When typing <labelname>.TextAlignment = " the dropdownbox with the text alignment values (for gui labels) shows an obsolete value (eAlignCentre):
eAlignCenter
eAlignCentre
eAlignLeft
eAlignRight
The properties-box in the editor shows correctly the 3 values:
Center
Left
Right
This is extra value exists for backward compatibility with some old scripts.
EDIT: in latest versions this value is only declared if you have script compat mode set to 3.4.1 or lower.
Autocomplete is filled automatically from the script headers, so it displays everything.
ah, right.
