This document contains a summary of available user default
|

|
|
values that one can set to control the operation of the GNUstep

libraries.

Below is a list of defaults used to control the gnustep-gui library.

|
|
<term>GSBackend</term>
|
||
|
|
<desc>
|
||
|
|
<p>
|
||
|
|
A string containing the name of the backend bundle to use
|
||
|
|
for display specific GUI handling. The default is
|
||
|
|
"libgnustep-xgps.bundle". Currently the only other choice is
|
||
|
|
"libgnustep-xdps.bundle".

<term>GSBrowserCellFontify</term>
|
||
|
|
<desc>
|
||
|
|
<p>
|
||
|
|
A boolean value, <code>NO</code> by default. When the feature is on,
|
||
|
|
NSBrowserCell draws non-leaf cells in bold system font.
|
||
|
|
For example, when the feature is on, in a SavePanel (or OpenPanel),
|
||
|
|
directory entries are drawn in bold, while simple files are drawn in
|
||
|
|
non bold.
|
||

|
<term>GSSavePanelShowProgress</term>
|
||
|
|
<desc>
|
||
|
|
<p>
|
||
|
|
A boolean value, <code>NO</code> by default. When the
|
||
|
|
feature is on, the save panel and its subclasses (such as
|
||
|
|
the open panel) displays "Reading Directory ***.."
|
||
|
|
(progressively adding dots) in the window titlebar while
|
||
|
|
reading very big directories (more than 100 entries). This
|
||
|
|
is meant to make things friendlier for slow computers. Not
|
||
|
|
well tested.

<term>GSLogWorkspaceTimeout</term>
|
||
|
|
<desc>
|
||
|
|
<p>
|
||
|
|
A boolean value that defaults to <code>NO</code>. This is a
|
||
|
|
obscure and probably not useful default. NSWorkspace tries
|
||
|
|
to receive distributed notifications, but if a distributed
|
||
|
|
objects server cannot be found or some other error occurs,
|
||
|
|
it raises an exception which normally terminates the
|
||
|
|
program. Setting this default causes NSWorkspace to just log
|
||
|
|
the problem without raising an exception.

<term>NSInterfaceStyleDefault</term>
|
||
|
|
<desc>
|
||
|
|
<p>
|
||
|
|
A string describing the interface style. Setting this may
|
||
|
|
change various aspects of how the library draws elements and
|
||
|
|
responds to user interaction. See the NSInterfaceStyle
|
||
|
|
documentation for more information.

<term>NSMenuInterfaceStyle</term>
|
||
|
|
<desc>
|
||
|
|
<p>
|
||
|
|
An interface style specific to menu operation. If not set
|
||
|
|
the NSInterfaceStyleDefault value is used.

|
<term>NSCommandKeys</term>
|
||
|
|
<desc>
|
||
|
|
<p>
|
||
|
|
A dictionary of command key equivalents for menu items. The
|
||
|
|
key contains the title of the menu item and the value is the
|
||
|
|
command key equivalent. For instance, one might set the
|
||
|
|
command key for the menu item "Copy" to "C".

<term>NSHost</term>
|

|

<p>

Used by NSPasteboard to find the host on which the

|
|
pasteboard server is running.

<term>NSMeasurementUnit</term>
|

|
||
|
|
<p>
|
||
|
|
A string describing the measurement unit for rulers (see the
|
||
|
|
NSRulerView class documentation). The default is
|
||
|
|
Centimeters. Other possible values are Inches, Points, and Picas.

<term><em>System Colors</em></term>
|

|

|
|
<p>
|
||
|
|
System colors may be set using the defaults system. System
|
||
|
|
colors are standard colors for drawing various GUI elements,
|
||
|
|
such as buttons, text, scroller, etc. The value is a
|
||
|
|
dictionary describing the color. The keys that can be
|
||
|
|
used for setting the system colors are described in the
|
||
|
|
documentation for NSColor.

|

<p>
|
||
|
|
System Fonts may be set using the defaults system. System
|
||
|
|
fonts are standard fonts for drawing text in GUI
|
||
|
|
elements. They include NSBoldFont, for instance. The value
|
||
|
|
is the name of the font to use. There is also a
|
||
|
|
cooresponding size key (e.g. NSBoldFontSize) for specifying
|
||
|
|
the point size of the font. The keys that can be used for
|
||
|
|
setting the system fonts are described in the documentation
|
||
|
|
for NSFont.

<heading>XGPS Backend Defaults</heading>
|
||
|
|
<p>
|
||
|
|
Below is a list of defaults used to control the gnustep-xgps
|
||
|
|
backend. These defaults generally control system specific
|
||
|
|
display and user interaction options which may not be available
|
||
|
|
on all systems.

|
<term>NSDefaultVisual</term>
|
||
|
|
<desc>
|
||
|
|
<p>
|
||
|
|
An integer that specifies the X-Windows visual class to use
|
||
|
|
in the application. For instance one could display the
|
||
|
|
application using the PsuedoColor visual class by setting
|
||
|
|
the value to the id of this class. The default is the
|
||
|
|
X-Windows default visual class.

|
|
<term>NSColorsPerChannel</term>
|
||
|
|
<desc>
|
||
|
|
<p>
|
||
|
|
An integer which limits the maximum number of colors to
|
||
|
|
display, per channel. For a psuedo-color display, this would
|
||
|
|
limit the total number of colors that the application could
|
||
|
|
use (normally 256). For a true-color display, this would
|
||
|
|
limit the range of red, green, and blue values that could be used.

<term>XGPS-Shm</term>
|
||
|

<desc>
|
||
|
|
<p>
|
||
|
|
A boolean value which defaults to <code>YES</code> (as long as shared
|
||
|
|
memory is available). If set to <code>NO</code>, shared memory is not
|
||
|
|
used for various display specific operations.

<term>GSFontAntiAlias</term>
|
||
|
|
<desc>
|
||
|
|
<p>
|
||
|
|
A boolean value which defaults to <code>NO</code>. If set to
|
||
|
|
<code>YES</code> and the X-Windows system has the XFT
|
||
|
|
extension, then the application will use anti-aliased fonts
|
||
|
|
as provided by the X-Windows system.

<term>GraphicCompositing</term>
|

|
||
|
|
<p>
|
||
|
|
A boolean value which defaults to <code>NO</code>. If set to
|
||
|
|
<code>YES</code>, then the application uses various tricks
|
||
|
|
to get alpha colors to work when compositing images. This
|
||
|
|
may slow down drawing of images, but it is generally
|
||
|
|
recommended anyway, particularly on fast systems.
