void NSCore::MathTreeRoot::deleteMe	(	MathExpression *	exp,
		NSCore::GuiServer_Interface *	gui
	)			[virtual]

delete items in a thread-save way...

...by handing the action to the parent until it gets handled in a different way.

Reimplemented from NSCore::MathExpression.

void NSCore::MathTreeRoot::addChild	(	MathExpression *	pexp,
		NSCore::GuiServer_Interface *	gui
	)			[virtual]

add new items in a thread-save way...

...by handing the action to the parent until it gets handled in a different way.

Reimplemented from NSCore::MathExpression.

double NSCore::MathTreeRoot::value

(

AcqisitionDataSet &

)

[virtual]

Abstract function that does the work.

This has to be implemented to do the work.

Implements NSCore::MathExpression.

Reimplemented in NSEvaluation::FilterExpression.

QStringList NSCore::MathTreeRoot::guiActions

(

)

const [inline, virtual]

GUI: return the supported actions.

These actions will get symbols/buttons to get executed.

If you implement this, remember to call the parent guiActions() too:

 SomeTreeItem::guiActions() const {
   return QStringList() << <your actions> << BaseClass::guiActions();
 }

Reimplemented from NSCore::MathExpression.

References NSCore::QTreeItem::guiActions().

void NSCore::MathTreeRoot::guiExecAction	(	QString	n,
		GuiServer_Interface *	gui
	)			[virtual]

GUI: execute the named action.

If you implemented guiActions() you will also want to implement this. If you can't handle the named action yourself, call guiExecAction() of the parent class.

Of course this can also be used as a filter if you want to restrict access to actions of the parent class.

The second parameter lets you interact with the user by some basic means.

Parameters:

	n	The action to execute
	gui	The gui to use for interactions

Reimplemented from NSCore::MathExpression.

void NSCore::MathTreeRoot::setSingleChild

(

bool

n

)

[inline]

bool NSCore::MathTreeRoot::singleChild

const [inline]

void NSCore::MathTreeRoot::workOnCache

(

)

[private, slot]

QString NSCore::MathTreeRoot::debug

(

)

const [inline, private, virtual]

Custom debug text.

This function has to be implemented and has to return the internal debug-data that is to be printed...

Implements NSCore::QTreeItem.

Reimplemented in NSEvaluation::FilterExpression.

QDomNode NSCore::MathTreeRoot::saveToXML

(

QDomDocument

doc

)

[private, virtual]

Store the information of this element into a new QDomElement.

This function is only to save the state of this element, all the recursive stuff will be done by toXml().

Parameters:

doc

The QDomDocument to use for creation of the element

Implements NSCore::QTreeItem.

Reimplemented in NSEvaluation::FilterExpression.

bool NSCore::MathTreeRoot::restoreFromXML

(

QDomNode

node

)

[private, virtual]

Restore the state of this element from the given QDomNode.

You don't have to do the recursive stuff here, that is handled in fromXml() for you. Only the things done in saveToXML need/can be restored here.

If you succeeded and want the childs to be restored too, return true.

Parameters:

node

The QDomNode to restore from

Implements NSCore::QTreeItem.

Reimplemented in NSEvaluation::FilterExpression.

bool NSCore::MathTreeRoot::createFromXML

(

QDomNode

node

)

[private, virtual]

Create childs from XML.

On fromXml() this gets called after successfull return from restoreFromXML(). If you want to create childs of this item from the childs of the QDomNode given, you can do so.

The return value defines whether fromXml will be called on the childs for the child-xml-items.

The default implementation returns true, so the child items get a chance to restore their state too.

Parameters:

node

The QDomNode to restore from

Reimplemented from NSCore::QTreeItem.
