Hi @Erel;

i need using for old libs.

private B4Xcnvs as B4XCanvas

You can get it with:

'B4J and B4A
Sub GetNativeCanvas (b4x As B4XCanvas) As Canvas
   Dim jo As JavaObject = b4x
   jo = jo.GetFieldJO("cvs")
   If XUI.IsB4J Then Return jo.RunMethod("getObject", Null)
   Return jo
End Sub

'B4J and B4A
Sub GetNativeCanvas (b4x As B4XCanvas) As Canvas
   Dim jo As JavaObject = b4x
   Return jo.GetFieldJO("cvs").RunMethod("getObject", Null)
End Sub

sooo sorryy, GetNativeCanvas is OK.

I asked :
SETnativeCanvas

Maybe people need it.

A Set method is more problematic to add due to the way B4XCanvas is built.
