pncconf

Pncconf can only be opened and save properly with ubuntu 8.04.

Pncconf's combo boxes functions are extremely complicated.

Can you give me a sample for what you would like to put in yours?
do you want two levels of drop downs like pncconf or is one enough?

Chris M

By two level I meant a dropdown list inside a drop down list AKA treeview.
simple combo boxes oly have a single list of choices.

I never could find a tutorial for a treeview combobox so pieced it together from related stuff.

Here are some sample files I used to figure out how to have a treeview in combo boxes.
There are also two other files to show a treeview not in a combobox and a fairly plain combobox.
Run these from a terminal - most have debug output.

Hope that helps. I can show you a link to help with figuring out tree iters if you need it.

I will take the opportunity to ask: how do you develop pncconf in practice? I've opened the pncconf.glade file in glade-3.8.1, and it seems to work, but it takes something like 15 minutes! Do you keep it always open?

Through some command-line-fu I've managed to split the .glade file into five separate files each containing one of the top-level windows (window1, helpwindow, openloopdialog, scaledialog, and tunedialog). Window1 still takes forever to open, but the others are now quick. I'm a complete beginner at glade, but I believe that it is possible to split a project over several files?

I'm also new to Python (I believe I could call myself an expert C programmer though and I'm also well-versed in object oriented programming and design).

So here's a Python specific question: in your Data class, you seem to treat self as a Python Dictionary. For example:Does this create an "invisible" dictionary variable as an instance variable of self? Or what's going on there? (I've tried to google it but no luck.)

Well, anyway... perhaps I can be of some help adding more structure (and a more object oriented approach) to PnCConf, if you want me to?

Well I'm a self taught programmer. PNCconf was my first Python program.
It is based on stepconf which Jeff Eppler wrote (he is a programmer).
I hacked my way to a functioning program. It's ugly and complicated and inconsistently written without a clear plan.

The particular line you quoted is part of an initializing sequence of data. (and it's a class of data as well)
Here is a very shortened version:

class Data:
def __init__(self):

for temp in("x","y","z","a","s"):

self[temp+"drivertype"]= "custom"
self[temp+"steprev"]= 200
self[temp+"microstep"]= 5

def __getitem__(self, item):
return getattr(self, item)
def __setitem__(self, item, value):
return setattr(self, item, value)

The two special methods allow self[ ] to work.
In this case I am using them to allow me to use a for loop to initialize common data to all the axes.

If you would like to hack on PNCconf - that would be great.

I would like to break it up a bit into a couple of files.
There is dead code to remove ( the never-could-get-it-to-work-happily test panel)
The HAL file printing should be broken out of the data class I think.
I need to figure out what I am going to do about the glade problem (The druid widget is broken in newer versions then dropped in the newest version)
and the assistant widget that replaces it has problems too - or at least it did the last time I looked.
And I really need a different data model for Mesa pins....

I am preoccupied at the moment with Gscreen....

Chris,

The last piece of the puzzle fell into place this morning and I have a better understanding of the combobox treestore.

Thanks for the examples they helped a ton.

Your very welcome John!
samples to look at yet ???
