Availability: Macintosh.
The EasyDialogs module contains some simple dialogs for the Macintosh. All routines take an optional resource ID parameter id with which one can override the DLOG resource used for the dialog, provided that the dialog items correspond (both type and item number) to those in the default DLOG resource. See source code for details.
The EasyDialogs module defines the following functions:
"" is used). The text of
the ``OK'' and ``Cancel'' buttons can be changed with the ok and
cancel arguments. All strings can be at most 255 bytes long.
AskString() returns the string entered or None in case
the user cancelled.
1 for ``Yes'', 0
for ``No'' and -1 for ``Cancel''. The value of default (or
0 if default is not supplied) is returned when the
RETURN key is pressed. The text of the buttons can be changed with
the yes, no, and cancel arguments; to prevent a button
from appearing, supply "" for the corresponding argument.
0, indicating that an
indeterminate amount of work remains to be done), and label is
the text that is displayed above the progress bar itself.
sys.argv format, suitable for
passing as an argument to getopt.getopt(). addoldfile,
addnewfile, and addfolder are boolean arguments. When
nonzero, they enable the user to insert into the command line paths to
an existing file, a (possibly) not-yet-existent file, and a folder,
respectively. (Note: Option arguments must appear in the command line
before file and folder arguments in order to be recognized by
getopt.getopt().) Arguments containing spaces can be
specified by enclosing them within single or double quotes. A
SystemExit exception is raised if the user presses the
``Cancel'' button.
optionlist is a list that determines a popup menu from which the
allowed options are selected. Its items can take one of two forms:
optstr or (optstr, descr). When present,
descr is a short descriptive string that is displayed in the
dialog while this option is selected in the popup menu. The
correspondence between optstrs and command-line arguments is:
| optstr format | Command-line format |
|---|---|
x |
-x (short option) |
x: or x= |
-x (short option with value) |
xyz |
--xyz (long option) |
xyz: or xyz= |
--xyz (long option with value) |
commandlist is a list of items of the form cmdstr or
(cmdstr, descr), where descr is as above. The
cmdstrs will appear in a popup menu. When chosen, the text of
cmdstr will be appended to the command line as is, except that a
trailing ":" or "=" (if present) will be trimmed
off.
New in version 2.0.
