keys from a to z to avoid the Key.Space on ToString.
* Fixes the vertical position outside the container.
* Adding more key unit tests.
* Changing comment to upper case and proving that doesn't will breaking nothing.
* Replaces Pos.Bottom to Pos.AnchorEnd.
* Fixes popup on resizing.
* Should only using the Pos.Bottom to position outside the view.
* Fixes #1584
* Fixes https://github.com/migueldeicaza/gui.cs/issues/1584#issuecomment-1027987475
* Fixes some bugs with SelectedItem.
* Command must also return a nullable bool.
* Ensures updating the ComboBox text on leaving the control.
* Only with the nullable bool was possible to make the MoveUp and the MoveDown working.
* Added logging of which scenario failed in test
