Detailed Description

Module for managing images for scripting.

Images are identified by a string ID which is passed to ScreenImageMgr members when it is necessary to specify an image to work with. Member functions in this class which modify the state of the class are all mediated through the signal/slot mechanism to ensure such operations happen in the main thread where images are drawn, and not in the script thread.

Definition at line 103 of file ScreenImageMgr.hpp.

Constructor & Destructor Documentation

ScreenImageMgr::ScreenImageMgr

(

)

Construct a LabelMgr object.

Member Function Documentation

void ScreenImageMgr::createScreenImage ( const QString &  id, const QString &  filename, float  x, float  y, float  scale = 1., bool  visible = true, float  alpha = 1., float  fadeDuration = 1.  )

slot

Create an image from a file and display on the screen at x,y coordinates.

Parameters

id	the ID to use when referring to this image (an arbitrary string).
filename	the partial path of the file to load. This will be searched for using StelFileMgr, with "scripts/" prefixed to the filename.
x	The x-coordinate for the image (0 = left of screen)
y	The y-coordinate for the image (0 = bottom of screen)
scale	Image scale multiplier.
visible	The initial visible state of the image
alpha	The initial alpha (transparancy) value for the image (range 0.0 to 1.0)
fadeDuration	the time it takes for screen images to fade in/out/change alpha in seconds.

void ScreenImageMgr::deleteAllImages ( void  )

slot

Delete all images currently managed by ScreenImageMgr.

void ScreenImageMgr::deleteImage ( const QString &  id )

slot

Delete an image.

Parameters

id	the ID for the desired image.

virtual void ScreenImageMgr::draw ( StelCore *  core, class StelRenderer *  renderer  )

virtual

Execute all the drawing functions for this module.

Parameters

core	the core to use for the drawing
renderer	Renderer to draw with.

Reimplemented from StelModule.

QStringList ScreenImageMgr::getAllImageIDs ( void  )

slot

Get a list of currently loaded image I
