This Widget extends the functionality of QListView to honor the system wide settings for Single Click/Double Click mode, AutoSelection and ChangeCursorOverLink (TM).
There is a new signal executed(). It gets connected to either QListView::clicked() or QListView::doubleClicked() depending on the KDE wide Single Click/Double Click settings. It is strongly recommended that you use this signal instead of the above mentioned. This way you donīt need to care about the current settings. If you want to get informed when the user selects something connect to the QListView::selectionChanged() signal.
Drag-and-Drop is supported with the signal dropped(), just setAcceptDrops(true) and connect it to a suitable slot. To see where you are dropping, setDropVisualizer(true). And also you'll need acceptDrag(QDropEvent*)
KListView is drag-enabled, too: to benefit from that you've got derive from it. Reimplement dragObject() and (possibly) startDrag(), and setDragEnabled(true).
| enum SelectionModeExt { Single = QListView::Single, Multi = QListView::Multi, Extended = QListView::Extended, NoSelection = QListView::NoSelection, Konqueror } | SelectionModeExt |
Possible selection modes.
The first four correspond directly to QListView::SelectionMode, while the Konqueror selection mode is defined as follows:
The combinations work the same with SHIFT instead of CTRL, except that if you start selecting something using SHIFT everything selected before will be deselected first.
This way e.g. SHIFT+up/PgUp then SHIFT+down/PgDn leaves no item selected
| KListView (QWidget *parent = 0, const char *name = 0)
| KListView |
Constructor.
The parameters parent and name are handled by
QListView, as usual.
| ~KListView ()
| ~KListView |
[virtual]
Destructor.
| void setAcceptDrops (bool)
| setAcceptDrops |
[virtual]
Reimplemented for internal reasons. Further reimplementations should call this function or else some features may not work correctly.
The API is unaffected.
| bool isExecuteArea ( const QPoint& point )
| isExecuteArea |
[virtual]
This function determines whether the given coordinates are within the execute area. The execute area is the part of a QListViewItem where mouse clicks or double clicks respectively generate a executed() signal. Depending on QListView::allColumnsShowFocus() this is either the whole item or only the first column.
Returns: true if point is inside execute area of an item, false in all other cases including the case that it is over the viewport.
| bool isExecuteArea ( int x )
| isExecuteArea |
Same thing, but from an x coordinate only. This only checks if x is in the first column (if all columns don't show focus), without testing if the y coordinate is over an item or not.

| alternateBackground |
[const]
Returns: the alternate background color
| void executed ( QListViewItem *item )
| executed |
[signal]
This signal is emitted whenever the user executes an listview item. That means depending on the KDE wide Single Click/Double Click setting the user clicked or double clicked on that item.
Note that you may not delete any QListViewItem objects in slots connected to this signal.
Parameters:
| item | is the pointer to the executed listview item. |
| void executed ( QListViewItem *item, const QPoint &pos, int c )
| executed |
[signal]
This signal is emitted whenever the user executes an listview item. That means depending on the KDE wide Single Click/Double Click setting the user clicked or double clicked on that item.
Note that you may not delete any QListViewItem objects in slots connected to this signal.
Parameters:
| item | is the pointer to the executed listview item. |
| pos | is the position where the user has clicked |
| c | is the column into which the user clicked. |
| void doubleClicked ( QListViewItem *item, const QPoint &pos, int c )
| doubleClicked |
[signal]
This signal gets emitted whenever the user double clicks into the listview.
Note that you may not delete any QListViewItem objects in slots connected to this signal.
This signal is more or less here for the sake of completeness. You should normally not need to use this. In most cases itīs better to use executed() instead.
Parameters:
| item | is the pointer to the clicked listview item. |
| pos | is the position where the user has clicked, and |
| c | is the column into which the user clicked. |
Reimplemented from QListView.
| void dropped (QDropEvent * e, QListViewItem *after)
| dropped |
[signal]
This signal gets emitted whenever something acceptable is dropped onto the listview.
Parameters:
| e | is the drop event itself (it has already been accepted) |
| after | is the item after which the drop occured (or 0L, if the drop was above all items) |
See also: acceptDrop()
| void dropped (KListView* list, QDropEvent* e, QListViewItem* after)
| dropped |
[signal]
This signal gets emitted whenever something acceptable is dropped onto the listview.
This is an overloaded version of the above (provided to simplify processing drops outside of the class).
Parameters:
| list | is the listview |
| e | is the drop event itself (it has already been accepted) |
| after | is the item after which the drop occured (or 0L, if the drop was above all items |
| void dropped (KListView* list, QDropEvent* e, QListViewItem* parent, QListViewItem* after)
| dropped |
[signal]
This signal gets emitted whenever something acceptable is dropped onto the listview.
This function also provides a parent, in the event that your listview is a tree
Parameters:
| list | is the listview |
| e | is the drop event itself (it has already been accepted) |
| parent | the item that is to be the parent of the new item |
| after | is the item after which the drop occured (or 0L, if the drop was above all items |
| void dropped (QDropEvent* e, QListViewItem* parent, QListViewItem* after)
| dropped |
[signal]
This signal gets emitted whenever something acceptable is dropped onto the listview.
This function also provides a parent, in the event that your listview is a tree
Parameters:

| parent | the item that is to be the parent of the new item |
| after | is the item after which the drop occured (or 0L, if the drop was above all items |
| void moved ()
| moved |
[signal]
This signal is emitted when ever the user moves an item in the list via DnD. If more than one item is moved at the same time, this signal is only emitted once.
| void aboutToMove ()
| aboutToMove |
[signal]
Connect to this signal if you want to do some preprocessing before a move is made, for example, to disable sorting
This is sent only once per each groups of moves. That is, for each drop that is a move this will be emitted once, before KListView calls moveItem()
| void moved (QListViewItem *item, QListViewItem *afterFirst, QListViewItem *afterNow)
| moved |
[signal]
This signal is emitted when ever the user moves an item in the list via
DnD.
If more than one item is moved at the same time, afterFirst and
afterNow will reflect what was true before the move.
This differs from moved(), so be careful. All the items will have been
moved before moved() is emitted, which is not true in this method. // FIXME
Parameters:
| item | the item that was moved |
| afterFirst | the item that parameter item was in before the move, in the list |
| afterNow | the item it's currently after. |
| void moved (QList<QListViewItem> &items, QList<QListViewItem> &afterFirst, QList<QListViewItem> &afterNow)
| moved |
[signal]
This signal is emitted after all the items have been moved. It reports info for
each and every item moved, in order. The first element in items associates
with the first of afterFirst and afterNow.
| void itemRenamed (QListViewItem* item, const QString &str, int col)
| itemRenamed |
[signal]
This signal gets emitted when an item is renamed via in-place renaming.
Parameters:
| item | is the renamed item. |
| str | is the new value of column col.
|
| col | is the renamed column. |
| void itemRenamed (QListViewItem* item)
| itemRenamed |
[signal]
Same as above, but without the extra information.
| void menuShortCutPressed (KListView* list, QListViewItem* item)
| menuShortCutPressed |
[signal]
This signal is emitted when the shortcut key for popup-menus is pressed.
Normally you should not use this, just connect a slot to signal contextMenu (KListView*, QListViewItem*, const QPoint&) to correctly handle showing context menus regardless of settings.
Parameters:
| list | is this listview. |
| item | is the currentItem() at the time the key was pressed. May be 0L. |
| void contextMenu (KListView* l, QListViewItem* i, const QPoint& p)
| contextMenu |
[signal]
This signal is emitted whenever a context-menu should be shown for item i.
It automatically adjusts for all settings involved (Menu key, showMenuOnPress/Click).
Parameters:
| l | is this listview. |
| i | is the item for which the menu should be shown. May be 0L. |
| p | is the point at which the menu should be shown. |
| void rename (QListViewItem *item, int c)
| rename |
[virtual slot]
Rename column c of item.
| void setRenameable (int column, bool yesno=true)
| setRenameable |
[slot]
By default, if you called setItemsRenameable(true), only the first column is renameable. Use this function to enable the feature on other columns.
If you want more intelligent (dynamic) selection, you'll have to derive from KListView, and override rename() and call only call it if you want the item to be renamed.
| void setItemsMovable (bool b)
