General Concepts

These are the components which you can use for interface construction. If you have trouble finding the exact prop you need on a component, please note, that most of these components inherit from other basic components, such as Box. This component in particular provides a lot of styling options for all components, e.g. color and opacity, thus it is used a lot in this framework.

Event handlers. Event handlers are callbacks that you can attack to various element to listen for browser events. React supports camelcase (onClick) event names.

• Camel case names are what's called synthetic events, and are the preferred way of handling events in React, for efficiency and performance reasons. Please read React Event Handling to understand what this is about.

tgui/components

AnimatedNumber

This component provides animations for numeric values.

Props:

• value: number - Value to animate.
• initial: number - Initial value to use in animation when element first appears. If you set initial to 0 for example, number will always animate starting from 0, and if omitted, it will not play an initial animation.
• format: value => value - Output formatter.
  • Example: value => Math.round(value).
• children: (formattedValue, rawValue) => any - Pull the animated number to animate more complex things deeper in the DOM tree.
  • Example: (_, value) => <Icon rotation={value} />

BlockQuote

Just a block quote, just like this example in markdown:

Here's an example of a block quote.

Props:

• See inherited props: Box

Box

The Box component serves as a wrapper component for most of the CSS utility needs. It creates a new DOM element, a <div> by default that can be changed with the as property. Let's say you want to use a <span> instead:

<Box as="span" m={1}>
  <Button />
</Box>

This works great when the changes can be isolated to a new DOM element. For instance, you can change the margin this way.

However, sometimes you have to target the underlying DOM element. For instance, you want to change the text color of the button. The Button component defines its own color. CSS inheritance doesn't help.

To workaround this problem, the Box children accept a render props function. This way, Button can pull out the className generated by the Box.

<Box color="primary">{(props) => <Button {...props} />}</Box>

Box Units

Box units, like width, height and margins can be defined in two ways:

• By plain numbers
  • 1 unit equals 1rem for width, height and positioning properties.
  • 1 unit equals 0.5rem for margins and paddings.
• By strings with proper CSS units
  • For example: 100px, 2em, 1rem, 100%, etc.

If you need more precision, you can always use fractional numbers.

Default font size (1rem) is equal to 12px.

• lineHeight: number - Directly affects the height of text lines. Useful for adjusting button height.
• inline: boolean - Forces the Box to appear as an inline-block, or in other words, makes the Box flow with the text instead of taking all available horizontal space.
• m: number - Margin on all sides.
• mx: number - Horizontal margin.
• my: number - Vertical margin.
• mt: number - Top margin.
• mb: number - Bottom margin.
• ml: number - Left margin.
• mr: number - Right margin.

ByondUi

Displays a BYOND UI element on top of the browser, and leverages browser's layout engine to position it just like any other HTML element. It is especially useful if you want to display a secondary game map in your interface.

Example (button):

<ByondUi
  params={{
    id: 'test_button', // optional, can be auto-generated
    parent: 'some_container', // optional, defaults to the current window
    type: 'button',

    type: 'map',
  }} />

It supports a full set of Box properties for layout purposes.

Flex

Quickly manage the layout, alignment, and sizing of grid columns, navigation, components, and more with a full suite of responsive flexbox utilities.

If you are new to or unfamiliar with flexbox, we encourage you to read this CSS-Tricks flexbox guide.

Consists of two elements: <Flex> and <Flex.Item>. Both of them provide the most straight-forward mapping to flex CSS properties as possible.

One of the most basic usage of flex, is to align certain elements to the left, and certain elements to the right:

<Flex>
  <Flex.Item grow={1}>Button description</Flex.Item>
  <Flex.Item>
    <Button>Perform an action</Button>
  </Flex.Item>
</Flex>

Flex item with grow property will grow to take all available empty space, while flex items without grow will take the minimum amount of space. This effectively places the last flex item to the very end of the flex container.

Props:

• See inherited props: Box
• spacing: number - Removed in tgui 4.3, use Stack instead.
• inline: boolean - Makes flexbox container inline, with similar behavior to an inline property on a Box.
• direction: string - This establishes the main-axis, thus defining the direction flex items are placed in the flex container.
  • row (default) - left to right.
  • row-reverse - right to left.
  • column - top to bottom.
  • column-reverse - bottom to top.
• wrap: string - By default, flex items will all try to fit onto one line. You can change that and allow the items to wrap as needed with this property.
  • nowrap (default) - all flex items will be on one line
  • wrap - flex items will wrap onto multiple lines, from top to bottom.
  • wrap-reverse - flex items will wrap onto multiple lines from bottom to top.
• align: string - Default alignment of all children.
  • stretch (default) - stretch to fill the container.
  • start - items are placed at the start of the cross axis.
  • end - items are placed at the end of the cross axis.
  • center - items are centered on the cross axis.
  • baseline - items are aligned such as their baselines align.
• justify: string - This defines the alignment along the main axis. It helps distribute extra free space leftover when either all the flex items on a line are inflexible, or are flexible but have reached their maximum size. It also exerts some control over the alignment of items when they overflow the line.
  • flex-start (default) - items are packed toward the start of the flex-direction.
  • flex-end - items are packed toward the end of the flex-direction.
  • space-between - items are evenly distributed in the line; first item is on the start line, last item on the end line
  • space-around - items are evenly distributed in the line with equal space around them. Note that visually the spaces aren't equal, since all the items have equal space on both sides. The first item will have one unit of space against the container edge, but two units of space between the next item because that next item has its own spacing that applies.
  • space-evenly - items are distributed so that the spacing between any two items (and the space to the edges) is equal.
  • TBD (not all properties are supported in IE11).

Flex.Item

Props:

• See inherited props: Box
• order: number - By default, flex items are laid out in the source order. However, the order property controls the order in which they appear in the flex container.
• grow: number | boolean - This defines the ability for a flex item to grow if necessary. It accepts a unitless value that serves as a proportion. It dictates what amount of the available space inside the flex container the item should take up. This number is unit-less and is relative to other siblings.
• shrink: number | boolean - This defines the ability for a flex item to shrink if necessary. Inverse of grow.
• basis: number | string - This defines the default size of an element before any flex-related calculations are done. Has to be a length (e.g. 20%, 5rem), an auto or content keyword.
  • Important: IE11 flex is buggy, and auto width/height calculations can sometimes end up in a circular dependency. This usually happens, when working with tables inside flex (they have wacky internal widths and such). Setting basis to 0 breaks the loop and fixes all of the problems.
• align: string - This allows the default alignment (or the one specified by align-items) to be overridden for individual flex items. See: Flex.

Grid

Deprecated: This component is no longer recommended due to the variety of bugs that come with table-based layouts. We recommend using Flex instead.

Helps you to divide horizontal space into two or more equal sections. It is essentially a single-row Table, but with some extra features.

Example:

<Grid>
  <Grid.Column>
    <Section title="Section 1">Hello world!</Section>
  </Grid.Column>
  <Grid.Column size={2}>
    <Section title="Section 2">Hello world!</Section>
  </Grid.Column>
</Grid>

Props:

• See inherited props: Table

Grid.Column

Props:

• See inherited props: Table.Cell
• size: number (default: 1) - Size of the column relative to other columns.

Icon

Renders one of the FontAwesome icons of your choice.

<Icon name="plus" />

To smoothen the transition from v4 to v5, we have added a v4 semantic to transform names with -o suffixes to FA Regular icons. For example:

• square will get transformed to fas square
• square-o will get transformed to far square

Props:

• See inherited props: Box
• name: string - Icon name.
• size: number - Icon size. 1 is normal size, 2 is two times bigger. Fractional numbers are supported.
• rotation: number - Icon rotation, in degrees.
• spin: boolean - Whether an icon should be spinning. Good for load indicators.

Icon.Stack

Renders children icons on top of each other in order to make your own icon.

<Icon.Stack>
  <Icon name="pen" />
  <Icon name="slash" />
</Icon.Stack>

Props:

• See inherited props: Box
• children: Icon - Icons to stack.

Input

• alertAfter: number (optional) - When provided, will cause an alert symbol on the gauge to begin flashing in the color upon which the needle currently rests, as defined in ranges.
• alertBefore: number (optional) - As with alertAfter, but alerts below a value. If both are set, and alertAfter comes earlier, the alert will only flash when the needle is between both values. Otherwise, the alert will flash when on the active side of either threshold.
• format: function(value) => string (optional) - When provided, will be used to format the value of the metric for display.
• size: number (default: 1) - When provided scales the gauge.

Section

Section is a surface that displays content and actions on a single topic.

They should be easy to scan for relevant and actionable information. Elements, like text and images, should be placed in them in a way that clearly indicates hierarchy.

Section can also be titled to clearly define its purpose.

<Section title="Cargo">Here you can order supply crates.</Section>

If you want to have a button on the right side of an section title (for example, to perform some sort of action), there is a way to do that:

<Section title="Cargo" buttons={<Button>Send shuttle</Button>}>
  Here you can order supply crates.
</Section>

New: Sections can now be nested, and will automatically font size of the header according to their nesting level. Previously this was done via level prop, but now it is automatically calculated.

• step: number (default: 1) - Adjust value by this amount when dragging the input.
• stepPixelSize: number (default: 1) - Screen distance mouse needs to travel to adjust value by one step.
• format: value => value - Format value using this function before displaying it.
• suppressFlicker: number - A number in milliseconds, for which the input will hold off from updating while events propagate through the backend. Default is about 250ms, increase it if you still see flickering.
• onChange: (e, value) => void - An event, which fires when you release the input, or successfully enter a number.
• onDrag: (e, value) => void - An event, which fires about every 500ms when you drag the input up and down, on release and on manual editing.

Stack

A higher-level component, that is based on Flex. The main difference from Flex, is that this component automatically adds spacing between all stack items, reducing the boilerplate that you have to write!

Consists of two elements: <Stack> and <Stack.Item>.

Stacks can be vertical by adding a vertical property.

Example:

<Stack>
  <Stack.Item grow>Button description</Stack.Item>
  <Stack.Item>
    <Button>Perform an action</Button>
  </Stack.Item>
</Stack>

Example of a high-level window layout:

Stacks can be used for high level window layout. Make sure to use the fill property.

<Window>
  <Window.Content>
    <Stack fill>
      <Stack.Item>
        <Section fill>Sidebar</Section>
      </Stack.Item>
      <Stack.Item grow>
        <Stack fill vertical>
          <Stack.Item grow>
            <Section fill scrollable>
              Main content
            </Section>
          </Stack.Item>

          </Stack.Item>
        </Stack>
      </Stack.Item>
    </Stack>
  </Window.Content>
</Window>

Props:

• See inherited props: Flex
• fill: boolean - If set, stack will fill all available height.
• vertical: boolean - If set, stack will work in vertical mode.

Stack.Item

Props:

• See inherited props: Flex.Item

Table

A straight forward mapping to a standard html table, which is slightly simplified (does not need a <tbody> tag) and with sane default styles (e.g. table width is 100% by default).

Example:

<Table>
  <Table.Row>
    <Table.Cell bold>Hello world!</Table.Cell>
    <Table.Cell collapsing color="label">
      Label
    </Table.Cell>
  </Table.Row>
</Table>

Props:

• See inherited props: Box
• collapsing: boolean - Collapses table to the smallest possible size.

Table.Row

A straight forward mapping to <tr> element.

Props:

• See inherited props: Box

Table.Cell

A straight forward mapping to <td> element.

Props:

• See inherited props: Box
• collapsing: boolean - Collapses table cell to the smallest possible size, and stops any text inside from wrapping.

Tabs

Tabs make it easy to explore and switch between different views.

Here is an example of how you would construct a simple tabbed view:

<Tabs>
  <Tabs.Tab
    selected={tabIndex === 1}
    onClick={() => setTabIndex(1)}>
    Tab one
  </Tabs.Tab>
  <Tabs.Tab
    selected={tabIndex === 2}
    onClick={() => setTabIndex(2)}>
    Tab two
  </Tabs.Tab>
</Tabs>
<Box>
  Tab selected: {tabIndex}
</Box>

Notice that tabs do not contain state. It is your job to track the selected tab, handle clicks and place tab content where you need it. In return, you get a lot of flexibility in regards to how you can layout your tabs.

Tabs also support a vertical configuration. This is usually paired with Stack to render tab content to the right.

<Stack>
  <Stack.Item>
    <Tabs vertical>...</Tabs>
  </Stack.Item>
  <Stack.Item grow={1} basis={0}>
    Tab content.
  </Stack.Item>
</Stack>

If you need to combine a tab section with other elements, or if you want to add scrollable functionality to tabs, pair them with the Section component:

<Section fill fitted scrollable width="128px">
  <Tabs vertical>...</Tabs>
  ... other things ...
</Section>

Props:

• See inherited props: Box
• fluid: boolean - If true, tabs will take all available horizontal space.
• fill: boolean - Similarly to fill on Section, tabs will fill all available vertical space. Only makes sense in a vertical configuration.
• vertical: boolean - Use a vertical configuration, where tabs will be stacked vertically.
• children: Tab[] - This component only accepts tabs as its children.

Tabs.Tab

An individual tab element. Tabs function like buttons, so they inherit a lot of Button props.

Props:

• See inherited props: Button
• altSelection - Whether the tab buttons select via standard select (color change) or by adding a white indicator to the selected tab. Intended for usage on interfaces where tab color has relevance.
• icon: string - Tab icon.
• children: any - Tab text.
• onClick: function - Called when element is clicked.

Tooltip

A boxy tooltip from tgui 1. It is very hacky in its current state, and requires setting position: relative on the container.

Please note, that Button component has a tooltip prop, and it is recommended to use that prop instead.

Usage:

<Tooltip position="bottom" content="Box tooltip">
  <Box position="relative">Sample text.</Box>
</Tooltip>

Props:

• position?: string - Tooltip position. See Popper for valid options. Defaults to "auto".
• content: string - Content of the tooltip. Must be a plain string. Fragments or other elements are not supported.

tgui/layouts

Window

A root-level component, which draws the window chrome, titlebar, resize handlers, and controls the UI theme. All tgui interfaces must implement it in one way or another.

Example:

<Window theme="hackerman">
  <Window.Content scrollable>Hello, world!</Window.Content>
</Window>

Props:

• See inherited props: Box
• className: string - Applies a CSS class to the element.
• theme: string - A name of the theme.
  • For a list of themes, see packages/tgui/styles/themes.
• title: string - Window title.
• width: number - Window width.
• height: number - Window height.
• canClose: boolean - Controls the ability to close the window.
• children: any - Child elements, which are rendered directly inside the window. If you use a Dimmer or Modal in your UI, they should be put as direct childs of a Window, otherwise you should be putting your content into Window.Content.

Window.Content

Canonical window content, which is usually the main target of window focus. Can be scrollable.

Props:

• See inherited props: Box
• className: string - Applies a CSS class to the element.
• fitted: boolean - If true, removes all padding.
• scrollable: boolean - Shows or hides the scrollbar.
• children: any - Main content of your window.
