Python PyQt4 functions to save and restore UI widget values?

Question

Before I attempt to write my own Python PyQt4 module functions... I wanted to ask if anyone has such a function to share.

In many of my python programs where I hav

Answer 1

I'm a novice programmer so I'm not sure where I was going wrong and please excuse my lack of proper terminology/ technical understanding but my application has multiple QWidget classes for different app 'states' that load/ unload different UI's(and related functions) per state - all in and out of a single main 'QMainWindow'

this is using @beesleep class implementation but it looks like the code in question is the same for all the above examples

I was having issues with -

def _is_handled_type(cls, widget):
    return any(isinstance(widget, t) for t in cls._get_handled_types())


for name, obj in inspect.getmembers(self)
    # print(name) <------------------------------
    if not self._is_handled_type...

The methods of self "QMainWindow" are returned instead of all active child widgets.

.

My fix was this. I deleted - ***this part is not necessary, the code is just no longer used

@classmethod
def _is_handled_type(cls, widget):
    return any(isinstance(widget, t) fort in cls._get_handled_types())

Then changed in _gui_save() and _gui_restore() -

for name, obj in inspect.getmembers(self):
    if not self._is_handled_type(obj):
        continue
    if name in self._names_to_avoid: # _gui_restore()
        continue                     # _gui_restore()
        name = obj.objectName()
        value = None

To -

for child in self._get_handled_types():

    for obj in self.findChildren(child):

        if obj:

            name = obj.objectName()
            if name in self._names_to_avoid: # _gui_restore()
                continue                     # _gui_restore()
            value = None

The last step is that you have to assign a name to each object that you want to save

self.q_list = QListWidget()
self.q_list.setObjectName("List")
...
self.q_text = QLineEdit('enter text')
self.q_text.setObjectName("Text")

.

for child in self._get_handled_types():
    for obj in self.findChildren(child):
        if obj:
            name = obj.objectName()

            print(name, obj) <-------------

Returns

Text 
List 

final note... if you want to see where the settings file is being saved then add - print(self.settings.fileName()) under the init

cheers!
