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.

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.

GSAppOwnsMiniwindow is for miniwindows (not app icons). If it's YES or absent, GNUstep handles miniaturization itself and doesn't let the window manager do it. If it's NO, the window manager is allowed to do its own iconification. This does not affect app icons at all.

With the xlib backend, this is a boolean value which defaults to NO. If set to YES and X Windows system has the XFT extension, then the application will use anti-aliased fonts as provided by XFT..

With the art backend, A boolean value which defaults to YES. If YES, text is anti-aliased at small sizes (9-16 pixels). The value is advisory (specific fonts can override this setting).

[Xlib backend only] A string value which defaults to "*". It defines the pattern used to get the installed fonts from the X-Server. A value of "*-iso8859-1" would only include fonts available with ISO Western encoding. This feature might be helpfull if the font_cacher program is having problem with the X-Server.

A string value used to specify the XIM input method for entering characters. Valid values are RootWindow, OffTheSpot, or OverTheSpot.

[Xlib backend only] A boolean value which defaults to YES. If set to YES, 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.

The OPENstep specification requires 3 main different keyboard modifiers: CONTROL, COMMAND and ALTERNATE. Some systems may not have these set up correctly. You can changed the defaults with the default keys.

Default values are respectively:

This is described more completely in the GUI documentation.

UseWindowMakerIcons is for app icons, and has no effect when the window manager isn't Window Maker. It displays the application's icon window in the window Window Maker provides instead of creating one controlled by the app. This allows the icon to be docked. It is a boolean value which defaults to YES.

A boolean value which defaults to YES (as long as shared memory is available). If set to NO, shared memory is not used for various display specific operations.
