Problem This is in response to Zach's post titled "GtkEntryCompletion to autofill multiple fields".
If you have followed the solution in Part 1, there is one case you need to take care of. That is, even though you have set up GtkEntryCompletion, it's possible that the user decides to type the whole state code himself/herself and press Enter (e.g. AZ) without choosing anything from the auto-completion list. In this case we need to use the signal "activate" so that the state name will be populated as shown below:
Solution
- We make use of the signal activate which is emitted when the user types the whole state code (e.g. AZ) and press
<Enter>.
