Hi all,
I am using QTextEdit to display log text files, just like the Unix command tail -f.
My current implementation just displays the last 5 lines and then follows the growing
log file, displaying lines as they come.
Now, I am asked to make QTextEdit display the whole file when the user opens a file.
A log file can be very large. I tested it with a 2mbyte file, and inserting data to QTextEdit
caused the GUI to freeze for almost 1 minute.
This is not acceptable, and I am looking for a solution. I have the following questions:
-) what is the fastest way to insert lots of text into QTextEdit?
-) should I go to the route of implementing my own QTextDisplay? If so,
should I use QAbstractScrollArea as class base? Any pointer to how to use it?
Thanks in advance,
JM

Personally I didn't face this issue before, but I suggest to use
QTextBrowser because it optimized for text displaying or you can
use QListWidget instead (I prefer it) thus it's easy to add tons
of items as you want.

but I found this library which could be interesting for fixing
logging issue:
