To build flexible UIs, you'll need a mix of UI elements that inherit from [code]Control[/code] and [Container] nodes. [b]User Interface nodes and input[/b] Godot sends input events to the scene's root node first, by calling [method Node._input]. [method Node._input] forwards the event down the node tree to the nodes under the mouse cursor, or on keyboard focus. To do so, it calls [method MainLoop._input_event].
