my question: How can i make the wheel to diappear?
in v0.22 you can set the visibility.
Lib is uploaded to Post #1

example:
B4X:
Sub btnhide_Click
    'Log(pg2.Visible)
    If pg2.Visible Then
        pg2.Visible = False
    Else
        pg2.Visible = True
    End If
End Sub

Pretty!

Could you make the inner circle like a clickable button that has a pressed effect? I want to use this as a round button that starts to spin when clicked and stops when the process is finished.

Cheers.

Clickable would be cool but it would need to have pressed states etc. I just solved it by adding a normal button with big rounded corners (half size of width and height).

Can you add height and width properties to the object so that I can resize my normal button precisely inside the progress wheel?

The end result is pretty good. Did not test transparancy yet on a photo background.

The middle white button is clickable and has borders etc. I will use the combined solution for scanning nearby objects (iBeacons etc.) When the button is clicked it will start spinning until all results are found.

Hi,
I need it for Subs long jobs
I initialize like:

ww.Initialize("ww")
ww.AddToParent(Activity,50%y-25dip,50%x-25dip,50dip,50dip)
ww.CircleRadius = 80
ww.RimWidth = 10
ww.SpinSpeed = 4
ww.spin
ww.Visible=False

But when I want to use
ww.visible=true
in a sub I get a java error Null pointer exception

whats wrong?

Another problem is, when I am , by ex, refreshing a customlistview it stops spinnig and then it is of no use ata all.

Thanks

What is computeScroll?
onClick (value As Object) - what value is generated?
