Usage

The base functionality concluded in the facet: HeaderButtonFacet, so it is possible to use a declarative way to define header buttons.

Add the following schema to your dialog screen:

xmlns:hb="http://schemas.headerbutton/headerbutton/0.1/headerbutton.xsd"

Then add headerButtons facet:

<facets>
    <hb:headerButtons id="headerButtons">
        <hb:button id="infoBtn"
                   icon="INFO"/>
    </hb:headerButtons>
</facets>

If you launch the application in the open dialog screen, you will see the following:

Now we can add a click listener to the "Info" button. For this, we can use the "Subscription" API. In the dialog screen controller, add the following code:

@Subscribe("headerButtons.infoBtn")
private void onCaptionBtnClickEvent(HeaderButton.ButtonClickEvent event) {
    notifications.create(Notifications.NotificationType.TRAY)
            .withCaption("Info button is clicked")
            .withDescription(event.getButtonId())
            .show();
}

Result:
