Perspective - Coordinate Container

Component Palette Icon:


The Coordinate Container makes a component's size and location relative to its parent's size and location. Components can be fixed size, or optionally grow/shrink proportionally when the view is stretched.

Coordinate Containers are ideal to use in cases where you need components to overlap each other, such as adding a component on top of another (z-axis) to act as an overlay. They're also useful in cases where you do not want components within to resize - for example, building a diagram where each element is a separate component.

Components placed in coordinate containers can be rotated. The Rotate property has been moved to the Position Properties section of the Perspective Property Editor. For more information, see Working with Perspective Components.

New in 8.1.2
The Coordinate Container component has two pre-configured variants:

  • Fixed - Child layouts will be in fixed coordinate space.
  • Percent - Child layout will be stretched to different size containers.


Most Properties have binding options. For more information on Bindings, see Types of Bindings in Perspective. This section only documents the Props Category of properties. The other Categories are described on the Perspective Component Properties page.

NameDescriptionProperty Type
modeWhether child layouts should always be in fixed coordinate space, or stretched relative to different container sizes: fixed or percent.
Fixed mode uses absolute units, which reduces the amount of resizing of components within the container when launched across different display sizes. Percent mode uses relative units, which means child components will be able to resize appropriately when launched on different sized displays.
value: string
aspectRatioOnly applied in percent mode. Optional dimensions, in x:y format to apply to maintain container aspect ratio for different sizes. Empty string (or non x:y input) will disable this mode.value: string
styleUse Style to customize the visual style of the component. The Style menu contains all the tools for modifying text, background, margins, and borders. You can also specify a style class.object

Child Component Position Properties

When a component is placed inside of a coordinate container, it will inherit the position properties listed below. The values for x, y, width, and height will differ based on the mode of the coordinate container.

  • fixed: Values represent absolute lengths. Example, an x value of 100px means the left edge of the component starts 100 pixels from the left edge of the container.
  • percent: Values are in relative lengths. Example, say a component has an x value of 0.25. In this scenario, the left edge of the container would be 0, the right edge would be 1. So 0.25 would be 25% distance from the left edge of the container.
NameDescriptionProperty Type
xSpecifies the horizontal positioning of the component in pixels.value: numeric
ySpecifies the vertical positioning of the component in pixels.value: numeric
widthSpecifies the width of the component in pixels.value: numeric
heightSpecifies the height of the component in pixels.value: numeric
rotateSetting that sets the anchor and angle of rotation for the component.
  • anchor: The point around which the rotation happens. Either as an {x:number, y:number} object where x and y represent percentages such that {x:0, y:0} represents the (0%, 0%) or top-left corner of the component, or as a valid CSS transform-origin string. Can be a string or object.
  • angle: How much to rotate the component. Valid values include numbers (as degrees), and valid CSS angle strings such as '45deg', '2rad', '0.5turn', etc. Can be numeric or string
  • object

    In this example, we have a Coordinate container with a Cylindrical Tank component and a Slider component. We've set the container property to percent so that the components will grow and shrink with the container size.
