initialLayout
The initialLayout
component is a layout that will be displayed when no views are opened in the main view. This component can be useful when you need to show some default content, such as a logo or dashboard, before any other views are opened.

Basics
initialLayout
is a nested element of the appLayout
component.
To add a nested initialLayout element in Jmix Studio, select the appLayout element in the main view descriptor XML or in the Jmix UI structure panel and click on the Add→InitialLayout button in the Jmix UI inspector panel.

An example of defining initialLayout
in main-view.xml
:
<mainView xmlns="http://jmix.io/schema/flowui/main-view"
title="msg://MainView.title">
<appLayout>
<navigationBar .../>
<drawerLayout .../>
<initialLayout>
<image id="urlImage"
resource="https://www.jmix.io/uploads/framework_image_9efadbc372.svg"
width="100%"
height="100%"/>
</initialLayout>
</appLayout>
</mainView>
When added in XML, the root <initialLayout>
element effectively is VerticalLayout.
Alternatively, the StandardMainView
Java API can be used to set/get the initial layout:
-
getInitialLayout()
- returns the root component of the initial layout. -
setInitialLayout()
- sets a component that will be the initial layout.
Components inside initialLayout
can be injected into the MainView
, for example:
@ViewComponent
private JmixImage<Object> urlImage;
@Subscribe
public void onInit(final InitEvent event) {
urlImage.setSrc("https://www.jmix.io/uploads/framework_image_9efadbc372.svg");
urlImage.setWidth("100%");
urlImage.setHeight("100%");
}
@Subscribe(id = "urlImage", subject = "singleClickListener")
public void onUrlImageClick(final ClickEvent<JmixImage<?>> event) {
Notification.show("Clicked!");
}
