te::qt::widgets::GroupingItem::~GroupingItem ( )

Destructor.

Member Function Documentation

void te::qt::widgets::TreeItem::addChild ( TreeItem * item )

inherited

Adds a child to the item. The child is added to the end of the list.

Parameters

item	The child to be inserted.

Qt::ItemFlags te::qt::widgets::GroupingItem::flags ( )

virtual

Returns the flags to be used by the model.

Returns: Qt flags. By default itens are enabled, editable and selectable. If you want to change the flags reimplement this method in a subclass.

Reimplemented from te::qt::widgets::TreeItem.

std::string te::qt::widgets::GroupingItem::getAsString ( ) const

virtual

Returns the label of the item to be presented in a Qt view.

Returns: The item label, to be presented in a Qt view.

Implements te::qt::widgets::TreeItem.

TreeItem* te::qt::widgets::TreeItem::getChild	(	const size_t &	pos	)	const
throw	(	te::common::Exception
	)

inherited

Returns the child located at pos.

Parameters

pos	The position of the desired child at the children list.

Returns: The child item located at pos.

Exceptions

If	pos is greater or equal than the children list size, a te::common::Exception will be raised.

void te::qt::widgets::TreeItem::getChildren	(	std::vector< TreeItem * > &	items,
		const std::string &	type
	)		const

inherited

Returns all children of a certain type.

Parameters

[out]	items	The set of items founded.
	type	The type of items that we are searching for.

size_t te::qt::widgets::TreeItem::getChildrenCount ( const std::string & type ) const

inherited

Returns the number of children.

The type, defines the type of children we want to considere in the operation. If an empty string is given as argument, all kinds of children will be considered.

Parameters

type	The type of children we want to calculate the number.

Returns: Number of children of type type.

TreeItem* te::qt::widgets::TreeItem::getParent ( ) const

inherited

Returns the item parent.

Returns: A pointer to the parent.

int te::qt::widgets::TreeItem::getPosition ( )

inherited

Returns the position of item in its parent's list of children.

Returns: The position of item in its parent's list of children.

std::string te::qt::widgets::TreeItem::getToolTip ( ) const

inherited

Returns the item tooltip (for information purposes).

Returns: The item tooltip.

std::string te::qt::widgets::TreeItem::getType ( ) const

inherited

Returns the type of the item.

Returns: Type of the item.

bool te::qt::widgets::TreeItem::hasChildren ( ) const

inherited

Tells us if the item has children or not.

Returns: True if children list is not empty and false otherwise.

void te::qt::widgets::TreeItem::insertChild	(	TreeItem *	item,
		const size_t &	pos
	)
throw	(	te::common::Exception
	)

inherited

Inserts a child item at the desired position.

Parameters

item	The child to be inserted.
pos	The position of the child in the children list.

Exceptions

If	pos is greater than the children list size, a te::common::Exception will be raised.

VISIBLE te::qt::widgets::GroupingItem::isVisible ( ) const

virtual

Returns the visibilty state of the item.

Returns: The state of visibilty of the item.

Reimplemented from te::qt::widgets::TreeItem.

void te::qt::widgets::TreeItem::removeAllChilds ( )

inherited

Removes all children.

TreeItem* te::qt::widgets::TreeItem::removeChild	(	const size_t &	pos	)
throw	(	te::common::Exception
	)

inherited

Removes the child located at pos from the children list.

Parameters

pos	The position of the desired child at the children list.

Returns: The removed item.

Exceptions

If	pos is greater or equal than the children list size, a te::common::Exception will be raised.

void te::qt::widgets::TreeItem::setParent ( TreeItem * item )

inherited

Updates the item parent.

Parameters

item	The new parent.

void te::qt::widgets::GroupingItem::setVisible	(	const VISIBLE &	visible,
		const bool &	updateAncestors = `false`,
		const bool &	updateDescendents = `false`
	)

virtual

Updates the visibilty state of the item.

Parameters

visible	The new visibility state.
updateAncestors	Updates also ancestors states.
updateDescendents	Updates also descendents states.

Reimplemented from te::qt::widgets::TreeItem.
