:mod:`fl` --- FORMS library for graphical user interfaces
|
|
=========================================================
|
|
|
|
.. module:: fl
|
|
:platform: IRIX
|
|
:synopsis: FORMS library for applications with graphical user interfaces.
|
|
:deprecated:
|
|
|
|
|
|
.. deprecated:: 2.6
|
|
The :mod:`fl` module has been removed in Python 3.
|
|
|
|
|
|
.. index::
|
|
single: FORMS Library
|
|
single: Overmars, Mark
|
|
|
|
This module provides an interface to the FORMS Library by Mark Overmars. The
|
|
source for the library can be retrieved by anonymous ftp from host
|
|
``ftp.cs.ruu.nl``, directory :file:`SGI/FORMS`. It was last tested with version
|
|
2.0b.
|
|
|
|
Most functions are literal translations of their C equivalents, dropping the
|
|
initial ``fl_`` from their name. Constants used by the library are defined in
|
|
module :mod:`FL` described below.
|
|
|
|
The creation of objects is a little different in Python than in C: instead of
|
|
the 'current form' maintained by the library to which new FORMS objects are
|
|
added, all functions that add a FORMS object to a form are methods of the Python
|
|
object representing the form. Consequently, there are no Python equivalents for
|
|
the C functions :c:func:`fl_addto_form` and :c:func:`fl_end_form`, and the
|
|
equivalent of :c:func:`fl_bgn_form` is called :func:`fl.make_form`.
|
|
|
|
Watch out for the somewhat confusing terminology: FORMS uses the word
|
|
:dfn:`object` for the buttons, sliders etc. that you can place in a form. In
|
|
Python, 'object' means any value. The Python interface to FORMS introduces two
|
|
new Python object types: form objects (representing an entire form) and FORMS
|
|
objects (representing one button, slider etc.). Hopefully this isn't too
|
|
confusing.
|
|
|
|
There are no 'free objects' in the Python interface to FORMS, nor is there an
|
|
easy way to add object classes written in Python. The FORMS interface to GL
|
|
event handling is available, though, so you can mix FORMS with pure GL windows.
|
|
|
|
**Please note:** importing :mod:`fl` implies a call to the GL function
|
|
:c:func:`foreground` and to the FORMS routine :c:func:`fl_init`.

Functions Defined in Module :mod:`fl`
|
|
-------------------------------------
|
|
|
|
Module :mod:`fl` defines the following functions. For more information about
|
|
what they do, see the description of the equivalent C function in the FORMS
|
|
documentation:
|
|
|
|
|
|
.. function:: make_form(type, width, height)
|
|
|
|
Create a form with given type, width and height. This returns a :dfn:`form`
|
|
object, whose methods are described below.
|
|
|
|
|
|
.. function:: do_forms()
|
|
|
|
The standard FORMS main loop. Returns a Python object representing the FORMS
|
|
object needing interaction, or the special value :const:`FL.EVENT`.
|
|
|
|
|
|
.. function:: check_forms()
|
|
|
|
Check for FORMS events. Returns what :func:`do_forms` above returns, or
|
|
``None`` if there is no event that immediately needs interaction.
|
|
|
|
|
|
.. function:: set_event_call_back(function)
|
|
|
|
Set the event callback function.
|
|
|
|
|
|
.. function:: set_graphics_mode(rgbmode, doublebuffering)
|
|
|
|
Set the graphics modes.
|
|
|
|
|
|
.. function:: get_rgbmode()
|
|
|
|
Return the current rgb mode. This is the value of the C global variable
|
|
:c:data:`fl_rgbmode`.
|
|
|
|
|
|
.. function:: show_message(str1, str2, str3)
|
|
|
|
Show a dialog box with a three-line message and an OK button.
|
|
|
|
|
|
.. function:: show_question(str1, str2, str3)
|
|
|
|
Show a dialog box with a three-line message and YES and NO buttons. It returns
|
|
``1`` if the user pressed YES, ``0`` if NO.
|
|
|
|
|
|
.. function:: show_choice(str1, str2, str3, but1[, but2[, but3]])
|
|
|
|
Show a dialog box with a three-line message and up to three buttons. It returns
|
|
the number of the button clicked by the user (``1``, ``2`` or ``3``).
|
|
|
|
|
|
.. function:: show_input(prompt, default)
|
|
|
|
Show a dialog box with a one-line prompt message and text field in which the
|
|
user can enter a string. The second argument is the default input string. It
|
|
returns the string value as edited by the user.
|
|
|
|
|
|
.. function:: show_file_selector(message, directory, pattern, default)
|
|
|
|
Show a dialog box in which the user can select a file. It returns the absolute
|
|
filename selected by the user, or ``None`` if the user presses Cancel.
|
|
|
|
|
|
.. function:: get_directory()
|
|
get_pattern()
|
|
get_filename()
|
|
|
|
These functions return the directory, pattern and filename (the tail part only)
|
|
selected by the user in the last :func:`show_file_selector` call.
|
|
|
|
|
|
.. function:: qdevice(dev)
|
|
unqdevice(dev)
|
|
isqueued(dev)
|
|
qtest()
|
|
qread()
|
|
qreset()
|
|
qenter(dev, val)
|
|
get_mouse()
|
|
tie(button, valuator1, valuator2)
|
|
|
|
These functions are the FORMS interfaces to the corresponding GL functions. Use
|
|
these if you want to handle some GL events yourself when using
|
|
:func:`fl.do_events`. When a GL event is detected that FORMS cannot handle,
|
|
:func:`fl.do_forms` returns the special value :const:`FL.EVENT` and you should
|
|
call :func:`fl.qread` to read the event from the queue. Don't use the
|
|
equivalent GL functions!
|
|
|
|
.. \funcline{blkqread}{?}
|
|
|
|
|
|
.. function:: color()
|
|
mapcolor()
|
|
getmcolor()
|
|
|
|
See the description in the FORMS documentation of :c:func:`fl_color`,
|
|
:c:func:`fl_mapcolor` and :c:func:`fl_getmcolor`.
|
|
|
|
|
|
.. _form-objects:
|
|
|
|
Form Objects
|
|
------------
|
|
|
|
Form objects (returned by :func:`make_form` above) have the following methods.
|
|
Each method corresponds to a C function whose name is prefixed with ``fl_``; and
|
|
whose first argument is a form pointer; please refer to the official FORMS
|
|
documentation for descriptions.
|
|
|
|
All the :meth:`add_\*` methods return a Python object representing the FORMS
|
|
object. Methods of FORMS objects are described below. Most kinds of FORMS

FORMS Objects
|
|
-------------
|
|
|
|
Besides methods specific to particular kinds of FORMS objects, all FORMS objects
|
|
also have the following methods:
|
|
|
|
|
|
.. method:: FORMS object.set_call_back(function, argument)
|
|
|
|
Set the object's callback function and argument. When the object needs
|
|
interaction, the callback function will be called with two arguments: the
|
|
object, and the callback argument. (FORMS objects without a callback function
|
|
are returned by :func:`fl.do_forms` or :func:`fl.check_forms` when they need
|
|
interaction.) Call this method without arguments to remove the callback
|
|
function.
|
|
|
|
|
|
.. method:: FORMS object.delete_object()
|
|
|
|
Delete the object.
|
|
|
|
|
|
.. method:: FORMS object.show_object()
|
|
|
|
Show the object.
|
|
|
|
|
|
.. method:: FORMS object.hide_object()
|
|
|
|
Hide the object.
|
|
|
|
|
|
.. method:: FORMS object.redraw_object()
|
|
|
|
Redraw the object.
|
|
|
|
|
|
.. method:: FORMS object.freeze_object()
|
|
|
|
Freeze the object.
|
|
|
|
|
|
.. method:: FORMS object.unfreeze_object()
|
|
|
|
Unfreeze the object.
|
|
|
|
FORMS objects have these data attributes; see the FORMS documentation:

This module defines symbolic constants needed to use the built-in module

:mod:`fl` (see above); they are equivalent to those defined in the C header file

``<forms.h>`` except that the name prefix ``FL_`` is omitted. Read the module
