Definition

This class is not supposed to be used by Plugins, but sometimes you may need access to peculiar signals or slots.

Public Slots
void	setExpanded (QModelIndex)
	Specifies a group as Expanded for the Geometric Objects view.

void	setCollapsed (QModelIndex)
	Specifies a group as Collapsed for the Geometric Objects view.

void	itemChanged ()
	Transmits a CGAL::Three::Scene_item::itemChanged() signal to the scene.

void	itemVisibilityChanged ()
	Transmits a CGAL::Three::Scene_item::itemVisibilityChanged() signal to the scene.

void	remove_item_from_groups (CGAL::Three::Scene_item *item)
	Removes `item` from all the groups of the scene.

void	redraw_model ()
	Re-organizes the sceneView.

void	setSelectedItemIndex (int i)
	Sets the selected item to the target index. More...

void	setSelectedItem (CGAL::Three::Scene_item *item_to_select)
	Does the same as setSelectedItem(int)

QList< int >	setSelectedItemsList (QList< int > l)
	Sets the target list of indices as the selected indices.

void	setItemVisible (int, bool b)
	Sets the item at index i to visible or not visible.

void	setItemA (int i)
	Sets the item_A as the item at index i .

void	setItemB (int i)
	Sets the item_B as the item at index i .

Signals
void	indexErased (Scene_interface::Item_id id)
	Is emitted when the ids of the items are changed.

void	itemPicked (const QModelIndex &modelindex)
	Emit this to mark `modelindex` as selected in the Geometric Objects view.

void	newItem (int)
	Is emitted when a new item is added to the scene.

void	updated_bbox (bool b)
	Emit this to re-compute the viewer's Bbox; If `b` is true, the scene will be recentered.

void	updated ()
	Emit this to redraw the scene.

void	itemAboutToBeDestroyed (CGAL::Three::Scene_item *item)
	Is emitted when `item` is erased.

void	selectionRay (double, double, double, double, double, double)
	Is emitted when the selection ray is changed.

void	selectionChanged (int i)
	Used to update the selected item in the Geometric Objects view.

void	itemIndexSelected (int i)
	Used when you don't want to update the selectedItem in the Geometric Objects view.

void	restoreCollapsedState ()
	Emit this to reset the collapsed state of all groups after the Geometric Objects view has been redrawn.

void	drawFinished ()
	Is emitted when draw() is finished.

Public Member Functions
void	updatePrimitiveIds (Viewer_interface , Scene_item item) Q_DECL_OVERRIDE
	Re-computes the primitiveIds for `item`

Public Member Functions inherited from CGAL::Three::Scene_interface
virtual void	itemChanged (Item_id i)=0
	Updates the information about the `i`th item in the Geometric Objects list and redraws the scene. More...

virtual void	itemChanged (CGAL::Three::Scene_item *item)=0
	Updates the information about `item` in the Geometric Objects list and redraws the scene. More...

virtual void	itemVisibilityChanged (CGAL::Three::Scene_item *)=0
	Re computes the scene Bbox without recentering it.

virtual void	setSelectedItem (Item_id)=0
	Clears the current selection then sets the selected item to the target index. More...

CGAL::Three::Scene_item *	selectedItem () const

Additional Inherited Members
Public Types inherited from CGAL::Three::Scene_interface
typedef CGAL::Bbox_3	Bbox
	A bounding box is a box with each face corresponding to an extremum of its contents.

typedef int	Item_id
	Integer used as the index of a Scene_item. More...

CGAL::Three::Scene_item* Scene::selectedItem ( ) const

void Scene::setSelectedItemIndex ( int i )

slot

Sets the selected item to the target index.

Emits a signal to notify that a new item is now selected, but does not update the Geometric Objects view. Used in intern and by the mainwindow
