class: SliceListModel

[15:7] extends: object

A list model that presents a slice of another model. This is useful when implementing paging by setting the size to the number of elements per page and updating the offset whenever a different page is opened. GtkSliceListModel passes through sections from the underlying model.

Methods

• SliceListModel (model = null, offset = null, size = null)

  Creates a new slice model. It presents the slice from @offset to offset +

  • @size of the given @model.
  • @p model is The model to use.
  • @p offset is the offset of the slice.
  • @p size is maximum size of the slice.

• toNativeHandle (Source)

  Normalizes a constructor argument into a raw pointer carrier. Accepts a raw NativeHandle, a raw NativeBuffer returned from fn.call(...), another generated wrapper exposing handle(), or null. Returns null when the argument carries no pointer.

  • @p Source is the raw handle, raw buffer, wrapper, or null.
  • @r A raw pointer carrier or null when no pointer is present.

• getLib ()

  Returns the opened native library for this generated wrapper.

  • @r The opened native library.

• handle ()

  Returns the wrapped NativeHandle.

  • @r The wrapped NativeHandle.

• isNull ()

  Returns true when the wrapped handle is null.

  • @r A bool.

• describe ()

  Returns a small string for debugging generated wrappers.

  • @r A string.

• asObject ()

  Wraps this handle as Object.

  • @r A Object object.

• asListModel ()

  Wraps this handle as ListModel.

  • @r A ListModel object.

• asSectionModel ()

  Wraps this handle as SectionModel.

  • @r A SectionModel object.

• getProperty (string Name)

  Reads one generated property by name.

• setProperty (string Name, Value)

  Writes one generated property by name.

• setModel (object Value)

  Child model to take slice from.

  • @p Value is the new property value.
  • @r None.

• setOffset (int Value)

  Offset of slice.

  • @p Value is the new property value.
  • @r None.

• setSize (int Value)

  Maximum size of slice.

  • @p Value is the new property value.
  • @r None.

• get_model ()

  Gets the model that is currently being used or %NULL if none.

• get_offset ()

  Gets the offset set via gtk_slice_list_model_set_offset().

• get_size ()

  Gets the size set via gtk_slice_list_model_set_size().

• set_model (object model)

  Sets the model to show a slice of. The model's item type must conform to

  • @self's item type.
  • @p model is The model to be sliced.
  • @r None.

• set_offset (int offset)

  Sets the offset into the original model for this slice. If the offset is too large for the sliced model, @self will end up empty.

  • @p offset is the new offset to use.
  • @r None.

• set_size (int size)

  Sets the maximum size. @self will never have more items than @size. It can however have fewer items if the offset is too large or the model sliced from doesn't have enough items.

  • @p size is the maximum size.
  • @r None.

• model ()

  Returns get_model as an Aussom list of wrapper objects. This companion method materializes the full collection up front; use get_model() when lazy or change-notify access is required.

  • @r An Aussom list of elements.

Methods

• properties ()

  Returns property metadata for SliceListModel.

  • @r A list.
