Remarks

Use ListModel or ListModel<T> when your data is naturally arranged as a simple sequence of items, such as a list of names, products, or messages. This base class fixes the hierarchical parts of Model so subclasses can focus on item count, item data, and list-specific change notifications.

In practical terms, a list model has exactly one column at the root level and no child items. Valid parent indexes are treated as having zero rows and zero columns. If your data is arranged as rows and columns, prefer TableModel instead.

Most applications should derive from ListModel<T> rather than directly from ListModel, because the generic form automatically maps item values or public item properties to named roles.

Methods

ColumnCount(ModelIndex)

Returns the number of columns for the specified parent index.

public override sealed int ColumnCount(ModelIndex parent)

Parameters

parent ModelIndex

Returns

int

HasChildren(ModelIndex)

Returns whether the specified parent item has any children.

public override sealed bool HasChildren(ModelIndex parent)

Parameters

parent ModelIndex

Returns

bool

Index(int, int, ModelIndex)

Creates an index that identifies the item at the specified row and column under a parent.

public override sealed ModelIndex Index(int row, int column, ModelIndex parent)

Parameters

row int

column int

parent ModelIndex

Returns

ModelIndex

Parent(ModelIndex)

Returns the parent index for the specified item.

public override sealed ModelIndex Parent(ModelIndex index)

Parameters

index ModelIndex

Returns

ModelIndex

Sibling(int, int, ModelIndex)

Returns another item with the same parent as the specified item.

public override sealed ModelIndex Sibling(int row, int column, ModelIndex index)

Parameters

row int

column int

index ModelIndex

Returns

ModelIndex
