.SH NAME
wxSystemOptions \- 
  System options class for run-time configuration
 
.SH 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.
  
  


   These options are currently recognised by wxWidgets.
  
  


   
    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 using DC cacheing. By default, MaskBlt will be used where it is implemented by the operating system and driver.
     
    

     
    
     
      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.
     
    

     
    
     
      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.
     
    

     
    
     
      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).
     
    

     
    
     
      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).
     
    

   
  
  


   
    Mac
   
  
  


   
    
     
      
       Option
      
     
     
      
       Value
      
     
    

     
    
     
      mac.window-plain-transition
     
     
      If 1, uses a plainer transition when showing a window. You can also use the symbol wxMAC_WINDOW_PLAIN_TRANSITION.
     
    

     
    
     
      window-default-variant
     
     
      The default variant used by windows (cast to integer from the wxWindowVariant enum). Also known as wxWINDOW_DEFAULT_VARIANT.
     
    

   
  
  


   
    MGL
   
  
  


   
    
     
      
       Option
      
     
     
      
       Value
      
     
    

     
    
     
      mgl.aa-threshold
     
     
      Set this integer option to point size 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 wxButtons.
     
    

   
  
  


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

.SS  wxSystemOptions ()

     


      Default constructor. You don't need to create an instance of
      wxSystemOptions since all of its functions are static.
     
    
   
  
.SS wxString GetOption (const wxString& name)

     


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


      Returns empty string if the option hasn't been set.
     
    
   
  
.SS int GetOptionInt (const wxString& 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.
     
    
   
  
.SS bool HasOption (const wxString& name)

     


      Returns true if the given option is present. The function is
      case-insensitive to
      
       name
      
      .
     
    
   
  
.SS bool IsFalse (const wxString& name)

     


      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.
     
    
   
  
.SS void SetOption (const wxString& nameconst wxString& value)

.SS void SetOption (const wxString& nameint value)

     


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