Class TreeRowReference

java.lang.Object
org.javagi.base.ProxyInstance
org.gnome.gtk.TreeRowReference
All Implemented Interfaces:
Proxy
@Generated("org.javagi.JavaGI") @Deprecated public class TreeRowReference extends ProxyInstance
Deprecated.
Use ListModel instead
A GtkTreeRowReference tracks model changes so that it always refers to the same row (a GtkTreePath refers to a position, not a fixed row). Create a new GtkTreeRowReference with gtk_tree_row_reference_new().

  • Constructor Details

    • TreeRowReference

      public TreeRowReference(MemorySegment address)
      Deprecated.
      Create a TreeRowReference proxy instance for the provided memory address.
      Parameters:
      address - the memory address of the native object

    • TreeRowReference

      @Deprecated public TreeRowReference(TreeModel model, TreePath path)
      Deprecated.

      Creates a row reference based on path.

      This reference will keep pointing to the node pointed to by path, so long as it exists. Any changes that occur on model are propagated, and the path is updated appropriately. If path isn’t a valid path in model, then null is returned.

      Parameters:
      model - a GtkTreeModel
      path - a valid GtkTreePath to monitor

  • Method Details

    • getType

      public static @Nullable Type getType()
      Deprecated.
      Get the GType of the TreeRowReference class.
      Returns:
      the GType

    • getMemoryLayout

      public static MemoryLayout getMemoryLayout()
      Deprecated.
      The memory layout of the native struct.
      Returns:
      the memory layout

    • proxy

      @Deprecated public static @Nullable TreeRowReference proxy(GObject proxy, TreeModel model, TreePath path)
      Deprecated.

      You do not need to use this function.

      Creates a row reference based on path.

      This reference will keep pointing to the node pointed to by path, so long as it exists. If path isn’t a valid path in model, then null is returned. However, unlike references created with gtk_tree_row_reference_new(), it does not listen to the model for changes. The creator of the row reference must do this explicitly using gtk_tree_row_reference_inserted(), gtk_tree_row_reference_deleted(), gtk_tree_row_reference_reordered().

      These functions must be called exactly once per proxy when the corresponding signal on the model is emitted. This single call updates all row references for that proxy. Since built-in GTK objects like GtkTreeView already use this mechanism internally, using them as the proxy object will produce unpredictable results. Further more, passing the same object as model and proxy doesn’t work for reasons of internal implementation.

      This type of row reference is primarily meant by structures that need to carefully monitor exactly when a row reference updates itself, and is not generally needed by most applications.

      Parameters:
      proxy - a proxy GObject
      model - a GtkTreeModel
      path - a valid GtkTreePath to monitor
      Returns:
      a newly allocated GtkTreeRowReference

    • deleted

      @Deprecated public static void deleted(GObject proxy, TreePath path)
      Deprecated.
      Lets a set of row reference created by gtk_tree_row_reference_new_proxy() know that the model emitted the ::row-deleted signal.
      Parameters:
      proxy - a GObject
      path - the path position that was deleted

    • inserted

      @Deprecated public static void inserted(GObject proxy, TreePath path)
      Deprecated.
      Lets a set of row reference created by gtk_tree_row_reference_new_proxy() know that the model emitted the ::row-inserted signal.
      Parameters:
      proxy - a GObject
      path - the row position that was inserted

    • reordered

      @Deprecated public static void reordered(GObject proxy, TreePath path, TreeIter iter, @Nullable int @Nullable [] newOrder)
      Deprecated.
      Lets a set of row reference created by gtk_tree_row_reference_new_proxy() know that the model emitted the ::rows-reordered signal.
      Parameters:
      proxy - a GObject
      path - the parent path of the reordered signal
      iter - the iter pointing to the parent of the reordered
      newOrder - the new order of rows

    • copy

      @Deprecated public TreeRowReference copy()
      Deprecated.
      Copies a GtkTreeRowReference.
      Returns:
      a copy of this TreeRowReference

    • free

      @Deprecated public void free()
      Deprecated.
      Free’s reference. this TreeRowReference may be null

    • getModel

      @Deprecated public TreeModel getModel()
      Deprecated.
      Returns the model that the row reference is monitoring.
      Returns:
      the model

    • getPath

      @Deprecated public @Nullable TreePath getPath()
      Deprecated.
      Returns a path that the row reference currently points to, or null if the path pointed to is no longer valid.
      Returns:
      a current path

    • valid

      @Deprecated public boolean valid()
      Deprecated.
      Returns true if the this TreeRowReference is non-null and refers to a current valid path.
      Returns:
      true if this TreeRowReference points to a valid path
