public abstract class AbstractDashboardWidget
extends com.vaadin.flow.component.orderedlayout.VerticalLayout

A small embeddable component that can be inserted into an AbstractDashboard. A DashboardWidget has two "faces": A cover that shows a summary or simply a title, and content, with the actual information to be shown. This can be seen as a Tile in a MS Windows Metro interface in most of the cases.

setActiveContent

public void setActiveContent(AbstractDashboardWidget.ActiveContent activeContent)

getTitle

public String getTitle()

setTitle

public void setTitle(String title)

getCoverComponent

public com.vaadin.flow.component.html.Div getCoverComponent()

setCoverComponent

public void setCoverComponent(com.vaadin.flow.component.html.Div coverComponent)

getContentComponent

public com.vaadin.flow.component.Component getContentComponent()

setContentComponent

public void setContentComponent(com.vaadin.flow.component.Component contentComponent)

flip

public void flip()

Flips the current displayed component. That is, instead of the cover component, the component widget will be displayed

launchAsNewWindow

public com.vaadin.flow.component.dialog.Dialog launchAsNewWindow()

Displays the contents of the content widget in a separate modal window.

The dialog.

createCover

public void createCover()

Creates the cover component. Note that implementors must set the coverComponent attribute and manage the respective events The default implementation creates a colored rectangle displaying the title of the widget without any style. For simple widgets it's recommended to use this implementation (that is, call super.createCover()) and set a style afterwards.

createContent

public abstract void createContent()
