Method Detail

navigateBack

public void navigateBack()

This method navigates back in the history to the DialogPlace that has been visited before. In a web-application this can also be triggered by pressing the back button.

navigateForward

public void navigateForward()

This method navigates forward in the history. After DialogManager.navigateBack() was invoked, this method will go to the DialogPlace that has been visited before the invocation of DialogManager.navigateBack(). In a web-application this can also be triggered by pressing the forward button.

navigateTo

public void navigateTo(DialogPlace place)

This method opens the given DialogPlace and its according Dialog in the current ApplicationWindow. The current place is added to the navigation history.

Parameters:

place - is the DialogPlace identifying the Dialog to open.

getStartPlace

protected DialogPlace getStartPlace()

This method determines the start DialogPlace. If the application is started from a bookmark, this method will create the DialogPlace from this bookmark (in case of a web-application from the hash of the URL).

Specified by:

openInNewWindow

public ApplicationWindow openInNewWindow(DialogPlace place)

This method opens the given DialogPlace and its according Dialog in a new ApplicationWindow. The operation does not affect the current navigation history. In case of a web-application a new browser window (or tab) is opened that starts another instance of the client at the given place. In a native client a new window is opened with its own DialogManager instance and new instances of all Dialogs.

Parameters:

place - is the DialogPlace to open in the new window.

Returns:

the handle for the new window.

onNavigate

protected void onNavigate(String place)

This method gets called whenever the DialogPlace changes.
