.. currentmodule:: dialog pythondialog-specific exceptions ================================ Class hierarchy --------------- Here is the hierarchy of notable exceptions raised by this module: | :exc:`error` | :exc:`ExecutableNotFound` | :exc:`BadPythonDialogUsage` | :exc:`PythonDialogSystemError` | :exc:`PythonDialogOSError` | :exc:`PythonDialogIOError` (should not be raised starting from Python 3.3, as :exc:`IOError` becomes an alias of :exc:`OSError`) | :exc:`PythonDialogErrorBeforeExecInChildProcess` | :exc:`PythonDialogReModuleError` | :exc:`UnexpectedDialogOutput` | :exc:`DialogTerminatedBySignal` | :exc:`DialogError` | :exc:`UnableToRetrieveBackendVersion` | :exc:`UnableToParseBackendVersion` | :exc:`UnableToParseDialogBackendVersion` | :exc:`InadequateBackendVersion` | :exc:`PythonDialogBug` | :exc:`ProbablyPythonBug` As you can see, every exception *exc* among them verifies:: issubclass(exc, error) so if you don't need fine-grained error handling, simply catch :exc:`error` (which will probably be accessible as :exc:`dialog.error` from your program) and you should be safe. .. versionchanged:: 2.12 :exc:`PythonDialogIOError` is now a subclass of :exc:`PythonDialogOSError` in order to help with the transition from :exc:`IOError` to :exc:`OSError` in the Python language. With this change, you can safely replace ``except PythonDialogIOError`` clauses with ``except PythonDialogOSError`` even if running under Python < 3.3.
