Folks-
I have a simple problem that I want to solve with POE. As I'm looking
at all the various options, I'm getting overwhelmed and need some help
picking out the "best".
I have an ascii logfile (non-growing) that I want to represent in a
GUI (using Tk). My code so far, creates a POE session, and builds the
GUI output window (which is ready to start getting data to add into it).
Now I need to read in the data, parse it into an internal data
structure, then feed that to the GUI for display.
What is the best way to do this? Here are what I think are my 2 best
thoughts so far:
1.) Same session: use Tk's fileevent to get any data that is
available, then parse it, then display it (POE handles the sequencing
so the GUI still functions while the reading-in and parsing is
happening, right?).
2.) Separate sessions: Create a filter that parses the data and use
something like POE::Wheel::FollowTail starting it at the beginning of
the file. Use events between the two sessions to alert the GUI there's
a new internal data structure ready for slapping up on the GUI.
Can the POE experts help me understand why I would want one over the
other?
Are there any better options?
Would it make sense to post this result into the cookbook (I couldn't
find an example of this anywhere)? Any pointers are appreciated.
Thanks
-Craig
