Problem This is in response to Zach's post titled "GtkEntryCompletion to autofill multiple fields".
He has set up a GtkEntryCompletion similar to the following:
When the user has selected a state code, say "AZ", without pressing any other key or button, he would like some GtkEntry fields to be immediately populated with relevant data. In this example, I populate another GtkEntry field with the corresponding state name "Arizona" as shown below:
Solution
- We make use of the signal match-selected which is emitted when a string is selected from a GtkEntryCompletion.
