FVWM 's Windows buttons (Maximize Minimize ...), Themes

I'm using the F Virtual Window Manager (FVWM). I'm wondering how to customize the window appearance (the theme) to 1. Add a minimize, maximize, and close button, so I have four buttons, arranged like this:

 ---------------------------------------
    |=         (Window Titlebar)       N M X|
    |---------------------------------------|
    |                                       |
    |                                       | 
    |                                       |
    |                                       |
     ---------------------------------------

= is an - button; when clicked on it shows a menu containing move resize raise lower (De)Iconify Delete Close Destroy Identify
N is minimize
M is maximize
X is close

1. How could I set the height of the window title bar? > Answer: The height is govern by the (Window Titlebar) **Font size**. Or; TitleStyle Centered Height 24 #for example
