16 : // First time gfxPrefs::GetSingleton() needs to be called on the main thread,
17 : // before any of the methods accessing the values are used, but after
18 : // the Preferences system has been initialized.
19 :
20 : // The static methods to access the preference value are safe to call
21 : // from any thread after that first call.
22 :
23 : // To register a preference, you need to add a line in this file using
24 : // the DECL_GFX_PREF macro.
25 : //
26 : // Update argument controls whether we read the preference value and save it
27 : // or connect with a callback. See UpdatePolicy enum below.
28 : // Pref is the string with the preference name.
29 : // Name argument is the name of the static function to create.
30 : // Type is the type of the preference - bool, int32_t, uint32_t.
31 : // Default is the default value for the preference.
32 : //
33 : // For example this line in the .h:
34 : // DECL_GFX_PREF(Once,"layers.dump",LayersDump,bool,false);
35 : // means that you can call
36 : // bool var = gfxPrefs::LayersDump();
37 : // from any thread, but that you will only get the preference value of
38 : // "layers.dump" as it was set at the start of the session (subject to
39 : // note 2 below). If the value was not set, the default would be false.
40 : //
41 : // In another example, this line in the .h:
42 : // DECL_GFX_PREF(Live,"gl.msaa-level",MSAALevel,uint32_t,2);
43 : // means that every time you call
44 : // uint32_t var = gfxPrefs::MSAALevel();
45 : // from any thread, you will get the most up to date preference value of
46 : // "gl.msaa-level". If the value is not set, the default would be 2.
47 :
48 : // Note 1: Changing a preference from Live to Once is now as simple
49 : // as changing the Update argument. If your code worked before, it will
50 : // keep working, and behave as if the user never changes the preference.
51 : // Things are a bit more complicated and perhaps even dangerous when
52 : // going from Once to Live, or indeed setting a preference to be Live
53 : // in the first place, so be careful. You need to be ready for the
54 : // values changing mid execution, and if you're using those preferences
55 : // in any setup and initialization, you may need to do extra work.
56 :
57 : // Note 2: Prefs can be set by using the corresponding Set method. For
58 : // example, if the accessor is Foo() then calling SetFoo(...) will update
59 : // the preference and also change the return value of subsequent Foo() calls.
60 : // This is true even for 'Once' prefs which otherwise do not change if the
61 : // pref is updated after initialization. Changing gfxPrefs values in content
62 : // processes will not affect the result in other processes. Changing gfxPrefs
63 : // values in the GPU process is not supported at all.
