    bottom : Number

  • activateShowListener( id )

    Activates an event listener associated with this balloon panel. See showListeners, activeShowListeners, deactivateShowListener, addShowListener, removeShowListener.

    Parameters

    id : Object

  • activateShowListeners()

    Activates all event listeners associated with this balloon panel. See showListeners, activeShowListeners, deactivateShowListeners, addShowListener, removeShowListener.

  • addShowListener( listener ) → Object

    Adds an event listener associated with this balloon panel. This listener will be activated on panel show and deactivated on panel hide. See showListeners, activeShowListeners, activateShowListeners, deactivateShowListeners.

    Parameters

    listener : Function

    A function that, if called, attaches the listener and returns the listener object.

    Returns

    Object

    An object containing the removeListener method that removes the listener from the collection.

  • attach( element, [ options ] )

    Places the balloon panel next to a specified element so the tip of the balloon's triangle touches that element. Once the panel is attached it gains focus.

    Parameters

    element : element

    The element to which the panel is attached.

    [ options ] : Object | element | Boolean

    Since 4.8.0 this parameter works as an options object.

    If a CKEDITOR.dom.element/Boolean instance is given, this parameter acts as an options.focusElement.

    Properties
    [ focusElement ] : element | Boolean

    The element to be focused after the panel is attached. By default the panel property of parts will be focused. You might specify the element to be focused by passing any CKEDITOR.dom.element instance. You can also prevent changing focus at all by setting it to false.

    [ show ] : Boolean

    Defines if the balloon panel should be shown after being attached.

    Defaults to true

    Overrides: CKEDITOR.ui.balloonPanel.attach

  • blur( [ focusEditor ] )

    Moves the focus back to the editor's editable.

    Parameters

    [ focusEditor ] : Boolean

    Whether the editor should be focused after blurring.

    Defaults to false

    Overrides: CKEDITOR.ui.balloonPanel.blur

  • build()

    Builds the balloon toolbar DOM representation.

    Overrides: CKEDITOR.ui.balloonPanel.build

  • deactivateShowListener( id )

    Deactivates an event listener associated with this balloon panel. See activateShowListener.

    Parameters

    id : Object

  • deactivateShowListeners()

    Removes all event listeners associated with this balloon panel. See activateShowListeners.

  • deregisterFocusable( element )

    Unregisters an element from editor's focus manager. See focusables.

    Parameters

    element : element

    An element to be registered.

    Sets the balloon panel title.

    Parameters

    title : String

    A new panel title.

    Parameters

  • _adjustElementRect( elementRect, editorRect )

    private

    This method will modify elementRect if the element is outside of editorRect. If it is outside, it is going to change it into a rectangle that is within editorRect.

    For example here elementRect is going to be changed into a very narrow rectangle (with unmodified height) representation within editorRect.
