Member Function Documentation

◆ initBackend()

void OSystem_iOS7::initBackend ( )

overridevirtual

The following method is called once, from main.cpp, after all config data (including command line params etc.) is fully loaded.

Note: Subclasses should always invoke the implementation of their parent class. They should do so near the end of their own implementation.

Reimplemented from EventsBaseBackend.

◆ engineInit()

void OSystem_iOS7::engineInit ( void )

overridevirtual

Allow the backend to perform engine-specific initialization.

Called just before the engine is run.

Reimplemented from OSystem.

◆ engineDone()

void OSystem_iOS7::engineDone ( )

overridevirtual

Allow the backend to perform engine-specific deinitialization.

Called after the engine finishes.

Reimplemented from OSystem.

◆ taskStarted()

void OSystem_iOS7::taskStarted ( Task )

overridevirtual

Allow the backend to be notified when a task is started.

Reimplemented from OSystem.

◆ taskFinished()

void OSystem_iOS7::taskFinished ( Task )

overridevirtual

Allow the backend to be notified when a task is finished.

Reimplemented from OSystem.

◆ updateStartSettings()

void OSystem_iOS7::updateStartSettings	(	const Common::String &	executable,
		Common::String &	command,
		Common::StringMap &	startSettings,
		Common::StringArray &	additionalArgs
	)

overridevirtual

Allow the backend to customize the start settings, such as for example starting automatically a game under certain circumstances.

This function is called after the command line parameters have been parsed, and thus the initial value of command and settings will reflect those.

The default implementation checks if the executable name is "scummvm-auto" or if a file named "scummvm-autorun" sits next to it to enable autorun mode.

Reimplemented from OSystem.

◆ hasFeature()

bool OSystem_iOS7::hasFeature ( Feature f )

overridevirtual

Determine whether the backend supports the specified feature.

Reimplemented from ModularGraphicsBackend.

◆ setFeatureState()

void OSystem_iOS7::setFeatureState	(	Feature	f,
		bool	enable
	)

overridevirtual

Enable or disable the specified feature.

For example, this may be used to enable fullscreen mode or to deactivate aspect correction, etc.

Reimplemented from ModularGraphicsBackend.

◆ getFeatureState()

bool OSystem_iOS7::getFeatureState ( Feature f )

overridevirtual

Query the state of the specified feature.

For example, test whether fullscreen mode is active or not.

Reimplemented from ModularGraphicsBackend.

◆ setGraphicsMode()

bool OSystem_iOS7::setGraphicsMode	(	int	mode,
		uint	flags
	)

overridevirtual

Switch to the specified graphics mode.

If switching to the new mode fails, this method returns false.

The flag 'kGfxModeRender3d' is optional. It allows to switch to 3D-only rendering mode. In this mode, the game engine is allowed to use OpenGL(ES) directly.

Parameters

mode	ID of the new graphics mode.
flags	Flags for the new graphics mode.

Returns: True if the switch was successful, false otherwise.

Reimplemented from ModularGraphicsBackend.

◆ pollEvent()

bool OSystem_iOS7::pollEvent ( Common::Event & event )

overridevirtual

Query an event from the source.

Parameters

event Reference to the event struct where the event should be stored.

Return values

true	If an event was polled, false otherwise.

Implements Common::EventSource.

◆ getMillis()

uint32 OSystem_iOS7::getMillis ( bool skipRecord = false )

overridevirtual

Get the number of milliseconds since the program was started.

Parameters

skipRecord Skip recording of this value by the event recorder. This might be needed particularly when we are in an on-screen GUI loop where the player can pause the recording.

Implements OSystem.

◆ delayMillis()

void OSystem_iOS7::delayMillis ( uint msecs )

overridevirtual

Delay/sleep for the specified amount of milliseconds.

Implements OSystem.

◆ createMutex()

Common::MutexInternal* OSystem_iOS7::createMutex ( )

overridevirtual

Create a new mutex.

Returns: The newly created mutex, or 0 if an error occurred.

Implements OSystem.

◆ quit()

void OSystem_iOS7::quit ( )

overridevirtual

Quit (exit) the application.

Implements OSystem.

◆ addSysArchivesToSearchSet()

void OSystem_iOS7::addSysArchivesToSearchSet	(	Common::SearchSet &	s,
		int	priority = `0`
	)

overridevirtual

Add system-specific Common::Archive objects to the given SearchSet. For example, on Unix, the directory corresponding to DATA_PATH (if set), or, on macOS, the 'Resource' dir in the app bundle.

Parameters

s	SearchSet to which the system-specific dirs, if any, are added.
priority	Priority with which those dirs are added.

Reimplemented from OSystem.

◆ getTimeAndDate()

void OSystem_iOS7::getTimeAndDate	(	TimeDate &	td,
		bool	skipRecord = `false`
	)		const

overridevirtual

Get the current time and date, in the local timezone.

On many systems, this corresponds to the combination of time() and localtime().

Implements OSystem.

◆ getHardwareInputSet()

Common::HardwareInputSet* OSystem_iOS7::getHardwareInputSet ( )

overridevirtual

Register hardware inputs with keymapper.

Returns: HardwareInputSet with all keys and recommended mappings.

For more information, see keymapper.

Reimplemented from OSystem.

◆ getMixer()

Audio::Mixer* OSystem_iOS7::getMixer ( )

overridevirtual

Return the audio mixer.

For more information, see Audio::Mixer.

Implements OSystem.

◆ getDefaultConfigFileName()

Common::Path OSystem_iOS7::getDefaultConfigFileName ( )

overridevirtual

Get the default file name (or even path) where the user configuration of ScummVM will be saved.

Note that not all ports can use this.

Reimplemented from OSystem.

◆ logMessage()

void OSystem_iOS7::logMessage	(	LogMessageType::Type	type,
		const char *	message
	)

overridevirtual

Log the given message.

It is up to the backend where to log the different messages. The backend should aim at using a non-buffered output for it, so that no log data is lost in case of a crash.

The default implementation outputs them on stdout/stderr.

Parameters

type	Type of the message.
message	The message itself.

Implements OSystem.

◆ fatalError()

void OSystem_iOS7::fatalError ( )

overridevirtual

Signal that a fatal error inside the client code has occurred.

This should quit the application.

Reimplemented from OSystem.

◆ hasTextInClipboard()

bool OSystem_iOS7::hasTextInClipboard ( )

overridevirtual

Check whether there is text available in the clipboard.

The kFeatureClipboardSupport feature flag can be used to test whether this call has been implemented by the active backend.

Returns: True if there is text in the clipboard, false otherwise.

Reimplemented from OSystem.

◆ getTextFromClipboard()

Common::U32String OSystem_iOS7::getTextFromClipboard ( )

overridevirtual

Return clipboard contents as a string.

The kFeatureClipboardSupport feature flag can be used to test whether this call has been implemented by the active backend.

Returns: clipboard contents ("" if hasTextInClipboard() == false).

Reimplemented from OSystem.

◆ setTextInClipboard()

bool OSystem_iOS7::setTextInClipboard ( const Common::U32String & text )

overridevirtual

Set the content of the clipboard to the given string.

The kFeatureClipboardSupport feature flag can be used to test whether this call has been implemented by the active backend.

Returns: True if the text has been properly set in the clipboard, false otherwise.

Reimplemented from OSystem.

◆ openUrl()

bool OSystem_iOS7::openUrl ( const Common::String & url )

overridevirtual

Open the given URL in the default browser (if available on the target system).

Returns: True on success, false otherwise.

Note: It is up to the backend to ensure that the system is in a state that allows the user to actually see the web page. This might for example require leaving fullscreen mode.

Parameters

url	The URL to open.

Reimplemented from OSystem.

◆ buildHelpDialogData()

const char* const* OSystem_iOS7::buildHelpDialogData ( )

overridevirtual

Return list of strings used for building help dialog

The strings represented in triplets:

Name of a tab (will be translated)

		const Common::String &	name,
		const Common::String &	target
	)		const

overridevirtual
