Slots can have different, incompatible types. + GraphNode is a [Container] control that represents a single data unit in a [GraphEdit] graph. You can customize the number, type, and color of left- and right-side connection ports. </brief_description> <description> - A GraphNode is a container. Each GraphNode can have several input and output slots, sometimes referred to as ports, allowing connections between GraphNodes. To add a slot to GraphNode, add any [Control]-derived child node to it. - After adding at least one child to GraphNode new sections will be automatically created in the Inspector called 'Slot'. When 'Slot' is expanded you will see list with index number for each slot. You can click on each of them to expand further. - In the Inspector you can enable (show) or disable (hide) slots. By default, all slots are disabled so you may not see any slots on your GraphNode initially. You can assign a type to each slot. Only slots of the same type will be able to connect to each other. You can also assign colors to slots. A tuple of input and output slots is defined for each GUI element included in the GraphNode. Input connections are on the left and output connections are on the right side of GraphNode. Only enabled slots are counted as connections. + GraphNode allows to create nodes for a [GraphEdit] graph with customizable content based on its child [Control]s. GraphNode is a [Container] and is responsible for placing its children on screen. This works similar to [VBoxContainer]. Children, in turn, provide GraphNode with so-called slots, each of which can have a connection port on either side. This is similar to how [TabContainer] uses children to create the tabs. + Each GraphNode slot is defined by its index and can provide the node with up to two ports: one on the left, and one on the right. By convention the left port is also referred to as the input port and the right port is referred to as the output port. Each port can be enabled and configured individually, using different type and color. The type is an arbitrary value that you can define using your own considerations. The parent [GraphEdit] will receive this information on each connect and disconnect request. + Slots can be configured in the Inspector dock once you add at least one child [Control]. The properties are grouped by each slot's index in the "Slot" section. + [b]Note:[/b] While GraphNode is set up using slots and slot indices, connections are made between the ports which are enabled. Because of that [GraphEdit] uses port's index and not slot's index. You can use [method get_connection_input_slot] and [method get_connection_output_slot] to get the slot index from the port index. </description> <tutorials> </tutorials> @@ -19,16 +20,16 @@ </method> <method name="clear_slot"> <return type="void" /> -
