fdesign - Forms Library User Interface Designer
fdesign [-xformoptions] [-options] [files]
is a GUI builder that helps in the construction of graphical user
interface in a WYSIWYG ("what you see is what you get") way by
allowing the user to directly manipulate various objects, such as buttons,
sliders and menus etc. Once a satisfactory UI is constructed, the user can
save the composed interface into a set of external files. Files with the
extension '.fd' contain all information about the objects and can be read in
again by fdesign
. The files with C code and header files when compiled
and linked against the Forms Library
, generate code that at run-time
constructs the exact same interface as the ones seen within fdesign
A variety of output languages is possible via external filters. As of this
writing, C, perl, ada95, Fortran, pascal, and PostScript output filters are
known to exist.
accepts all standard Forms Library
command line options as
well as the following:
- Prints a brief summary of all command line options. This
option does not require a connection to the X server.
- Prints the current version of fdesign and
- -geometry geom
- Specifies the prefered size and location of main working
area in which the UI is to be constructed.
- -convert fdfile-list
- This option prevents fdesign from attempting to make
a connection to the X server. The file list following this flag is
converted to C code directly.
- -dir destdir
- output any converted files in destdir.
- -unit pixel|point|mm|cp|cmm
- selects the unit of measure for object geometries. For
non-pixel unit, the interface created is screen resolution independent and
may be desirable for many applications. Note that for typical screens,
point (about 1/72 inch) and mm may be too coarse and subject
to round-off errors. Use cp (centi-point, 100th of a point) and
cmm (centi-mm) instead.
- selects an alternative format for the generated C code
where global variables are used for the UI components.
- requests the output of main program template.
- requests the output of callback function template.
- requests the emission of font/server resolution variation
- -I headerfile
- uses an alternative header file instead of the default
forms.h in the output C code.
- requests relaxed C syntax checking.
- This option specifies that instead of emitting the c code
for the user interface, PostScript code should be emitted.
- This option requests ada95 code output
- This option requests perl code output.
- This option requests Fortran code output.
- This option requests pascal code output.
- suppresses the output of UI code. Only the .fd file is
The most useful Forms Library
command line options are
- -display host:dpy
- This option specifies the X server to connect.
- This option prints the version string of the Forms
Library, with which fdesign was build.
- -name appname
- This option specifies the application name under which
resources are to be obtained, instead of the executable name.
appname should not contain . or *. fdesign.
The program understands all of the Forms Library
's resource names and
classes as well as the following
- control.geometry (class Control.Geometry)
- specifies the geometry of the control panel. Currently the
size is ignored.
- unit (Unit)
- specifies the default unit of measure. Default is pixel.
- attributes.geometry (class Attributes.Geometry)
- specifies the geometry of the object attributes panel.
Currently the size is ignored.
- align.geometry (class Align.Geometry)
- specifies the geometry of the object align panel. Currently
the size is ignored.
- xformsHeader (class XFormsHeader)
- specifies the header filename generated in the output C
code. Default is forms.h
- filter (class Filter)
- specifies post-processing filter (an external executable
- language (class Language)
- specifies target language name.
Among the standard Forms Library
resources, the following are most useful
- xform.fontsize (class XFORM.FontSize)
- specifies the font size used for most object labels.
- xform.pupfontsize (class XFORM.PupFontSize)
- specifies the font size used in pop-up menus.
- xform.browserFontSize (class XFORM.BrowserFontSize)
- specifies the font size used for the text inside a browser.
