Control
Inherits: CanvasItem < Node < Object
Inherited By: BaseButton, ColorRect, Container, GraphEdit, ItemList, Label, LineEdit, NinePatchRect, Panel, Popup, Range, ReferenceRect, RichTextLabel, Separator, Tabs, TextEdit, TextureRect, Tree, VideoPlayer
All user interface nodes inherit from Control. A control's anchors and margins adapt its position and size relative to its parent.
Description
Base class for all UI-related nodes. Control features a bounding rectangle that defines its extents, an anchor position relative to its parent control or the current viewport, 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 Control and Container nodes.
User Interface nodes and input
Godot sends input events to the scene's root node first, by calling Node._input. 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 MainLoop._input_event. Call accept_event so no other node receives the event. Once you accepted an input, it becomes handled so 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 grab_focus. Control nodes lose focus when another node grabs it, or if you hide the node in focus.
Sets mouse_filter to 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 add_*_override methods, like add_font_override. You can override the theme with the inspector.
Note: Theme items are not Object properties. This means you can't access their values using Object.get and Object.set. Instead, use get_color, get_constant, get_font, get_icon, get_stylebox, and the add_*_override methods provided by this class.

- SIZE_SHRINK_END = 8 --- Tells the parent Container to align the node with its end, either the bottom or the right edge. It doesn't work with the fill or expand size flags. Use with size_flags_horizontal and size_flags_vertical.
enum MouseFilter:
- MOUSE_FILTER_STOP = 0 --- The control will receive mouse button input events through _gui_input if clicked on. And the control will receive the mouse_entered and mouse_exited signals. These events are automatically marked as handled, and they will not propagate further to other controls. This also results in blocking signals in other controls.
- MOUSE_FILTER_PASS = 1 --- The control will receive mouse button input events through _gui_input if clicked on. And the control will receive the mouse_entered and mouse_exited signals. If this control does not handle the event, the parent control (if any) will be considered, and so on until there is no more parent control to potentially handle it. This also allows signals to fire in other controls. Even if no control handled it at all, the event will still be handled automatically, so unhandled input will not be fired.
- MOUSE_FILTER_IGNORE = 2 --- The control will not receive mouse button input events through _gui_input. The control will also not receive the mouse_entered nor mouse_exited signals. This will not block other controls from receiving these events or firing the signals. Ignored events will not be handled automatically.
enum GrowDirection:
- GROW_DIRECTION_BEGIN = 0 --- The control will grow to the left or top to make up if its minimum size is changed to be greater than its current size on the respective axis.
- GROW_DIRECTION_END = 1 --- The control will grow to the right or bottom to make up if its minimum size is changed to be greater than its current size on the respective axis.
- GROW_DIRECTION_BOTH = 2 --- The control will grow in both directions equally to make up if its minimum size is changed to be greater than its current size.
enum Anchor:
-
ANCHOR_BEGIN = 0 --- Snaps one of the 4 anchor's sides to the origin of the node's
Rect, in the top left. Use it with one of theanchor_*member variables, like anchor_left. To change all 4 anchors at once, use set_anchors_preset. -
ANCHOR_END = 1 --- Snaps one of the 4 anchor's sides to the end of the node's
Rect, in the bottom right. Use it with one of theanchor_*member variables, like anchor_left. To change all 4 anchors at once, use set_anchors_preset.

Controls whether the control will be able to receive mouse button input events through _gui_input and how these events should be handled. Also controls whether the control can receive the mouse_entered, and mouse_exited signals. See the constants to learn what each does.
bool rect_clip_content
| Default | false |
| Setter | set_clip_contents(value) |
| Getter | is_clipping_contents() |

Vector2 rect_scale
| Default | Vector2( 1, 1 ) |
| Setter | set_scale(value) |
| Getter | get_scale() |
The node's scale, relative to its rect_size. Change this property to scale the node around its rect_pivot_offset. The Control's hint_tooltip will also scale according to this value.
Note: This property is mainly intended to be used for animation purposes. Text inside the Control will look pixelated or blurry when the Control is scaled. To support multiple resolutions in your project, use an appropriate viewport stretch mode as described in the documentation instead of scaling Controls individually.
Note: If the Control node is a child of a Container node, the scale will be reset to Vector2(1, 1) when the scene is instanced. To set the Control's scale when it's instanced, wait for one frame using yield(get_tree(), "idle_frame") then set its rect_scale property.
Vector2 rect_size
| Default | Vector2( 0, 0 ) |
| Getter | get_size() |
The size of the node's bounding rectangle, in pixels. Container nodes update this property automatically.
int size_flags_horizontal
| Default | 1 |
| Setter | set_h_size_flags(value) |
| Getter | get_h_size_flags() |
Tells the parent Container nodes how they should resize and place the node on the X axis. Use one of the SizeFlags constants to change the flags. See the constants to learn what each does.
float size_flags_stretch_ratio
| Default | 1.0 |
| Setter | set_stretch_ratio(value) |
| Getter | get_stretch_ratio() |
If the node and at least one of its neighbours uses the SIZE_EXPAND size flag, the parent Container will let it take more or less space depending on this property. If this node has a stretch ratio of 2 and its neighbour a ratio of 1, this node will take two thirds of the available space.
int size_flags_vertical
| Default | 1 |
| Setter | set_v_size_flags(value) |
| Getter | get_v_size_flags() |
Tells the parent Container nodes how they should resize and place the node on the Y axis. Use one of the SizeFlags constants to change the flags. See the constants to learn what each does.
Theme theme
| Setter | set_theme(value) |
| Getter | get_theme() |
Changing this property replaces the current Theme resource this node and all its Control children use.
Method Descriptions
bool _clips_input ( ) virtual
Virtual method to be implemented by the user. Returns whether _gui_input should not be called for children controls outside this control's rectangle. Input will be clipped to the Rect of this Control. Similar to rect_clip_content, but doesn't affect visibility.
If not overridden, defaults to false.
Vector2 _get_minimum_size ( ) virtual
Virtual method to be implemented by the user. Returns the minimum size for this control. Alternative to rect_min_size for controlling minimum size via code. The actual minimum size will be the max value of these two (in each axis separately).
If not overridden, defaults to Vector2.ZERO.
void _gui_input ( InputEvent event ) virtual
Virtual method to be implemented by the user. Use this method to process and accept inputs on UI elements. See accept_event.
Example: clicking a control.
func _gui_input(event):
if event is InputEventMouseButton:
if event.button_index == BUTTON_LEFT and event.pressed:
print("I've been clicked D:")
The event won't trigger if:
* clicking outside the control (see has_point);
* control has mouse_filter set to MOUSE_FILTER_IGNORE;
* control is obstructed by another Control on top of it, which doesn't have mouse_filter set to MOUSE_FILTER_IGNORE;
* control's parent has mouse_filter set to MOUSE_FILTER_STOP or has accepted the event;
* it happens outside parent's rectangle and the parent has either rect_clip_content or _clips_input enabled.
Object _make_custom_tooltip ( String for_text ) virtual
Virtual method to be implemented by the user. Returns a Control node that should be used as a tooltip instead of the default one. Use for_text parameter to determine what text the tooltip should contain (likely the contents of hint_tooltip).
The returned node must be of type Control or Control-derieved. It can have child nodes of any type. It is freed when the tooltip disappears, so make sure you always provide a new instance, not e.g. a node from scene. When null or non-Control node is returned, the default tooltip will be used instead.
Note: The tooltip is shrunk to minimal size. If you want to ensure it's fully visible, you might want to set its rect_min_size to some non-zero value.
Example of usage with custom-constructed node:
func _make_custom_tooltip(for_text):
var label = Label.new()
label.text = for_text
return label
Example of usage with custom scene instance:
func _make_custom_tooltip(for_text):
var tooltip = preload("SomeTooltipScene.tscn").instance()
tooltip.get_node("Label").text = for_text
return tooltip
void accept_event ( )
Marks an input event as handled. Once you accept an input event, it stops propagating, even to nodes listening to Node._unhandled_input or Node._unhandled_key_input.
void add_color_override ( String name, Color color )
Overrides the Color with given name in the theme resource the control uses.
Note: Unlike other theme overrides, there is no way to undo a color override without manually assigning the previous color.
Example of overriding a label's color and resetting it later:
# Override the child node "MyLabel"'s font color to orange.
$MyLabel.add_color_override("font_color", Color(1, 0.5, 0))
# Reset the color by creating a new node to get the default value:
var default_label_color = Label.new().get_color("font_color")
$MyLabel.add_color_override("font_color", default_label_color)
void add_constant_override ( String name, int constant )
Overrides an integer constant with given name in the theme resource the control uses. If the constant is 0, the override is cleared and the constant from assigned Theme is used.
void add_font_override ( String name, Font font )
Overrides the font with given name in the theme resource the control uses. If font is null or invalid, the override is cleared and the font from assigned Theme is used.
void add_icon_override ( String name, Texture texture )
Overrides the icon with given name in the theme resource the control uses. If icon is null or invalid, the override is cleared and the icon from assigned Theme is used.
void add_shader_override ( String name, Shader shader )
Overrides the Shader with given name in the theme resource the control uses. If shader is null or invalid, the override is cleared and the shader from assigned Theme is used.
void add_stylebox_override ( String name, StyleBox stylebox )
Overrides the StyleBox with given name in the theme resource the control uses. If stylebox is empty or invalid, the override is cleared and the StyleBox from assigned Theme is used.
Example of modifying a property in a StyleBox by duplicating it:
# The snippet below assumes the child node MyButton has a StyleBoxFlat assigned.
# Resources are shared across instances, so we need to duplicate it
# to avoid modifying the appearance of all other buttons.
var new_stylebox_normal = $MyButton.get_stylebox("normal").duplicate()
new_stylebox_normal.border_width_top = 3
new_stylebox_normal.border_color = Color(0, 1, 0.5)
$MyButton.add_stylebox_override("normal", new_stylebox_normal)
# Remove the stylebox override:
$MyButton.add_stylebox_override("normal", null)
bool can_drop_data ( Vector2 position, Variant data ) virtual
Godot calls this method to test if data from a control's get_drag_data can be dropped at position. position is local to this control.
This method should only be used to test the data. Process the data in drop_data.
func can_drop_data(position, data):
# Check position if it is relevant to you
# Otherwise, just check data
return typeof(data) == TYPE_DICTIONARY and data.has("expected")
void drop_data ( Vector2 position, Variant data ) virtual
Godot calls this method to pass you the data from a control's get_drag_data result. Godot first calls can_drop_data to test if data is allowed to drop at position where position is local to this control.
func can_drop_data(position, data):
return typeof(data) == TYPE_DICTIONARY and data.has("color")
func drop_data(position, data):
color = data["color"]
void force_drag ( Variant data, Control preview )
Forces drag and bypasses get_drag_data and set_drag_preview by passing data and preview. Drag will start even if the mouse is neither over nor pressed on this control.
The methods can_drop_data and drop_data must be implemented on controls that want to receive drop data.
float get_anchor ( Margin margin ) const
Returns the anchor identified by margin constant from Margin enum. A getter method for anchor_bottom, anchor_left, anchor_right and anchor_top.
Vector2 get_begin ( ) const
Returns margin_left and margin_top. See also rect_position.

CursorShape get_cursor_shape ( Vector2 position=Vector2( 0, 0 ) ) const
Returns the mouse cursor shape the control displays on mouse hover. See CursorShape.
Variant get_drag_data ( Vector2 position ) virtual
Godot calls this method to get data that can be dragged and dropped onto controls that expect drop data. Returns null if there is no data to drag. Controls that want to receive drop data should implement can_drop_data and drop_data. position is local to this control. Drag may be forced with force_drag.
A preview that will follow the mouse that should represent the data can be set with set_drag_preview. A good time to set the preview is in this method.
func get_drag_data(position):
var mydata = make_data()
set_drag_preview(make_preview(mydata))
return mydata
Vector2 get_end ( ) const
Returns margin_right and margin_bottom.

Returns the tooltip, which will appear when the cursor is resting over this control. See hint_tooltip.
void grab_click_focus ( )
Creates an InputEventMouseButton that attempts to click the control. If the event is received, the control acquires focus.
func _process(delta):
grab_click_focus() #when clicking another Control node, this node will be clicked instead

Returns true if icon with given name has a valid override in this Control node.
bool has_point ( Vector2 point ) virtual
Virtual method to be implemented by the user. Returns whether the given point is inside this control.
If not overridden, default behavior is checking if the point is within control's Rect.
Note: If you want to check if a point is inside the control, you can use get_rect().has_point(point).
bool has_shader_override ( String name ) const
Returns true if Shader with given name has a valid override in this Control node.
bool has_stylebox ( String name, String type="" ) const
Returns true if StyleBox with given name and associated with Control of given type exists in assigned Theme.

void minimum_size_changed ( )
Invalidates the size cache in this node and in parent nodes up to toplevel. Intended to be used with get_minimum_size when the return value is changed. Setting rect_min_size directly calls this method automatically.
void release_focus ( )
Give up the focus. No other control will be able to receive keyboard input.
void set_anchor ( Margin margin, float anchor, bool keep_margin=false, bool push_opposite_anchor=true )
Sets the anchor identified by margin constant from Margin enum to value anchor. A setter method for anchor_bottom, anchor_left, anchor_right and anchor_top.
If keep_margin is true, margins aren't updated after this operation.
If push_opposite_anchor is true and the opposite anchor overlaps this anchor, the opposite one will have its value overridden. For example, when setting left anchor to 1 and the right anchor has value of 0.5, the right anchor will also get value of 1. If push_opposite_anchor was false, the left anchor would get value 0.5.
void set_anchor_and_margin ( Margin margin, float anchor, float offset, bool push_opposite_anchor=false )
Works the same as set_anchor, but instead of keep_margin argument and automatic update of margin, it allows to set the margin offset yourself (see set_margin).
void set_anchors_and_margins_preset ( LayoutPreset preset, LayoutPresetMode resize_mode=0, int margin=0 )
Sets both anchor preset and margin preset. See set_anchors_preset and set_margins_preset.
void set_anchors_preset ( LayoutPreset preset, bool keep_margins=false )
Sets the anchors to a preset from LayoutPreset enum. This is code equivalent of using the Layout menu in 2D editor.
If keep_margins is true, control's position will also be updated.
void set_begin ( Vector2 position )
Sets margin_left and margin_top at the same time. Equivalent of changing rect_position.
void set_drag_forwarding ( Control target )
Forwards the handling of this control's drag and drop to target control.
Forwarding can be implemented in the target control similar to the methods get_drag_data, can_drop_data, and drop_data but with two differences:
- The function name must be suffixed with _fw
- The function must take an extra argument that is the control doing the forwarding
# ThisControl.gd
extends Control
func _ready():
set_drag_forwarding(target_control)
# TargetControl.gd
extends Control
func can_drop_data_fw(position, data, from_control):
return true
func drop_data_fw(position, data, from_control):
my_handle_data(data)
func get_drag_data_fw(position, from_control):
set_drag_preview(my_preview)
return my_data()
void set_drag_preview ( Control control )
Shows the given control at the mouse pointer. A good time to call this method is in get_drag_data. The control must not be in the scene tree.
export (Color, RGBA) var color = Color(1, 0, 0, 1)
func get_drag_data(position):
# Use a control that is not in the tree
var cpb = ColorPickerButton.new()
cpb.color = color
cpb.rect_size = Vector2(50, 50)
set_drag_preview(cpb)
return color
void set_end ( Vector2 position )
Sets margin_right and margin_bottom at the same time.
void set_focus_neighbour ( Margin margin, NodePath neighbour )
Sets the anchor identified by margin constant from Margin enum to Control at neighbor node path. A setter method for focus_neighbour_bottom, focus_neighbour_left, focus_neighbour_right and focus_neighbour_top.
void set_global_position ( Vector2 position, bool keep_margins=false )
Sets the rect_global_position to given position.
If keep_margins is true, control's anchors will be updated instead of margins.
void set_margin ( Margin margin, float offset )
Sets the margin identified by margin constant from Margin enum to given offset. A setter method for margin_bottom, margin_left, margin_right and margin_top.
void set_margins_preset ( LayoutPreset preset, LayoutPresetMode resize_mode=0, int margin=0 )
Sets the margins to a preset from LayoutPreset enum. This is code equivalent of using the Layout menu in 2D editor.
Use parameter resize_mode with constants from LayoutPresetMode to better determine the resulting size of the Control. Constant size will be ignored if used with presets that change size, e.g. PRESET_LEFT_WIDE.
Use parameter margin to determine the gap between the Control and the edges.
void set_position ( Vector2 position, bool keep_margins=false )
Sets the rect_position to given position.
If keep_margins is true, control's anchors will be updated instead of margins.
void set_rotation ( float radians )
Sets the rotation (in radians).
void set_size ( Vector2 size, bool keep_margins=false )
Sets the size (see rect_size).
If keep_margins is true, control's anchors will be updated instead of margins.
void show_modal ( bool exclusive=false )
Displays a control as modal. Control must be a subwindow. Modal controls capture the input signals until closed or the area outside them is accessed. When a modal control loses focus, or the ESC key is pressed, they automatically hide. Modal controls are used extensively for popup dialogs and menus.
If exclusive is true, other controls will not receive input and clicking outside this control will not close it.
void warp_mouse ( Vector2 to_position )
Moves the mouse cursor to to_position, relative to rect_position of this Control.
