Creating a GUI with Dropdown Menus
Part 2 of creating a GUI to convert units.
We'll cover the following...
Now you have a converter handy for converting MPa to psi. What if you want to convert between other units of pressure? Instead of hard-coding MPa and psi, you want to be able to give the user an OptionMenu of all of the available pressures from the Pint library. You will create a list of all available pressure units, then make two OptionMenus to let the user pick which pressures to convert between. The GUI will now look like this:
| Column 1 | Column 2 | Column 3 | |
|---|---|---|---|
| Row 1 | Label saying “Converter” |
||
| Row 2 | Label saying “Convert” |
Entry field for inputting a str |
OptionMenu with all pressures |
| Row 3 | Label saying “into” |
