/**
|
|
23 |
* The <code>GlobalIndicators</code> is a class to handle the device global
|
|
24 |
* indicators. Global indicators are small icons that appear to the device
|
|
25 |
* status indicator area indicating for example the arrival of a new email or
|
|
26 |
* chat message. These indicators remain in the status indicator area even if
|
|
27 |
* the midlet is closed but rebooting the device will remove them, so the
|
|
28 |
* indicators are not fully persistent.<P>
|
|
29 |
*
|
|
30 |
* These global indicators are common and also used by the native applications.
|
|
31 |
* This means that at any time it is possible for any application to turn an
|
|
32 |
* indicator on or off. For that reason it is good practice to query the state
|
|
33 |
* of the indicator before setting the value.<P>
|
|
34 |
*
|
|
35 |
* There are also other indicators besides these <code>MAIL_INDICATOR</code> or
|
|
36 |
* <code>CHAT_INDICATOR</code> defined in this API. GlobalIndicators API allows
|
|
37 |
* to access those indicators too but the exact values of both the indicator and
|
|
38 |
* its value need to be given as accurate integer parameters (as some of those
|
|
39 |
* more complex indicators support a larger range of input parameters than just
|
|
40 |
* <code>INDICATOR_HIDE</code> or <code>INDICATOR_SHOW</code>).<P>
|
|
41 |
*
|
|
42 |
* Example of API usage:<P>
|
|
43 |
* <code>
|
|
44 |
* int retVal = GlobalIndicators.getGlobalIndicator(<BR>
|
|
45 |
* GlobalIndicators.MAIL_INDICATOR);<P>
|
|
46 |
* if(retVal != GlobalIndicators.INDICATOR_SHOW)<BR>
|
|
47 |
* {<BR>
|
|
48 |
* retVal = GlobalIndicators.setGlobalIndicator(<BR>
|
|
49 |
*   GlobalIndicators.MAIL_INDICATOR,<BR>
|
|
50 |
*   GlobalIndicators.INDICATOR_SHOW);<BR>
|
|
51 |
* }
|
|
52 |
* </code>
