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: + + @section sysopt_all All platforms + + @beginFlagTable + @flag{exit-on-assert} + If set to non-zero value, abort the program if an assertion fails. The + default behaviour in case of assertion failure depends on the build mode + and can be changed by overriding wxApp::OnAssertFailure() but setting + this option allows to change it without modifying the program code and + also applies to asserts which may happen before the wxApp object + creation or after its destruction. + @endFlagTable + + @section sysopt_win Windows + + @beginFlagTable + @flag{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 using DC caching. By default, MaskBlt will be + used where it is implemented by the operating system and driver. + @flag{msw.remap} + If 1 (the default), wxToolBar bitmap colours will be remapped to the current + theme's values. Set this to 0 to disable this functionality, for example if + you're using more than 16 colours in your tool bitmaps. + @flag{msw.window.no-clip-children} + If 1, windows will not automatically get the WS_CLIPCHILDREN style. + This restores the way windows are refreshed back to the method used in + versions of wxWidgets earlier than 2.5.4, and for some complex window + hierarchies it can reduce apparent refresh delays. + You may still specify wxCLIP_CHILDREN for individual windows. + @flag{msw.notebook.themed-background} + If set to 0, globally disables themed backgrounds on notebook pages. + Note that this won't disable the theme on the actual notebook background + (noticeable only if there are no pages). + @flag{msw.staticbox.optimized-paint} + If set to 0, switches off optimized wxStaticBox 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). + @flag{msw.display.directdraw} + If set to 1, use DirectDraw-based implementation of wxDisplay. + By default the standard Win32 functions are used. + @flag{msw.font.no-proof-quality} + If set to 1, use default fonts quality instead of proof quality when + creating fonts. With proof quality the fonts have slightly better + appearance but not all fonts are available in this quality, + e.g. the Terminal font in small sizes is not and this option may be + used if wider fonts selection is more important than higher quality. + @flag{wince.dialog.real-ok-cancel} + The PocketPC guidelines recommend for Ok/Cancel dialogs to use an OK button + located inside the caption bar and implement Cancel functionality through + Undo outside the dialog. + wxDialog::CreateButtonSizer will follow the native behaviour on WinCE but + it can be overridden with real wxButtons by setting the option below to 1. + @endFlagTable + + + @section sysopt_gtk GTK+ + + @beginFlagTable + @flag{gtk.tlw.can-set-transparent} + wxTopLevelWindow::CanSetTransparent() method normally tries to detect + automatically whether transparency for top level windows is currently + supported, however this may sometimes fail and this option allows to + override the automatic detection. Setting it to 1 makes the transparency + be always available (setting it can still fail, of course) and setting it + to 0 makes it always unavailable. + @flag{gtk.desktop} + This option can be set to override the default desktop environment + determination. Supported values are GNOME and KDE. + @flag{gtk.window.force-background-colour} + If 1, the backgrounds of windows with the wxBG_STYLE_COLOUR background + style are cleared forcibly instead of relying on the underlying GTK+ + window colour. This works around a display problem when running + applications under KDE with the gtk-qt theme installed (0.6 and below). + @endFlagTable + + + @section sysopt_mac Mac + + @beginFlagTable + @flag{mac.window-plain-transition} + If 1, uses a plainer transition when showing a window. + You can also use the symbol wxMAC_WINDOW_PLAIN_TRANSITION. + @flag{window-default-variant} + The default variant used by windows (cast to integer from the wxWindowVariant enum). + Also known as wxWINDOW_DEFAULT_VARIANT. + @flag{mac.listctrl.always_use_generic} + Tells wxListCtrl to use the generic control even when it is capable of + using the native control instead. Also known as wxMAC_ALWAYS_USE_GENERIC_LISTCTRL. + @flag{mac.textcontrol-use-spell-checker} + This option only has effect for Mac OS X 10.4 and higher. + If 1 activates the spell checking in wxTextCtrl. + @flag{osx.openfiledialog.always-show-types} + Per default a wxFileDialog with wxFD_OPEN does not show a types-popup on OSX but allows + the selection of files from any of the supported types. Setting this to 1 shows a wxChoice + for selection (if there is more than one supported filetype). + @endFlagTable + + + @section sysopt_mgl MGL + + @beginFlagTable + @flag{mgl.aa-threshold} + Set this integer option to point size below which fonts are not antialiased.
