New submission from Terry J. Reedy <tjre...@udel.edu>:
If one types 'int(' an int calltip is displayed. If one adds 'float(' then the
float calltip is displayed instead. If one adds '"3.1")', the int calltip is
restored. (Actually a new int calltip.) Finally, if one closes with ')', the
int calltip is removed.
If, after 'int(', one adds instead 'f(', where f has no accessible signature or
docstring and hence no calltip, the int calltip is dropped with no replacement.
When f is closed, the int calltip is not restored because open_calltip in
def refresh_calltip_event(self, event): # Bound to ')'.
if self.active_calltip and self.active_calltip.tipwindow:
self.open_calltip(False)
is not called because there is no existing calltip.
This issue is about somehow having the int calltip after the f call.
Possibilities.
1. Do not drop the int calltip when an inner call has none.
2. Give the inner call a fake calltip, something like "f(<unknown>". Again,
revise open_calltip.
3. Drop the outer calltip and set a 'nested_call flag in open_calltip and test
it with 'or' in refresh_calltip_event (and unset the flag -- conditionally?) to
restore it.
4. Add a calltip stack and test it for not empty in refresh_calltip_event.
Tal, any opinions on the desired behavior. I believe the #40511 revision
should make any of the above, with 1 and 2 being easiest and safest. A problem
with 3 and 4 is that the text cursor can be moved out of the call and the
calltip closed without the call being completed with ')'.
I want to add more tests first.
