Autocomplete text field in qt?

Question

I'm new to QT, how to implement the autocomplete text box in qt or is there already a solution for this? I have a vector of words. Can someone give me advice on how to do this?

Answer 1

Take a look at QCompleter .

The QCompleter class provides shutdown based on the item model.

You can use QCompleter to provide automatic completion in any Qt widgets such as QLineEdit and QComboBox. When a user begins to enter a word, QCompleter offers possible ways to populate a word based on a list of words. A list of words is provided as a QAbstractItemModel. (For simple applications where the word list is static, you can pass a QStringList to the QCompleter constructor.)

Answer 2

You can use QComboBoxwith the attribute editableset totrue.
