NAME
wxSystemOptions - Functions for wxSystemOptions class
DESCRIPTION
wxSystemOptions stores option/value pairs that wxWidgets itself or
applications can use to alter behaviour at run-time. It can be used to
optimize behaviour that doesn't deserve a distinct API, but is still
important to be able to configure.
System options can be set by the program itself using setOption/2
method and they also can be set from the program environment by defin-
ing an environment variable wx_option to set the given option for all
wxWidgets applications or wx_appname_option to set it just for the
application with the given name (as returned by wxApp::GetAppName()
(not implemented in wx)). Notice that any characters not allowed in the
environment variables names, such as periods and dashes, should be
replaced with underscores. E.g. to define a system option "foo-bar" you
need to define the environment variable "wx_foo_bar".
The program may use system options for its own needs but they are
mostly used to control the behaviour of wxWidgets library itself.
These options are currently recognised by wxWidgets:
All platforms
Windows
GTK+
Mac
Motif
The compile-time option to include or exclude this functionality is
wxUSE_SYSTEM_OPTIONS.

DATA TYPES
wxSystemOptions() = wx:wx_object()
EXPORTS
getOption(Name) -> unicode:charlist()
Types:
Name = unicode:chardata()
Gets an option.
The function is case-insensitive to name. Returns empty string
if the option hasn't been set.
See: setOption/2, getOptionInt/1, hasOption/1
getOptionInt(Name) -> integer()
Types:
Name = unicode:chardata()
Gets an option as an integer.
The function is case-insensitive to name. If the option hasn't
been set, this function returns 0.
See: setOption/2, getOption/1, hasOption/1
hasOption(Name) -> boolean()
Types:
Name = unicode:chardata()
Returns true if the given option is present.
The function is case-insensitive to name.
See: setOption/2, getOption/1, getOptionInt/1
isFalse(Name) -> boolean()
Types:
Name = unicode:chardata()
Returns true if the option with the given name had been set to 0
value.
This is mostly useful for boolean options for which you can't
use GetOptionInt(name) == 0 as this would also be true if the
option hadn't been set at all.
setOption(Name, Value) -> ok
setOption(Name, Value) -> ok
Types:
Name = Value = unicode:chardata()
Sets an option.
The function is case-insensitive to name.
