Step 11: Pages and PanelsLocate this document in the navigation structure

After all the work on the app structure it’s time to improve the look of our app. We will use two controls from the sap.m library to add a bit more "bling" to our UI. You will also learn about control aggregations in this step.

Figure 1: A panel is now displaying the controls from the previous steps

         <Page title="{i18n>homePageTitle}">

                        description="Hello {/recipient/name}"
We put both the input field and the button inside a containing control called sap.m.Page. The page provides an aggregation to 0..N other controls called content. It also displays the title attribute in a header section on top of the content. The page itself is placed into the pages aggregation of another control called sap.m.App which does the following important things for us:
  • It writes a bunch of properties into the header of the index.html that are necessary for proper display on mobile devices.

  • It offers functionality to navigate between pages with animations. We will use this soon.

In order to make the fullscreen height of the view work properly, we add the displayBlock attribute with the value true to the view. The actual content is wrapped inside a Panel control, in order to group related content.
# App Descriptor
appTitle=Hello World
appDescription=A simple walkthrough app that explains the most important concepts of SAPUI5

# Hello Panel
showHelloButtonText=Say Hello
helloMsg=Hello {0}
helloPanelTitle=Hello World

We add new key/value pairs to our text bundle for the start page title and the panel title.

  • Do not make implicit use of default aggregations but always declare the aggregation names explicitly in the view. In the example above, the content aggregation could also be omitted as the Panel control declares it as a default, but it makes the view harder to read.
