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

Here's an updated snippet which originally shared by mr. Panofish. Those great functions are same, but now can be used on never versions of PyQt and Python with minor changes if needed. Thx mr. Panofish, long live OpenSource! :)

Changes:

• Updated for Python3 and PyQt5
• Added geometry save\restore
• Added QRadioButton save\restore

• SetCheckState() replcaed with SetChecked() in order to avoid tristate

  def guisave(self):
  
    # Save geometry
      self.settings.setValue('size', self.size())
      self.settings.setValue('pos', self.pos())
  
      for name, obj in inspect.getmembers(ui):
        # if type(obj) is QComboBox:  # this works similar to isinstance, but missed some field... not sure why?
        if isinstance(obj, QComboBox):
            name = obj.objectName()  # get combobox name
            index = obj.currentIndex()  # get current index from combobox
            text = obj.itemText(index)  # get the text for current index
            settings.setValue(name, text)  # save combobox selection to registry
  
        if isinstance(obj, QLineEdit):
            name = obj.objectName()
            value = obj.text()
            settings.setValue(name, value)  # save ui values, so they can be restored next time
  
        if isinstance(obj, QCheckBox):
            name = obj.objectName()
            state = obj.isChecked()
            settings.setValue(name, state)
  
        if isinstance(obj, QRadioButton):
            name = obj.objectName()
            value = obj.isChecked()  # get stored value from registry
            settings.setValue(name, value)
  
  
  def guirestore(self):
  
    # Restore geometry  
    self.resize(self.settings.value('size', QtCore.QSize(500, 500)))
    self.move(self.settings.value('pos', QtCore.QPoint(60, 60)))
  
    for name, obj in inspect.getmembers(ui):
        if isinstance(obj, QComboBox):
            index = obj.currentIndex()  # get current region from combobox
            # text   = obj.itemText(index)   # get the text for new selected index
            name = obj.objectName()
  
            value = (settings.value(name))
  
            if value == "":
                continue
  
            index = obj.findText(value)  # get the corresponding index for specified string in combobox
  
              if index == -1:  # add to list if not found
                  obj.insertItems(0, [value])
                  index = obj.findText(value)
                  obj.setCurrentIndex(index)
              else:
                  obj.setCurrentIndex(index)  # preselect a combobox value by index
  
        if isinstance(obj, QLineEdit):
            name = obj.objectName()
            value = (settings.value(name).decode('utf-8'))  # get stored value from registry
            obj.setText(value)  # restore lineEditFile
  
        if isinstance(obj, QCheckBox):
            name = obj.objectName()
            value = settings.value(name)  # get stored value from registry
            if value != None:
                obj.setChecked(strtobool(value))  # restore checkbox
  
        if isinstance(obj, QRadioButton):
           name = obj.objectName()
           value = settings.value(name)  # get stored value from registry
           if value != None:
               obj.setChecked(strtobool(value))
