Class AbstractApplicationController

java.lang.Object

com.softwareag.mobile.runtime.toolkit.AbstractApplicationController

All Implemented Interfaces:

IDialogDelegate, IResourceController, IPaneConfigDelegate

public abstract class AbstractApplicationController
extends java.lang.Object
implements IResourceController, IPaneConfigDelegate, IDialogDelegate

The AbstractApplicationController manages the inner life cycle of the application and is responsible for resource loading, pane configurations and transitions. The singleton instance can be accessed by getInstance() method. The AbstractApplicationController contains a lot of important methods which allow you to perform following operations:

• transition to a pane in the main window(see setView(nUIViewDisplay, int, int) and setViewController(AbstractViewController, int, int))
• change pane configuration (see changePaneConfiguration(nUIObject, PaneConfiguration, IPaneConfigDelegate, Hashtable) )
• manage particular pane(see showPane(int), hidePane(int) and isPaneVisible(int))
• open/close dialog window(see openDialog(AbstractAlertDialog) and closeDialog())
• open/close progress dialog window(see openProgressWindow() and closeProgressWindow())
• manage resources(see loadImage(String, int, int) and loadWWWResource(nUIObject, String, String, String))

Code snippet to change pane configuration:

 final AbstractApplicationController controller = AbstractApplicationController.getInstance();
 controller.changePangeConfiguration(null, myPaneConfiguration, controller new Hashtable());
 

It's also possible to set a new view controller without the TransitionStackController, for that use

 final AbstractViewController avc = ...;
 final int transitionStyle = nUIController.TRANSITION_FADE;
 final int paneId = 0;
 final AbstractApplicationController controller = AbstractApplicationController.getInstance();
 controller.setViewController(avc, transitionStyle, paneId);
