Detailed Description

Defines an abstract model based on TreeItem objects.

Models are used by the item views of the Qt5 that represents some data structure. Its used for manipulate models using a view. This is part of the Model / View framework of the Qt5.

Constructor & Destructor Documentation

◆ LayerItemModel()

te::qt::widgets::LayerItemModel::LayerItemModel ( QObject * parent = 0 )

explicit

Constructor.

Parameters

parent Model parent (Used by Qt5).

References parent().

◆ ~LayerItemModel()

te::qt::widgets::LayerItemModel::~LayerItemModel ( )

Destructor.

Member Function Documentation

◆ addFolder() [1/2]

void te::qt::widgets::LayerItemModel::addFolder	(	const std::string &	name,
		const QModelIndex &	idx )

Adds a new folder item to the model.

Parameters

name	Label of the folder.
idx	The parent of the new FolderItem.

◆ addFolder() [2/2]

void te::qt::widgets::LayerItemModel::addFolder	(	const std::string &	name,
		TreeItem *	parent = 0 )

Adds a new folder item to the model.

Parameters

name	Label of the folder.
parent	Parent item. If this value is "0" the folder is added to the root of the model.

References parent().

◆ addItems()

void te::qt::widgets::LayerItemModel::addItems	(	const std::vector< TreeItem * >	items,
		TreeItem *	parent,
		const int &	pos = 0 )

Adds the set of items to the parent at the position pos.

These methods is used when you needs to reparent some items. It is a common operation on the view, like a drag and drop operation, for example. The items are removed from its parents and added in the parent, as children.

Parameters

items	The items to be reparent.
parent	The new parent, where the items must be inserted.
pos	The position where the items must be inserted.

Note: If pos is greater than the size of the list of children, items are, then, added to end of the list of children.; If you want to add items to the root, try to pass "0" as value for parent argument.
