[wxperl-users] Wx::InputStream

[Scott B. <sc...@go...>]

Hi,

I am writting a patch for POE to work with the Wx event loop and
ran into a small snag. Does Wx currently have the ability to check
for data on a file descriptor? I found Wx::InputStream looking
through the code but I can not find any examples of it's usage.
I looked through the wxwindows site and found:
	wxInputStream is an abstract base class which may not be used directly.

Which it appears this Wx::InputStream is suppose to be an implimention 
of.

Any help with examples or explaination of usage will be
very appreciated.

Cheers,

Scott

Hi Scott,

Mattia might have an answer to this question, but if not, you might try
to ask this question on the wxWindows mailinglist, because it seems it
is more related to the wxWindows API than wxPerl specifically.

But great work you're doing here with the POE patch!

Thanks, I will subscript to that list too :)
Are all the functions/classes available in the perl API?

Thanks! I love POE and Wx looks to be the upcoming GUI for perl.
It looks much nicer than Tk and is portable, what more can you ask!

The main problem I am having right now is POE depends on the
event loop for which it is supporting for IO events such as
knowing when data is available on an FD. In Gtk it uses
Gtk::Gdk->input_add and Gtk::Gdk->input_remove which allows
it to set up events based on weather an FD has stuff waiting or
is ready to recieve data.

I will do some more research and see if there is a way to work-
around the lack of IO events. Thanks a lot for your time.

Cheers,

Scott
