2. Interfaces

2.1. TVInfoManagerObject

The TVInfoManagerObject interface defines what is instantiated in the tizen object. 
  [NoInterfaceObject] interface TVInfoManagerObject {
    readonly attribute TVInfoManager tvinfo;
  };
  Tizen implements TVInfoManagerObject;

Since: 2.4

There is a tizen.tvinfo object that allows accessing the functionality of the TVInfo API.

2.2. TVInfoManager

The TVInfoManager interface provides the functionalities to get setting values provided by Tizen TV. 
  [NoInterfaceObject] interface TVInfoManager {
    CaptionValue getCaptionValue(CaptionInfoKey key) raises(WebAPIException);
    long addCaptionValueChangeListener(CaptionInfoKey key, CaptionValueChangeCallback callback) raises(WebAPIException);
    void removeCaptionValueChangeListener(long watchId) raises(WebAPIException);
  };

Since: 2.4

Methods

getCaptionValue
Method returns the value for corresponding caption menu key. 
CaptionValue getCaptionValue(CaptionInfoKey key);

Since: 2.4

Return value:

    CaptionValue: CaptionValue value for given caption menu key

Exceptions:

  • WebAPIException

    • with error type TypeMismatchError, if the input parameter is not compatible with the expected type.

    • with error type UnknownError in any other error case.

Code example:

console.log("Caption menu turned on: " +
            (tizen.tvinfo.getCaptionValue("CAPTION_ONOFF_KEY") === "CAPTION_ON"));
addCaptionValueChangeListener
Adds a listener to be called when given caption menu key value changes. 
long addCaptionValueChangeListener(CaptionInfoKey key, CaptionValueChangeCallback callback);

Since: 2.4

Parameters:

  • key: Caption menu key which changes will be observed by this listener
  • callback: Callback method to be invoked when the value changes

Return value:

    long: long Subscription identifier

Exceptions:

  • WebAPIException

    • with error type TypeMismatchError, if the input parameter is not compatible with the expected type.

    • with error type InvalidValuesError, if any of the input parameters contain an invalid value.

    • with error type UnknownError in any other error case.

Code example:

var id = tizen.tvinfo.addCaptionValueChangeListener("CAPTION_ONOFF_KEY", function(value)
{
  console.log("Caption menu state changed: " + value);
});
removeCaptionValueChangeListener
Removes a listener. 
void removeCaptionValueChangeListener(long watchId);

Since: 2.4

Calling this function has no effect if there is no listener with given id.

Parameters:

  • watchId: Identifier of the subscription returned by addCaptionValueChangeListener()

Exceptions:

  • WebAPIException

    • with error type UnknownError, in any other error case.

Code example:

var id = tizen.tvinfo.addCaptionValueChangeListener("CAPTION_ONOFF_KEY", function() {});
tizen.tvinfo.removeCaptionValueChangeListener(id);

2.3. CaptionValueChangeCallback

The CaptionValueChangeCallback interface specifies event callback for getting notified when event occurs. 
  [Callback=FunctionOnly, NoInterfaceObject] interface CaptionValueChangeCallback {
    void onchanged(CaptionInfoKey key, CaptionValue value);
  };

Since: 2.4

Methods

onchanged
Called when the caption menu value changes. 
void onchanged(CaptionInfoKey key, CaptionValue value);

Since: 2.4

Parameters:

  • key: Watched key.
  • value: New value of watched key.
