Hi. I am thinking to use this nice feature for displaying some country flags and doing the relative choice.
I just copied the code from Ilan example.
The difference is that I haven't put the button on a panel, but directly on activity. (In my code the "btn" button is named "Lingua").
My code is hereunder, followed by the log with the error. The program, anyway, works.
Any hint? Thanks in advance.
Sub Globals
Private splight As SpotLight
Private Lingua As Button
End Sub
Sub Activity_Create(FirstTime As Boolean)
Activity.LoadLayout("Main")
'Create Spotlight Menu
Dim Italia,England,Russia As Bitmap ' used alwasy same jpg for the flags, just experiment
Italia.Initialize(File.DirAssets,"italia.jpg")
England.Initialize(File.DirAssets,"italia.jpg")
Russia.Initialize(File.DirAssets,"italia.jpg")
splight.Initialize(Me,"splight",10%y,False,False,True,Lingua,Activity)
splight.additem("Italia", Colors.Black,18,Italia)
splight.additem("England",Colors.Black,18,England)
splight.additem("Russia", Colors.Black,18,Russia)
End Sub
Sub Activity_Resume
End Sub
Sub Activity_Pause (UserClosed As Boolean)
End Sub
Sub Lingua_Click
splight.show
End Sub
Sub Lingua_LongClick
Lingua_Click
End Sub
