Member Function Documentation

autoSwitchMode

void GLWidget::autoSwitchMode ( cher::MOUSE_MODE  mode )

signal

Signal is emitted on double click to automatically switch the mouse mode.

FOVSet

void GLWidget::FOVSet ( double  fov )

signal

Signal is emitted when FOV was changed.

getCamera()

osg::Camera * GLWidget::getCamera

(

)

const

Returns

a non-const pointer on osg::Camera that is current for the GLWidget.

getCameraView()

void GLWidget::getCameraView	(	osg::Vec3d &	eye,
		osg::Vec3d &	center,
		osg::Vec3d &	up,
		double &	fov
	)		const

Method to return manipulator's camera parameters.

getMouseMode()

const cher::MOUSE_MODE GLWidget::getMouseMode

(

)

const

Returns

current mouse mode.

getMousePrevious()

cher::MOUSE_MODE GLWidget::getMousePrevious

(

)

const

Returns

a mouse mode which was before the current one.

getScreenShot()

QPixmap GLWidget::getScreenShot	(	const osg::Vec3d &	eye,
		const osg::Vec3d &	center,
		const osg::Vec3d &	up
	)

Method to obtain a scene graph screenshot by given camera position. This method resets the view back to what it was before the screenshot was taken.

importPhoto

void GLWidget::importPhoto ( const QString &  path, const QString &  fileName  )

signal

Signal is emitted when user performs drag-and-drop from PhotoWidget to GLWidget.

mouseModeSet

void GLWidget::mouseModeSet ( cher::MOUSE_MODE  mode )

signal

Signal is emitted when mouse mode was set. It is connected to MainWindow::onMouseModeSet().

onFOVChangedSlider

void GLWidget::onFOVChangedSlider ( double  fov )

slot

Parameters

fov	is the new FOV (to change manipulator's camera)

onOrthoSet

void GLWidget::onOrthoSet ( bool  ortho )

slot

Parameters

ortho

- true of "ortho" mode is set, false - otherwise.

setCameraView()

void GLWidget::setCameraView	(	const osg::Vec3d &	eye,
		const osg::Vec3d &	center,
		const osg::Vec3d &	up,
		const double &	fov2
	)

Method to set up the manipulator to specified camera paramenters.

Parameters

fov2	is the full angle FOV, in degrees.

setMouseMode()

void GLWidget::setMouseMode

(

const cher::MOUSE_MODE &

mode

)

Parameters

mode	is the mouse mode to set up for the GLWidget and whole application.

setTabletActivity()

void GLWidget::setTabletActivity

(

bool

active

)

Method to set tablet proximity flag.
