## 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 | ( |  | ) | const

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

Definition at line 586 of file kfiletreeview.cpp.

References QListView::selectedItem().

Referenced by currentURL().

KURL KFileTreeView::currentURL | ( |  | ) | const

Returns:
  the URL of the current selected item.

Definition at line 591 of file kfiletreeview.cpp.

References currentKFileTreeViewItem(), and KFileTreeViewItem::url().

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. Definition at line 365 of file kfiletreeview.cpp. References addBranch(), endl(), and kdDebug().

KFileTreeBranch * KFileTreeView::addBranch | ( | KFileTreeBranch * |  | ) | `[virtual]`

| same as the function above but letting the user create the branch. Definition at line 376 of file kfiletreeview.cpp. References QPtrList::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.

Definition at line 414 of file kfiletreeview.cpp.

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

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

Returns:
  a pointer to the KFileTreeBranch in the KFileTreeView or zero on failure.

Parameters:

  | searchName | is the name of a branch

Definition at line 390 of file kfiletreeview.cpp.

References QPtrListIterator::current(), endl(), kdDebug(), and KFileTreeBranch::name().

Referenced by findItem().

KFileTreeBranchList & KFileTreeView::branches | ( |  | ) |

Returns:
  a list of pointers to all existing branches in the treeview.

Definition at line 408 of file kfiletreeview.cpp.

void KFileTreeView::setDirOnlyMode | ( | KFileTreeBranch * | branch,
|  | 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

Definition at line 428 of file kfiletreeview.cpp.

References KDirLister::setDirOnlyMode().

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

KFileTreeViewItem * KFileTreeView::findItem | ( | const QString & | branchName,
|  | const QString & | relUrl
| ) |

| see method above, differs only in the first parameter. Finds the branch by its name. Definition at line 619 of file kfiletreeview.cpp. References branch(), and findItem().

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

Definition at line 163 of file kfiletreeview.h.

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

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

Reimplemented from KListView.
