Detailed Description

Allows access to items in a ProjectItemModel through a proxy model.

A proxy model can have a different structure than the source model. An item in the proxy model usually corresponds to an item in the source model. The proxy model will update item selections and the current item between the source model and the proxy model.

In the default implementation the only items in the proxy model are item that are added with the addItem() method. The items that are added are organized in the same tree structure that they are in the source model. Subclasses of ProjectItemProxyModel can organize items in a different way by overriding the addItem() method.

The proxy model ensures that its item selection corresponds to the item selection in the source model. When the selection in the proxy model changes the selection in the source model is changed to the items that correspond to the items in the proxy selection. Similarly when the selection in the source model is changed the selection in the proxy model is changed to the items in the proxy model that correpond to the items in the selection.

ProjectItemModel *model = new ProjectItemModel(this);
model->addProject(project);
ProjectItemProxyModel *proxyModel = new ProjectItemProxyModel(this);
proxyModel->setSourceModel(model);
for (int i=0; i < model.rowCount(); i++) {
  proxyModel->addItem( model->item(i) );
}

Constructor & Destructor Documentation

◆ ProjectItemProxyModel()

Isis::ProjectItemProxyModel::ProjectItemProxyModel ( QObject * parent = 0 )

Constructs the proxy model.

Parameters

[in] parent (QObject *) The parent QObject.

Definition at line 44 of file ProjectItemProxyModel.cpp.

References m_sourceModel.

Member Function Documentation

◆ addChild()

ProjectItem * Isis::ProjectItemProxyModel::addChild	(	ProjectItem *	sourceItem,
		ProjectItem *	parentItem
	)

protected

Creates an item in the proxy model corresponding to an item in the source model as a child of a parent item in the proxy model.

If the corresponding item in the proxy model already exits then that item is updated instead of creating a new item. If the corresponding item already has a parent its parent is changed to the new parent. If the parent item is null then the item is added as a top-level item in the model.

Parameters

[in]	sourceItem	(ProjectItem *) The item in the source model.
[in]	parentItem	(ProjectItem *) The parent in the proxy model.

Returns: ProjectItem* The correponding item in the proxy model.

◆ addItem

ProjectItem * Isis::ProjectItemProxyModel::addItem ( ProjectItem * sourceItem )

slot

Adds an item and its children to the proxy model.

Creates items in the proxy model from an item in the source model and returns the created item. If the item in the source model has already been added, then the corresponding item in the proxy model is updated and returned instead.

When an item in the source model is added the children of that item are also added as children of the corresponding item in the proxy model.

Parameters

[in] sourceItem (ProjectItem *) The item in the source model.

Returns: ProjectItem* The item in the proxy model.
