Conditional enabling of menu items
I've made an add-on that creates a menu item, but I only want it to be
enabled if there is a spreadsheet open. No, it's worse than that, I
only want it enabled if there is a cell selected. Basically I want to
mimic the behaviour of the Format-Cells menu option. How do I detect
this status and dynamically enable and disable my menu item as these
things change?
