Radio Button

This node places a radio button in the visual tree. The Radio Button must be placed in a Radio Button Group node to function properly.

You must specify a unique Value for each Radio Button node. Only one Radio Button in a Radio Button Group can be selected at once.

The core radio button has a very simple visual appearance and is most often used in other components as part of a design system. This control contains all logic such as accessibility etc. It can be styled in via it's properties, or you can use it only for the logic and create your own radio button component in your own design system.

Inputs

The main input of the Radio Button node is the Value input:

Data	Description
Value	The value for this radio button. The value of the selected radio button in a radio button group will be passed as the Value output of the radio button group. All radio buttons in a group should have unique values.
Background Color	The background color when the radio button is "checked".

It can be enabled and disabled using the Enabled input:

The Checkbox node has a set of label properties that can be set:

Data	Description
Enable Label	Sets whether the label is visible or not.
Text Style	Set an existing text style to this node, or create a new text style from the current properties.
Label	A text string that will be shown as the label on the button.
Spacing	The spacing between the label and the checkbox.

Similarly, it has a set of icon properties:

Data	Description
Enable Icon	Sets whether the icon is visible or not.
Type	Use this to set if you want to use a predefined `icon` or a custom `image` from the project folder.
Source	Where to get the icon.
Placement	Sets whether the icon should be to the `left` or to the `right` of the Label
Size	The width of the icon in `px`.
Color	Sets the color of the icon. Only visible if Type is set to `icon`.

Visual

This node supports the following Visual Input Properties:

Outputs

The main output of the Radio Button node is the Checked output.

Data	Description
Checked	A boolean output that is true when this radio button control is checked and false if not. This is useful when using this control as a base for your own component that will represent visually that it is checked.

It also features a set of signals:

| Signal | Description | | ------------------------------------------------ | ----------------------------------------------------------------------------------------------------------------------------- | | Changed | A signal is sent on this output when the value of the control is changed by user interaction. | | Focused | A signal is sent on this output when the control is focused. | | Blurred | A signal is sent on this output when the control is blurred, i.e. it has lost the input focus. | | Pointer Down | Emitted when the mouse is pressed or finger is down on the node. | | Pointer Up | Emitted when the mouse is released or finger is lifted on the node. | | Hover Start | Emitted when the mouse enters the node. | | Hover End | Emitted when the mouse leaves the node. |

States

Apart from triggering signals the Checkbox node also notifies of its state through data outputs:

| Data | Description | | ----------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Enabled | A boolean output that is true if the control is in Enabled state and false if it is Disabled. This is useful when using this control as a base for your own component that will represent visually that it is enabled or disabled. | | Focused | This is a boolean type output that will be true if the control is in Focused state, and false otherwise. This is useful when using this control as a base for your own component that will represent visually that it is focused. This can be due to the user selecting the control for input or by using the keyboard. | | Hover | A boolean type output that is true when the user hovers over this control with the mouse and false otherwise. This is useful when using this control as a base for your own component that will represent visually that it is hovered. | | Pressed | A boolean output that is true when the user is currently pressing the control. This is useful when using this control as a base for your own component that will represent visually that it is pressed. |

This node supports the following Visual Output Properties:

Visual Input Properties

All visual nodes feature a plethora of visual properties that can be accessed both in the Property Panel and through inputs. These are documented below. Plese refer to the individual node documentation pages to see which nodes feature what visual properties.

When making a connection to the layout property, the values are a little different than the ones in the dropdown. Here is a list of the values, that should be passed in:

| Display Name | Value | | ----------------------- | -------- | | Align Bottom | bottom | | Align Vertical Center | center | | Align Top | top | | Align Left | left | | Align Horizontal Center | center | | Align Right | right |

Dimensions

Controling the width and height of the node is done with the Dimension Gadget.

The first four controls the Size Mode of the node. It decides how the width and height of the node is specified. From left to right, the options are:

| Data | Description | | ---------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------- | | Explicit width and height | Set the width and height directly in pixels or percentage. Percentage is in relation to the parent, so 100% is the same size as the parent. | | Explicit height, Content Width | The node will calculate the width to fit all of its children. The height is explicitly set. | | Explicit width, Content Height | The node will calculate the height to fit all of its children. The width is explicitly set. | | Content Size | Both the width and the height is calculated to fit all of the node's children. |

The other properties are:

| Data | Description | | ---------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Width | Specify the width of this node in pixels, percentage of parent's width or the unit vw which is percentage of the browser window width. | | Height | Specify the height of this node in pixels, percentage of parent's height or the unit vw which is percentage of the browser window height. | | Fixed | Controls if an element will try to resize and share space with siblings without going outside of the bounds of the parent.

If Fixed is enabled, the element will be the exact specified size. If it is disabled, the element will resize to fill up empty space, or shrink to make space for siblings. |

You can use the Dimension Contstraints Gadget to set a min and/or a max size for the node.

Layout

The supported properties of the Layout Gadget can be very different depending on the node. All possible properties are listed below.

• Position

Controls the layout of this node is in its parent group.

| Option | Description | | ------------------------------------------- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | In Layout | This node is part of the parent group layout, it will be stacked with its siblings depending on the parent group layout settings. | | Absolute | This node will not be part of the parent group layout, instead you are free to use the Pos X and Pos Y to place this node explicitly. | | Sticky | Behaves like In Layout, except when the node is about the be scrolled outside the parent. It'll stick to an edge of the parent instead of scrolling away. The edge it sticks to can be controlled with the Alignment input. |

• Layout Direction

By default all children are stacked. This property specifies the stacking direction.

| Data | Description | | -------------------------------------------- | ---------------------------------- | | Vertical | Children are stacked vertically. | | Horizontal | Children are stacked horizontally. | | None | Children are not stacked. |

When making a connection to the layout property, the values are a little different than the ones in the dropdown. Here is a list of the values, that should be passed in:

| Display Name | Value | | ------------ | -------- | | Vertical | column | | Horizontal | row | | None | none |

• Multi Line Wrap

This property specifies what happens with children that are stacked outside of the border of the node.

If Clip is enabled they will not be visible. | | On | Children are wrapped to the next row or column (depending on layout direction). | | On Reverse | Same as On but opposite layout direction. |

• Gap

This property is used to add spacing between children in the group.

| Data | Description | | ------------------------------------------------ | --------------------------------------------------------------------------------------------------------- | | Vertical Gap | Vertical space between children. Shown if Layout is set to Vertical or Multi Line Wrap is On. | | Horizontal Gap | Horizontal space between children. Shown if Layout is set to Horizontal or Multi Line Wrap is On. |

• Clip content

This property controls if elements that are too big to fit inside the node will be clipped.

If disabled, a group will always expand to contain all of its children. So if the children are taller than the size of the group, the group will expand and be larger than its specified size.

Align and justify content

This Gadget controls how children are aligned and justified by default. Children can override these settings with their Alignment input.

The first set of options control cross-axis alignment, meaning vertical alignment for horizontal layouts, and horizontal alignment for vertical layouts. From left to right, the options are:

| Option | Description | | ---------------------------------------------------- | ------------------------------------------------- | | Align items start | Children are stacked at the start of the parent. | | Align items center | Children are stacked at the center of the parent. | | Align items end | Children are stacked at the end of the parent. |

You can select to set the corner radius all corners at once, or only style individual corners. The styling for the individual corners will override the all-corners option.

The corner radius is specified in px or % of the nodes width.

Box Shadow

You use the Box Shadow Gadget to set the shadow behind or inside of the node.

Placement

The Placement Gadget lets you offset, rotate and scale the node. It uses CSS Transforms under the hood, meaning that the nod will still take up the original size and position in the visual tree.

| Data | Description | | ---------------------------------------------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- | | Pos X | The X position of the node. Either relative to its parent top left corner or relative to its layout position depending on the Position property.
