Signal

GtkSvg::error

unstable since: 4.22

Declaration

void
error (
  GtkSvg* self,
  GError* error,
  gpointer user_data
)

Description [src]

Signals that an error occurred.

Errors can occur both during parsing and during rendering.

The expected error values are in the GtkSvgError enumeration, context information about the location of parsing errors can be obtained with the various gtk_svg_error functions.

Parsing errors are never fatal, so the parsing will resume after the error. Errors may however cause parts of the given data or even all of it to not be parsed at all. So it is a useful idea to check that the parsing succeeds by connecting to this signal.

Note

This signal is emitted in the middle of parsing or rendering, and if you handle it, you must be careful. Logging the errors you receive is fine, but modifying the widget hierarchy or changing the paintable state definitively isn’t.

If in doubt, defer to an idle.

Default handler:

The default handler is called after the handlers added via g_signal_connect().

Available since: 4.22

Parameters

error

Type: GError

The error.

The data is owned by the caller of the function.
