Member Function Documentation

void StelMainGraphicsView::deinitGL

(

)

Delete openGL textures (to call before the GLContext disappears).

virtual void StelMainGraphicsView::drawBackground	(	QPainter *	painter,
		const QRectF &	rect
	)			[protected, virtual]

Update the mouse pointer state and schedule next redraw.

This method is called automatically by Qt.

float StelMainGraphicsView::getCursorTimeout

(

)

const [inline, slot]

Get the mouse cursor timeout in seconds.

bool StelMainGraphicsView::getFlagCursorTimeout

(

)

[inline, slot]

Get the state of the mouse cursor timeout flag.

bool StelMainGraphicsView::getFlagInvertScreenShotColors

(

)

const [inline, slot]

Get whether colors are inverted when saving screenshot.

static StelMainGraphicsView& StelMainGraphicsView::getInstance

(

)

[inline, static]

Get the StelMainGraphicsView singleton instance.

StelMainScriptAPIProxy* StelMainGraphicsView::getMainScriptAPIProxy

(

)

[inline]

Get the script API proxy (for signal handling).

float StelMainGraphicsView::getMaxFps

(

)

[inline, slot]

Get the current maximum frames per second.

float StelMainGraphicsView::getMinFps

(

)

[inline, slot]

Get the current minimum frames per second.

StelScriptMgr& StelMainGraphicsView::getScriptMgr

(

)

[inline]

Get the script manager.

class StelAppGraphicsWidget* StelMainGraphicsView::getStelAppGraphicsWidget

(

)

[inline]

Return the QGraphicsWidget encapsulating the Stellarium main sky view.

Use its layout if you want to add widget on the top of the main sky view.

QGraphicsWidget* StelMainGraphicsView::getTopLevelGraphicsWidget

(

)

[inline]

Return the top level QGraphicsWidget which contains the layout containing the Stellarium main sky view.

Use its layout if you want to add widget on the side of the main sky view.

void StelMainGraphicsView::init

(

class QSettings *

conf

)

Start the main initialization of Stellarium.

void StelMainGraphicsView::saveScreenShot	(	const QString &	filePrefix = "stellarium-",
		const QString &	saveDir = ""
	)			[slot]

Save a screen shot.

The format of the file, and hence the filename extension depends on the architecture and build type.

• filePrefix changes the beginning of the file name
• shotDir changes the directory where the screenshot is saved If shotDir is "" then StelFileMgr::getScreenshotDir() will be used

void StelMainGraphicsView::screenshotRequested

(

void

)

[signal]

emitted when saveScreenShot is requested with saveScreenShot().

doScreenshot() does the actual work (it has to do it in the main thread, where as saveScreenShot() might get called from another one.

void StelMainGraphicsView::setCursorTimeout

(

float

t

)

[inline, slot]

Set the mouse cursor timeout in seconds.

void StelMainGraphicsView::setFlagCursorTimeout

(

bool

b

)

[inline, slot]

Get the state of the mouse cursor timeout flag.

void StelMainGraphicsView::setFlagInvertScreenShotColors

(

bool

b

)

[inline, slot]

Set whether colors should be inverted when saving screenshot.

void StelMainGraphicsView::setMaxFps

(

float

m

)

[inline, slot]

Set the maximum frames per second.

Parameters:

m

the new maximum fps setting.

void StelMainGraphicsView::setMinFps

(

float

m

)

[inline, slot]

Set the minimum frames per second.

Usually this minimum will be switched to after there are no user events for some seconds to save power. However, if can be useful to set this to a high value to improve playing smoothness in scripts.

Parameters:

m

the new minimum fps setting.

void StelMainGraphicsView::updateScene

(

)

[inline, slot]

Updates the scene and process all events.
