The source for the +library can be retrieved by anonymous ftp from host +\samp{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 \samp{fl_} from their name. Constants used by +the library are defined in module \refmodule[fl-constants]{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 +\cfunction{fl_addto_form()} and \cfunction{fl_end_form()}, and the +equivalent of \cfunction{fl_bgn_form()} is called +\function{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. + +\strong{Please note:} importing \module{fl} implies a call to the GL +function \cfunction{foreground()} and to the FORMS routine +\cfunction{fl_init()}. + +\subsection{Functions Defined in Module \module{fl}} +\nodename{FL Functions} + +Module \module{fl} defines the following functions. For more +information about what they do, see the description of the equivalent +C function in the FORMS documentation: + +\begin{funcdesc}{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. +\end{funcdesc} + +\begin{funcdesc}{do_forms}{} +The standard FORMS main loop. Returns a Python object representing +the FORMS object needing interaction, or the special value +\constant{FL.EVENT}. +\end{funcdesc} + +\begin{funcdesc}{check_forms}{} +Check for FORMS events. Returns what \function{do_forms()} above +returns, or \code{None} if there is no event that immediately needs +interaction. +\end{funcdesc} + +\begin{funcdesc}{set_event_call_back}{function} +Set the event callback function. +\end{funcdesc} + +\begin{funcdesc}{set_graphics_mode}{rgbmode, doublebuffering} +Set the graphics modes. +\end{funcdesc} + +\begin{funcdesc}{get_rgbmode}{} +Return the current rgb mode. This is the value of the C global +variable \cdata{fl_rgbmode}. +\end{funcdesc} + +\begin{funcdesc}{show_message}{str1, str2, str3} +Show a dialog box with a three-line message and an OK button. +\end{funcdesc} + +\begin{funcdesc}{show_question}{str1, str2, str3} +Show a dialog box with a three-line message and YES and NO buttons. +It returns \code{1} if the user pressed YES, \code{0} if NO. +\end{funcdesc} + +\begin{funcdesc}{show_choice}{str1, str2, str3, but1\optional{, + but2\optional{, 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 +(\code{1}, \code{2} or \code{3}). +\end{funcdesc} + +\begin{funcdesc}{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. +\end{funcdesc} + +\begin{funcdesc}{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 \code{None} if the user +presses Cancel. +\end{funcdesc} + +\begin{funcdesc}{get_directory}{} +\funcline{get_pattern}{} +\funcline{get_filename}{} +These functions return the directory, pattern and filename (the tail +part only) selected by the user in the last +\function{show_file_selector()} call. +\end{funcdesc} + +\begin{funcdesc}{qdevice}{dev} +\funcline{unqdevice}{dev} +\funcline{isqueued}{dev} +\funcline{qtest}{} +\funcline{qread}{} +%\funcline{blkqread}{?} +\funcline{qreset}{} +\funcline{qenter}{dev, val} +\funcline{get_mouse}{} +\funcline{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 \function{fl.do_events()}. When a GL event is detected that +FORMS cannot handle, \function{fl.do_forms()} returns the special value +\constant{FL.EVENT} and you should call \function{fl.qread()} to read +the event from the queue.
