HOW TO: JProgressbar bean

[maarten]

1) go into designer and place a JProgessbar bean in your form
2) set name property to "progress"
3) create script with this code:

Code: Select all

elements.progress.visible = true // show  progress bar
elements.progress.orientation = 0 //(0=hor(default) 1=vertical)
elements.progress.stringPainted = true // enables showing strings inside the progres bar
elements.progress.string = "Starting script..."
elements.progress.value =0 // initialise value of the progres bar
elements.progress.minimum = 0 // min value allowed
elements.progress.maximum = 1000 //max value allowed

var percentage =0
for (var i=0 ; i<1000 ; i++)
{
   elements.progress.value = i
   //application.sleep(10)//simulates time needed to perform a loop
   percentage = elements.progress.getPercentComplete()
   elements.progress.string = "Looped through "+i+" records.Completed "+parseInt(percentage*100)+"%. "
   application.updateUI() //refresh user interface
}
elements.progress.string = "Script Completed"
application.beep()//signal when ended
application.sleep(1000) // bar remains visible 1 more second before disappearing
elements.progress.visible= false
plugins.dialogs.showInfoDialog( '',  'Script completed',  'OK')

Have fun.

Just to add a little:

1. When you set the indeterminate value to true you don't have to update the values, the progressbar will show a 'rolling' bar...

Cheers...

I think this was discussed before: I place the bean on my form, try your script, get an error and then realize, that the bean has disappeared from the elements in the method editor. I can still see it on the form but it cannot be addressed. This seems to happen every time you switch from designer to browse mode and back.

Was there something to do about?

Thanks.

What version do you use?

[patrick]

rc6

[maarten]

which OS are you on?
Does this occur in client and/or developer?

Can anyone else (using rc6) try to reproduce and report please?

Thanks in advance.

[patrick]

I am on Windows XP, using RC6, LAF Windows.

Maybe the porblem is the kind of form: I am trying to use this in a table view. First I placed the bean in the title header, then in the body part. No difference...

Thanks
Patrick

Maarten, I don't have an issue (rc6) but do work with mac os

[maarten]

hmm, unfortunately keeps working on my machine.
(rc6, W2000, java 1.4.1)
What java version are you running Patrick?

[patrick]

Java version 1.4.2_03-b02 (Windows XP)

Thanks for investigating.

Runs really good, but when I do it in ListView the progressbar is about 50 times slower than in RecordView. Why ?

I have asigned this method to an onAction of a button. When I klick the bar itM-4s running and when I klick again, while the bar is running it starts over from the beginning. How can I avoid this ?

Thanks

[IT2Be]

Do you set the value to 0 somewhere?

[WiderGates]

I donM-4t set the value to 0 other than explained.

Is it normal when you click on a button a second time while a method is running, the method is executed a second time ?

[patrick]

I still have that bean problem: you can see the bean on the form, but it doesn't appear under elements in the methode editor. Once I got it to work, though. But after switching between desinger and browse mode, it disappeared again...

[IT2Be]

Wider: If you execute the method like above you have your answers to both your questions:

1. By clicking the button you really start over at 0 again since the loop starts at 0 and the value of the progressbar is taken from the loop...
2. Yes clicking a button executes the method attached to it. If you don't want to do such a thing you should check if the button was clicked. You can do this by:

1. create a global variable globals.buttonwasclicked
2. when you start the method execute the following:

Code: Select all

if (globals.buttonwasclicked) return;
globals.buttonwasclicked = true

3. at the end of the loop:

Code: Select all

buttonwasclicked = false;
