Use system color resources

- [Instructor] In the Microsoft Windows operating systems…there's a standard set of colors that are used…throughout the operating system…and are used to draw certain parts…of the windows that the user sees.…So if you want parts of your application…to be consistent with the same colors…that are used inside the operating system,…you can use a set of pre-defined system colors in WPF.…Here's how that works.…Hold down the spacebar and move this over a bit.…Selected my ellipse, I want to fill this ellipse…with a solider color brush.…So I go to Properties, go to Brush,…click on the Fill property, click on Solid Color Brush.…

Now I want to set the color of that brush…based on the system color.…So go look at the Color Resources tab,…and you'll see that I have my three…local resources that I've defined here,…and below that is a set of standard colors.…So if you want your application to match…the Gradient Active Caption Color Key, use this item.…I'll choose the Desktop Color Key.…And then I'll go over to the rectangle,…and I'll do a similar action.…
