Member Function Documentation

void StelMainGraphicsView::init

(

)

Start the main initialization of Stellarium.

static StelMainGraphicsView& StelMainGraphicsView::getInstance

(

)

[inline, static]

Get the StelMainGraphicsView singleton instance.

QGLWidget* StelMainGraphicsView::getOpenGLWin

(

)

[inline]

Get the main QGLWidget.

void StelMainGraphicsView::deinitGL

(

)

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

class QProgressBar* StelMainGraphicsView::addProgressBar

(

)

Add a new progress bar in the lower right corner of the screen.

When the progress bar is not used anymore, just delete it.

Returns:

a pointer to the progress bar

void StelMainGraphicsView::activateKeyActions

(

bool

b

)

Activate all the QActions associated to the widget.

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

bool StelMainGraphicsView::getFlagInvertScreenShotColors

(

)

const [inline, slot]

Get whether colors are inverted when saving screenshot.

void StelMainGraphicsView::setFlagInvertScreenShotColors

(

bool

b

)

[inline, slot]

Set whether colors should be inverted when saving screenshot.

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.
