Pythoncard question

[DarkBlue]

I am trying to port a Delphi database application
to python on linux with a firebird database backend
and I am using pythoncard to recreate the gui.

I will have about 25 delphi forms to
be recreated and I would like to know
what is the best way to call them up
from within each other .
There is a main screen where I must
be able to call up any of the subscreens
and on any given subscreen there would
be buttons to call up 1-5 of the other subscreens
or go back to the mainscreen.

The database is connected on the mainscreen
and relevant connections/cursors shall be accessible
from any of the subscreens.

While I am able to connect to the database and create the
different screens I am stumped at how to efficiently
call them up and pass the cursors between them as needed.

Sorry for the long post.


Thanks for any hint

Re: Pythoncard question

Hi, I'm doing a sort of symbolic linking app in Windows for my own
enjoyment, and figured I would do it in python for the same reason +
learning the language.

The following functions could obviously do with some refactoring. One
obvious thing would be to make wordsetter and wordsforfolder more
generic, and just pass a few extra parameters. But that seems sort of
stupid.

Any suggestions on refactoring here? other improvements?


def getwordslist(wo rd):
thisword = wordpath + word + ".xml"
if exists(thisword ):
doc = xml.dom.minidom .parse(thisword )
loc = doc.childNodes[0]
for i in range(0, len(loc.childNo des)):
if (loc.childNodes[i].firstChild.dat a == thispath):
break
else:
wordsetter(this word,doc,loc)


else :
doc = xml.dom.minidom .Document()
loc = doc.createEleme ntNS("", "locations" )
doc.appendChild (loc)
wordsetter(this word,doc,loc)

return None

def getfolderwords( word):

if exists(normpath (folderwords)):
doc = xml.dom.minidom .parse(folderwo rds)
loc = doc.childNodes[0]
wordsforfolder( word,doc,loc)


else :

doc = xml.dom.minidom .Document()
loc = doc.createEleme ntNS("", "wordlist")
doc.appendChild (loc)
xml.dom.ext.Pre ttyPrint(doc, open(normpath(f olderwords), "w"))
wordsforfolder( word,doc,loc)

return None


def wordsetter(word ,doc,loc):
thisloc = doc.createEleme ntNS("", "location")
xexpr= "//location[.='" + thispath + "']"

xp = Evaluate(xexpr, doc.documentEle ment)
if len(xp) < 1:

loc.appendChild (thisloc)
text = doc.createTextN ode(thispath)
thisloc.appendC hild(text)
fi = open(word, "w")
fi.write(doc.to xml())


def wordsforfolder( word,doc,loc):
thisloc = doc.createEleme ntNS("", "word")
xexpr= "//word[.='" + word + "']"

xp = Evaluate(xexpr, doc.documentEle ment)
if len(xp) < 1:

loc.appendChild (thisloc)
text = doc.createTextN ode(word)
thisloc.appendC hild(text)
fi = open(folderword s, "w")
fi.write(doc.to xml())

oops, sorry about that. I copied the message over in gmail but forgot
to change the subject.
