React Common - utils - ui - Overlay - Methods

This section describes methods exposed by the DevExpress.ui.dxOverlay object.

baseZIndex(zIndex)

Specifies the base z-index for all overlay widgets.

import { OverlayTypes } from "devextreme-react/overlay"
Parameters:
zIndex:

Number

The z-index value.

The z-index of all overlay widgets located on a page is calculated based on the value passed to this method. Since an overlay widget is added, its z-index is increased by one relative to a previously added overlay widget.

The following example demonstrates how to call the method.

JavaScript
$(function(){
    DevExpress.ui.dxOverlay.baseZIndex(2000);
});

By default, the base z-index for all overlay widgets except Toast is 1500.

NOTE
The base z-index for Toast widgets is greater than the value specified by this method by 8000. For example, if you pass 2000 to the baseZIndex method, the Toast base z-index is 10000.

The method affects the following widgets.
