onAttachedToWindow

onContentChanged

abstract fun onContentChanged(): Unit

This hook is called whenever the content view of the screen changes (due to a call to Window.setContentView or Window.addContentView).

onCreatePanelMenu

abstract fun onCreatePanelMenu(
    featureId: Int, 
    menu: Menu
): Boolean

Initialize the contents of the menu for panel 'featureId'. This is called if onCreatePanelView() returns null, giving you a standard menu in which you can place your items. It is only called once for the panel, the first time it is shown.

You can safely hold on to menu (and any items created from it), making modifications to it as desired, until the next time onCreatePanelMenu() is called for this feature.

onCreatePanelView

abstract fun onCreatePanelView(featureId: Int): View?

Instantiate the view to display in the panel for 'featureId'. You can return null, in which case the default content (typically a menu) will be created for you.

onDetachedFromWindow

abstract fun onDetachedFromWindow(): Unit

Called when the window has been detached from the window manager. See View.onDetachedFromWindow() for more information.

onMenuItemSelected

abstract fun onMenuItemSelected(
    featureId: Int,

onPanelClosed

abstract fun onPanelClosed(
    featureId: Int, 
    menu: Menu
): Unit

Called when a panel is being closed. If another logical subsequent panel is being opened (and this panel is being closed to make room for the subsequent panel), this method will NOT be called.

onPointerCaptureChanged

open fun onPointerCaptureChanged(hasCapture: Boolean): Unit

Called when pointer capture is enabled or disabled for the current window.

onPreparePanel

abstract fun onPreparePanel(
    featureId: Int,

    type: Int
): ActionMode?
