Move Unselected Nodes Demo

This demo shows how the GraphEditorInputMode.moveUnselectedItemsInputMode can be constrained, e.g., with keys or custom hit testing.

Things to Try

Move a node around by dragging the top without selecting the node first. Note that the cursor indicates that the node can be moved.
Try the different modes provided by the Move Unselected Nodes combo box.
Try setting the Edge Creation Mode to At Port Candidates and see how it works in conjunction with moving unselected nodes.
Disable Move Selected Nodes which is the out of the box MoveInputMode to move selected nodes. When disabled, only the current Move Unselected Nodes setting is considered, therefore selected nodes may not be draggable.
Note that both, the standard and the special move input mode, can be enabled at the same time.

The Move Unselected Nodes combo box provides different modes which determine whether a node can be moved.

Always: Nodes can always be moved by dragging them without selecting them first. This is the standard behavior of the special move input mode.
Shift Not Pressed: Nodes cannot be moved if the Shift key is held down while dragging. Instead, this gesture may start edge creation if the Edge Creation Mode is set to default.
Drag at Top: Nodes can only be moved when dragged at their top. Note how the cursor changes when you hover over different areas of the node.
If Move Enabled: Nodes can only be moved if the Move Enabled button is activated.
Never: Unselected nodes cannot be moved.

The Edge Creation Mode combo box provides different behaviors for the edge creation gesture.

Default: The default edge creation behavior. When this is set, users may not be able to create edges because the node may be moved instead.
At Port Candidates: This allows edge creation to start at distinct port candidates which also works in conjunction with moving unselected nodes.
