Display on top

[karq]

Hey,

so, I'm trying to make a notifier for my app. It should popup the main GUI on screen(on top) when some time is reached. I know that I have to use a timer for that, but how can I display my swing gui on top when time is reached?

gui.setVisibilite(true);?????

What is is Visibilite? I think you mean. gui.setVisible(true);

Read the API doc for the JFrame and the Window classes for methods that may do what you want.

yes that, sorry my english isnt very good.

You can simply adapt you code to make visible or invisible your JFrame by using setVisible(boolean) method. Something like a...

if(currentTime==(time+a))
{
frame.setVisible(true);
}

if(currentTime==(time+b))
{
frame.setVisible(false);

}

Thanks, got notify working.

But now I have another problem, When I start the app the notify class will be loaded. When I change the notify time in the file, then I have to restart my app to get that new time working.

So is there a way to self-restart my app or a way that updates the timer so that it uses that new time?

When I change the notify time in the file, then I have to restart my app to get that new time working.

How does the app know that the notify time in a disk file has been changed?
Does it read the file to get the time when it starts?

Can you explain a bit more about how your app works?

It reads the file when app starts. When I make changes(set new notify time) the notify class dosent know that I have made changes so I have to restart my app to read that file again.

[Norm]

So if you want you app to recognize that the file has changed without user prompting, you will need the app to capture the date last modified for the file and periodically test the file to see if the date has changed. Another place to use a Timer.

I'm stuck again. I made a timer for renewing the time. I know that I cant return something from a void method. So how can I fix it?

Here is a sample code

//Recheck time file for changes
    private Date checkFile(){
    
        int delay = 0;
        int subseq = 1000;

        //Recheck time file for changes
        Timer CheckTimer = new Timer();
        
        //Checked date
        Date newdate = null;

        //Scheduled time file check
        CheckTimer.scheduleAtFixedRate(new TimerTask() {
           
            public void run() {  <--VOID

                   newdate = DateForTimer();   <--HAVE TO RETURN THIS?!?!+
                   

            }
             
        },delay,subseq);
    
        //Return newdate
        return newdate
        
    
    }

Call a method in the surrounding class and pass the value to it.

I just dont get it. Made a FileWatcher what tracks modifications in the time file.
GTimerRunning returns false when the timer file is modified. But now I dont know how to use that boolean to restart the notification timer, I used another timer that
if(GTimerRunning == false){ GTimerRunning = true and run notification timer}.

But it didnt work out as I hoped.

So now I have this code and I dont know how to get it working.

public Notify(){
//Check time file for modifications
        TimerTask task = new FileWatcher(new File("notify.dat")){

            protected void Changes(){

                GTimerRunning = false;

            }

        };

        //Modification timer
        Timer ModiTimer = new Timer();
        ModiTimer.schedule(task,0, 1000);

        //Display main GUI when time is reached
        Timer TimerGUI = new Timer();

        TimerGUI.scheduleAtFixedRate(new TimerTask() {
                    public void run() {

                         dis.setVisible(true);


                    }
        },RenewDate,fonce_per_day);

}

Can you make a small, complete, executable program that demos your problem?
