GtkStatusbar::get_context_id
int get_context_id(string context_description);
The GtkStatusbar sets up an internal array of
the messages that have been used, as they are being called. The
context_id is the array index position that a
given message holds.
As the message array is created on the fly, it is never the same
twice running. The messages that are displayed most frequently during
the status bar's lifetime will have low numbers, and a message that is
never called will not be added to the array. It is far more efficient
to use get_context_id() to
generate a context id for a message than it is to allocate your own
integer value.
The context_description is actually the text
string used in the statusbar label.
