## Member Typedef Documentation

## ◆ ChildObjectMap

typedef QHash<const UMLObject*, UMLListViewItem*> UMLListViewItem::ChildObjectMap
| protected

Auxiliary map of child UMLListViewItems keyed by UMLObject. Used by findChildObject() for efficiency instead of looping using firstChild()/nextSibling() because the latter incur enforceItemVisible() and thus expensive sorting.

## Member Function Documentation

## ◆ addChildItem()

void UMLListViewItem::addChildItem | ( | UMLObject * | child,
|  | UMLListViewItem * | childItem )

Adds to the child object cache the child listview item representing the given UMLObject.

Parameters

  child | Pointer to UMLObject serving as the key into s_comap
  item | Pointer to UMLListViewItem to be returned as the value keyed by child

## ◆ cancelRenameWithMsg()

void UMLListViewItem::cancelRenameWithMsg | ( |  | ) |
| protected

Auxiliary method for okRename().

## ◆ childItem()

UMLListViewItem * UMLListViewItem::childItem | ( | int | i | ) |

## ◆ deepCopy()

UMLListViewItem * UMLListViewItem::deepCopy | ( | UMLListViewItem * | newParent | ) |

Overrides the default sorting to sort by item type. Sort the listview items by type and position within the corresponding list of UMLObjects. If the item does not have a UMLObject then place it last.

Create a deep copy of this UMLListViewItem, but using the given parent instead of the parent of this UMLListViewItem. Return the new UMLListViewItem created.

## ◆ deleteChildItem()

void UMLListViewItem::deleteChildItem | ( | UMLObject * | child | ) |

Deletes the child listview item representing the given UMLObject.

## ◆ deleteItem()

void UMLListViewItem::deleteItem | ( | UMLListViewItem * | childItem | ) |
| static

Deletes the given child listview item representing a UMLObject.

## ◆ findChildObject()

UMLListViewItem * UMLListViewItem::findChildObject | ( | const UMLObject * | child | ) |

Find the UMLListViewItem that represents the given UMLObject in the children of the current UMLListViewItem. Return a pointer to the item or NULL if not found.

## ◆ findItem()

UMLListViewItem * UMLListViewItem::findItem | ( | Uml::ID::Type | id | ) |

Find the UMLListViewItem of the given ID in the tree rooted at the current UMLListViewItem. Return a pointer to the item or NULL if not found.

Parameters

  id | The ID to search for.

Returns
  The item with the given ID or NULL if not found.

## ◆ findUMLObject()

UMLListViewItem * UMLListViewItem::findUMLObject | ( | const UMLObject * | o | ) |

Find the UMLListViewItem that is related to the given UMLObject in the tree rooted at the current UMLListViewItem. Return a pointer to the item or NULL if not found.

## ◆ findUMLObject_r()

UMLListViewItem * UMLListViewItem::findUMLObject_r | ( | const UMLObject * | o | ) |
| protected

Auxiliary function for findUMLObject: Search recursively in child hierarchy.

## ◆ getSavedText()

QString UMLListViewItem::getSavedText | ( |  | ) | const

Returns the saved text.

## ◆ ID()

Returns the id this class represents.

Returns
  The id this class represents.

## ◆ init()

void UMLListViewItem::init | ( |  | ) |
| protected

Initializes key variables of the class.

## ◆ isOpen()

bool UMLListViewItem::isOpen | ( |  | ) | const
| inline

## ◆ isOwnParent()

bool UMLListViewItem::isOwnParent | ( | Uml::ID::Type | listViewItemID | ) |

Returns true if the UMLListViewItem of the given ID is a parent of this UMLListViewItem.

## ◆ loadFromXMI()

bool UMLListViewItem::loadFromXMI | ( | QDomElement & | qElement | ) |

Loads a "listitem" tag, this is only used by the clipboard currently.

## ◆ saveToXMI()

Set the pixmap corresponding to the given IconType.

## ◆ setID()
