Window creation/X11: Difference between revisions

{{field attention|Common Lisp|X11|This example was written in near-total ignorance of X11 by consulting the [http://www.cliki.net/CLX%20Manual CLX manual] to find equivalents for the parts of the C example. It was also only tested with [[Mac OS X]] X11, which is not exactly normal. — (ps: Testing on Linux (Fedora 21/x86-64), it seems to display black-on-black, so the "Hello" is lost.). Testing new code changes (i.e. adding background and foreground) should fix the issue, it was tested on LinuxMint 17.1/x86-64}}
