  1. WaveMaker Visual AJAX Studio 4.0 Training Pages, Layers and Navigation

  2. What are Pages • A single addressable unit that allows you to arrange and display a group of widgets. • You can navigate from Page to Page • All widgets on a Page share the same scope • When a new Page is loaded the current page is destroyed and a new page is fetched from the sever with a new context. • Used to logically group functionality • Makes team development easier 

  3. How to Create a New Page • Under Create  Page or Under the Page Tools Menu you can: • Create a new Page • Save the current Page • Save the current Page As • Import a Page from another project • Set as Home Page ( the first page to load when the application is run • Delete a Page • To open a Page • Select the Go to Page Icon you will see a list of pages • Selecting a page will load it into the canvas

  4. Navigating to a Page • Add a New Navigation • gotoPage2 • Scoping • Page Level Scoping • The navigation is only available to the current page • Project Level Scoping • The navigation is available from any page anytime

  5. Calling the Navigation Service • Add a Button widget • Set the onClick event to execute the navigation • When the new the Page if you want to return to the calling page you must create another Navigation

  6. Using Pages as SubPages • From the Common tab of the Palette, add a PageContainer widget • In the Properties Editor, must set the pageName to display the subpage • From the Pages tab of the Palette, add the desired subpage • Creates a PageContainer with the pageName set

  7. Using Pages as SubPages • Page Container is added to the current page • Defines the area where a subpage will be displayed • On the Canvas, the subpage is displayed with cross marks through it • Service calls and data are not shared between pages and subpages unless they are scoped globally.

  8. What are Layers • Layers allow you to hide and show groups of widgets all on the same page. • Example: Tabs and Accordions • Layers are addressable and navigable • All layers are part of the same logical page • They share local variables • A page can contain many layers that can be dynamically displayed or hidden.

  9. How to add Layers to a Page • From the Palette select one of the following widgets • Layers – no visual clues that other layers exist; users navigate via events, clicking a button or link • Tabs – each layer has a titled tab; users can navigate through layers by clicking tabs • Accordion – each titled layer is expandable and collapsible; users can navigate through layers by clicking the arrow

  10. Layers Container • Has 1 more layers • Container Properties • Showing: is the layer visible • Disable: is the layer available to navigate to • defaultLayer – specify which layer to show upon rendering • layersType – specify style of Layers • Layers, Tabs, Accordion • Can be modified without changing functionality • add – adds a new layer to the Layers container

  11. Layers Container Events • Layers Events • oncanchange - fires when Layers widget is about to change the active layer • can be used to prevent navigation to another layer until some logic is performed • onchange – fires after Layers widgets changes the active layer

  12. Individual Layer • Within the Layers container are individual layers on which you add widgets • Once a layer is added you can use the properties to configure • caption – title displayed on Tab or Accordion menu; not shown on Layers • moveNext – move the current layer down in the Layers container • movePrevious – move the current layer up in the Layers container

  13. Layer Events • Layer Events • onShow – fires when Layer becomes active layer • Allows you to execute logic just before displaying a layer.

  14. Navigating to a Layer • Add a New Navigation • gotoLayer1 • Scoping • Page Level Scoping • The navigation is only available to the current page • Project Level Scoping • The navigation is available from any page anytime

  15. Setting Navigation Properties • Navigation Properties • Name – human readable name set by default, but can be changed • Configure – allows you to change the Page or Layer to navigate to • Queue – ability to automatically call additional service calls once the navigation has been completed. • Example: gotoPage1 then gotoLayer3

  16. Understanding Navigation Events Navigation Events onBeforeUpdate – fires just before the ServiceCall is made onResult – fires whenever a service returns, whether the service returned successfully or reported an error. onSuccess– fires whenever a service returns successfully. onError– fires whenever a service reports an error.
