[Control] features a bounding rectangle that defines its extents, an anchor position relative to its parent control or the current viewport, and offsets relative to the anchor. The offsets update automatically when the node, any of its parents, or the screen size change. For more information on Godot's UI system, anchors, offsets, and containers, see the related tutorials in the manual. To build flexible UIs, you'll need a mix of UI elements that inherit from [Control] 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 [code]MainLoop._input_event[/code]. - [b]FIXME:[/b] No longer valid after DisplayServer split and Input refactoring. + Godot propagates input events via viewports. Each [Viewport] is responsible for propagating [InputEvent]s to their child nodes. As the [member SceneTree.root] is a [Window], this already happens automatically for all UI elements in your game. + Input events are propagated through the [SceneTree] from the root node to all child nodes by calling [method Node._input]. For UI elements specifically, it makes more sense to override the virtual method [method _gui_input], which filters out unrelated input events, such as by checking z-order, [member mouse_filter], focus, or if the event was inside of the control's bounding box. Call [method accept_event] so no other node receives the event. Once you accept an input, it becomes handled so [method Node._unhandled_input] will not process it. - Only one [Control] node can be in keyboard focus. Only the node in focus will receive keyboard events. To get the focus, call [method grab_focus]. [Control] nodes lose focus when another node grabs it, or if you hide the node in focus. + Only one [Control] node can be in focus. Only the node in focus will receive events. To get the focus, call [method grab_focus]. [Control] nodes lose focus when another node grabs it, or if you hide the node in focus. Sets [member mouse_filter] to [constant MOUSE_FILTER_IGNORE] to tell a [Control] node to ignore mouse or touch events. You'll need it if you place an icon on top of a button. [Theme] resources change the Control's appearance. If you change the [Theme] on a [Control] node, it affects all of its children. To override some of the theme's parameters, call one of the [code]add_theme_*_override[/code] methods, like [method add_theme_font_override]. You can override the theme with the inspector. [b]Note:[/b] Theme items are [i]not[/i] [Object] properties. This means you can't access their values using [method Object.get] and [method Object.set].
