3 | wxSystemOptions stores option/value pairs that wxWidgets itself or | |
4 | applications can use to alter behaviour at run-time. It can be | |
5 | used to optimize behaviour that doesn't deserve a distinct API, | |
6 | but is still important to be able to configure. | |
7 | ||
8 | These options are currently recognised by wxWidgets: | |
9 | ||
10 | \twocolwidtha{7cm} | |
11 | \begin{twocollist}\itemsep=0pt | |
12 | \twocolitem{{\bf Option}}{{\bf Value}} | |
13 | \twocolitem{no-maskblt}{1 to never use WIN32's MaskBlt function, 0 to allow it to be used where possible. Default: 0. | |
14 | ||
15 | In some circumstances the MaskBlt function can be slower than using the fallback code, especially if using | |
16 | DC cacheing. By default, MaskBlt will be used where it is implemented by the operating system and driver. | |
17 | } | |
18 | \twocolitem{mgl.aa-threshold}{(wxMGL only) Set this integer option to point | |
19 | size below which fonts are not antialiased. Default: 10. | |
20 | } | |
21 | \twocolitem{mgl.aa-threshold}{(wxMGL only) Screen refresh rate in Hz. | |
22 | Reasonable default is used if not specified. | |
23 | } | |
24 | \end{twocollist} | |
25 | ||
26 | The compile-time option to include or exclude this functionality | |
27 | is wxUSE\_SYSTEM\_OPTIONS. | |

42 | ||
43 | Default constructor. You don't need to create an instance of wxSystemOptions | |
44 | since all of its functions are static. | |

46 | \membersection{wxSystemOptions::GetOption}\label{wxsystemoptionsgetoption} | |
47 | ||
48 | \constfunc{wxString}{GetOption}{\param{const wxString\&}{ name}} | |
49 | ||
50 | Gets an option. The function is case-insensitive to {\it name}. | |
