DockPanel Suite: Theme Reloaded

I blogged about DPS theming a few times, aiming to demonstrate how we ported VS2012 Light theme in, how the related API was refactored, and how themes became separate NuGet packages. But I never expected that today I can blog about two new themes and potentially more from you. So let’s get started.

Visual Studio 2010

Interestingly that Microsoft gave up Windows Forms and built Visual Studio 2010 on WPF. That instantly led to a brand new theme being shipped,

This is a blue theme, which many people easily got bored with.

Visual Studio Color Theme Manager

So an extension was soon released by Microsoft for end users to design their own themes,

Visual Studio 2012 Themes

Thus, when Microsoft designed Visual Studio 2012, they came across the idea to ship by default, a light theme, as well as a dark theme.

Due to the community feedback, in a later Update, the blue theme was also added back. Color Theme Manager is also provided.

Later Visual Studio Releases

Visual Studio 2013 and 2015 do ship all three themes by default (Light, Dark, and Blue), and they also have Color Theme Manager extensions.

DockPanel Suite’s Old Themes

If you are familiar with our previous code base (2.10 for example), you know that we use DockPanelSkin to store the colors used in each themes. It was an old design mainly for Visual Studio 2003/2005 themes. So using it to help render Visual Studio 2012 Light and 2013 Blue themes is painful.

New Theme Design

As Color Theme Manager exposes the internals of Visual Studio themes as color palette, it is in fact quite easy to design a few new classes in DPS to map the palette and the colors. So in 2.11 release, I finally have some time to finish it.

DockPanelSkin now has a ColorPalette property, which in turn contains further properties to map to each of the core colors of a theme. So to create a new theme like VS2012DarkTheme, we just need to change the colors to the values provided by Color Theme Manager. Yes, it is just that simple. And now we have a full family of VS2012 themes (Light, Dark, and Blue).

The testing of new themes also revealed a few minor bugs that we neglected in the past. For example, the last tab on tool window strip does not have a separator unless it is active. They are now fixed.

However, one price we have to pay is that VS2013 Blue theme is now broken. I will see if I can fix it before we ship 2.11 final release. But you can of course switch to VS2012 Blue theme which is more mature.

So now if you want to create a new theme, you can follow this guide,

New Alpha Builds

2.11 Alpha 4 is now available for you to test out the new themes.

Stay tuned.
