How would you display an .rtf file?

Would you load it into a TMemo? Or TOpenDialog? Just want to present a
how-to/document to use my app.

KMemo (in KControls) native format is RTF, it has a
KMemo1.LoadfromRTF() (or similar) method.

However, as RTF is such a complicated format, no guarantee it will
know about every RTF tag in there. I have found it pretty good.

Okay DBannon,
   Back to this today and thanks for the links. Can I verify how to
install this into my Laz IDE, I'm a beginner?
   I found the Laz pkg on GetHub via your link to KControls and found
the kcontrolslaz.lpk.  To load it into my Laz IDE would I just create
an empty file with NotePad++ and load and save the contents of
kcontrolslaz.lpk into it and save? Then in Lazarus go to Package -
Install/Uninstall and then Import List?

Make it a PDF  and use OpenDocument

Ok, and how do you do that through code (without a rtf viewer)?

@1HuntnMan
You can install KControl or RichMemo via OPM (Online Package Manager).
Use Package > Online Package Manager

To install KControls, use Online Package Manager:  Package>Online
Package Manager then check and install KControls.

You can also use Richmemo also installed from the online package
manager, but it seems to work better with Windows than with Linux if
that matters for you.  I used it in a project last year and it took
some effort, but was pleased with the result in the end.

As Curt said, the OPM should work fine. TK has made some minor fixes
since the OPM snapshot but I doubt you will see the difference. I tend
to download a zip, unzip into a directory and then look in that dir
with Lazarus -> Packages -> Open package file. ...... Install

That will get you an extra tab, far right, on the components bar. One
of them is KMemo, put a kmemo onto a form.
KMemo.loadfromRTF(AFileName);  I'd suggest that if your RTF file has
RTF things that KMemo cannot handle, you might be in trouble !

Re discussion about PDF, I have a rather lame but function KMemo to
PDF convertor unit in my project. If thats the way you are heading,
its yours as long as you feed back the bugfixes ....

On windows you can check if "rtf"-extension is associated with
something, if so, validate if "something" exists, if so, run
"something" with "rtf" inside a job
else, use what others suggested.
(That way a user has an viewer opened where he is used to)

you can use fpdoc to generate documentation in several different
formats like html, chm, LaTex, Man or pdf. It is used for the
FreePascal docs.
If I needed documentation, I use makeskel, edit that and subsequently
use fpdoc to generate html and display it in ThtmlViewer, CEF or one
of the pdf viewer components. MakeSkel generates a skeleton in XML 
for any unit and has entries for all the identifiers in a unit.
See the documentation for fpdoc.

Once you are done, you can also generate the same docs in other
supported formats. These FreePascal standard tools are often
overlooked.
They are excellent and well structured.
Note that fpdoc can also be used for end-user documentation instead of
the code centered docs that I described above, so also for how-to' s ,
And it is very easy to use,
I recommend it and prefer it above any of the previous suggestions.
Better than working with rtf format...
