Detailed Description

Function Documentation

generatePreview()

QImage inviwo::utilqt::generatePreview

(

const QString &

classIdentifier

)

Generate an image of a processor including port connections and port names

generateProcessorPreview()

QImage inviwo::utilqt::generateProcessorPreview	(	const QString &	classIdentifier,
		double	opacity = 1.0
	)

Generate an image of a processor

Parameters

classIdentifier	class Identifier of the processor to generate the preview for.
opacity	if opacity is less than one, the output image will be semitransparent, range [0,1]

getApplicationMainWindow()

QMainWindow * inviwo::utilqt::getApplicationMainWindow

(

)

Retrieve the QMainWindow named "InviwoMainWindow" from QApplication.

Returns

The main window if the application contains the widget, otherwise null.

getCurrentStdLocale()

std::locale inviwo::utilqt::getCurrentStdLocale

(

)

getCurrentStdLocale This function returns the current system locale provided by Qt. If the Qt application has not been initialized, the returned value is the environment's default locale.

Returns

std::locale Qt locale converted to std::locale

getMouseButtonCausingEvent()

MouseButton inviwo::utilqt::getMouseButtonCausingEvent

(

const QMouseEvent *

e

)

Convert the button originally causing the event to an inviwo button.

Converts QMouseEvent::getButton().

Note

Qt does not include the button that caused a release event in the regular QMouseEvent::getButtons function, which is why a separate conversion function is necessary

Parameters

e	the QT Mouse Event

Returns

MouseEvent::MouseButton

getMouseButtons()

MouseButtons inviwo::utilqt::getMouseButtons

(

const QMouseEvent *

e

)

Convert the button state when the event was generated to an inviwo button.

Converts QMouseEvent::getButtons().

localizeStream()

std::ios_base & inviwo::utilqt::localizeStream

(

std::ios_base &

stream

)

localize The given stream is imbued with the currently set system locale provided by Qt.

Parameters

stream

the locale is imbued onto this stream

Returns

std::ios_base& reference to the input stream

movePointOntoDesktop()

QPoint inviwo::utilqt::movePointOntoDesktop	(	const QPoint &	point,
		const QSize &	size,
		bool	decorationOffset = true
	)

Moves point to become relative to the main window and thereby visible.

Positions saved for one screen setup may end up outside on other setups. Apply this function to make sure that the widget ends up visible on the screen.

See also

CanvasProcessorWidgetQt

Parameters

point	The previous screen position of the widget
size	The size of the widget
decorationOffset	Offset widget below top horizontal window bar

Returns

The adapted point on the screen, same as input point if no adjustment was necessary

offsetWidget()

QPoint inviwo::utilqt::offsetWidget

(

)

Offset widgets based on order added such that they do not end up on top of each other. Base offset of (350, 100). The offset will be increased by (40, 40) every time the function is called. Furthermore, the horizontal offset will be increased by 200 every tenth time.

Returns
