Hi,
Is it possible to include richer content (eg icons, buttons, html content) in the desktop notification - triggered by ClientSession.get().getDesktop().addNotification() - such as in a popup?
In the example from the page https://scout.bsi-software.com/widgets/?dl=widget-desktop I can see that you can include only simple text in the notification. But when, for example, I click "View source on GitHub" there, it displays notification "Opening a new window automatically was blocked by the browser" with an additional "Open manually" button. This would indicate that there is some method to add additional elements to the notification.

Hi Krzysztof
Yes, when you take a look at the JavaScript source-code in PopupBlockerHandler#showNotification, you'll see that a "variant" of DesktopNotification.js is created instead of the regular Notification:
notification = scout.create('DesktopNotification:PopupBlocker', {
parent: desktop,
linkUrl: linkUrl,
preserveOpener: this.preserveOpener
});
This instantiates the class PopupBlockerDesktopNotification.js, where the _render function creates the HTML you mentioned in your post.
In a Scout Java application you could use a @ModelVariant to mark a specific Notification class, like this:
@ModelVariant("Special")
class SpecialDesktopNotification extends DesktopNotification {
public SpecialDesktopNotification(IStatus status, long duration, boolean closable) {
super(status, duration, closable);
}
}
And add the notification like this:
DesktopNotification notification = new SpecialDesktopNotification(status, duration, closeable);
ClientSession.get().getDesktop().addNotification(notification);
In your *.ui.html project you need to add a JavaScript class "SpecialDesktopNotification.js" that extends DesktopNotification.js and register it in your module.js. Scout finds and instantiates this class by name-magic. In that class you can override the _render or _renderMessage function and implement whatever you need. A very simple approach could override _renderMessage and simply add the message from the status object as HTML, without encoding HTML as DesktopNotification.js does. Example:
scout.SpecialDesktopNotification.prototype._renderMessage = function() {
var html = scout.nvl(this.status.message, '');
this.$messageText.html(html);
};

Hi Krzysztof
You can pass a special "app link handler" to the constructor of your DesktopNotification instance. Something like this:
IStatus status = new Status(HTML.span("Click me").appLink("myRef").toHtml(), IStatus.INFO);
IDesktopNotification notification = new DesktopNotification(status, IDesktopNotification.INFINITE_DURATION, true, true, ref -> MessageBoxes.createOk().withBody("You clicked this link: " + ref).show());
desktop.addNotification(notification);
Regards,
Beat
