Retrieves the node's context menu actions.

Populates the provided vector with pointers to actions that should appear in the node's context menu.

Parameters:

  • actionVector Reference to a vector that will be filled with action pointers.

function handleMoveEvent#

Handles a move event. 

virtual void SBGDataGraphNode::handleMoveEvent (
    SBNode * node,
    const SBPosition3 & position
)

Called when a move interaction is detected on the node.

Parameters:

  • node Pointer to the SBNode that generated the event.
  • position The new position of the node in world coordinates.

function handlePressEvent#

Handles a press event. 

virtual void SBGDataGraphNode::handlePressEvent (
    SBNode * node,
    const SBPosition3 & position
)

Called when a press interaction is detected on the node.

Parameters:

  • node Pointer to the SBNode that generated the event.
  • position The position of the press in world coordinates.

function handleReleaseEvent#

Handles a release event. 

virtual void SBGDataGraphNode::handleReleaseEvent (
    SBNode * node,
    const SBPosition3 & position
)

Called when a release interaction is detected on the node.

Parameters:

  • node Pointer to the SBNode that generated the event.
  • position The position of the release in world coordinates.

function isSelectionDependent#

Returns true when the node's context menu actions depend on the current selection. 

virtual bool SBGDataGraphNode::isSelectionDependent () const

Returns whether the node's context menu actions depend on the current selection.

Indicates if the node's context menu actions vary based on the selection state.

Returns:

true if the context menu actions are selection-dependent; otherwise false.

function keyPressEvent#

Handles key press event. 

virtual void SBGDataGraphNode::keyPressEvent (
    SBNode * node,
    QKeyEvent * event,
    const SBPosition3 & position
)

Handles a key press event.

Called when a key is pressed while the node has focus.

Parameters:

  • node Pointer to the SBNode that generated the event.
  • event Pointer to the QKeyEvent containing details of the key press.
  • position The position of the event in world coordinates.

function keyReleaseEvent#

Handles key release event. 

virtual void SBGDataGraphNode::keyReleaseEvent (
    SBNode * node,
    QKeyEvent * event,
    const SBPosition3 & position
)

Handles a key release event.

Called when a key is released while the node has focus.

Parameters:

  • node Pointer to the SBNode that generated the event.
  • event Pointer to the QKeyEvent containing details of the key release.
  • position The position of the event in world coordinates.

function leaveEvent#
