    changing Alert timeout from FOREVER to finite

    Hi,

    I am writing a Bluetooth-aware midlet, in which i'd like to use Alert to display inquiry messages. so initially, i'd like Alert to be displayed as modal (FOREVER), and then have bt-related code make it disappear once inquiry is done by doing

    setTimeout(1000) on already displayed Alert.

    entire sequence:

    alert.setTimeout(FOREVER);
    display.setCurrent(alert);
    //do some other stuff here
    //after a while call
    alert.setTimeout(1000);

    //alert should be dismissed in 1 sec?

    However, in my experience so far on Nokia 6600 and v0.31 s60 emulator, once the Alert is up, it stays up. Why is that and what can i do? Is it "legal" to change timeout value (and have it take effect) for an already displayed Alert? if not, how can i programmatically dismiss an Alert (other than by waiting for timeout to expire)?

    thanks

    Instead of trying to change the timeout just set another Displayable as the current screen. If you want to wait for one second you can either run a thread that waits and then changes the displayable, or make another alert and use setCurrent(Alert a, Displayable next) (the second option is easier but the first is better I think).

    the first one is a good (and now obvious solution). setting another alert while an alert already exists may not work however, because i remember reading that if one tries to do that (display one alert while another's displayed) an exception will be thrown..

    I haven't heard that. You can try.
    Even if it's true, since the first alert has it's timeout set to forever, you could just as well make it a Form.
