--- title: PopupView order: 29 layout: page --- [[components.popupview]] = [classname]#PopupView# ifdef::web[] [.sampler] image:{live-demo-image}[alt="Live Demo", link="http://demo.vaadin.com/sampler/#ui/structure/popup-view"] endif::web[] The [classname]#PopupView# component allows opening a pop-up view either by clicking on a link or programmatically. The component has two representations: a minimized textual representation and the popped-up content. The view can contain any components. The view closes automatically when the mouse pointer moves outside the view. In the following, we have a popup view with a text field and a button that opens automatically when the user clicks on a "Open the popup" link: [source, java] ---- // Content for the PopupView VerticalLayout popupContent = new VerticalLayout(); popupContent.addComponent(new TextField("Textfield")); popupContent.addComponent(new Button("Button")); // The component itself PopupView popup = new PopupView("Pop it up", popupContent); layout.addComponent(popup); ---- If the textual minimized representation is not given (a null is given), the component is invisible in the minimized state. The pop-up can be opened programmatically by calling [methodname]#setPopupVisible(true)#. For example: [source, java] ---- // A pop-up view without minimalized representation PopupView popup = new PopupView(null, new Table(null, TableExample.generateContent())); // A component to open the view Button button = new Button("Show table", click -> // Java 8 popup.setPopupVisible(true)); layout.addComponents(button, popup); ---- When the pop-up is opened or closed, a [classname]#PopupVisibilityEvent# is fired, which can be handled with a [interfacename]#PopupVisibilityListener# added with [methodname]#setPopupVisibilityListener()#. [source, java] ---- // Fill the pop-up content when it's popped up popup.addPopupVisibilityListener(event -> { if (event.isPopupVisible()) { popupContent.removeAllComponents(); popupContent.addComponent(new Table(null, TableExample.generateContent())); }}); ---- [[components.popupview.css]] == CSS Style Rules [source, css] ---- .v-popupview {} .v-overlay-container { .v-popupview-popup { .popupContent { } } } ---- In minimalized state, the component has [literal]#++v-popupview++# style. When popped up, the pop-up content is shown in a [literal]#++v-popupview-popup++# overlay element under the [literal]#++v-overlay-container++#, which is contains all floating overlays outside the component hierarchy.
