public class Dialog
extends UIRequest
implements IContainer

A helper class that lets you build UIRequests easily so you can send them with your UICaller class. Just create an instance of this for the addressed user and add Simple Form Controls to it. This one specifically creates a Dialog, which is the typical interaction unit between applications and users. Dialogs take control of the whole interaction space (e.g. occupy the full screen) until they are dismissed by the application or another Dialog comes in front of them. Dialogs have two groups for Controls: The main Controls group is for any kind of control. The Submits group is only for Submits intended to end the dialog or lead to new dialogs.

Example: Creating a dialog for selecting a light from a list and have commands for turning it on and off.

Dialog d=new Dialog(user,"Light interface");

Out out=new Out("-","Select one of the following lights");

d.add(out);

SelectOne list=new SelectOne(LIST_URI, "Lights");

list.setOptions(new String[]{"ligth1","light2","light3"});

d.add(list);

SubmitCmd s1=new SubmitCmd(SUBMIT_ON,"Turn On");

d.addSubmit(s1);

SubmitCmd s2=new SubmitCmd(SUBMIT_OFF,"Turn Off");

d.addSubmit(s2);

caller.sendUIRequest(d);

Notice that Simple Form Controls will be rendered in the same order as they are added. Once they are added they can no longer be modified, so set all their properties before adding them to the Dialog. Take into account however that Simple Group controls need to be added to the Dialog BEFORE other controls can be added to those Groups.

This is not necessarily faster nor better than the usual way of doing it with Form and UIRequest. It's just an alternative way that might help those less familiarized with universAAL.

Constructor Detail

Dialog

public Dialog(User user,
              String title)

Use this helper class to create a UIRequest that is easy to use. This Dialog extends UIRequest so you can use it with a UICaller. Default values are used for priority (low) and privacy (insensible).

Parameters:

user - The user to which the request is addressed.

title - The title of the Dialog.

Dialog

public Dialog(User user,
              String title,
              Resource root)

Use this helper class to create a UIRequest that is easy to use. This Dialog extends UIRequest so you can use it with a UICaller. This constructor can get a root Resource from which references to Controls can be reused. When creating a Form Control, pass it the property path in the root Resource to the right value and it will be set as initial value for that Control. Default values are used for priority (low) and privacy (insensible).

Parameters:

user - The user to which the request is addressed.

title - The title of the Dialog.

root - The Resource to use as root for the contained Form Controls.

Dialog

public Dialog(User user,
              String title,
              LevelRating priority,
              PrivacyLevel privacy)

Use this helper class to create a UIRequest that is easy to use. This Dialog extends UIRequest so you can use it with a UICaller.

Parameters:

user - The user to which the request is addressed.

title - The title of the Dialog.

priority - Set a custom priority for the Dialog.

privacy - Set the required privacy level for the Dialog.

Parameters:

user - The user to which the request is addressed.

title - The title of the Dialog.

root - The Resource to use as root for the contained Form Controls.

priority - Set a custom priority for the Dialog.

Method Detail

add

public String[] add(Control ctrl)

Description copied from interface: IContainer

Add the given Simple Control UI element to this container. Once the control is added it cannot be modified. Controls are renedered in the same order they are added. Controls that are Containers and can add elements as well, like Group or Repeat, must be added BEFORE other controls can be added to them. Controls that need references, like Inputs (with property paths), or Submits (with IDs) will be given an automatic reference if none was set. This reference will be returned by this method, in the form of an Array of Strings representing the reference: a Path for Inputs, or a single String for Submits IDs.

Specified by:

add in interface IContainer

Parameters:

ctrl - The Simple Control UI element to be added.

Returns:

The Array of Strings representing the reference Property Path for Input Controls, or with a single String for Submits IDs.

addSubmit

public String addSubmit(SubmitCmd ctrl)

Add a Submit Form Control to the Submit group of the Dialog. Submit group is for Submits that end the dialog or lead to new dialogs.

Parameters:

ctrl - The Submit to add

Returns:

The String representing the ID to be used to identify the Submit in the response.

addHidden

public void addHidden(String ref,
                      Object hidden)

Add a hidden object so it is sent within the UI request, but not shown to the user. When the UI response is being handled by the UI caller, this hidden input can be retrieved by calling uiresponse.getUserInput(new String[]{ref}); , being ref the one you used in this method.

Parameters:

ref - The reference you will use to access the hidden object later from the response

hidden - The object you want to hide

addExtra

public void addExtra(String property,
                     Object extra)

Add an extra property to the form used in this UI request. Extra properties may be used by I/O Handlers to allow the developer to fine-tune things like the layout. The equivalent in native API is to call setProperty() on a Form object. Use this only as recommended by the Handler you intend to use, since it is the Handler the one who will interpret the property.

Parameters:

property - The property of a Form that a certain Handler will inspect for its own purposes.

extra - The value to be set into the property.
