Closure Application Override APIs#

To override any of the following AppTask hooks, declare the corresponding *Impl() method in CustomerAppTask.h and implement it in CustomerAppTask.cpp. Ensure that the method signature matches the declaration in autogen/AppTaskImpl.h.

AppTask#


Override	Public API	Default behavior
`AppInitImpl`	`AppInit`	Registers the button callback, initializes the display, and initializes Closure Manager.
`ButtonEventHandlerImpl`	`ButtonEventHandler`	Routes closure button presses to `ClosureButtonActionEventHandler` and function button events to the base application handler.
`ClosureButtonActionEventHandlerImpl`	`ClosureButtonActionEventHandler`	Stops motion if a closure action is in progress; otherwise, it starts a MoveTo toward the opposite position.
`DMPostAttributeChangeCallbackImpl`	`DMPostAttributeChangeCallback`	Logs Identify attribute changes.
`DMClosureControlClusterAttributeChangedCallbackImpl`	`DMClosureControlClusterAttributeChangedCallback`	Refreshes the UI when Closure Control `MainState` or `OverallCurrentState` changes.
`DMClosureDimensionClusterAttributeChangedCallbackImpl`	`DMClosureDimensionClusterAttributeChangedCallback`	Logs Closure Dimension attribute changes.

ClosureManager#

These APIs use the Closure app's separate manager override chain. Declare and implement the corresponding *Impl() methods in CustomerAppManager, which derives from ClosureManagerImpl<CustomerAppManager>. Use autogen/ClosureManagerImpl.h for exact signatures. Do not place these overrides in CustomerAppTask.


Override	Public API	Default behavior
`InitImpl`	`Init`	Initializes the closure timer, closure endpoints, and panel endpoints.
`OnCalibrateCommandImpl`	`OnCalibrateCommand`	Validates and starts an asynchronous closure calibration.
`OnMoveToCommandImpl`	`OnMoveToCommand`	Validates a MoveTo command and sets overall panel targets.
`OnStopCommandImpl`	`OnStopCommand`	Stops the active closure operation and completes the stop action.
`OnSetTargetCommandImpl`	`OnSetTargetCommand`	Validates a SetTarget command and sets the selected panel target.
`OnStepCommandImpl`	`OnStepCommand`	Validates a Step command and sets the selected panel step target.
`HandleClosureActionCompleteImpl`	`HandleClosureActionComplete`	Finalizes a completed calibrate, stop, move, or unlatch action.
`HandleClosureMotionActionImpl`	`HandleClosureMotionAction`	Advances closure panels toward their target positions.
`HandleClosureUnlatchActionImpl`	`HandleClosureUnlatchAction`	Updates closure and panel states for an unlatch action.
`GetPanelNextPositionImpl`	`GetPanelNextPosition`	Calculates the next position between a panel's current and target positions.
`HandlePanelSetTargetActionImpl`	`HandlePanelSetTargetAction`	Advances one panel toward a SetTarget position.
`HandlePanelUnlatchActionImpl`	`HandlePanelUnlatchAction`	Updates one panel for an unlatch action.
`HandlePanelStepActionImpl`	`HandlePanelStepAction`	Applies a Step action to one panel.
