Called when an action mode has been finished. The appropriate mode callback method will have already been invoked. Note that if you override this method you should always call through to the superclass implementation by calling super.onActionModeFinished(mode). If you override this method you*must*call through to the superclass implementation.
| | [Unit](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html) | [onActionModeStarted](https://developer.android.com/reference/kotlin/android/app/Dialog#onActionModeStarted(android.view.ActionMode))`(`mode:` `[ActionMode](https://developer.android.com/reference/kotlin/android/view/ActionMode.html#)!`)`
Called when an action mode has been started. The appropriate mode callback method will have already been invoked. Note that if you override this method you should always call through to the superclass implementation by calling super.onActionModeStarted(mode). If you override this method you*must*call through to the superclass implementation.
| | [Unit](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html) | [onAttachedToWindow](https://developer.android.com/reference/kotlin/android/app/Dialog#onAttachedToWindow())`()`
| | [Unit](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-unit/index.html) | [onBackPressed](https://developer.android.com/reference/kotlin/android/app/Dialog#onBackPressed())`()`
Called when the dialog has detected the user's press of the back key. The default implementation simply cancels the dialog (only if it is cancelable), but you can override this to do whatever you want. If you target version[android.os.Build.VERSION_CODES#TIRAMISU](https://developer.android.com/reference/kotlin/android/os/Build.VERSION_CODES.html#TIRAMISU:kotlin.Int)or later, you should not use this method but register an[OnBackInvokedCallback](https://developer.android.com/reference/kotlin/android/window/OnBackInvokedCallback.html#)on an[OnBackInvokedDispatcher](https://developer.android.com/reference/kotlin/android/window/OnBackInvokedDispatcher.html#)that you can retrieve using[getOnBackInvokedDispatcher()](https://developer.android.com/reference/kotlin/android/app/Dialog#getOnBackInvokedDispatcher()). You should also set`android:enableOnBackInvokedCallback="true"`in the application manifest. Alternatively, you can use`androidx.activity.ComponentDialog#getOnBackPressedDispatcher()`for backward compatibility.

Called when a generic motion event was not handled by any of the views inside of the dialog. Generic motion events describe joystick movements, mouse hovers, track pad touches, scroll wheel movements and other input events. The[source](https://developer.android.com/reference/kotlin/android/view/MotionEvent.html#getSource())of the motion event specifies the class of input that was received. Implementations of this method must examine the bits in the source before processing the event. The following code example shows how this is done. Generic motion events with source class[android.view.InputDevice#SOURCE_CLASS_POINTER](https://developer.android.com/reference/kotlin/android/view/InputDevice.html#SOURCE_CLASS_POINTER:kotlin.Int)are delivered to the view under the pointer. All other generic motion events are delivered to the focused view. See[View.onGenericMotionEvent(MotionEvent)](https://developer.android.com/reference/kotlin/android/view/View.html#onGenericMotionEvent(android.view.MotionEvent))for an example of how to handle this event.

Restore the state of the dialog from a previously saved bundle. The default implementation restores the state of the dialog's view hierarchy that was saved in the default implementation of[onSaveInstanceState()](https://developer.android.com/reference/kotlin/android/app/Dialog#onSaveInstanceState()), so be sure to call through to super when overriding unless you want to do all restoring of state yourself.

Called when a touch screen event was not handled by any of the views under it. This is most useful to process touch events that happen outside of your window bounds, where there is no view to receive it.
| | [Boolean](https://kotlinlang.org/api/latest/jvm/stdlib/kotlin/-boolean/index.html) | [onTrackballEvent](https://developer.android.com/reference/kotlin/android/app/Dialog#onTrackballEvent(android.view.MotionEvent))`(`event:` `[MotionEvent](https://developer.android.com/reference/kotlin/android/view/MotionEvent.html#)`)`
Called when the trackball was moved and not handled by any of the views inside of the activity. So, for example, if the trackball moves while focus is on a button, you will receive a call here because buttons do not normally do anything with trackball events. The call here happens*before*trackball movements are converted to DPAD key events, which then get sent back to the view hierarchy, and will be processed at the point for things like focus navigation.
