Base class for margins. Margins don't have to derive from this class, it just helps maintaining a reference to the TextView and the TextDocument. AbstractMargin derives from FrameworkElement, so if you don't want to handle visual children and rendering on your own, choose another base class for your margin!

Helper class with caret-related methods.

Contains classes for handling weak events on the Caret class.

Margin for use with the text area. A vertical dotted line to separate the line numbers from the text view.

Wraps exceptions that occur during drag'n'drop. Exceptions during drag'n'drop might get swallowed by WPF/COM, so AvalonEdit catches them and re-throws them later wrapped in a DragDropException.

Determines whether the document can be modified.

A set of input bindings and event handlers for the text area.

Margin showing line numbers.

Handles the Caret.PositionChanged event.

Rectangular selection ("box selection").

Base class for selections.

Represents a selected segment.

Control that wraps a TextView and adds support for user input and the caret.

Contains the predefined input handlers.

Default-implementation of ITextAreaInputHandler.

Stacked input handler. Uses OnEvent-methods instead of registering event handlers to ensure that the events are handled in the correct order.

EventArgs with text.

Implementation for IReadOnlySectionProvider that stores the segments in a TextSegmentCollection<(Of <(<'T>)>)>.
