Enum for different pick policies.

Enumerator

SINGLE

Only one object can be selected at any time. When the user picks a new object, the previous selection will be unselected. If the user picks on nothing, the current selection will be unselected.

Note that if a new selection matches one already present in the selection list, neither a deselect nor a select notification callback will be made about that selection path.

TOGGLE

Picking an object toggles its selection state.

SHIFT

Same as SINGLE, but when shift key is pressed the selection policy will be changed to TOGGLE.

DISABLE

Disables selection handling.

Default constructor.

Constructor.

The argument should be the approximate number of children which is expected to be inserted below this node. The number need not be exact, as it is only used as a hint for better memory resource allocation.

Destructor.

This static method returns the SoType object associated with objects of this class.

Returns the type identification of an object derived from a class inheriting SoBase. This is used for runtime type checking and 'downward' casting.

Reimplemented from SoSeparator.

Reimplemented in SoExtSelection.

This API member is considered internal to the library, as it is not likely to be of interest to the application programmer.

Returns the SoFieldData class which holds information about fields in this node.

Returns a pointer to the class-wide field data storage object for this instance. If no fields are present, returns NULL.

Reimplemented from SoSeparator.

Reimplemented in SoExtSelection.

Adds path to the list of selected objects.

Adds node to the list of selected objects. The scene graph below the selection node will be searched, and the path to node will be added if found.

Remove path from the list of selected objects.

Remove objects which from the list of selected objects.

Remove node from the list of selected objects. The scene graph below the selection node will be searched, and the path to node will be removed if found.

If path is not already selected, add path to the list of selected objects. Otherwise remove path from the list of selected objects.

If node is not already selected, add path to the list of selected objects. Otherwise remove node from the list of selected objects.

Return TRUE if path is in the list of selected objects.

Return TRUE if the path to node is in the list of selected objects.

Clears the selection list.

Returns the number of selected objects.

Returns the list of selected objects.

Returns the index'th selected objects.

Operator for accessing selected objects.

Adds a callback which will be called every time an object is selected.

See also

removeSelectionCallback()

Removes one of the selection callbacks.

See also

addSelectionCallback()

Adds a callback which will be called every time an object is deselected.

See also

removeDeselectionCallback()

Removes one of the deselection callbacks.

See also

addDeselctionCallback()

Adds a callback which will be invoked when the user starts an interactive change to the list of selected objects.

This callback is useful for storing the old selection list for undo/redo functionality.

See also

addFinishCallback()

Removes f from the list of start callbacks.

See also

addStartCallback()

Adds a callback which will be invoked when the user has finished an interactive change to the list of selected objects.

See also

addStartCallback()

Removes f from the list of finish callbacks.

See also

addFinishCallback()

Sets the pick filter callback. This callback will be called when a path is about to be added to or removed from the list of selected objects. The callback function should return a replacement path that should be used instead of the picked path. The returned path will be ref'ed, copied, and then unref'ed again by the SoSelection node.

If no callback is set (the default), the picked path will be used for selecting/deselecting.

Possible return values from the callback:

• NULL: simulate that nothing was picked. This will clear the selection for the SINGLE policy. The handle event action will be halted.
• A path: the path will be selected/deselected. The handle event action will be halted.  
• A path containing only the selection node: as NULL, but action will not be halted.  
• An empty path or a path not containing the selection node: the pick will be ignored.  

if callOnlyIfSelectable is TRUE, the callback will only be called if the selection node is in the picked path.

When pickmatchflag is TRUE (the default), the mouse button release pick must match the mouse button press pick before object is selected/deselected.

This flag should normally not be of interest to application programmers.

Returns TRUE if pick matching is enabled.

See also

setPickMatching()

Returns TRUE if pick matching is enabled.

Action method for SoHandleEventAction.

Inspects the event data from action, and processes it if it is something which this node should react to.

Nodes influencing relevant state variables for how event handling is done also override this method.

Reimplemented from SoSeparator.

Reimplemented in SoExtSelection.
