Struct gdnative::api::Panel

pub struct Panel { /* fields omitted */ }

core class Panel inherits Control (unsafe).

Official documentation

See the documentation of this class in the Godot engine's official documentation.

Memory management

Non reference counted objects such as the ones of this type are usually owned by the engine.

Panel is a reference-only type. Persistent references can only exist in the unsafe Ref<Panel> form.

In the cases where Rust code owns an object of this type, for example if the object was just created on the Rust side and not passed to the engine yet, ownership should be either given to the engine or the object must be manually destroyed using Ref::free, or Ref::queue_free if it is a Node.

Class hierarchy

Panel inherits methods from:

• Control
• CanvasItem
• Node
• Object

Safety

All types in the Godot API have "interior mutability" in Rust parlance. To enforce that the official thread-safety guidelines are followed, the typestate pattern is used in the Ref and TRef smart pointers, and the Instance API. The typestate Access in these types tracks whether the access is unique, shared, or exclusive to the current thread. For more information, see the type-level documentation on Ref.

Implementations

impl Panel

pub fn new() -> Ref<Panel, Unique>

Creates a new instance of this object.

Because this type is not reference counted, the lifetime of the returned object is not automatically managed.

Immediately after creation, the object is owned by the caller, and can be passed to the engine (in which case the engine will be responsible for destroying the object) or destroyed manually using Ref::free, or preferably Ref::queue_free if it is a Node.

pub fn accept_event(&self)

Marks an input event as handled. Once you accept an input event, it stops propagating, even to nodes listening to [method Node._unhandled_input] or [method Node._unhandled_key_input].

pub fn add_color_override(&self, name: impl Into<GodotString>, color: Color)

Overrides the [Color] with given [code]name[/code] in the [member theme] resource the control uses.
				[b]Note:[/b] Unlike other theme overrides, there is no way to undo a color override without manually assigning the previous color.
				[b]Example of overriding a label's color and resetting it later:[/b]
				[codeblock]
				# 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)
				[/codeblock]

pub fn add_constant_override(&self, name: impl Into<GodotString>, constant: i64)

Overrides an integer constant with given [code]name[/code] in the [member theme] resource the control uses. If the [code]constant[/code] is [code]0[/code], the override is cleared and the constant from assigned [Theme] is used.

pub fn add_font_override(
    &self,
    name: impl Into<GodotString>,
    font: impl AsArg<Font>
)

Overrides the font with given [code]name[/code] in the [member theme] resource the control uses. If [code]font[/code] is [code]null[/code] or invalid, the override is cleared and the font from assigned [Theme] is used.

    &self,
    name: impl Into<GodotString>,
    texture: impl AsArg<Texture>
)

Overrides the icon with given [code]name[/code] in the [member theme] resource the control uses. If [code]icon[/code] is [code]null[/code] or invalid, the override is cleared and the icon from assigned [Theme] is used.

    &self,
    name: impl Into<GodotString>,
    shader: impl AsArg<Shader>
)

Overrides the [Shader] with given [code]name[/code] in the [member theme] resource the control uses. If [code]shader[/code] is [code]null[/code] or invalid, the override is cleared and the shader from assigned [Theme] is used.

pub fn add_stylebox_override(
    &self,
    name: impl Into<GodotString>,
    stylebox: impl AsArg<StyleBox>
)

Overrides the [StyleBox] with given [code]name[/code] in the [member theme] resource the control uses. If [code]stylebox[/code] is empty or invalid, the override is cleared and the [StyleBox] from assigned [Theme] is used.
				[b]Example of modifying a property in a StyleBox by duplicating it:[/b]
				[codeblock]
				# 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)
				[/codeblock]

pub fn force_drag(
    &self,
    data: impl OwnedToVariant,
    preview: impl AsArg<Control>
)

Forces drag and bypasses [method get_drag_data] and [method set_drag_preview] by passing [code]data[/code] and [code]preview[/code]. Drag will start even if the mouse is neither over nor pressed on this control.
				The methods [method can_drop_data] and [method drop_data] must be implemented on controls that want to receive drop data.

pub fn anchor(&self, margin: i64) -> f64

Anchors the top edge of the node to the origin, the center or the end of its parent control. It changes how the top margin updates when the node moves or changes size. You can use  one of the [enum Anchor] constants for convenience.

Default Arguments

• position - Vector2( 0, 0 )

pub fn custom_minimum_size(&self) -> Vector2D<f32, UnknownUnit>

The minimum size of the node's bounding rectangle. If you set it to a value greater than (0, 0), the node's bounding rectangle will always have at least this size, even if its content is smaller. If it's set to (0, 0), the node sizes automatically to fit its content, be it a texture or child nodes.

pub fn default_cursor_shape(&self) -> CursorShape

The default cursor shape for this control. Useful for Godot plugins and applications or games that use the system's mouse cursors.
			[b]Note:[/b] On Linux, shapes may vary depending on the cursor theme of the system.

pub fn get_end(&self) -> Vector2D<f32, UnknownUnit>

Returns [member margin_right] and [member margin_bottom].

pub fn focus_mode(&self) -> FocusMode

The focus access mode for the control (None, Click or All). Only one Control can be focused at the same time, and it will receive keyboard signals.

pub fn focus_neighbour(&self, margin: i64) -> NodePath

Tells Godot which node it should give keyboard focus to if the user presses the top arrow on the keyboard or top on a gamepad by default. You can change the key by editing the [code]ui_top[/code] input action. The node must be a [Control]. If this property is not set, Godot will give focus to the closest [Control] to the bottom of this one.

pub fn focus_next(&self) -> NodePath

Tells Godot which node it should give keyboard focus to if the user presses Tab on a keyboard by default. You can change the key by editing the [code]ui_focus_next[/code] input action.
			If this property is not set, Godot will select a "best guess" based on surrounding nodes in the scene tree.

pub fn get_focus_owner(&self) -> Option<Ref<Control, Shared>>

Returns the control that has the keyboard focus or [code]null[/code] if none.

pub fn focus_previous(&self) -> NodePath

Tells Godot which node it should give keyboard focus to if the user presses Shift+Tab on a keyboard by default. You can change the key by editing the [code]ui_focus_prev[/code] input action.
			If this property is not set, Godot will select a "best guess" based on surrounding nodes in the scene tree.

Returns the position and size of the control relative to the top-left corner of the screen. See [member rect_position] and [member rect_size].

pub fn h_grow_direction(&self) -> GrowDirection

Controls the direction on the horizontal axis in which the control should grow if its horizontal minimum size is changed to be greater than its current size, as the control always has to be at least the minimum size.

pub fn h_size_flags(&self) -> i64

Tells the parent [Container] nodes how they should resize and place the node on the X axis. Use one of the [enum SizeFlags] constants to change the flags. See the constants to learn what each does.

pub fn get_icon(
    &self,
    name: impl Into<GodotString>,
    _type: impl Into<GodotString>
) -> Option<Ref<Texture, Shared>>

Returns an icon from assigned [Theme] with given [code]name[/code] and associated with [Control] of given [code]type[/code].

Default Arguments

• type - ""

pub fn margin(&self, margin: i64) -> f64

Distance between the node's top edge and its parent control, based on [member anchor_top].
			Margins are often controlled by one or multiple parent [Container] nodes, so you should not modify them manually if your node is a direct child of a [Container]. Margins update automatically when you move or resize the node.

pub fn get_minimum_size(&self) -> Vector2D<f32, UnknownUnit>

Returns the minimum size for this control. See [member rect_min_size].

pub fn mouse_filter(&self) -> MouseFilter

Controls whether the control will be able to receive mouse button input events through [method _gui_input] and how these events should be handled. Also controls whether the control can receive the [signal mouse_entered], and [signal mouse_exited] signals. See the constants to learn what each does.

pub fn get_parent_area_size(&self) -> Vector2D<f32, UnknownUnit>

Returns the width/height occupied in the parent control.

pub fn get_parent_control(&self) -> Option<Ref<Control, Shared>>

Returns the parent control node.

pub fn pivot_offset(&self) -> Vector2D<f32, UnknownUnit>

By default, the node's pivot is its top-left corner. When you change its [member rect_scale], it will scale around this pivot. Set this property to [member rect_size] / 2 to center the pivot in the node's rectangle.

pub fn position(&self) -> Vector2D<f32, UnknownUnit>

The node's position, relative to its parent. It corresponds to the rectangle's top-left corner. The property is not affected by [member rect_pivot_offset].

pub fn get_rect(&self) -> Rect<f32, UnknownUnit>

Returns the position and size of the control relative to the top-left corner of the parent Control. See [member rect_position] and [member rect_size].

pub fn get_rotation(&self) -> f64

Returns the rotation (in radians).

pub fn scale(&self) -> Vector2D<f32, UnknownUnit>

The node's scale, relative to its [member rect_size]. Change this property to scale the node around its [member rect_pivot_offset]. The Control's [member hint_tooltip] will also scale according to this value.
			[b]Note:[/b] 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 [url=https://docs.godotengine.org/en/latest/tutorials/viewports/multiple_resolutions.html]documentation[/url] instead of scaling Controls individually.
			[b]Note:[/b] If the Control node is a child of a [Container] node, the scale will be reset to [code]Vector2(1, 1)[/code] when the scene is instanced. To set the Control's scale when it's instanced, wait for one frame using [code]yield(get_tree(), "idle_frame")[/code] then set its [member rect_scale] property.

pub fn size(&self) -> Vector2D<f32, UnknownUnit>

The size of the node's bounding rectangle, in pixels. [Container] nodes update this property automatically.

pub fn stretch_ratio(&self) -> f64

If the node and at least one of its neighbours uses the [constant 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.

    &self,
    name: impl Into<GodotString>,
    _type: impl Into<GodotString>
) -> Option<Ref<StyleBox, Shared>>

pub fn get_tooltip(
    &self,
    at_position: Vector2D<f32, UnknownUnit>
) -> GodotString

Returns the tooltip, which will appear when the cursor is resting over this control. See [member hint_tooltip].

Default Arguments

• at_position - Vector2( 0, 0 )

pub fn v_grow_direction(&self) -> GrowDirection

Controls the direction on the vertical axis in which the control should grow if its vertical minimum size is changed to be greater than its current size, as the control always has to be at least the minimum size.

pub fn v_size_flags(&self) -> i64

Tells the parent [Container] nodes how they should resize and place the node on the Y axis. Use one of the [enum SizeFlags] constants to change the flags. See the constants to learn what each does.

pub fn grab_click_focus(&self)

Creates an [InputEventMouseButton] that attempts to click the control. If the event is received, the control acquires focus.
				[codeblock]
				func _process(delta):
				    grab_click_focus() #when clicking another Control node, this node will be clicked instead
				[/codeblock]

pub fn grab_focus(&self)

Steal the focus from another control and become the focused control (see [member focus_mode]).

pub fn is_clipping_contents(&self) -> bool

Enables whether rendering of [CanvasItem] based children should be clipped to this control's rectangle. If [code]true[/code], parts of a child which would be visibly outside of this control's rectangle will not be rendered.

pub fn minimum_size_changed(&self)

Invalidates the size cache in this node and in parent nodes up to toplevel. Intended to be used with [method get_minimum_size] when the return value is changed. Setting [member rect_min_size] directly calls this method automatically.

• push_opposite_anchor - true

pub fn set_anchor_and_margin(
    &self,
    margin: i64,
    anchor: f64,
    offset: f64,
    push_opposite_anchor: bool
)

Works the same as [method set_anchor], but instead of [code]keep_margin[/code] argument and automatic update of margin, it allows to set the margin offset yourself (see [method set_margin]).

Default Arguments

• push_opposite_anchor - false

pub fn set_anchors_and_margins_preset(
    &self,
    preset: i64,
    resize_mode: i64,
    margin: i64
)

Sets both anchor preset and margin preset. See [method set_anchors_preset] and [method set_margins_preset].

Default Arguments

• resize_mode - 0
• margin - 0

pub fn set_anchors_preset(&self, preset: i64, keep_margins: bool)

Sets the anchors to a [code]preset[/code] from [enum Control.LayoutPreset] enum. This is code equivalent of using the Layout menu in 2D editor.
				If [code]keep_margins[/code] is [code]true[/code], control's position will also be updated.

Default Arguments

• keep_margins - false

pub fn set_begin(&self, position: Vector2D<f32, UnknownUnit>)

Sets [member margin_left] and [member margin_top] at the same time. Equivalent of changing [member rect_position].

pub fn set_clip_contents(&self, enable: bool)

pub fn set_custom_minimum_size(&self, size: Vector2D<f32, UnknownUnit>)

The minimum size of the node's bounding rectangle. If you set it to a value greater than (0, 0), the node's bounding rectangle will always have at least this size, even if its content is smaller. If it's set to (0, 0), the node sizes automatically to fit its content, be it a texture or child nodes.

pub fn set_default_cursor_shape(&self, shape: i64)

The default cursor shape for this control. Useful for Godot plugins and applications or games that use the system's mouse cursors.
			[b]Note:[/b] On Linux, shapes may vary depending on the cursor theme of the system.

pub fn set_drag_forwarding(&self, target: impl AsArg<Control>)

Forwards the handling of this control's drag and drop to [code]target[/code] control.
				Forwarding can be implemented in the target control similar to the methods [method get_drag_data], [method can_drop_data], and [method drop_data] but with two differences:
				1. The function name must be suffixed with [b]_fw[/b]
				2. The function must take an extra argument that is the control doing the forwarding
				[codeblock]
				# 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()
				[/codeblock]

pub fn set_drag_preview(&self, control: impl AsArg<Control>)

Shows the given control at the mouse pointer. A good time to call this method is in [method get_drag_data]. The control must not be in the scene tree.
				[codeblock]
				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

Sets [member margin_right] and [member margin_bottom] at the same time.

pub fn set_focus_mode(&self, mode: i64)

The focus access mode for the control (None, Click or All). Only one Control can be focused at the same time, and it will receive keyboard signals.

pub fn set_focus_neighbour(&self, margin: i64, neighbour: impl Into<NodePath>)

Tells Godot which node it should give keyboard focus to if the user presses the top arrow on the keyboard or top on a gamepad by default. You can change the key by editing the [code]ui_top[/code] input action. The node must be a [Control]. If this property is not set, Godot will give focus to the closest [Control] to the bottom of this one.

pub fn set_focus_next(&self, next: impl Into<NodePath>)

Tells Godot which node it should give keyboard focus to if the user presses Tab on a keyboard by default. You can change the key by editing the [code]ui_focus_next[/code] input action.
			If this property is not set, Godot will select a "best guess" based on surrounding nodes in the scene tree.

pub fn set_focus_previous(&self, previous: impl Into<NodePath>)

Tells Godot which node it should give keyboard focus to if the user presses Shift+Tab on a keyboard by default. You can change the key by editing the [code]ui_focus_prev[/code] input action.
			If this property is not set, Godot will select a "best guess" based on surrounding nodes in the scene tree.

pub fn set_global_position(
    &self,
    position: Vector2D<f32, UnknownUnit>,
    keep_margins: bool
)

Sets the [member rect_global_position] to given [code]position[/code].
				If [code]keep_margins[/code] is [code]true[/code], control's anchors will be updated instead of margins.

Default Arguments

• keep_margins - false

pub fn set_h_grow_direction(&self, direction: i64)

Controls the direction on the horizontal axis in which the control should grow if its horizontal minimum size is changed to be greater than its current size, as the control always has to be at least the minimum size.

pub fn set_h_size_flags(&self, flags: i64)

Tells the parent [Container] nodes how they should resize and place the node on the X axis. Use one of the [enum SizeFlags] constants to change the flags. See the constants to learn what each does.

pub fn set_margin(&self, margin: i64, offset: f64)

Distance between the node's top edge and its parent control, based on [member anchor_top].
			Margins are often controlled by one or multiple parent [Container] nodes, so you should not modify them manually if your node is a direct child of a [Container]. Margins update automatically when you move or resize the node.

pub fn set_margins_preset(&self, preset: i64, resize_mode: i64, margin: i64)

Sets the margins to a [code]preset[/code] from [enum Control.LayoutPreset] enum. This is code equivalent of using the Layout menu in 2D editor.
				Use parameter [code]resize_mode[/code] with constants from [enum Control.LayoutPresetMode] to better determine the resulting size of the [Control]. Constant size will be ignored if used with presets that change size, e.g. [code]PRESET_LEFT_WIDE[/code].
				Use parameter [code]margin[/code] to determine the gap between the [Control] and the edges.

Default Arguments

• resize_mode - 0
• margin - 0

pub fn set_mouse_filter(&self, filter: i64)

Controls whether the control will be able to receive mouse button input events through [method _gui_input] and how these events should be handled. Also controls whether the control can receive the [signal mouse_entered], and [signal mouse_exited] signals. See the constants to learn what each does.

pub fn set_pivot_offset(&self, pivot_offset: Vector2D<f32, UnknownUnit>)

By default, the node's pivot is its top-left corner. When you change its [member rect_scale], it will scale around this pivot. Set this property to [member rect_size] / 2 to center the pivot in the node's rectangle.

pub fn set_position(
    &self,
    position: Vector2D<f32, UnknownUnit>,
    keep_margins: bool
)

Sets the [member rect_position] to given [code]position[/code].
				If [code]keep_margins[/code] is [code]true[/code], control's anchors will be updated instead of margins.

Default Arguments

• keep_margins - false

pub fn set_rotation(&self, radians: f64)

Sets the rotation (in radians).

pub fn set_rotation_degrees(&self, degrees: f64)

The node's rotation around its pivot, in degrees. See [member rect_pivot_offset] to change the pivot's position.

pub fn set_scale(&self, scale: Vector2D<f32, UnknownUnit>)

The node's scale, relative to its [member rect_size]. Change this property to scale the node around its [member rect_pivot_offset]. The Control's [member hint_tooltip] will also scale according to this value.
			[b]Note:[/b] 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 [url=https://docs.godotengine.org/en/latest/tutorials/viewports/multiple_resolutions.html]documentation[/url] instead of scaling Controls individually.
			[b]Note:[/b] If the Control node is a child of a [Container] node, the scale will be reset to [code]Vector2(1, 1)[/code] when the scene is instanced. To set the Control's scale when it's instanced, wait for one frame using [code]yield(get_tree(), "idle_frame")[/code] then set its [member rect_scale] property.

pub fn set_size(&self, size: Vector2D<f32, UnknownUnit>, keep_margins: bool)

Sets the size (see [member rect_size]).
				If [code]keep_margins[/code] is [code]true[/code], control's anchors will be updated instead of margins.

Default Arguments

• keep_margins - false

pub fn set_stretch_ratio(&self, ratio: f64)

If the node and at least one of its neighbours uses the [constant 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.

pub fn set_theme(&self, theme: impl AsArg<Theme>)

Changing this property replaces the current [Theme] resource this node and all its [Control] children use.

pub fn set_tooltip(&self, tooltip: impl Into<GodotString>)

Changes the tooltip text. The tooltip appears when the user's mouse cursor stays idle over this control for a few moments, provided that the [member mouse_filter] property is not [constant MOUSE_FILTER_IGNORE]. You can change the time required for the tooltip to appear with [code]gui/timers/tooltip_delay_sec[/code] option in Project Settings.

pub fn set_v_grow_direction(&self, direction: i64)

Controls the direction on the vertical axis in which the control should grow if its vertical minimum size is changed to be greater than its current size, as the control always has to be at least the minimum size.

pub fn set_v_size_flags(&self, flags: i64)

Tells the parent [Container] nodes how they should resize and place the node on the Y axis. Use one of the [enum SizeFlags] constants to change the flags. See the constants to learn what each does.

pub fn show_modal(&self, exclusive: bool)

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 [code]exclusive[/code] is [code]true[/code], other controls will not receive input and clicking outside this control will not close it.

Default Arguments

• exclusive - false

pub fn warp_mouse(&self, to_position: Vector2D<f32, UnknownUnit>)

Moves the mouse cursor to [code]to_position[/code], relative to [member rect_position] of this [Control].
