public class QStringListModel
The QStringListModel class provides a model that supplies strings to views.
QStringListModel is an editable model that can be used for simple cases where you need to display a number of strings in a view widget, such as a QListView or a QComboBox.
The model provides all the standard functions of an editable model, representing the data in the string list as a model with one column and a number of rows equal to the number of items in the list.
Model indexes corresponding to items are obtained with the index() function, and item flags are obtained with flags. Item data is read with the data function and written with setData. The number of rows (and number of items in the string list) can be found with the rowCount function.
The model can be constructed with an existing string list, or strings can be set later with the setStringList convenience function. Strings can also be inserted in the usual way with the insertRows function, and removed with removeRows. The contents of the string list can be retrieved with the stringList convenience function.
An example usage of QStringListModel:
QStringListModel *model = new QStringListModel(); QStringList list; list << "a" << "b" << "c"; model->setStringList(list);

public QStringListModel()
Equivalent to QStringListModel(0).
public QStringListModel(QObject parent)
Constructs a string list model with the given parent.
public QStringListModel(java.util.List<java.lang.String> strings)
Equivalent to QStringListModel(strings, 0).
public QStringListModel(java.util.List<java.lang.String> strings, QObject parent)
Constructs a string list model containing the specified strings with the given parent.
Method Detail |
---|
public final void setStringList(java.util.List<java.lang.String> strings)
Sets the model's internal string list to strings. The model will notify any attached views that its underlying data has changed.
public final java.util.List<java.lang.String> stringList()
Returns the string list used by the model to store data.
public java.lang.Object data(QModelIndex index, int role)
Returns data for the specified role, from the item with the given index.
If the view requests an invalid index, an invalid variant is returned.
data
in class QAbstractItemModel
public Qt.ItemFlags flags(QModelIndex index)
Returns the flags for the item with the given index.
Valid items are enabled, selectable, and editable.
flags
in class QAbstractItemModel
public boolean insertRows(int row, int count, QModelIndex parent)
Inserts count rows into the model, beginning at the given row.
The parent index of the rows is optional and is only used for consistency with QAbstractItemModel. By default, a null index is specified, indicating that the rows are inserted in the top level of the model.
insertRows
in class QAbstractItemModel
public boolean removeRows(int row, int count, QModelIndex parent)
Removes count rows from the model, beginning at the given row.
The parent index of the rows is optional and is only used for consistency with QAbstractItemModel. By default, a null index is specified, indicating that the rows are removed in the top level of the model.
removeRows
in class QAbstractItemModel
public int rowCount(QModelIndex parent)
Returns the number of rows in the model. This value corresponds to the number of items in the model's internal string list.
The optional parent argument is in most models used to specify the parent of the rows to be counted. Because this is a list if a valid parent is specified, the result will always be 0.
rowCount
in class QAbstractItemModel
public boolean setData(QModelIndex index, java.lang.Object value, int role)
Sets the data for the specified role in the item with the given index in the model, to the provided value.
The dataChanged signal is emitted if the item is changed.
setData
in class QAbstractItemModel
public void sort(int column, Qt.SortOrder order)
This function is reimplemented for internal reasons.
sort
in class QAbstractItemModel
public static QStringListModel fromNativePointer(QNativePointer nativePointer)
nativePointer
- the QNativePointer of which object should be returned.
