• setAllowPlaceholders

  public CreateScreenSettings setAllowPlaceholders(java.lang.Boolean allowPlaceholders)

  Should Placeholders be rendered as placeholders? If property is not set actual components are created instead of the Placeholders.

  Parameters:

  allowPlaceholders - New allowPlaceholders value. Default value is null

  Returns:

  CreateScreenSettings instance, for chaining setter calls

• getAllowPlaceholders

  public java.lang.Boolean getAllowPlaceholders()

  Returns:

  Current allowPlaceholders value. Default value is null

• setClassSubstitutions

  public CreateScreenSettings setClassSubstitutions(java.util.Map classSubstitutions)

  Maps class names of widgets in the screen to new class names, so that if a widget would normally be constructed as an instance of a class, and that class is in the map, it's instead constructed as an instance of the new class.

  Parameters:

  classSubstitutions - New classSubstitutions value. Default value is null

  Returns:

  CreateScreenSettings instance, for chaining setter calls

  See Also:

  RPCManager.createScreen(java.lang.String)

• getClassSubstitutions

  public java.util.Map getClassSubstitutions()

  Maps class names of widgets in the screen to new class names, so that if a widget would normally be constructed as an instance of a class, and that class is in the map, it's instead constructed as an instance of the new class.

  Returns:

  Current classSubstitutions value. Default value is null

  RPCManager.createScreen(java.lang.String)

• setClobberDataSources

  public CreateScreenSettings setClobberDataSources(java.lang.Boolean clobberDataSources)

  Should DataSources referenced by the screen clobber existing, globally-bound DataSources on the client when the screen is created? The default of false means that any DataSources defined in the screen will be discarded if they collide with existing, globally-bound DataSources.

  Note that here we consider a DataSource to be "globally bound" if it can be retrieved by ID using the method DataSource.get(), regardless of whether it's actually bound to the browser window object.

  Parameters:

  clobberDataSources - New clobberDataSources value. Default value is false

  Returns:

  CreateScreenSettings instance, for chaining setter calls

• getClobberDataSources

  public java.lang.Boolean getClobberDataSources()

  Should DataSources referenced by the screen clobber existing, globally-bound DataSources on the client when the screen is created? The default of false means that any DataSources defined in the screen will be discarded if they collide with existing, globally-bound DataSources.

  Note that here we consider a DataSource to be "globally bound" if it can be retrieved by ID using the method DataSource.get(), regardless of whether it's actually bound to the browser window object.

  Returns:

  Current clobberDataSources value. Default value is false

• setComponentSubstitutions

  public CreateScreenSettings setComponentSubstitutions(java.util.Map componentSubstitutions)

  Defines the map of new widget ids to existing class instances, or to new instances that will be of a different class. A substituted class instance is returned immediately from Class.create() without modification. Otherwise, the constructor for the new instance is run, but targeting the substituted class rather than the original.

  Note that where we return an existing instance, not even its Canvas.ID will be changed. An alternative is programmtic replacement using Layout.replaceMember().

  Parameters:

  componentSubstitutions - New componentSubstitutions value. Default value is null

  Returns:

  CreateScreenSettings instance, for chaining setter calls

  See Also:

  RPCManager.createScreen(java.lang.String)

• getComponentSubstitutions

  public java.util.Map getComponentSubstitutions()

  Defines the map of new widget ids to existing class instances, or to new instances that will be of a different class. A substituted class instance is returned immediately from Class.create() without modification. Otherwise, the constructor for the new instance is run, but targeting the substituted class rather than the original.

  Note that where we return an existing instance, not even its Canvas.ID will be changed. An alternative is programmtic replacement using Layout.replaceMember().

  Returns:

  Current componentSubstitutions value. Default value is null

  See Also:

  RPCManager.createScreen(java.lang.String)

• setDataContext

  public CreateScreenSettings setDataContext(DataContext dataContext)

  DataContext that will be provided to the top-level component as dataContext in the screen.

  To understand how dataContext is used to automatically populate DataBoundComponents, see Canvas.autoPopulateData.

  Parameters:

  dataContext - New dataContext value. Default value is null

  Returns:

  CreateScreenSettings instance, for chaining setter calls

• getDataContext

  public DataContext getDataContext()

  DataContext that will be provided to the top-level component as dataContext in the screen.

  To understand how dataContext is used to automatically populate DataBoundComponents, see Canvas.autoPopulateData.

  Returns:

  Current dataContext value. Default value is null

• setHtmlElement

  public CreateScreenSettings setHtmlElement(com.google.gwt.dom.client.Element htmlElement)

  Simplifies integrating a screen with an existing JavaScript app. Does the following:

  • Sets suppressAutoDraw: true
  • Sets Canvas.htmlElement of the screen's top widget to the DOM element
  • Sets the screen's top widget to have Canvas.position: "relative"
  • Draws the screen by calling Canvas.draw() on the top widget

  If you need to apply additional, custom configuration, for example setting Canvas.htmlPosition, then instead of using this property, you can call RPCManager.createScreen() with suppressAutoDraw: true, and then manually configure and draw the screen:

        CreateScreenSettings settings = new CreateScreenSettings();
        settings.setSuppressAutoDraw(true);
        Canvas screen = RPCManager.createScreen("My Screen", settings);
        screen.setHtmlElement(element);
        screen.setHtmlPosition(DrawPosition.REPLACE);
        screen.setPosition(Positioning.RELATIVE);
        screen.draw();
    

  Parameters:

  htmlElement - New htmlElement value. Default value is null

  Returns:

  CreateScreenSettings instance, for chaining setter calls
