// First time gfxPrefs::GetSingleton() needs to be called on the main thread,
|
|
// before any of the methods accessing the values are used, but after
|
|
// the Preferences system has been initialized.
|
|
|
|
// The static methods to access the preference value are safe to call
|
|
// from any thread after that first call.
|
|
|
|
// To register a preference, you need to add a line in this file using
|
|
// the DECL_GFX_PREF macro.
|
|
//
|
|
// Update argument controls whether we read the preference value and save it
|
|
// or connect with a callback. See UpdatePolicy enum below.
|
|
// Pref is the string with the preference name.
|
|
// Name argument is the name of the static function to create.
|
|
// Type is the type of the preference - bool, int32_t, uint32_t.
|
|
// Default is the default value for the preference.
|
|
//
|
|
// For example this line in the .h:
|
|
// DECL_GFX_PREF(Once,"layers.dump",LayersDump,bool,false);
|
|
// means that you can call
|
|
// bool var = gfxPrefs::LayersDump();
|
|
// from any thread, but that you will only get the preference value of
|
|
// "layers.dump" as it was set at the start of the session (subject to
|
|
// note 2 below). If the value was not set, the default would be false.
|
|
//
|
|
// In another example, this line in the .h:
|
|
// DECL_GFX_PREF(Live,"gl.msaa-level",MSAALevel,uint32_t,2);
|
|
// means that every time you call
|
|
// uint32_t var = gfxPrefs::MSAALevel();
|
|
// from any thread, you will get the most up to date preference value of
|
|
// "gl.msaa-level". If the value is not set, the default would be 2.
|
|
|
|
// Note 1: Changing a preference from Live to Once is now as simple
|
|
// as changing the Update argument. If your code worked before, it will
|
|
// keep working, and behave as if the user never changes the preference.
|
|
// Things are a bit more complicated and perhaps even dangerous when
|
|
// going from Once to Live, or indeed setting a preference to be Live
|
|
// in the first place, so be careful. You need to be ready for the
|
|
// values changing mid execution, and if you're using those preferences
|
|
// in any setup and initialization, you may need to do extra work.
|
|
|
|
// Note 2: Prefs can be set by using the corresponding Set method. For
|
|
// example, if the accessor is Foo() then calling SetFoo(...) will update
|
|
// the preference and also change the return value of subsequent Foo() calls.
|
|
// This is true even for 'Once' prefs which otherwise do not change if the
|
|
// pref is updated after initialization.
