AvalonEdit Samples

Implements sample projects to demo the AvalonEdit control with extensions (see also Dirkster99/AvalonEditHighlightingThemes).

Demo Projects

00 MVVMDemo

The 00 MVVMDemo project gives a simple MVVM/WPF demo application that implements some simple features like:

1. Text loading
2. Editing (Copy, Paste, Cut, Undo, Redo), and
3. Highlighting.

This demo project is the base project for all other sample projects in this repository and Dirkster99/AvalonEditHighlightingThemes.

10 Scale Font Demo

The 10 ScaleFontDemo project shows how the display font can be scalled with interactive means like

• the Scale up/scale down (two finger) gesture on your touch-pad, or
• Control Key and mouse wheel to zoom text size in or out.

14 Scale Font Demo

The 14 ScaleFontDemo project implements the 10 ScaleFontDemo project and adds a custom scalling control from the UnitComboLib project.

• Use The UnitComboBox in the left/lower corner of the MainWindow to change the FontSize according to:
  • Points or
  • Percentage scales.

17 Switch Demo

The 17_SwitchDemo project is a small prototype app that reviews how AvalonEdit will cope if we use 2 different Document bindings and switch between them whenever we like to. I needed this feature because I wanted to kind of overlay 2 different displays when showing highlighting for different lines (comparing) or editing the text when a user would wish to re-align different sections of text in Ähnlich.

20 Highlight Current Line Renderer

The 20_HighlightCurrentLineRenderer project shows how the currently edit line can be highlighted with a current HighlightCurrentLineBackgroundRenderer extension.

30 CursorPosition Edit Status

The 30_CursorPosition_Edit_Status

project demonstrates a status display in the lower right corner of the status bar (when a document is loaded).

Items shown are:

• Cursor position (Ln and Col)
• OverstrikeMode (whether user overwrites available content with next character typed or not)
• Encoding (UTF 8, Western European (Windows), etc) - See also Tool Tip of this element

40 View Options

The 40_View_Options

project demonstrates editing options, such as:

• toogle Word Wrap
• Toggle Display of Line Numbers
• Toggle display of white spaces, such as, End of Line, Space character, and Tab character

55 AE Commands

The 55_AE_Commands project implements the basic features of the 00_MVVMDemo project in a seperate control library called TextEditLib and adds the followinf features:

• Text Folding for C#, Java, XML, XAML
• Advanced Command Bindings via ContextMenu (Collapse All Text Folds, Expand All Folds)
• Integration of standard AvalonEdit commands, such as, Replace Tabs with Spaces etc.

88 MVVM ThemedDemo

The 88 MVVM ThemedDemo project shows how syntax highlighting can be integrated into WPF Theming without using custom highlighting definitions per theme.

This solution is just an intermediate step from the 00 MVVMDemo solution to give you an understanding of what might be necessary to add WPF theming to an existing MVVM application. This demo solution also shows how bad it is to use highlighting definitions for a Light WPF theme on a Dark WPF theme and vice versa.

Please refer to Dirkster99/AvalonEditHighlightingThemes for an improved solution that coordinates:

1. Dark/Light/True Blue WPF themes
2. with an appropriate Syntax Highlighting Theme.
