Detailed Description

MainControl is the main administration unit for a program and must be used by all applications. MainControl is also derived from Qt::QMainWindow and therefore the main widget of an application must be derived from this class. Further it has the necessary interface methods to create and update the menus of the main application.

MainControl is also a storage facility for Composite objects, the graphical Representation and the inserted ModularWidget. The interface for the Composite administration is implemented in CompositeManager, and for the Representation 's in RepresentationManager. Specialized methods exists for the adding, updateing and removing of Composites as well as Representations. (see the update, insert and remove methods)

This class is also the root ConnectionObject and thus it is responsible for the handling of all messages. To add ModularWidgets all that is necessary are the creation of the derived modular widgets with the MainControl as their parents like e.g.
new DisplayProperties(this, "DisplayProperties");
For examples have a look at BALL/source/APPLICATIONS/mainframe.C

MainControl also handles the Preferences dialog (and it's tab entry for some general preferences) and notifies all registered ModularWidgets if the preferences have changed. The content of the Preferences dialog with all setup options is stored in an INIFile. The default name of this file is ".BALLView".

See also:: writePreferences; fetchPreferences; saveBALLViewProjectFile; loadBALLViewProjectFile

Caveat: Due to a peculiarity of the QT Meta Object Compiler (MOC) you have to specify the full namespace qualified name of this class when deriving from it.

: So don't use
class foo : public MainControl ; but
class foo : public BALL::VIEW::MainControl instead.

virtual void BALL::VIEW::MainControl::show ( ) [virtual, slot]

Initialize all registered ModularWidget objects. It initializes the menu structure, the preferences dialogs and connects every ModularWidget with the MainControl. This method also creates the first menu entry FILE with its subentry EXIT to exit the application. See ModularWidget for further information concerning menu structure creation and preferences handling.

: Calls registerConnectionObject()

: Calls fetchPreferences()

: Calls applyPreferences()

: Calls insertMenuEntry()

: Calls ModularWidget::initializeWidget()

: Calls QMainWindow::show()

: Note: Call this method to start the application.

Reimplemented in BALL::Mainframe.

bool BALL::VIEW::MainControl::stopedSimulation ( ) [inline]

Returns true, if the simulation was told to stop, but hasnt done this so far.

Definition at line 559 of file mainControl.h.

void BALL::VIEW::MainControl::stopedSimulation_ ( ) [protected]

void BALL::VIEW::MainControl::stopSimulation ( ) [slot]

Stop a currently running calculation.

void BALL::VIEW::MainControl::toggleFullScreen ( ) [slot]

bool BALL::VIEW::MainControl::unlockCompositesFor ( ModularWidget * widget )

Lock the Composites for a given Modular Widget.

void BALL::VIEW::MainControl::update	(	Composite &	composite,
		bool	changed_hierarchy = `true`
	)

Update a Composite in all ModularWidget. This method differs wheter the composites hierarchy was changed or not. The update is faster if the hierarchy is unchanged, because e.g. the MolecularControl doesnt have to rebuild the ListViewItem tree. A CompositeMessage with type CHANGED_COMPOSITE or CHANGED_COMPOSITE_HIERARCHY is send and updateRepresentationsOf(composite) is called.

Returns:: false if the CompositeManager doesnt contain the Composite

bool BALL::VIEW::MainControl::update ( Representation & rep )

Update a Representation A RepresentationMessage with type UPDATE and a SceneMessage is send.

Returns:: false if the RepresentationManager doesnt contain the Representation

bool BALL::VIEW::MainControl::updateOfRepresentationRunning ( )

Return true if Representations are (re)calculated.

void BALL::VIEW::MainControl::updateRepLabel_ ( ) [protected, slot]

bool BALL::VIEW::MainControl::updateRepresentationsOf	(	const Composite &	composite,
		bool	rebuild = `true`,
		bool	force = `false`
	)

Redraws all Representation objects for a Composite. If the Composite is not inserted into this MainControl false will be returned. updateRepresentationsOf() is called after receiving a CompositeMessage with type CHANGED_COMPOSITE in onNotify(). It sends a RepresentationMessage with type UPDATE for every Representation, which was build for the Composite. After this a SceneMessage is send to redraw the Scene.

: Notes: If you changed a Composite in MainControl or a derived class, the MainControl doesnt get notified, from the CompositeMessage it sends. So you have to call this function instead of sending the message.

Parameters:

	composite	the Composite that should be updated
	rebuild	if set to true, the model is rebuilded, otherwise just the coloring is updated
	force	is set to true, also rebuild non surface models (only usefull with rebuild = true)

Returns:: true if an update was performed

bool BALL::VIEW::MainControl::useMultithreading ( )

Method to query if multithreading is enabled. Multithreaded code is used for serveral functions:

Update of Representations
Simulations
Download PDB files

To debug such code it is often usefull to to be able to run it in a singlethreaded mode. Every piece of multithreaded code should therefore call this method and decide if it should run without multiple threads. Furthermore most of the time, valid benchmark results can only be achived with one single thread.

void BALL::VIEW::MainControl::wait ( )

Wait until the MainControl is not busy anymore.

virtual void BALL::VIEW::MainControl::writePreferences ( INIFile & inifile ) [virtual]

Writes the widgets preferences to the INIFile. Calls writePreferences() for all registered ModularWidgets and Preferences::savePreferences(). Note: If this method is overridden, call this method at the end of the overriden method to make sure that the general preferences are written.

Parameters:

inifile

the INIFile that contains the needed values
