Hex editor and FXRuby ?

[Noel Cuillandre]

Anyone know to make a hex editor in FXRuby ?
My problem is that i have tried and not succeeded to display hex bytes
from a 10Ko file in a FXtext in a reasonnable time !
Any clue ?
thanks

IIRC there exists a library where you can memory map a file, this way you
can be looking at a small window, say 2kbytes of a huge file 30gbytes.
Though I don't know any urls to this module.

When one attempts to move the cursor outside the window, then you just
slide the window to the new position.

FXtext should display a Megabyte in reasonable time.
Measure where you spend the time. I found that you must always add as
much text as possible at once. Appending text ist terrible slow.

You're right, Lothar, appending text is the way i used to add data to
the FXText, Simon Strandgaard has given another method using memory map
file. I will try this.
Thanks again
