Member Function Documentation

void CXWindowsScreen::checkClipboards ( ) [virtual]

Check clipboard owner.

Check ownership of all clipboards and post grab events for any that have changed. This is used as a backup in case the system doesn't reliably report clipboard ownership changes.

Implements CPlatformScreen.

Definition at line 405 of file CXWindowsScreen.cpp.

void CXWindowsScreen::closeScreensaver ( ) [virtual]

Close screen saver.

Close the screen saver. Stop reporting screen saver activation and deactivation and, if the screen saver was disabled by openScreensaver(), enable the screen saver.

Implements CPlatformScreen.

Definition at line 420 of file CXWindowsScreen.cpp.

References CXWindowsScreenSaver::enable().

void CXWindowsScreen::disable ( ) [virtual]

Disable screen.

Undoes the operations in enable() and events should no longer be reported.

Implements CPlatformScreen.

Definition at line 244 of file CXWindowsScreen.cpp.

void CXWindowsScreen::enable ( ) [virtual]

Enable screen.

Enable the screen, preparing it to report system and user events. For a secondary screen it also means preparing to synthesize events and hiding the cursor.

Implements CPlatformScreen.

Definition at line 222 of file CXWindowsScreen.cpp.

References CXWindowsKeyState::setAutoRepeat().

void CXWindowsScreen::enter ( ) [virtual]

Enter screen.

Called when the user navigates to this screen.

Implements CPlatformScreen.

Definition at line 262 of file CXWindowsScreen.cpp.

References screensaver(), and CXWindowsKeyState::setAutoRepeat().

IKeyState * CXWindowsScreen::getKeyState ( ) const [protected, virtual]

Get the key state.

Subclasses must implement this method to return the platform specific key state object that each subclass must have.

Implements CPlatformScreen.

Definition at line 1155 of file CXWindowsScreen.cpp.

void CXWindowsScreen::handleSystemEvent	(	const CEvent &	event,
		void *
	)			`[protected, virtual]`

Handle system event.

A platform screen is expected to install a handler for system events in its c'tor like so:

    EVENTQUEUE->adoptHandler(CEvent::kSystem,
                         IEventQueue::getSystemTarget(),
                         new TMethodEventJob<CXXXPlatformScreen>(this,
                             &CXXXPlatformScreen::handleSystemEvent));

It should remove the handler in its d'tor. Override the handleSystemEvent() method to process system events. It should post the events IScreen as appropriate.

A primary screen has further responsibilities. It should post the events in IPrimaryScreen as appropriate. It should also call onKey() on its CKeyState whenever a key is pressed or released (but not for key repeats). And it should call updateKeyMap() on its CKeyState if necessary when the keyboard mapping changes.

The target of all events should be the value returned by getEventTarget().

References CXWindowsClipboard::addRequest(), IScreen::getClipboardGrabbedEvent(), CXWindowsScreenSaver::handleXEvent(), CXWindowsClipboard::lost(), CXWindowsKeyState::mapModifiersFromX(), CKeyState::onKey(), and CXWindowsKeyState::setActiveGroup().

bool CXWindowsScreen::isPrimary ( ) const [virtual]

Test if is primary screen.

Return true iff this screen is a primary screen.

Implements CPlatformScreen.

Definition at line 467 of file CXWindowsScreen.cpp.

bool CXWindowsScreen::leave ( ) [virtual]

Leave screen.

Called when the user navigates off the screen. Returns true on success, false on failure. A typical reason for failure is being unable to install the keyboard and mouse snoopers on a primary screen. Secondary screens should not fail.

Implements CPlatformScreen.

Definition at line 321 of file CXWindowsScreen.cpp.

void CXWindowsScreen::openScreensaver ( bool notify ) [virtual]

Open screen saver.

Open the screen saver. If notify is true then this object must send events when the screen saver activates or deactivates until closeScreensaver() is called. If notify is false then the screen saver is disabled and restored on closeScreensaver().

Implements CPlatformScreen.

Definition at line 411 of file CXWindowsScreen.cpp.

References CXWindowsScreenSaver::disable().

void CXWindowsScreen::resetOptions ( ) [virtual]

Notify of options changes.

Reset all options to their default values.

Implements CPlatformScreen.

Definition at line 439 of file CXWindowsScreen.cpp.

void CXWindowsScreen::screensaver ( bool activate ) [virtual]

Activate/deactivate screen saver.

Forcibly activate the screen saver if activate is true otherwise forcibly deactivate it.

Implements CPlatformScreen.
