The OnDragHover method is a virtual method in the Editor.NodeEditor.GraphView class. It is designed to handle the event when a drag operation hovers over the graph view. This method can be overridden in a derived class to provide custom behavior when a drag event is detected hovering over the graph view.
To use the OnDragHover method, you should override it in a subclass of GraphView. This allows you to define specific actions that should occur when a drag event hovers over the graph view. The method takes a single parameter, ev, which is of type Editor.Widget/DragEvent. This parameter provides information about the drag event, such as the position of the cursor and the data being dragged.
public class CustomGraphView : Editor.NodeEditor.GraphView
{
public override void OnDragHover(Editor.Widget.DragEvent ev)
{
// Custom logic for handling drag hover event
// For example, highlight potential drop targets
if (ev != null)
{
// Implement custom hover logic here
}
}
}
