# AvalonDock
Support this project with a :star: -report an issue, or even better, place a pull request :mailbox: :blush:
My projects Edi, Aehnlich, and [many others](https://github.com/search?p=4&q=%22dirkster.avalondock%22&type=Code) (open source or commercial) are powered by this project.
AvalonDock is a WPF Document and Tool Window layout container that is used to arrange documents
and tool windows in similar ways than many well known IDEs, such as, Eclipse, Visual Studio,
PhotoShop and so forth. Here are some CodeProject articles:
* [AvalonDock [2.0] Tutorial Part 1 - Adding a Tool Window](https://www.codeproject.com/Articles/483507/AvalonDock-Tutorial-Part-Adding-a-Tool-Windo)
* [AvalonDock [2.0] Tutorial Part 2 - Adding a Start Page](https://www.codeproject.com/Articles/483533/AvalonDock-Tutorial-Part-Adding-a-Start-Page)
* [AvalonDock [2.0] Tutorial Part 3 - AvalonEdit in AvalonDock](https://www.codeproject.com/Articles/570313/AvalonDock-Tutorial-Part-AvalonEdit-in-Avalo)
* [AvalonDock [2.0] Tutorial Part 4 - Integrating AvalonEdit Options](https://www.codeproject.com/Articles/570324/AvalonDock-Tutorial-Part-Integrating-AvalonE)
* [AvalonDock [2.0] Tutorial Part 5 - Load/Save Layout with De-Referenced DockingManager](https://www.codeproject.com/Articles/719143/AvalonDock-Tutorial-Part-Load-Save-Layout)
This repository contains **additional bug fixes and a feature added** fork for:
xceedsoftware/wpftoolkit version **3.2-3.6**. Version 4.0 and later are developed indepentently, which is why this library (version 4.0 and later) uses the namespaces and library names that were used in AvalonDock 2.0 and earlier versions. But most importantly, the usage of this AvalonDock project remains free for both, commercial and open source users.
There is also an open source repository https://github.com/dotnetprojects/WpfExtendedToolkit with a fixed and stable version of all other (other than AvalonDock) components from the WPFToolKit.
Be sure to checkout the Wiki for more details.
## Building AvalonDock from Source
This project supports multitargeting frameworks (NetCore 3 and .Net 4). This means that it requires
Visual Studio Community 2019 or better to build.
# Feature Added - Dark and Light VS 2013 Theme
Please review the Project Wiki to see more demo screenshots.
All screenshots below are from the MLib based VS 2013 Dark (Accent Color Gold)/Light (Accent Color Blue) theme on Windows 10. Similar theming results should be possible with other theming libraries since the implementation follow these guidelines.
The Docking Buttons are [defined in XAML](https://github.com/Dirkster99/AvalonDock/wiki/OverlayWindow), which ensures a good looking image on all resolutions, even 4K or 8K, and enables us to color theme consistently with the Window 10 Accent Color.
Description
Dark
Light
Dock Document
Dock Document
Dock Tool Window
Document
Tool Window
## Theming
Using the *AvalonDock.Themes.VS2013* theme is very easy with *Dark* and *Light* themes.
Just load *Light* or *Dark* brush resources in you resource dictionary to take advantage of existing definitions.
```XAML
```
```XAML
```
These definitions do not theme all controls used within this library. You should use a standard theming library, such as:
- [MahApps.Metro](https://github.com/MahApps/MahApps.Metro),
- [MLib](https://github.com/Dirkster99/MLib), or
- [MUI](https://github.com/firstfloorsoftware/mui)
to also theme standard elements, such as, button and textblock etc.
