Get variables from the GUI in program

Question

first, sorry for my english - im still learning. I´m a student from Germany and i learn Python.

I have a program which needs a lot of paramters for running so i build a gui by wxGlade. Now i want to get this paramters in my application. I saw some things. They used the GUI for editing a INI- File. And the application gets the paramters from these INI. But this is not what i want. I want to controll my application with the GUI. And it is very Important that i can save my Values in the GUI (so that the User should not do everything again).

Hope you understand what i mean. Here is my Code for the Gui (not ready but it is enough for doing the first steps)

Here is my GUI Code:

    #!/usr/bin/env python
    # -*- coding: UTF-8 -*-

Answer 1

There are ways to get the class objects and iterate over them.
But i'd suggest a restructure of the code and consider a container for your graphical elements instead, like this:

self.frames = {}

self.frames['_3_menubar'] = wx.MenuBar()
self.frames['frame_3_statusbarr'] = self.CreateStatusBar(1, 0)
self.frames['kartei'] = wx.Notebook(self, wx.ID_ANY, style=0)
self.frames['pane_all_settings'] = wx.Panel(self.kartei, wx.ID_ANY)
self.frames['label_5'] = wx.StaticText(self.pane_all_settings, wx.ID_ANY, _("Laufzeiteinstellungen"))
#... Etc etc, the rest of the objects

# And do something like this not only for your own sake
# But for getting rid huge amounts of code that can be compressed into stuff like this.
for item in ('Beenden', 'Datei', 'Bearbeiten', 'Dokumentationen', 'Hilfe'):
    self.frames['_3_menubar'].Append(wxglade_tmp_menu, _(item))

With this you can simply do:

def getAllValues(self):
    for frame in self.frames:
        value = self.getValue(self.frames[frame])
        yield (frame, value)

Or something similar, not sure what you want to do with the values but you could do:

def saveAllValues(self):
    with open('settings.ini', 'w') as fh:
        for frame, value in self.getAllValues():
            fh.write(frame + ':' + str(value) + '\n')

Answer 2

I would suggest you do the following:

• Use a dictionary to receive all the initial values. Let the names in the dictionary map to the names of your variables.
• Allow other modules to subscribe to this GUI using the Observer Pattern.
• When anything changes, or when the buttons are pressed, create a dictionary with the changes and notify all subscribers of the change.

This keeps the GUI cleanly separated from the rest of the program.
