How could I make a good application architecture in Python with PyQt? -

i think appication doesn't have architecture. can't figure out how navigate between files correctly.

here non-standardized schema of application.

each file contains 1 class.

the principal problem can't variables class because of architecture of code. if put classes in 1 file, runs want separate classes (which qwindowand qwidget) in several files.

1. in every parent class, import each child :

from childfilename import childclassname 

for example, in optionwindow class, have :

from mainwindowfilename import mainwindowclassname toolbarfilename import toolbarsclassname menubarfilename import menubarclassname 

note 1 : better lisibility, name files same name classes. *for example : mytoolbar.py contains class mytoolbar(qtgui.qtoolbar)*

note 2 : need place empty __init__.py in every folder contains class)

note 3 : can place classes in different folders. if so, use :

from folder.childfilename import childclassname 

2. instantiate , call child functions or child variables :

in parent class :

self.child1=childclassname() self.child1.childfunction1() a1 = self.child1.childvariable1 

in child class :

... self.childvariable1 = 2 def childfunction1(self):     ... 

3. parent or grand-parents variables or functions in child : in parent class :

... self.parentvariable1 = 2 def parentfunction1(self):     ... 

in child class :

self.parent().parentfunction1()` a1 = self.parent().parentvariable1` 

note : self.parent().parent(). ... grand parent.

i hope helped
