Member Enumeration Documentation

◆ Roles

enum QDeclarativeSupportedCategoriesModel::Roles

\qmltype CategoryModel \instantiates QDeclarativeSupportedCategoriesModel \inqmlmodule QtLocation

Since: QtLocation 5.5

The CategoryModel type provides a model of the categories supported by a \l Plugin.

The CategoryModel type provides a model of the categories that are available from the current \l Plugin. The model supports both a flat list of categories and a hierarchical tree representing category groupings. This can be controlled by the \l hierarchical property.

The model supports the following roles:

\table \header

Role
Type
Description \row
category
\l Category
Category object for the current item. \row
parentCategory
\l Category
Parent category object for the current item. If there is no parent, null is returned. \endtable

The following example displays a flat list of all available categories:

\codeline

To access the hierarchical category model it is necessary to use a \l DelegateModel to access the child items.

\qmlproperty Plugin CategoryModel::plugin

This property holds the provider \l Plugin used by this model.

\qmlproperty bool CategoryModel::hierarchical

This property holds whether the model provides a hierarchical tree of categories or a flat list. The default is true.

\qmlmethod string QtLocation::CategoryModel::data(ModelIndex index, int role)

This method retrieves the model's data per index and role.

\qmlmethod string QtLocation::CategoryModel::errorString() const

This read-only property holds the textual presentation of the latest category model error. If no error has occurred, an empty string is returned.

An empty string may also be returned if an error occurred which has no associated textual representation.

\qmlmethod void QtLocation::CategoryModel::update()

Updates the model.

Note: The CategoryModel auto updates automatically when needed. Calling this method explicitly is normally not necessary.

◆ dataChanged [2/2]

void QAbstractItemModel::dataChanged	(	const QModelIndex &	topLeft,

signal

This signal is emitted whenever the data in an existing item changes.

If the items are of the same parent, the affected ones are those between topLeft and bottomRight inclusive. If the items do not have the same parent, the behavior is undefined.

When reimplementing the setData() function, this signal must be emitted explicitly.

The optional roles argument can be used to specify which data roles have actually been modified. An empty vector in the roles argument means that all roles should be considered modified. The order of elements in the roles argument does not have any relevance.
