Methods

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.

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

The beginUpdate and endUpdate methods allow you to apply several modifications to the component. After the beginUpdate method is called, the component does not update the UI until the endUpdate method is called. The usage of these methods prevents excessive component updating when you are changing multiple component settings at once.

The defaultOptions method is a static method supported by the widget class. The following code demonstrates how to specify default options for all buttons in the application executed on the iOS platform.

DevExpress.ui.dxButton.defaultOptions({ 
    device: { platform: "ios" },
    options: {
        text: "Click me"
    }
});

The beginUpdate and endUpdate methods allow you to apply several modifications to the component. After the beginUpdate method is called, the component does not update the UI until the endUpdate method is called. The usage of these methods prevents excessive component updating when you change multiple component setting at once.

Use this method to access other methods of the component.

After performing some external modifications that lead to the widget container's size or visibility change, the overlay's size and position may become invalid. In this instance, use the repaint() method to redraw the widget.

You can use the toggle(showing) method instead of show() and hide() methods. The only difference is that you specify whether to show or hide the widget passing true or false to the method parameter.
