public class View extends MobileLayoutPane
Glisten user interfaces are built using views, which are essentially named
MobileLayoutPanes
. To construct a View instance,
a developer simply calls the constructor and then begins to use the API
inherited from MobileLayoutPane, most notably
BorderPane.setTop(Node)
, BorderPane.setCenter(Node)
,
and BorderPane.setBottom(Node)
.
Layers
can be placed on top of a View by adding them to the
layers
list. By doing this, it is possible to present
popup cards and other context-specific information to users.
Developers create and add Views to an application using the MobileApplication
class. For this the method MobileApplication.addViewFactory(String, Supplier)
is called passing in the name of the View, which must be unique, and a View factory
which when called by Glisten, should return a new instance of this particular
View.
The most important view factory is the one that specifies the 'home view', which is
shown when the application first starts. For example, here is the code to create a
view factory for the home view:
MobileApplication.getInstance().addViewFactory(MobileApplication.HOME_VIEW, () -> {
// normal JavaFX code to create a scenegraph of nodes
Node homeViewContent = ...;
return new View(MobileApplication.HOME_VIEW, homeViewContent);
});
From the user interacting with this View a change to another View might be
desirable. To do this, developers should call MobileApplication.switchView(String)
or a similar method.
For more information about Views and how they fit into the overall Glisten
framework checkout the API documentation of the MobileApplication
class.
