Detailed Description

This is the common base class for all the main components of stellarium.

Standard StelModules are the one displaying the stars, the constellations, the planets etc.. Every new module derived class should implement the methods defined in StelModule.hpp. Once a module is registered into the StelModuleMgr, it is automatically managed by the program. It can be called using the GETSTELMODULE macro, passing as argument its name, which is also the QObject name Because StelModules are very generic components, it is also possible to load them dynamically, thus enabling creation of external plug-ins for stellarium.

See also:
StelObjectModule for StelModule managing collections of StelObject.
Plugins for documentation on how to develop external plugins.

There are several signals that StelApp emits that subclasses may be interested in: laguageChanged() Update i18n strings from english names according to current global sky and application language. This method also reload the proper fonts depending on the language. The translation shall be done using the StelTranslator provided by the StelApp singleton instance. skyCultureChanged(const QString&) Update sky culture, i.e. load data if necessary and translate them to current sky language if needed. colorSchemeChanged(const QString&) Load the given color style


Member Enumeration Documentation

Define the possible action for which an order is defined.

Enumerator:
ActionDraw 

Action associated to the draw() method.

ActionUpdate 

Action associated to the update() method.

ActionHandleMouseClicks 

Action associated to the handleMouseClicks() method.

ActionHandleMouseMoves 

Action associated to the handleMouseMoves() method.

ActionHandleKeys 

Action associated to the handleKeys() method.

Enum used when selecting objects to define whether to add to, replace, or remove from the existing selection list.

Enumerator:
AddToSelection 

Add the StelObject to the current list of selected ones.

ReplaceSelection 

Set the StelObject as the new list of selected ones.

RemoveFromSelection 

Subtract the StelObject from the current list of selected ones.


Member Function Documentation

virtual bool StelModule::configureGui ( bool  show = true) [inline, virtual]

Detect or show the configuration GUI elements for the module.

This is to be used with plugins to display a configuration dialog from the plugin list window.

Parameters:
showif true, make the configuration GUI visible. If false, hide the config GUI if there is one.
Returns:
true if the module has a configuration GUI, else false.
virtual void StelModule::deinit ( ) [inline, virtual]

Called before the module will be delete, and before the openGL context is suppressed.

Deinitialize all openGL texture in this method.

virtual void StelModule::draw ( StelCore core) [inline, virtual]

Execute all the drawing functions for this module.

Parameters:
corethe core to use for the drawing

Reimplemented in ConstellationMgr, GridLinesMgr, LabelMgr, LandscapeMgr, MeteorMgr, MilkyWay, NebulaMgr, SolarSystem, StarMgr, StelMovementMgr, StelObjectMgr, StelSkyLayerMgr, and ScreenImageMgr.

virtual bool StelModule::drawPartial ( StelCore core) [virtual]

Iterate through the drawing sequence.

This allow us to split the slow drawing operation into small parts, we can then decide to pause the painting for this frame and used the cached image instead.

Returns:
true if we should continue drawing (by calling the method again)
virtual double StelModule::getCallOrder ( StelModuleActionName  actionName) const [inline, virtual]

Return the value defining the order of call for the given action For example if stars.callOrder[ActionDraw] == 10 and constellation.callOrder[ActionDraw] == 11, the stars module will be drawn before the constellations.

Parameters:
actionNamethe name of the action for which we want the call order
Returns:
the value defining the order. The closer to 0 the earlier the module's action will be called

Reimplemented in ConstellationMgr, GridLinesMgr, LabelMgr, LandscapeMgr, MeteorMgr, MilkyWay, NebulaMgr, SolarSystem, StarMgr, StelSkyLayerMgr, and ScreenImageMgr.

virtual void StelModule::handleKeys ( class QKeyEvent *  e) [inline, virtual]

Handle key events.

Please note that most of the interactions will be done through the GUI module.

Parameters:
ethe Key event
Returns:
set the event as accepted if it was intercepted

Reimplemented in StelMovementMgr.

virtual void StelModule::handleMouseClicks ( class QMouseEvent *  ) [inline, virtual]

Handle mouse clicks.

Please note that most of the interactions will be done through the GUI module.

Returns:
set the event as accepted if it was intercepted

Reimplemented in StelMovementMgr.

virtual bool StelModule::handleMouseMoves ( int  x,
int  y,
Qt::MouseButtons  b 
) [inline, virtual]

Handle mouse moves.

Please note that most of the interactions will be done through the GUI module.

Returns:
true if the event was intercepted

Reimplemented in StelMovementMgr.

virtual void StelModule::handleMouseWheel ( class QWheelEvent *  ) [inline, virtual]

Handle mouse wheel.

Please note that most of the interactions will be done through the GUI module.

Returns:
set the event as accepted if it was intercepted

Reimplemented in StelMovementMgr.

virtual void StelModule::init ( ) [pure virtual]

Initialize itself.

If the initialization takes significant time, the progress should be displayed on the loading bar.

Implemented in ConstellationMgr, StelGeodesicGridDrawer, GridLinesMgr, LabelMgr, LandscapeMgr, MeteorMgr, MilkyWay, NebulaMgr, SolarSystem, StarMgr, StelMovementMgr, StelObjectMgr, StelSkyLayerMgr, and ScreenImageMgr.

virtual void StelModule::update ( double  deltaTime) [pure virtual]

Update the module with respect to the time.

Parameters:
deltaTimethe time increment in second since last call.

Implemented in ConstellationMgr, StelGeodesicGridDrawer, GridLinesMgr, LabelMgr, LandscapeMgr, MeteorMgr, MilkyWay, NebulaMgr, SolarSystem, StarMgr, StelMovementMgr, StelObjectMgr, StelSkyLayerMgr, and ScreenImageMgr.
