Our libraries create windows pretty much the same way. A call to a window creation function with a few parameters, and, presto, we have a window. When used on the Microsoft Windows OS, they all create similar looking windows because they all allow Windows to do the drawing. That is, they don't use any custom drawing routines. They use the Windows API for all window and control on-screen rendering. Here's how each library's window looks on the Windows platform.

The only difference in these windows is the icon in the title bar. The wxEuphoria icon is probably the wxWidgets application icon. Win32Lib displays the Euphoria program icon.

On the Linux/FreeBSD platform, wxEuphoria renders windows and widgets according to the user's X-windows library. The exciting thing is, the window is drawn with the exact same code as the Windows version!

In Linux/FreeBSD, the user has complete control over the look and feel of the windowing system. One system might look different than another. The good thing is, your wxEuphoria app will work the same in all of them.

As you can see, it's easy to create windows with these Euphoria GUI libraries. In its simplest form, you call the window creation function and provide a few parameters, such as name, size, position, etc.
