Question

In Win32 API, function SetWindowPos provided an easy way to move and resize window at once.

However, in WPF class Window doesn’t have a method like SetWindowPos. So I must code like the following:

        this.Left += e.HorizontalChange;
        this.Top += e.VerticalChange;
        this.Width = newWidth;
        this.Height = newHeight;

Of course, it works well, but it’s not simple. And it looks dirty.

How can i move a window and resize at once?

Is there an API?

Answer 1

You could wrap your code in a helper method. Just like this:

public static class WindowExtensions {
    public static void MoveAndResize( this Window value, double horizontalChange, double verticalChange, double width, double height ) {
        value.Left += horizontalChange;
        value.Top += verticalChange;
        value.Width = width;
        value.Height = height;
    }
}

So your calling code looks like this:

this.MoveAndResize( 10, 10, 1024, 768 );

I’ve left off namespace and using declaration, keep that in mind when copying.

Edit:

You could also use the API. Personally I stick with the managed code unless I really need to use the API. But that is up to you.
