Method Detail

setViewport

public void setViewport(Viewport viewport)

Specified by:

setViewport in interface AppController

startIfNotAlreadyRunningThenFocus

public App startIfNotAlreadyRunningThenFocus(String appName,
                                             Location location)

This method can be called to launch an App and then delegate it to the LocationController. It should have the same effect as calling the LocationController directly.

Parameters:

appName - of the App to start.

location - holds information about the subApp to use and the parameters.

startIfNotAlreadyRunning

@Deprecated
public App startIfNotAlreadyRunning(String appName,
                                               Location location)

Deprecated.

This method is called to launch an app independent from the LocationController. It will not open in the Viewport. This is e.g. used to pass the App into a dialog and obtain app-specific information from outside the app. See MGNLUI-379.

Parameters:

appName - of the App to start.

location - holds information about the subApp to use and the parameters.
