Filtering

Properties

  • content : ViewCollection

    readonly

    Collection of the child views which creates balloon panel contents.

    See source

  • isActive : Boolean

    readonly observable

    Controls whether the sticky panel should be active.

    See source

  • isSticky : Boolean

    readonly observable

    Controls whether the sticky panel is in the "sticky" state.

    See source

  • limiterBottomOffset : Number

    readonly observable

    The offset from the bottom edge of limiterElement which stops the panel from stickying any further to prevent limiter's content from being completely covered.

    See source

    Defaults to 50

  • limiterElement : HTMLElement

    readonly observable

    The limiter element for the sticky panel instance. Its bounding rect limits the "stickyness" of the panel, i.e. when the panel reaches the bottom edge of the limiter, it becomes sticky to that edge and does not float off the limiter. It is mandatory for the panel to work properly and once set, it cannot be changed.

    See source

  • viewportTopOffset : Number

    readonly observable

    The offset from the top edge of the web browser's viewport which makes the panel become sticky. The default value is 0, which means the panel becomes sticky when it's upper edge touches the top of the page viewport.

    See source

    This attribute is useful when the web page has UI elements positioned to the top either using position: fixed or position: sticky, which would cover the sticky panel or vice–versa (depending on the z-index hierarchy).

    Defaults to 0

  • _contentPanel

    protected

    The panel which accepts children into content collection. Also an element which is positioned when isSticky.

    See source

  • _contentPanelPlaceholder

    protected

    A dummy element which visually fills the space as long as the actual panel is sticky. It prevents flickering of the UI.

    See source

  • _hasViewportTopOffset : Boolean

    protected readonly observable

    Set true if the sticky panel uses the viewportTopOffset, i.e. not _isStickyToTheLimiter and the viewportTopOffset is not 0.

    See source

  • _isStickyToTheLimiter : Boolean

    protected readonly observable

    Set true if the sticky panel reached the bottom edge of the limiterElement.

    See source

  • _limiterRect : Object

    protected

    The DOM bounding client rect of the limiterElement of the panel.

    See source

  • _marginLeft : String

    protected readonly observable

    Controls the margin-left CSS style of the panel.

    See source

  • _panelRect : Object

    protected

    The DOM bounding client rect of the element of the panel.

    See source

  • _checkIfShouldBeSticky()
