No Blocks solution
This solution requires no code blocks as the text is entered directly into the Title properties TextBox of the Designer.
[https://lh4.googleusercontent.com/-RO_nNXm3sw8/UuwFSbeGk6I/AAAAAAAAJ-U/TH1rbpQ9HRE/s1600/noblocks.PNG VIEW THE DESIGNER]
Three blocks solution
This solution uses three blocks to assign the text to the Title bar:
Screen1.Initialize and
set Screen1.Title to "Goodbye World!"

Frink
This brings up an infinitely-rescalable graphic window containing "Goodbye, World" drawn graphically.
All Frink graphics can be written to arbitrary coordinates; Frink will automatically scale and center any drawn graphics to be visible in the window (greatly simplifying programming,) so the exact coordinates used below are rather arbitrary. (This means that if you wrote "Hello World" instead of "Goodbye, World", you could just change that string and everything would still center perfectly.)
The graphics are infinitely-scalable and can be rendered at full quality to any resolution. This program "shows off" by rotating the text by 10 degrees, and also rendering it to a printer (which can include tiling across multiple pages) and rendering to a graphics file. (Frink can automatically render the same graphics object to many image formats, including PNG, JPG, SVG, HTML5 canvas, animated GIF, bitmapped image in memory, and more.)

jq
{{works with|jq|1.4}}
In the following, which generates SVG in a way that can be readily viewed using a web browser, the "Goodbye, World!" text is shaded using a linear gradient.
The approach used here to generate SVG is based on these principles:
- a JSON object is used to specify CSS styles ** this makes it easy to combine default specifications with partial specifications, because in jq, for JSON objects, "+" is defined so that (default + partial) is the combination which gives precedence to the right-hand-side operand;
- for other defaults, the jq "//" operator can be used; thus all SVG parameters can be easily given defaults.
'''Part 1: Generic SVG-related functions'''
# Convert a JSON object to a string suitable for use as a CSS style value
# e.g: "font-size: 40px; text-align: center;" (without the quotation marks)
def to_s:
reduce to_entries[] as $pair (""; . + "\($pair.key): \($pair.value); ");
# Defaults: 100%, 100%
def svg(width; height):
"<svg width='\(width // "100%")' height='\(height // "100%")'
xmlns='http://www.w3.org/2000/svg'>";
# Defaults:
# id: "linearGradient"
# color1: rgb(0,0,0)
# color2: rgb(255,255,255)
def linearGradient(id; color1; color2):
"<defs>
<linearGradient id='\(id//"linearGradient")' x1='0%' y1='0%' x2='100%' y2='0%'>
<stop offset='0%' style='stop-color:\(color1//"rgb(0,0,0)");stop-opacity:1' />
<stop offset='100%' style='stop-color:\(color2//"rgb(255,255,255)");stop-opacity:1' />
</linearGradient>
</defs>";
# input: the text string
# "style" should be a JSON object (see for example the default ($dstyle));
# the style actually used is (default + style), i.e. whatever is specified in "style" wins.
# Defaults:
# x: 0
# y: 0
def text(x; y; style):
. as $in
| {"font-size": "40px", "text-align": "center", "text-anchor": "left", "fill": "black"} as $dstyle

return rc;
}
};
Build rules are ''jsish -c'' preprocessor, query ''jsish'' for C compile time flags, compile the C, load the module into jsish via ''require''.
prompt$ make -B -f Makefile.jsc hello
jsish -c JsiAgarGUI.jsc
gcc `jsish -c -cflags true JsiAgarGUI.so` `agar-config --cflags --libs`
jsish -e 'require("JsiAgarGUI"); JsiAgarGUI.alert(" Goodbye, World! ");'
And a window pops up with the message and an Ok button.
First command ''jsish -c'' runs a JSI to C preprocessor, generating a ''.h'' C source file.
For the second step, gcc is called with the output of a ''jsish -c -cflags true'' query, libagar runtime is linked in with more substitution for Agar compiler commands. The query output will be something like (this is site local, details will change per machine setup):

This tells the compiler to link with the UI library, the file name of the implementation code, and to output a program named "Hello".
N/t/roff
Whether the output is graphical or text depends largely the compiler with which the /.ROFF/ source code below is compiled. If it is compiled with an Nroff compiler, its output is comparable to that of a typewriter. Therefore, output from Nroff is typically seen on a text terminal. If it is compiled with a Troff compiler, its output is comparable to that of a typesetter. Therefore, output from Troff is typically seen on a PostScript or PDF output using a document viewer. Furthermore, output from Troff is also usually seen on paper, so that may count as graphical as well. In conclusion, although the code is compatible with both Nroff and Troff, it should be compiled using Troff to guarantee graphical output.
Because /.ROFF/ is a document formatting language in and of itself, it is extremely likely that a user of /.ROFF/ will be typing mostly textual content in a natural language. Therefore, there are no special routines or procedures to be called to output normal text, as all text will get formatted onto paper automatically.

Seed7 does not work with an event handling function like gtk_main(). The progam stays in control and does not depend on callbacks. The graphic library manages redraw, keyboard and mouse events. The contents of a window are automatically restored when it is uncovered. It is possible to copy areas from a window even when the area is currently covered or off screen.
