Member Function Documentation

[signal] void QComboBox::activated(const QString &text)

This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

This signal is sent when the user chooses an item in the combobox. The item's text is passed. Note that this signal is sent even when the choice is not changed. If you need to know when the choice actually changes, use signal currentIndexChanged().

Note: Signal activated is overloaded in this class. To connect to this signal by using the function pointer syntax, Qt provides a convenient helper for obtaining the function pointer as shown in this example:

connect(comboBox, QOverload<const QString &>::of(&QComboBox::activated),
    [=](const QString &text){ /* ... */ });

[signal] void QComboBox::highlighted(const QString &text)

This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

This signal is sent when an item in the combobox popup list is highlighted by the user. The item's text is passed.

Note: Signal highlighted is overloaded in this class. To connect to this signal by using the function pointer syntax, Qt provides a convenient helper for obtaining the function pointer as shown in this example:

connect(comboBox, QOverload<const QString &>::of(&QComboBox::highlighted),
    [=](const QString &text){ /* ... */ });

bool QComboBox::autoCompletion() const

This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

Use completer() instead.

Note: Getter function for property autoCompletion.

See also setAutoCompletion().

Qt::CaseSensitivity QComboBox::autoCompletionCaseSensitivity() const

This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

See also setAutoCompletionCaseSensitivity().

void QComboBox::setAutoCompletion(bool enable)

This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.

void QComboBox::setAutoCompletionCaseSensitivity(Qt::CaseSensitivity sensitivity)

This function is obsolete. It is provided to keep old source code working. We strongly advise against using it in new code.
