Placeholder

In this example, we will demonstrate how to use the CreativeEditor SDK's CreativeEngine to manage placeholder behavior and controls through the block API.

Setup#

This example uses the headless CreativeEngine. See the Setup article for a detailed guide. To get started right away, you can also access the block API within a running CE.SDK instance via cesdk.engine.block. Check out the APIs Overview to see that illustrated in more detail.

Placeholder Behavior and Controls#

supportsPlaceholderBehavior(id: DesignBlockId): boolean

Checks whether the block supports placeholder behavior.

  • block: The block to query.
  • Returns True, if the block supports placeholder behavior.
setPlaceholderBehaviorEnabled(id: DesignBlockId, enabled: boolean): void

Enable or disable the placeholder behavior for a block.

  • id: The block whose placeholder behavior should be enabled or disabled.
  • enabled: Whether the placeholder behavior should be enabled or disabled.
isPlaceholderBehaviorEnabled(id: DesignBlockId): boolean

Query whether the placeholder behavior for a block is enabled.

  • id: The block whose placeholder behavior state should be queried.
  • Returns the enabled state of the placeholder behavior.
setPlaceholderEnabled(id: DesignBlockId, enabled: boolean): void

Enable or disable the placeholder function for a block.

  • id: The block whose placeholder function should be enabled or disabled.
  • enabled: Whether the function should be enabled or disabled.
isPlaceholderEnabled(id: DesignBlockId): boolean

Query whether the placeholder function for a block is enabled.

  • id: The block whose placeholder function state should be queried.
  • Returns the enabled state of the placeholder function.
supportsPlaceholderControls(id: DesignBlockId): boolean

Checks whether the block supports placeholder controls.

  • block: The block to query.
  • Returns True, if the block supports placeholder controls.
setPlaceholderControlsOverlayEnabled(id: DesignBlockId, enabled: boolean): void

Enable or disable the visibility of the placeholder overlay pattern for a block.

  • block: The block whose placeholder overlay should be enabled or disabled.
  • enabled: Whether the placeholder overlay should be shown or not.
  • Returns An empty result on success, an error otherwise.
isPlaceholderControlsOverlayEnabled(id: DesignBlockId): boolean

Query whether the placeholder overlay pattern for a block is shown.

  • block: The block whose placeholder overlay visibility state should be queried.
  • Returns An error if the block was invalid, otherwise the visibility state of the block's placeholder overlay pattern.
setPlaceholderControlsButtonEnabled(id: DesignBlockId, enabled: boolean): void

Enable or disable the visibility of the placeholder button for a block.

  • block: The block whose placeholder button should be shown or not.
  • enabled: Whether the placeholder button should be shown or not.
  • Returns An empty result on success, an error otherwise.
isPlaceholderControlsButtonEnabled(id: DesignBlockId): boolean

Query whether the placeholder button for a block is shown.

  • block: The block whose placeholder button visibility state should be queried.
  • Returns An error if the block was invalid, otherwise
