Overlay
Contents
Learn how to use an overlay window control that widgets can inject their UI into.
Overview
The Overlay plugin provides an overlay window control that widgets can inject their UI into, accepting the HTML UI, placing it inside an overlay control, and displaying the UI onscreen in a uniform overlay window fashion. This prevents individual widgets from managing the overlay themselves. It also means that each widget's UI can be moved between different container types.
Overlay provides these benefits:
- Shows the UI in the center of the window.
- Open and close transition animations.
- No overlapping overlays. Only one at a time. Automatically managed by the Overlay plugin.
- Auto-recenter as the browser window size is changed.
- Automatic application of mobile styles when running in mobile mode.
Usage
Overlay is easy to use; you simply open and close it. When you call Overlay.open, you pass in the HTML content you want to show. If you call Overlay.open again while an overlay is already open, it will automatically close the previous overlay before showing yours (unless the previous overlay has reserved the overlay to prevent new overlays).
Customization
Overlay does not have customization options.
Mobile Support
Overlay automatically applies mobile CSS styles to its outer container to affect the content within the overlay view. It is up to the content inside the overlay view to dynamically change when the Genesys Widgets .cx-mobile CSS classname is applied to an outer container.
Configuration
Overlay does not have configuration options.
Localization
Overlay does not have localization options.
API commands
Once you've registered your plugin on the bus, you can call commands on other registered plugins. Here's how to use the global bus object to register a new plugin on the bus.
var oMyPlugin = window._genesys.widgets.bus.registerPlugin('MyPlugin');
oMyPlugin.command('Overlay.close');
open
Opens the provided HTML in an Overlay View. When successful, it returns back the HTML and a custom close event for you to subscribe to. This alerts you when your overlay instance has been closed. You can also make your overlay immutable so that new overlay instances don't close yours. Only your widget can close its overlay when immutable is set to true.
Example
oMyPlugin.command('Overlay.open', {
html: '<div>Template</div>',
immutable: false,
group: false
}).done(function(e){
// Overlay opens successfully
}).fail(function(e){
// Overlay failed to open
});

oMyPlugin.subscribe('Overlay.ready', function(e){});
