Properties accessible via the OptionsToolTip object allow you to assign tooltips to layout items and their images. Typically, you use the BaseLayoutItemOptionsToolTip.ToolTip property to provide a tooltip for a layout item. When hovering over the layout item's caption or image, this tooltip will be displayed. To provide a different tooltip for the layout item's image, use the BaseLayoutItemOptionsToolTip.IconToolTip property.
Tooltips are managed by a ToolTipController object (by default, by the Default ToolTipController, accessible via the DefaultToolTipController object). To manage tooltips using a different ToolTipController, assign a ToolTipController object to the LayoutControl.ToolTipController property.
