std-getcorner | ![]() |
STD-GETCORNER is basically the same as (INITGET ...) (GETCORNER ...),
If a lisp function given at the prompt returns a valid type this one is accepted.
The additionally needed INITGET initialization and default value check may be omitted, thus leading to easier looping code.
If the default argument is given (and it is not nil and the flag contains no bitvalue 1), then empty input is allowed as well.
flag: integer, same as the INITGET flag or nil
kwd: a initget-like string or a list of strings or nil
msg: a string to be displayed as a prompt or nil.
def: a default value as number, either interpreted as radians (0-2ð) or degrees (0-360) or nil
bpt: a point from which the highlighted box is drawn, relative to the actual UCS.
Either the default value or any point entered by the user.
Interrupts the program flow, prints the formatted message and waits for user input.
