[wxperl-users] wxTextCtrl very slow on large data files

[Peter G. <pe...@pg...>]

I have a 10MB file which I am trying to load using wxTextCtrl, and I am
using wxPerl.

I have a string $text, which contains the complete text, and the
offending line is:

$self->AppendText($text) ; 


On Windows, the load time is 5 secs.

On Fedora 5, the load time is 15 secs if I set LANG=C
and 85 secs if I set LANG=en_US.UTF-8.

Does anyone know if there is a faster way to load text, using this
widget or a different widget or do I have an intrinsic problem with gtk?


Thanks,

Peter

Yes. I also tried Freeze/Thaw. It didn't help.

Assuming your data is in lines, why not use a Virtual ListCtrl?  Fetch 
the rows from the file that you need as you need them (maybe use IO::All 
or one of the Tie modules).  Do you *have* to have the entire 10 MB file 
loaded into the TextCtrl at once? or could you just load what the user 
is seeing at that point in time?

What I really need is a Virtual TextCtrl. There are two problems with
the ListCtrl:
	a) I can't copy and paste from the control
	b) I sometimes need to highlight part of the line in a 
	different colour. I can do this with the TextCtrl but not with
	the ListCtrl.
