4.1 X Error Classes

X errors are structured in the following class hierarchy:

Exception
 \_ error.XError
     \_ error.BadRequest
     \_ error.BadValue
     \_ error.BadAtom
     \_ error.BadMatch
     \_ error.BadAccess
     \_ error.BadAlloc
     \_ error.BadName
     \_ error.BadLength
     \_ error.BadImplementation
     \_ error.XResourceError
         \_ error.BadWindow
         \_ error.BadPixmap
         \_ error.BadCursor
         \_ error.BadFont
         \_ error.BadDrawable
         \_ error.BadColor
         \_ error.BadGC
         \_ error.BadIDChoice

All error objects has the following attributes:

code

The numeric error code

sequence_number

The sequence number of the failed request

resource_id

The bad resource id. For all the error.XResourceError this is a X resource object. For the other errors it is an integer, which for some errors might have no meaning

major_opcode

The major opcode for the failed request

minor_opcode

The minor opcode for the failed request. This will be zero for all base X11R6 request, but will be interesting for extension requests
