This Python package (mettler_toledo_quantos) creates a class named MettlerToledoDevice, to interface to Mettler Toledo Quantos using the Mettler Toledo Quantos Command Set as defined in the reference manual.

This package also creates a class named GUI_Class, which is a graphical user interface (GUI) used for generating an XML file containing information about how much of a reagent is to be dispensed into each sample vial.

Upon running GUI_Class.py, the main GUI window will be opened. There are 20 entry boxes which relate to the 20 sample vials to be dispensed.

1. Enter the desired masses in milligrams (mg) into each entry box
2. Click 'Send' button

The 'Send' button triggers the self.send_button_command(), which does a number of tasks:

1. All entry values are read as strings into variables self.e1-self.e20
2. A dictionary self.vals_dict is generated containing the vial number and the mass of reagent to be dispensed into each vial
3. self.create_xml() converts self.vals_dict into an xml file, titled 'new_values.xml'
4. The entry values are cleared using self.clear_values()
5. A popup window telling the user that the XML file has been created is shown

This button closes the GUI and terminates the program.

File > Clear Values

This removes any values in the entry boxes.

Help > About

This tells the user what the GUI is used for and gives information about the developers.
