Single Selection Demo

This demo shows how to configure GraphEditorInputMode for single selection mode. In this mode, only one graph item can be selected at a time.

Things to Try

Toggle Single Selection Mode: Use the checkbox to switch between single selection and regular selection modes.
Toggle Selection State: Select a single node and toggle its selection state by pressing Ctrl + Space. This works in both single selection and regular mode due to a custom command binding.
Move Node Focus: Move the node focus (indicated by a thin dashed line) by holding down Ctrl and pressing an arrow key. Toggle the selection state of the focused item by pressing Ctrl + Space.

Disabled Marquee Selection: Try to drag the mouse over a set of nodes to select them - this won't work in single selection mode.
Disabled Multi-Selection: Try to extend the selection by holding the Ctrl key while clicking another node - this won't work in single selection mode.
Disabled Select All: Try to select all nodes by pressing Ctrl + A - this won't work in single selection mode.
