// The QCompleter doesn't seem to update the completion prefix when you delete anything, only when things are added.
|
|
// To get it to update correctly when the user deletes something, I'm using the combination of things:
|
|
//
|
|
// 1) If we have a completion, that text will be auto filled into the quick filter because of the completion model.
|
|
// So, we will compare those two values, and if they match, we know we want to search using the completion prefix.
|
|
//
|
|
// 2) If they don't match, it means that user deleted something, and the Completer didn't update it's internal state, so we'll just
|
|
// use whatever is in the text box.
|
|
//
|
|
// 3) When the text field is set to empty, the current completion gets invalidated, but the prefix doesn't, so that gets special cased out.
|
|
//
|
|
// Extra fun: If you type in something, "Like" then delete a middle character, "Lie", and then put the k back in. It will auto complete the E
|
|
// visually but the completion prefix will be the entire word.
