This property holds the number of items in the combo box.

This property holds the index of the current item in the combo box.

See also activated(), currentText, and highlightedIndex.

This property holds the text of the current item in the combo box.

See also currentIndex, displayText, and textRole.

This property holds a delegate that presents an item in the combo box popup.

It is recommended to use ItemDelegate (or any other AbstractButton derivatives) as the delegate. This ensures that the interaction works as expected, and the popup will automatically close when appropriate. When other types are used as the delegate, the popup must be closed manually. For example, if MouseArea is used:

delegate: Rectangle {
    // ...
    MouseArea {
        // ...
        onClicked: comboBox.popup.close()
    }
}

This property holds the text that is displayed on the combo box button.

By default, the display text presents the current selection. That is, it follows the text of the current item. However, the default display text can be overridden with a custom value.

ComboBox {
    currentIndex: 1
    displayText: "Size: " + currentText
    model: ["S", "M", "L"]
}

See also currentText and textRole.

This property holds whether the combo box button is flat.

A flat combo box button does not draw a background unless it is interacted with. In comparison to normal combo boxes, flat combo boxes provide looks that make them stand out less from the rest of the UI. For instance, when placing a combo box into a tool bar, it may be desirable to make the combo box flat so it matches better with the flat looks of tool buttons.

The default value is false.

This QML property was introduced in QtQuick.Controls 2.1.

This property holds the index of the highlighted item in the combo box popup list.

When a highlighted item is activated, the popup is closed, currentIndex is set to highlightedIndex, and the value of this property is reset to -1, as there is no longer a highlighted item.

See also highlighted() and currentIndex.

This property holds the drop indicator item.

See also Customizing ComboBox.

This property holds the model providing data for the combo box.

ComboBox {
    textRole: "key"
    model: ListModel {
        ListElement { key: "First"; value: 123 }
        ListElement { key: "Second"; value: 456 }
        ListElement { key: "Third"; value: 789 }
    }
}

This property holds the popup.

The popup can be opened or closed manually, if necessary:

onSpecialEvent: comboBox.popup.close()

See also Customizing ComboBox.

This property holds whether the combo box button is pressed.

This property holds the model role used for populating the combo box.

When the model has multiple roles, textRole can be set to determine which role should be displayed.

See also model, currentText, displayText, and ComboBox Model Roles.

This signal is emitted when the item at index is activated by the user.

An item is activated when it is selected while the popup is open, causing the popup to close (and currentIndex to change), or while the popup is closed and the combo box is navigated via keyboard, causing the currentIndex to change. The currentIndex property is set to index.

See also currentIndex.

This signal is emitted when the item at index in the popup list is highlighted by the user.

The highlighted signal is only emitted when the popup is open and an item is highlighted, but not necessarily activated.

See also highlightedIndex.

Decrements the current index of the combo box, or the highlighted index if the popup list is visible.

See also currentIndex and highlightedIndex.

Returns the index of the specified text, or -1 if no match is found.

The way the search is performed is defined by the specified match flags. By default, combo box performs case sensitive exact matching (Qt.MatchExactly). All other match types are case-insensitive unless the Qt.MatchCaseSensitive flag is also specified.

See also textRole.

Increments the current index of the combo box, or the highlighted index if the popup list is visible.

See also currentIndex and highlightedIndex.

Returns the text for the specified index, or an empty string if the index is out of bounds.

See also textRole.
