Incubator Popup for Flow is a server-side component of the incubator-popup web component for Vaadin 10. It provides a popup that can be bound to element by id, and be opened on clicking to target element. ### Usage After creating new Popup object it should be bound to a target element by calling the method `setFor(id)` with the id of the target element as parameter. Then after clicking on the target element, the popup will be opened. Clicking outside of the popup will close it. ``` Popup popup = new Popup(); popup.setFor("id-of-target-element"); Div text = new Div(); text.setText("element 1"); Div text2 = new Div(); text2.setText("element 2"); popup.add(text, text2); ``` If the parameter `closeOnClick` is set to `true`, the popup will be closed also after clicking on the popup. Opening and closing of the popup can be done programmatically by calling the methods `show()` and `hide()`. ``` Button button = new Button("Show/Hide"); button.addClickListener(e -> { if (popup.isOpened()) { popup.hide(); } else { popup.show(); } }); ``` Setting the parameter `opened` to `true` will open the popup. In case the popup is not yet rendered, it will be opened after rendering. ``` popup.setOpened(true); ```
