<![CDATA[How to get the text of a complete in a combobox]]>Hi Can someone help me with my problem, I have a combobox that I fill with a QList and now I have generated a search engine with the help of the QCompleter, so far everything is fine, but I have edited it to make it visually more attractive, and it worked correctly until I have trouble selecting with the mouse one of the options that the QCompleter threw at me and the selection does not respect me, it only respects me if I give an Enter with the keyboard, but only for a moment, someone could help me solve my problem.

MainWindow::MainWindow(QWidget *parent) :
    QMainWindow(parent),
    ui(new Ui::MainWindow)
{
    ui->setupUi(this);
 qApp->setStyleSheet("QAbstractItemView#completerPopup {font: 15pt ;color: rgb(255, 255, 255);}");
}

    QCompleter *completer = new QCompleter(list, this);
    completer->setFilterMode(Qt::MatchContains);
    completer->setCaseSensitivity(Qt::CaseInsensitive);
    completer->popup()->setObjectName("completerPopup");
    ui->cobobox->setCompleter(completer);

I manage to make it work but I have to remove some lines of code that are the ones that help me edit the QCompleter as Pupop.

    QCompleter *completer = new QCompleter(list, this);
    completer->setFilterMode(Qt::MatchContains);
    completer->setCaseSensitivity(Qt::CaseInsensitive);
    ui->cobobox->setCompleter(completer);

The error it throws when I select is the following
Setting a QCompleter on non-editable QComboBox is not allowed.

It was you who wrote

That's all I know.

I was reviewing the documentation and enabling setEditable only allows me to write to the Combobox and I have already achieved this from the GUI, my problem is that it does not allow me to select from the popup with the mouse. But with keyboard yes.

I had just done it before you answered me, and it doesn't affect it in the same way.

ui->combobox->setEditable(true);
ui->combobox->setCompleter(completer);

or I am doing something wrong again?

Did you do the setEditable(true) per the link? That is what makes the QComboBox editable. setInsertPolicy() is irrelevant.

The default QComboBox is just a dropdown non-editable list. It does not accept text input, so a QCompleter makes no sense. You have to set it editable to get an edit widget and a completer.

ui->combobox->setInsertPolicy(QComboBox::InsertAtCurrent);

And with all its possible combinations:

QComboBox::InsertAtTop
QComboBox::InsertAtBottom
QComboBox::InsertAfterCurrent
QComboBox::InsertBeforeCurrent
QComboBox::InsertAlphabetically

But it did not give me any favorable results.
Or is it that I'm wrong about something?

Setting a QCompleter on non-editable QComboBox is not allowed.

https://doc.qt.io/qt-5/qcombobox.html#editable-prop

This property holds whether the combo box can be edited by the user

By default, this property is false. The effect of editing depends on the insert policy.
