问题 I'm using AvalonEdit in a Microsoft Surface application. It's working great, but I have one problem with folding. There are this small + icons to enable folding. But I don't know how I can register the appropriate contact handlers. Any hints how to do that? 回答1: I'm not sure what you mean by "contact handlers". But you have to supply a folding strategy class based on AbstractFoldingStrategy. However folding strategy to go with most commonly used braces is not in the default AvalonEditor

Making (and keeping) lines readonly in AvalonEdit

问题 What is a robust way of making certain lines readonly in an AvalonEdit control? Users are allowed to change certain method bodies in a C# or VB template file but nothing else. The readonly state per line needs to be kept intact when users add or remove lines, i.e. the readonly blocks below the edited content need to shift up and down accordingly. I'm using AvalonEdit in a WPFHost on winforms. 回答1: You can set textEditor.TextArea.ReadOnlySectionProvider to an implementation of

AvalonEdit: is it possible to highlight this syntax?

问题 I have a simple "language" (similar to template languages and simple markup languages such as BBcode — basically it's just normal text with some variables, tags and similar features) and I want to highlight its syntax. Here is the thing I am stuck with. There are variables, they are enclosed with $ sign ( $var1$ ). I highlight them with this rule: <RuleSet name="VariableSet"> <Rule color="Variable"> \$\S+?\$ </Rule> </RuleSet> Some area around a variable can be surrounded with { } characters.

问题 Actually this was asked on http://community.sharpdevelop.net/forums/p/21949/56153.aspx#56153 but with no answer yet - so I try it here. I'm using Avalon Edit (ICSharpCode.AvalonEdit.dll 4.4.2) in a WPF 4.0 application. I have loaded a text file (~7 MBytes) into the editor. When I apply syntax highlighting and then coping (Control-A and Control-C) the whole text it takes forever (without highlighting it's done in a second) When I break into debugger I get the following callstack (shortened):

Changing default line height in avalon edit

问题 I am writing a custom software using avalon edit and I am looking for a way to make the space (height) between lines bigger. At the moment I am forced to add an empty line every time the user has ended writing a line and wants to write another. I have started looking into the TextView Class where defaultLineHeight seems to be calculated but the only thing I was able to affect is the height of the visual caret but not the content itself. At the moment I am looking at making every pair line

问题 I am writing a movie script editor using AvalonEdit. I extended the DocumentLine class to have a "Type" property, with the value representing either a "Character", "Dialog Line", etc. I would like document lines of a certain type within the script to be written in upper case (character names for example). Is there an extension point within the rendering pipeline that would allow me to fetch a document line and change it's casing ? I tried creating a class that extends
