How to define your own Windows 8 App Theme?
For a school assignement I'm doing some basic research on how Windows 8 Store App Development works. I followed the Hello World tutorial provided by Microsoft. The main themes you can use for the app are Light and Dark (and if I'm correct there's a third one High Contrast or something?), these are defined by MS.
My question is, how can I create my own theme? I'd like to have a basic App Theme with the two main colours defined by me. I think this would be possible, but I haven't found any way of doing it. Looked here on stackoverflow, but didn't find anything helpful (most mention files and such not present in the simple Hello World app).
In short: is it possible to create a theme for you Windows 8 app (mainly choosing the foreground and background colours), comparable to the standard provided Dark and Light themes?
Your best off using a resource dictionary to hold information on your custom styles.
(This is a WPF example, I'm assuming it's the same for apps, if not, let me know).
In your App.xaml , add a merged dictionary, so your App.xaml may look something like this:
<Application.Resources>
<ResourceDictionary>
<ResourceDictionary.MergedDictionaries>
<ResourceDictionary Source="Style/CoreStyle.xaml" />
</ResourceDictionary.MergedDictionaries>
</ResourceDictionary>
</Application.Resources>
You will then need to create a resource dictionary (in my example, I put it in Style/CoreStyle.xaml)
You can then style individual elements in your project, for example, setting a minwidth on a button will look something like:
<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml">
<Style TargetType="{x:Type Button}">
<Setter Property="MinWidth" Value="75" />
</Style>
</ResourceDictionary>
There is a lot more information on the MSDN Styling and Templating Guide which I'd recommend reading.
WP8 default gives you only 2 themes Dark and Light, So If you need to create a theme other than that I think It's not possible.
But if you need to apply theme for a application It's possible, But you have to write all the styles for your theme.
