Hi All, JCoverFlow is updated v1.6.

Added Event --> OnMouseClicked below an example:

B4X:
Sub CoverFlow_OnMouseClicked(Position As Int, Value As Object)

    If MainForm.RootPane.NumberOfNodes > 2  Then
        MainForm.RootPane.RemoveNodeAt(2)
    End If

    Dim x As Int = (MainForm.WindowWidth /2)-250
    MainForm.RootPane.AddNode(img,x,0,500,300)
    img2.Initialize("",Value)
    img.SetImage(img2)
    Log("Position = " & Position)
    Log("Value = " & Value)
End Sub

Hi @Giuseppe:

Trying to test your library but no luck !!

I've tested the B4J program with B4J versions form 2.80 to 3.61 and the main screen appears with menus but I can't see nothing in the coverflow panel setting the path to my images folder; I've tried with the options and nothin works (nor CoverFlow.ShowFromDirectoryChooser nor CoverFlow.ShowFromFolder nor CoverFlow.ShowFromFolder2("C:\\","Imatges") when selecting Populate and Show from Menu

I can run the program without errors but can't upload or see any images (Log (CoverFlow.Length)=0)

Any idea ?? Thanks !

(Windows 8.1 with java 8.45)

Hi
thanks for the update , i have a problem with the iCoverFlow.ItemsSize , since this is "CoverFlow.ItemsSize = 700dip" it will be a rectangle where other pictures have a different width , say 800x600 and the images look distorted :) , can we please specify this or keep the pictures ratio ?
thanks

Hi Giuseppe,

In first thank you for the update with Java 8 and your work.
I try to find the complete path returned by CoverFlow.ShowFromDirectoryChooser, seems wei can't get it ?
Or in another way, can we have a variable to put the last complete path instead of c:\ within the function?
But that means to have the path returned by the function. :D
It's a bit cumbersome to retrieve the complete path all the time.
Thanks.

Best regards
Laurent.
