4.5.2.1.26. PopupView

PopupView is a component that allows you to open a popup with a container. The popup can be opened by clicking on minimized value or programmatically. It can be closed by mouse out or by clicking on outside area.

A typical PopupView with hidden and visible popup is shown below:

Popup visible
Figure 19. Popup visible

The component is implemented for Web Client.

An example of a PopupView with minimized value retrieved from a localized message pack:

<popupView id="popupView"
           minimizedValue="msg://minimizedValue"
           caption="PopupView caption">
    <vbox width="60px" height="40px">
        <label value="Content" align="MIDDLE_CENTER"/>
    </vbox>
</popupView>

The inner content of the PopupView should be a container, for example BoxLayout.

            showNotification(event.isPopupVisible() ? "The popup is visible" : "The popup is hidden",
                NotificationType.HUMANIZED));
