<class name="Control" inherits="CanvasItem" category="Core" version="3.0.7">
<brief_description>
All User Interface nodes inherit from Control. Features anchors and margins to adapt its position and size to its parent.
</brief_description>
<description>
Base class for all User Interface or [i]UI[/i] related nodes. [code]Control[/code] features a bounding rectangle that defines its extents, an anchor position relative to its parent and margins that represent an offset to the anchor. The margins update automatically when the node, any of its parents, or the screen size change.
For more information on Godot's UI system, anchors, margins, and containers, see the related tutorials in the manual. 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]. Call [method accept_event] so no other node receives the event. Once you accepted an input, it becomes handled so [method Node._unhandled_input] will not process it.
Only one [code]Control[/code] node can be in keyboard focus. Only the node in focus will receive keyboard events. To get the focus, call [method grab_focus]. [code]Control[/code] nodes lose focus when another node grabs it, or if you hide the node in focus.
Set [member mouse_filter] to MOUSE_FILTER_IGNORE to tell a [code]Control[/code] 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 [code]Control[/code] node, it affects all of its children. To override some of the theme's parameters, call one of the [code]add_*_override[/code] methods, like [method add_font_override]. You can override the theme with the inspector.

Godot calls this method to get data that can be dragged and dropped onto controls that expect drop data. Return null if there is no data to drag. Controls that want to receive drop data should implement [method can_drop_data] and [method drop_data]. [code]position[/code] is local to this control. Drag may be forced with [method force_drag].
A preview that will follow the mouse that should represent the data can be set with [method set_drag_preview]. A good time to set the preview is in this method.
