Detailed Description

Specialization for connecting with Qt.

Set a QBasicTimer on this or call startTimer() to update all associated windows using Root::renderOneFrame.
Use the QWindow::requestUpdate() slot to refresh a single Window using RenderWindow::update
QWidget::createWindowContainer and QWidget::windowHandle() provide translation between QWidget and QWindow

Assumes that Ogre Main loop is used for compatibility with other implementations.

Member Function Documentation

◆ createWindow() [1/2]

NativeWindowPair OgreBites::ApplicationContextQt::createWindow	(	const Ogre::String &	name,
		uint32_t	w = `0`,
		uint32_t	h = `0`,
		Ogre::NameValuePairList	miscParams = `Ogre::NameValuePairList()`
	)

overridevirtual

Create a new render window.

You must use SDL and not an auto-created window as SDL does not get the events otherwise.

By default the values from ogre.cfg are used for w, h and miscParams.

Reimplemented from OgreBites::ApplicationContextBase.

◆ createWindow() [2/2]

NativeWindowPair OgreBites::ApplicationContextQt::createWindow	(	QWindow *	window,
		Ogre::NameValuePairList	miscParams = `Ogre::NameValuePairList()`
	)

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

◆ injectMainWindow()

void OgreBites::ApplicationContextQt::injectMainWindow ( QWindow * window )

inline

allows overriding the main (first) Window with a pre-created QWindow

Parameters

window

References OgreAssert.

◆ useQtEventLoop()

void OgreBites::ApplicationContextQt::useQtEventLoop ( bool enable )

inline

signal that you want to use the Qt event loop

aka QApplication::exec() instead of Root::startRendering. In this case you may want to call startTimer on this QObject which ensures that Root::renderOneFrame is called periodically.

Parameters

enable

◆ setWindowGrab() [1/3]

void OgreBites::ApplicationContextQt::setWindowGrab	(	NativeWindowType *	win,
		bool	grab
	)

overridevirtual

When input is grabbed the mouse is confined to the window.

Reimplemented from OgreBites::ApplicationContextBase.

◆ addInputListener() [1/3]

void OgreBites::ApplicationContextQt::addInputListener	(	NativeWindowType *	win,
		InputListener *	lis
	)

overridevirtual

attach input listener

Parameters

lis	the listener
win	the window to receive the events for.

Reimplemented from OgreBites::ApplicationContextBase.

◆ removeInputListener() [1/3]

void OgreBites::ApplicationContextQt::removeInputListener	(	NativeWindowType *	win,
		InputListener *	lis
	)

overridevirtual

detatch input listener

Parameters

lis	the listener
win	the window to receive the events for.

Reimplemented from OgreBites::ApplicationContextBase.

◆ pollEvents()

void OgreBites::ApplicationContextQt::pollEvents ( )

overridevirtual

process all window events since last call

Reimplemented from OgreBites::ApplicationContextBase.

◆ shutdown()

void OgreBites::ApplicationContextQt::shutdown ( )

overridevirtual

Cleans up and shuts down the context.

Reimplemented from OgreBites::ApplicationContextBase.

◆ setWindowGrab() [2/3]

virtual void OgreBites::ApplicationContextBase::setWindowGrab

inline

When input is grabbed the mouse is confined to the window.

◆ setWindowGrab() [3/3]

void OgreBites::ApplicationContextBase::setWindowGrab

inline

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

◆ addInputListener() [2/3]

virtual void OgreBites::ApplicationContextBase::addInputListener

attach input listener

Parameters

lis	the listener
win	the window to receive the events for.

◆ addInputListener() [3/3]

void OgreBites::ApplicationContextBase::addInputListener

inline

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.

◆ removeInputListener() [2/3]

virtual void OgreBites::ApplicationContextBase::removeInputListener

detatch input listener

Parameters

lis	the listener
win	the window to receive the events for.

◆ removeInputListener() [3/3]

void OgreBites::ApplicationContextBase::removeInputListener

inline

This is an overloaded member function, provided for convenience. It differs from the above function only in what argument(s) it accepts.
