I want to create 5 buttons in a title bar of a window using this way: http://delphihaven.wordpress.com/2010/04/19/setting-up-a-custom-titlebar/
Firefox has one button (the same for Opera):
Not maximized window
Maximized window
How to make such buttons for my purpose? Rounded/curved, with bevels, with/without an image, with/without a gradient. Are there similar components? Do I need to make it manually? If so, then how? If it's not a button then what is it? Is there an alternative for it?
