ToolbarSpacer SAP SE Adds horizontal space between the items used within a {@link sap.m.Toolbar}. <b>Note:</b> <code>ToolbarSpacer</code> should not be used together with {@link sap.m.ToolbarLayoutData}. 1.16 sap.ui.core/Control Defines the width of the horizontal space. Note: Empty("") value makes the space flexible which means it covers the remaining space between toolbar items. This feature can be used to push next item to the edge of the toolbar.
