Constructor & Destructor Documentation

KFileTreeBranch::KFileTreeBranch ( KFileTreeView ,
const KURL &  url,
const QString name,
const QPixmap pix,
bool  showHidden = false,
KFileTreeViewItem branchRoot = 0 
)

constructs a branch for KFileTreeView.

Does not yet start to list it.

Parameters:
url start url of the branch.
name the name of the branch, which is displayed in the first column of the treeview.
pix is a pixmap to display as an icon of the branch.
showHidden flag to make hidden files visible or not.
branchRoot is the KFileTreeViewItem to use as the root of the branch, with the default 0 meaning to let KFileTreeBranch create it for you.

Member Function Documentation

KURL KFileTreeBranch::rootUrl (  )  const [inline]

Returns:
the root url of the branch.

Definition at line 69 of file kfiletreebranch.h.

virtual void KFileTreeBranch::setRoot ( KFileTreeViewItem r  )  [inline, virtual]

sets a KFileTreeViewItem as root widget for the branch.

That must be created outside of the branch. All KFileTreeViewItems the branch is allocating will become children of that object.

Parameters:
r the KFileTreeViewItem to become the root item.

Definition at line 77 of file kfiletreebranch.h.

KFileTreeViewItem* KFileTreeBranch::root (  )  [inline]

Returns:
the root item.

Definition at line 82 of file kfiletreebranch.h.

QString KFileTreeBranch::name (  )  const [inline]

Returns:
the name of the branch.

Definition at line 87 of file kfiletreebranch.h.

virtual void KFileTreeBranch::setName ( const QString  n  )  [inline, virtual]

sets the name of the branch.

Definition at line 92 of file kfiletreebranch.h.

bool KFileTreeBranch::showExtensions (  )  const

Returns:
whether the items in the branch show their file extensions in the tree or not.

See setShowExtensions for more information.

Definition at line 269 of file kfiletreebranch.cpp.

void KFileTreeBranch::setOpen ( bool  setopen = true  )  [inline]

sets the root of the branch open or closed.

Definition at line 120 of file kfiletreebranch.h.

void KFileTreeBranch::setChildRecurse ( bool  t = true  ) 

sets if children recursion is wanted or not.

If this is switched off, the child directories of a just opened directory are not listed internally. That means that it can not be determined if the sub directories are expandable or not. If this is switched off there will be no call to setExpandable.

Parameters:
t set to true to switch on child recursion

Definition at line 256 of file kfiletreebranch.cpp.

bool KFileTreeBranch::childRecurse (  )  [inline]

Returns:
if child recursion is on or off.

See also:
setChildRecurse

Definition at line 137 of file kfiletreebranch.h.

bool KFileTreeBranch::populate ( const KURL &  url,
KFileTreeViewItem currItem 
) [virtual, slot]

populates a branch.

This method must be called after a branch was added to a KFileTreeView using method addBranch.

Parameters:
url is the url of the root item where the branch starts.
currItem is the current parent.

Definition at line 495 of file kfiletreebranch.cpp.

void KFileTreeBranch::setShowExtensions ( bool  visible = true  )  [virtual, slot]

sets printing of the file extensions on or off.

If you pass false to this slot, all items of this branch will not show their file extensions in the tree.

Parameters:
visible flags if the extensions should be visible or not.

Definition at line 264 of file kfiletreebranch.cpp.

KFileTreeViewItem * KFileTreeBranch::createTreeViewItem ( KFileTreeViewItem parent,
KFileItem *  fileItem 
) [protected, virtual]

allocates a KFileTreeViewItem for the branch for new items.

Definition at line 239 of file kfiletreebranch.cpp.

KFileTreeViewItem * KFileTreeBranch::findTVIByURL ( const KURL &   )  [virtual]

find the according KFileTreeViewItem by an url

Definition at line 368 of file kfiletreebranch.cpp.

void KFileTreeBranch::populateFinished ( KFileTreeViewItem  )  [signal]

emitted with the item of a directory which was finished to populate

void KFileTreeBranch::newTreeViewItems ( KFileTreeBranch ,
const KFileTreeViewItemList  
) [signal]

emitted with a list of new or updated KFileTreeViewItem which were found in a branch.

Note that this signal is emitted very often and may slow down the performance of the treeview !

void KFileTreeBranch::directoryChildCount ( KFileTreeViewItem item,
int  count 
) [signal]

emitted with the exact count of children for a directory.
