Using the X11 & plotutil libraries is not part of any of the original UNESCO/IFIP [[ALGOL 68]]

reports. As at December 2008 only [[ALGOL 68G]] comes with these built in.

=={{header|Common Lisp}}==

This example uses CLX, which is the de facto standard X11 library for Common Lisp. CLX is not a binding to Xlib; it is a Lisp library implementing the X11 protocol.

Graphical User Interface Support Script is really a language for operating a computer, rather than programming one, so we cannot do this via X11 libraries. The example uses leafpad for our open window, and the box symbols to enclose our text:

=={{header|Icon}} and {{header|Unicon}}==

Icon and Unicon provide a portable graphics implementation that does not rely upon a toolkit. The intent is to be platform independent and the same code runs on multiple platforms without change and producing results with only minor variations. Icon and Unicon graphics are implemented in X-Windows as well as MS-Windows and others. There are additional 3D graphics capabilities implemented using opengl.

W1 := open("X-Window","g","size=250,250","bg=black","fg=red") | stop("unable to open window")

FillRectangle(W1,50,50,150,150)

Ao for this task we use the M2000 way to make a form and do something on it.

=={{header|Racket}}==

Using Racket's GUI which is implemented using gtk. It's not low level, but OTOH it works on Windows and OS X too.

(send dc set-text-foreground "blue")

(send dc draw-text "Don't Panic!" 0 0))])

There is not yet a X11 library in Raku but we can write the minimal C mappings for this task.

=={{header|Standard ML}}==

Works with PolyML

val dp = XOpenDisplay "" ;

val w = XCreateSimpleWindow (RootWindow dp) origin (Area {x=0,y=0,w=400,h=300}) 3 0 0xffffff ;

XFlush dp ;

XDrawString w (DefaultGC dp) (XPoint {x=10,y=50}) "Hello World!" ;

=={{header|Tcl}}==

===Low level interface===

{{libheader|critcl}}

package require critcl

const char *str = Tcl_GetStringFromObj(msg, &len);

XDrawString(d, (Window)w, gc, x, y, str, len);

Note that this only does enough for this demo. A full adaptation is too long for RosettaCode...

This could then be used like this:

XOpenDisplay {}

}

XDestroyWindow $w

===Higher level interface===

Just because there is a low level package does not mean that it is pleasant to use from Tcl code. Therefore this second package wraps it up inside a higher-level package that provides a more natural way of interacting.

<br>

{{works with|Tcl|8.6}} or {{libheader|TclOO}}

package provide x11 1

}

}

This script puts the pieces together to carry out the details of the task.

# With a display connection open, create and map a window

$w destroy

Improving this by adding more sophisticated event handling and more window methods is left as an exercise.

<br>

As it's not currently possible for Wren-cli to access Xlib directly, we embed a Wren script in a C application to complete this task.

var KeyPressMask = 1 << 0

if (e.eventType == KeyPress) break

}

<br>

We now embed this Wren script in the following C program, compile and run it.

#include <stdlib.h>

#include <string.h>

free(script);

return 0;
