def populate(self):
        # This function will be used to populate the UI. Shocking. I know.

        # First lets clear all the items that are in the list to start fresh
        self.listWidget.clear()

        # Then we ask our library to find everything again in case things changed
        self.library.find()

        # Now we iterate through the dictionary
        # This is why I based our library on a dictionary, because it gives us all the nice tricks a dictionary has
        for name, info in self.library.items():
            # We create an item for the list widget and tell it to have our controller name as a label
            item = QtWidgets.QListWidgetItem(name)

            # We set its tooltip to be the info from the json
            # The pprint.pformat will format our dictionary nicely
            item.setToolTip(pprint.pformat(info))

            # Finally we check if there's a screenshot available
            screenshot = info.get('screenshot')
            # If there is, then we will load it
            if screenshot:
                # So first we make an icon with the path to our screenshot
                icon = QtGui.QIcon(screenshot)
                # then we set the icon onto our item
                item.setIcon(icon)

            # Finally we add our item to the list
            self.listWidget.addItem(item)

# This is a convenience function to display our UI
