Here is the caller graph for this function:

◆ roleValue()

QT_BEGIN_NAMESPACE QVariant QQmlDelegateChoice::roleValue ( ) const

Encapsulates a delegate and when to use it.

\qmltype DelegateChoice

! \instantiates QQmlDelegateChoice \inqmlmodule Qt.labs.qmlmodels

The DelegateChoice type wraps a delegate and defines the circumstances in which it should be chosen.

DelegateChoices can be nested inside a DelegateChooser.

See also: DelegateChooser

\qmlproperty variant Qt.labs.qmlmodels::DelegateChoice::roleValue This property holds the value used to match the role data for the role provided by \l DelegateChooser::role.

Definition at line 27 of file qqmldelegatecomponent.cpp.

◆ roleValueChanged

void QQmlDelegateChoice::roleValueChanged ( )

signal

Referenced by setRoleValue().

Here is the caller graph for this function:

◆ row()

int QQmlDelegateChoice::row ( ) const

\qmlproperty int Qt.labs.qmlmodels::DelegateChoice::row This property holds the value used to match the row value of model elements.

With models that have only the index property (and thus only one column), this property should be intended as an index, and set to the desired index value.

Note: Setting both row and index has undefined behavior. The two are equivalent and only one should be used.

See also: index

\qmlproperty int Qt.labs.qmlmodels::DelegateChoice::index This property holds the value used to match the index value of model elements. This is effectively an alias for \l row.

signal

Referenced by setRow().
