The OnDragHover method is a virtual method in the Editor.SceneViewportWidget class. It is designed to handle drag hover events within the scene viewport widget. This method is called when a drag operation is hovering over the widget, allowing for custom behavior to be implemented during this interaction.
To use the OnDragHover method, you should override it in a subclass of Editor.SceneViewportWidget. This allows you to define specific actions that should occur when a drag event hovers over the widget. 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 and data being dragged.
public class CustomSceneViewportWidget : Editor.SceneViewportWidget
{
public override void OnDragHover(Editor.Widget.DragEvent ev)
{
// Custom logic for handling drag hover
// For example, highlight the widget or show a tooltip
HighlightWidget();
}
private void HighlightWidget()
{
// Implementation for highlighting the widget
}
}
