Detailed Description

The filetreeview offers a treeview on the file system which behaves like a QTreeView showing files and/or directories in the file system.

KFileTreeView is able to handle more than one URL, represented by KFileTreeBranch.

Typical usage: 1. create a KFileTreeView fitting in your layout and add columns to it 2. call addBranch to create one or more branches 3. retrieve the root item with KFileTreeBranch::root() and set it open if desired. That starts the listing.

Member Function Documentation

KFileTreeViewItem * KFileTreeView::currentKFileTreeViewItem (    ) 
 

Returns:
the current (i.e. selected) item

Definition at line 557 of file kfiletreeview.cpp.

References QListView::selectedItem().

Referenced by currentURL().

KURL KFileTreeView::currentURL (    ) 
 

Returns:
the URL of the current selected item.

Definition at line 562 of file kfiletreeview.cpp.

Referenced by KDirSelectDialog::url().

KFileTreeBranch * KFileTreeView::addBranch (  const KURL &    path,
const QString &    name,
bool    showHidden = false
) 
 

Adds a branch to the treeview item.

This high-level function creates the branch, adds it to the treeview and connects some signals. Note that directory listing does not start until a branch is expanded either by opening the root item by user or by setOpen on the root item.

Returns:
a pointer to the new branch or zero
Parameters:
path  is the base url of the branch
name  is the name of the branch, which will be the text for column 0
showHidden  says if hidden files and directories should be visible

KFileTreeBranch * KFileTreeView::addBranch (  const KURL &    path,
const QString &    name,
const QPixmap &    pix,
bool    showHidden = false
)  [virtual]
 

same as the function above but with a pixmap to set for the branch.

References QPtrList< KFileTreeBranch >::append().

bool KFileTreeView::removeBranch (  KFileTreeBranch *    branch )  [virtual]
 

removes the branch from the treeview.

Parameters:
branch  is a pointer to the branch
Returns:
true on success.

References QPtrList< KFileTreeBranch >::contains(), QPtrList< KFileTreeBranch >::remove(), and KFileTreeBranch::root().

KFileTreeBranch * KFileTreeView::branch (  const QString &    searchName ) 
 

Returns:
a pointer to the KFileTreeBranch in the KFileTreeView or zero on failiure.
Parameters:
branchno  is the name of a branch

KFileTreeBranchList & KFileTreeView::branches (    ) 
 

Returns:

Definition at line 389 of file kfiletreeview.cpp.

void KFileTreeView::setDirOnlyMode (  KFileTreeBranch *    brnch,
bool   
)  [virtual]
 

set the directory mode for branches.

If true is passed, only directories will be loaded.

Parameters:
branch  is a pointer to a KFileTreeBranch

KFileTreeViewItem * KFileTreeView::findItem (  KFileTreeBranch *    brnch,
const QString &    relUrl
) 
 

searches a branch for a KFileTreeViewItem identified by the relative url given as second parameter.

The method adds the branches base url to the relative path and finds the item.

Returns:
a pointer to the item or zero if the item does not exist.
Parameters:
brnch  is a pointer to the branch to search in
relUrl  is the branch relativ url

bool KFileTreeView::showFolderOpenPixmap (    )  const [inline]
 

Returns:
a flag indicating if extended folder pixmaps are displayed or not.

Definition at line 152 of file kfiletreeview.h.

virtual void KFileTreeView::setShowFolderOpenPixmap (  bool    showIt = true )  [inline, virtual, slot]
 

set the flag to show 'extended' folder icons on or off.

If switched on, folders will have an open folder pixmap displayed if their children are visible, and the standard closed folder pixmap (from mimetype folder) if they are closed. If switched off, the plain mime pixmap is displayed.

Parameters:
showIt  = false displays mime type pixmap only

bool KFileTreeView::acceptDrag (  QDropEvent *    event )  const [protected, virtual]
 

Returns:
true if we can decode the drag and support the action
