We then make the editor QLineEdit emit the returnPressed() signal, to which the application can connect to open the respective web page. Gramener pulled location-wise data from the Google Search/Suggest API. The doneCompletion() function, which is called by the event filter when either Enter or Return keys are pressed, stops the timer to prevent further requests and passes the text of the selected item to the editor. Finally, we adjust position and size of the popup to make sure that it pops up in the correct position below the editor, and show it.
