Wx::SystemOptions

SystemOptions stores option/value pairs that Widgets 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.

These options are currently recognised by Widgets.

Windows

Option Value
no-maskblt 1 to never use WIN32’s MaskBlt function, 0 to allow it to be used where possible. Default: 0.In some circumstances the MaskBlt function can be slower than using the fallback code, especially if usingDC cacheing. By default, MaskBlt will be used where it is implemented by the operating system and driver.
msw.remap If 1 (the default), ToolBar bitmap colours will be remappedto the current theme’s values. Set this to 0 to disable this functionality, for example if you’re usingmore than 16 colours in your tool bitmaps.
msw.window.no-clip-children If 1, windows will not automatically get the WS_CLIPCHILDRENstyle. This restores the way windows are refreshed back to the method used in versions of Widgetsearlier than 2.5.4, and for some complex window hierarchies it can reduce apparent refresh delays. You maystill specify CLIP_CHILDREN for individual windows.
msw.notebook.themed-background If set to 0, globally disables themed backgrounds on notebookpages. Note that this won’t disable the theme on the actual notebook background (noticeable only if there are nopages).
msw.staticbox.optimized-paint If set to 0, switches off optimized StaticBox painting.Setting this to 0 causes more flicker, but allows applications to paint graphics on the parent of a static box(the optimized refresh causes any such drawing to disappear).

Mac

Option Value
mac.window-plain-transition If 1, uses a plainer transition when showinga window. You can also use the symbol MAC_WINDOW_PLAIN_TRANSITION.
window-default-variant The default variant used by windows (cast to integer from the WindowVariant enum).Also known as WINDOW_DEFAULT_VARIANT.

MGL

Option Value
mgl.aa-threshold Set this integer option to pointsize below which fonts are not antialiased. Default: 10.
mgl.screen-refresh Screen refresh rate in Hz.A reasonable default is used if not specified.

Motif

Option Value
motif.largebuttons If 1, uses a bigger default size for Buttons.

The compile-time option to include or exclude this functionality
is USE_SYSTEM_OPTIONS.

Methods

SystemOptions.new

SystemOptions#get_option

String get_option(%(arg-type)String% name)

Gets an option. The function is case-insensitive to name.

Returns empty string if the option hasn’t been set.

SystemOptions#set_option, SystemOptions#get_option_int, SystemOptions#has_option

SystemOptions#get_option_int

Integer get_option_int(%(arg-type)String% name)

Gets an option as an integer. The function is case-insensitive to name.

If the option hasn’t been set, this function returns $0$.

SystemOptions#set_option, SystemOptions#get_option, SystemOptions#has_option

SystemOptions#has_option

Boolean has_option(%(arg-type)String% name)

Returns if the given option is present. The function is case-insensitive to name.

See also

SystemOptions#set_option, SystemOptions#get_option, SystemOptions#get_option_int

SystemOptions#is_false

Boolean is_false(%(arg-type)String% name)

Returns 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.

SystemOptions#set_option

set_option(%(arg-type)String% name, String value) set_option(%(arg-type)String% name, Integer value)

Sets an option. The function is case-insensitive to name.
