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:
Displays a modal dialog with the message text str, which should be
at most 255 characters long. The button text defaults to ``OK'', but is
set to the string argument ok if the latter is supplied. Control
is returned when the user clicks the ``OK'' button.
Asks the user to input a string value via a modal dialog. prompt
is the prompt message, and the optional default supplies the
initial value for the string (otherwise "" 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.
Asks the user to input a string value via a modal dialog. Like
AskString(), but with the text shown as bullets. The
arguments have the same meaning as for AskString().
Presents a dialog with prompt question and three buttons labelled
``Yes'', ``No'', and ``Cancel''. Returns 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.
Displays a modeless progress-bar dialog. This is the constructor for the
ProgressBar class described below. title is the text
string displayed (default ``Working...''), maxval is the value at
which progress is complete (default 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.
Displays a dialog which aids the user in constructing a command-line
argument list. Returns the list in 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.
