Detailed Description

Tree item containing vector of PDF operators.

Tree item holding vector with pdf operators The vector is specified in constructor and comes from arbitrary source (usually selected objects from page)

Member Function Documentation

TreeItemAbstract * gui::TreeItemOperatorContainer::createChild ( const QString &  name,
ChildType  typ,
Q_ListViewItem *  after = NULL 
) [virtual]

Create one subchild

Parameters:
name Name of child (the same as in list returned from getChildNames)
typ Type of TreeItemAbstract's child. (see ChildType)
after Q_ListViewItem after which will be this item added. If unspecified (or NULL), it is added before any other items
Returns:
Pointer to subchild. If returned NULL, the subchild can not be created

getChildNames

Implements gui::TreeItemAbstract.

QStringList gui::TreeItemOperatorContainer::getChildNames (  )  [virtual]

Get list of all item's childs names

Returns:
list of child names. Names in the list must be unique and the list may be empty.

Implements gui::TreeItemAbstract.

ChildType gui::TreeItemOperatorContainer::getChildType ( const QString &  name  )  [virtual]

Get type of this items child, given its name.

Parameters:
name Name of child item
Returns:
type of specified child

Implements gui::TreeItemAbstract.

QSCObject * gui::TreeItemOperatorContainer::getQSObject (  )  [virtual]

Create and return object for scripting representing this tree item

Returns:
object for scripting

Implements gui::TreeItemAbstract.

References util::countList(), and op.

bool gui::TreeItemOperatorContainer::haveChild (  )  [virtual]

Return true, if the item have at least one child

Returns:
Presence of at least one child

Implements gui::TreeItemAbstract.

void gui::TreeItemOperatorContainer::init ( const QString &  name  )  [private]

initialize captions of this item from name

Parameters:
name Caption of item
void gui::TreeItemOperatorContainer::reloadSelf (  )  [virtual]

Reload contents of itself and only itself (excluding any children)

Implements gui::TreeItemAbstract.

void gui::TreeItemOperatorContainer::remove (  )  [virtual]

Remove itself from document (including any children) Do not remove the treeitem itself in this method -> this may lead to crash! If desired, you may call reload() on parent to get rid of the item correctly

Implements gui::TreeItemAbstract.

bool gui::TreeItemOperatorContainer::validChild ( const QString &  name,
Q_ListViewItem *  oldChild 
) [virtual]

Validate child, given its name and reference to old child Usually it is valid, since item with same name refer to same subitem (key-based items), but for value-based items (array) same keys can correspond to different values after reloading. In such cases, false should be returned. Also, similar problems can happen when switching revisions (with almost all types)

Note: false negative it not a problem (only unnecessary reloading), while false positive mean the tree is invalid/outdated

Parameters:
name name of (old and new) treeitem
oldChild reference to old child tree item
Returns:
True, if the old child is pointing to same item as item "name", false, if the child item "name" no longer point to same item as oldChild.

Implements gui::TreeItemAbstract.
