| Description
|
|
Widget that displays any object that implements the TreeModel
interface.
The widget supports scrolling natively. This implies that pixel
coordinates can be given in two formats: relative to the current view's
upper left corner or relative to the whole list's coordinates. The former
are called widget coordinates while the letter are called tree
coordinates.

| Create a new TreeView
widget with model as the storage model.
|
|
| Methods
|
|
| treeViewGetModel :: TreeViewClass self => self -> IO (Maybe TreeModel) |
| Returns the model that supplies the data for
this TreeView. Returns Nothing if the model is unset.
|
|
| treeViewSetModel :: (TreeViewClass self, TreeModelClass model) => self -> model -> IO () |
| Set the TreeModel for the current View.
|
|
| treeViewGetSelection :: TreeViewClass self => self -> IO TreeSelection |
| Retrieve a TreeSelection that
holds the current selected nodes of the View.
|
|
| treeViewGetHAdjustment :: TreeViewClass self => self -> IO (Maybe Adjustment) |
| Gets the Adjustment currently being used for the horizontal aspect.
|
|
| treeViewSetHAdjustment |
|
|
| treeViewGetVAdjustment :: TreeViewClass self => self -> IO (Maybe Adjustment) |
| Gets the Adjustment currently being used for the vertical aspect.
|
|
| treeViewSetVAdjustment |
|
|
| treeViewGetHeadersVisible :: TreeViewClass self => self -> IO Bool |
| Query if the column headers are visible.
|
|
| treeViewSetHeadersVisible :: TreeViewClass self => self -> Bool -> IO () |
| Set the visibility state of the column headers.
|
|
| treeViewColumnsAutosize :: TreeViewClass self => self -> IO () |
| Resize the columns to their optimal size.
|
|
| treeViewSetHeadersClickable :: TreeViewClass self => self -> Bool -> IO () |
| Set wether the columns headers are sensitive to mouse clicks.
|
|
| treeViewGetRulesHint :: TreeViewClass self => self -> IO Bool |
| Query if visual aid for wide columns is turned on.
|
|
| treeViewSetRulesHint :: TreeViewClass self => self -> Bool -> IO () |
| This function tells Gtk+ that the user interface for your application
requires users to read across tree rows and associate cells with one
another. By default, Gtk+ will then render the tree with alternating row
colors. Do not use it just because you prefer the appearance of the ruled
tree; that's a question for the theme. Some themes will draw tree rows in
alternating colors even when rules are turned off, and users who prefer that
appearance all the time can choose those themes. You should call this
function only as a semantic hint to the theme engine that your tree makes
alternating colors useful from a functional standpoint (since it has lots of
columns, generally).
|
|
| treeViewAppendColumn :: TreeViewClass self => self -> TreeViewColumn -> IO Int |
| Append a new column to the TreeView. Returns the new number of columns.
|
|
| treeViewRemoveColumn :: TreeViewClass self => self -> TreeViewColumn -> IO Int |
| Remove column tvc from the TreeView
widget. The number of remaining columns is returned.
|
|
| treeViewInsertColumn :: TreeViewClass self => self -> TreeViewColumn -> Int -> IO Int |
| Inserts column tvc into the
TreeView widget at the position pos. Returns the number of
columns after insertion. Specify -1 for pos to insert the column
at the end.
|
|
| treeViewGetColumn :: TreeViewClass self => self -> Int -> IO (Maybe TreeViewColumn) |
Retrieve a TreeViewColumn.
- Retrieve the pos th columns of
TreeView. If the index is out of range Nothing is returned.
|
|
| treeViewGetColumns :: TreeViewClass self => self -> IO [TreeViewColumn] |
| Return all TreeViewColumns in this TreeView.
|
|
| treeViewMoveColumnAfter :: TreeViewClass self => self -> TreeViewColumn -> TreeViewColumn -> IO () |
Move a specific column.
- Use treeViewMoveColumnToFront if you want to move the column
to the left end of the TreeView.
|
|
| treeViewMoveColumnFirst :: TreeViewClass self => self -> TreeViewColumn -> IO () |
Move a specific column.
|
|
| treeViewSetExpanderColumn :: TreeViewClass self => self -> Maybe TreeViewColumn -> IO () |
Set location of hierarchy controls.
- Sets the column to draw the expander arrow at. If col
is Nothing, then the expander arrow is always at the first
visible column.
If you do not want expander arrow to appear in your tree, set the
expander column to a hidden column.
|
|
| treeViewGetExpanderColumn :: TreeViewClass self => self -> IO TreeViewColumn |
Get location of hierarchy controls.
- Gets the column to draw the expander arrow at. If col
is Nothing, then the expander arrow is always at the first
visible column.
|
|
| treeViewSetColumnDragFunction :: TreeViewClass self => self -> Maybe (TreeViewColumn -> Maybe TreeViewColumn -> Maybe TreeViewColumn -> IO Bool) -> IO () |
Specify where a column may be dropped.
- Sets a user function for determining where a column may be dropped when
dragged. This function is called on every column pair in turn at the
beginning of a column drag to determine where a drop can take place.
- The callback function take the TreeViewColumn to be moved, the
second and third arguments are the columns on the left and right side
of the new location. At most one of them might be Nothing
which indicates that the column is about to be dropped at the left or
right end of the TreeView.
- The predicate pred should return True if it is ok
to insert the column at this place.
- Use Nothing for the predicate if columns can be inserted
anywhere.
|
|
| treeViewScrollToPoint :: TreeViewClass self => self -> Int -> Int -> IO () |
Scroll to a coordinate.
- Scrolls the tree view such that the top-left corner of the
visible area is treeX, treeY, where treeX
and treeY are specified in tree window coordinates.
The TreeView must be realized before this function is
called. If it isn't, you probably want to use
treeViewScrollToCell.
|
|
| treeViewScrollToCell :: TreeViewClass self => self -> TreePath -> TreeViewColumn -> Maybe (Float, Float) -> IO () |
Scroll to a cell.
- Scroll to a cell as specified by path and tvc.
The cell is aligned within the TreeView widget as
follows: horizontally by hor from left (0.0) to
right (1.0) and vertically by ver from top
(0.0) to buttom (1.0).
|
|
| treeViewSetCursor :: TreeViewClass self => self -> TreePath -> Maybe (TreeViewColumn, Bool) -> IO () |
Selects a specific row.
- Sets the current keyboard focus to be at path, and
selects it. This is useful when you want to focus the user's
attention on a particular row. If focusColumn is given,
then the input focus is given to the column specified by
it. Additionally, if focusColumn is specified, and
startEditing is True,
then editing will be started in the
specified cell. This function is often followed by a
widgetGrabFocus to the TreeView in order
to give keyboard focus to the widget.
|
|
| treeViewSetCursorOnCell :: (TreeViewClass self, CellRendererClass focusCell) => self -> TreePath -> TreeViewColumn -> focusCell -> Bool -> IO () |
Selects a cell in a specific row.
|
|
| treeViewGetCursor :: TreeViewClass self => self -> IO (TreePath, Maybe TreeViewColumn) |
Retrieves the position of the focus.
- Returns a pair (path, column).If the cursor is not currently
set, path will be []. If no column is currently
selected, column will be Nothing.
|
|
| treeViewRowActivated :: TreeViewClass self => self -> TreePath -> TreeViewColumn -> IO () |
| Emit the activated signal on a cell.
|
|
| treeViewExpandAll :: TreeViewClass self => self -> IO () |
| Recursively expands all nodes in the tree view.
|
|
| treeViewCollapseAll :: TreeViewClass self => self -> IO () |
| Recursively collapses all visible, expanded nodes in the tree view.
|
|
| treeViewExpandToPath :: TreeViewClass self => self -> TreePath -> IO () |
Make a certain path visible.
- This will expand all parent rows of tp as necessary.
- Only available in Gtk 2.2 and higher.
|
|
| treeViewExpandRow |
| :: TreeViewClass self | | | => self | | | -> TreePath | path - path to a row
| | -> Bool | openAll - whether to recursively expand, or just expand
immediate children
| | -> IO Bool | returns True if the row existed and had children
| | Opens the row so its children are visible.
|
|
|
| treeViewCollapseRow |
| :: TreeViewClass self | | | => self | | | -> TreePath | path - path to a row in the tree view
| | -> IO Bool | returns True if the row was collapsed.
| | Collapses a row (hides its child rows, if they exist).
|
|
|
| treeViewMapExpandedRows :: TreeViewClass self => self -> (TreePath -> IO ()) -> IO () |
| Call function for every expaned row.
|
|
| treeViewRowExpanded |
| :: TreeViewClass self | | | => self | | | -> TreePath | path - A TreePath to test expansion state.
| | -> IO Bool | returns True if path is expanded.
| | Check if row is expanded.
|
|
|
| treeViewGetReorderable :: TreeViewClass self => self -> IO Bool |
Query if rows can be moved around.
|
|
| treeViewSetReorderable :: TreeViewClass self => self -> Bool -> IO () |
Check if rows can be moved around.
- Set whether the user can use drag and drop (DND) to reorder the rows in
the store. This works on both TreeStore and ListStore models. If ro
is True, then the user can reorder the model by dragging and dropping
rows. The developer can listen to these changes by connecting to the
model's signals. If you need to control which rows may be dragged or
where rows may be dropped, you can override the
treeDragSourceRowDraggable
function in the default DND implementation of the model.
|
|
| treeViewGetPathAtPos :: TreeViewClass self => self -> Point -> IO (Maybe (TreePath, TreeViewColumn, Point)) |
Map a pixel to the specific cell.
- Finds the path at the Point (x, y). The
coordinates x and y are relative to the top left
corner of the TreeView drawing window. As such, coordinates
in a mouse click event can be used directly to determine the cell
which the user clicked on. This function is useful to realize
popup menus.
- The returned point is the input point relative to the cell's upper
left corner. The whole TreeView is divided between all cells.
The returned point is relative to the rectangle this cell occupies
within the TreeView.
|
|
| treeViewGetCellArea :: TreeViewClass self => self -> Maybe TreePath -> TreeViewColumn -> IO Rectangle |
Retrieve the smallest bounding box of a cell.
- Fills the bounding rectangle in tree window coordinates for the
cell at the row specified by tp and the column specified by
tvc.
If path is Nothing or points to a path not
currently displayed, the y and height fields of
the Rectangle will be filled with 0. The sum of
all cell rectangles does not cover the entire tree; there are extra
pixels in between rows, for example.
|
|
| treeViewGetBackgroundArea :: TreeViewClass self => self -> Maybe TreePath -> TreeViewColumn -> IO Rectangle |
Retrieve the largest bounding box of a cell.
- Fills the bounding rectangle in tree window coordinates for the
cell at the row specified by tp and the column specified by
tvc.
If path is Nothing or points to a path not
currently displayed, the y and height fields of
the Rectangle will be filled with 0. The background
areas tile the widget's area to cover the entire tree window
(except for the area used for header buttons). Contrast this with
treeViewGetCellArea.
|
|
| treeViewGetVisibleRect :: TreeViewClass self => self -> IO Rectangle |
Retrieve the currently visible area.
- The returned rectangle gives the visible part of the tree in tree
coordinates.
|
|
| treeViewWidgetToTreeCoords |
| :: TreeViewClass self | | | => self | | | -> Point | (wx, wy) - widget X and Y coordinates
| | -> IO Point | (tx, ty) returns tree X and Y coordinates
| Convert widget to tree pixel coordinates.
|
|
|
| treeViewTreeToWidgetCoords |
| :: TreeViewClass self | | | => self | | | -> Point | (tx, ty) - tree X and Y coordinates
| | -> IO Point | (wx, wy) returns widget X and Y coordinates
| Convert tree to widget pixel coordinates.
|
|
|
| treeViewCreateRowDragIcon :: TreeViewClass self => self -> TreePath -> IO Pixmap |
| Creates a Pixmap representation of the row at the given path. This image
can be used for a drag icon.
|
|
| treeViewGetEnableSearch :: TreeViewClass self => self -> IO Bool |
Returns whether or not the tree allows to start interactive searching by
typing in text.
- If enabled, the user can type in text which will set the cursor to
the first matching entry.
|
|
| treeViewSetEnableSearch :: TreeViewClass self => self -> Bool -> IO () |
If this is set, then the user can type in text to search
through the tree interactively (this is sometimes called "typeahead
find").
Note that even if this is False, the user can still initiate a search
using the "start-interactive-search" key binding. In any case,
a predicate that compares a row of the model with the text the user
has typed must be set using treeViewSetSearchEqualFunc.
|
|
| treeViewSetSearchEqualFunc :: TreeViewClass self => self -> Maybe (String -> TreeIter -> IO Bool) -> IO () |
Set the predicate to test for equality.
- The predicate must returns True if the text entered by the user
and the row of the model match.
|
|
| treeViewGetFixedHeightMode |
| :: TreeViewClass self | | | => self | | | -> IO Bool | returns True if the tree view is in fixed height mode
| Returns whether fixed height mode is turned on for the tree view.
- Available since Gtk+ version 2.6
|
|
|
| treeViewSetFixedHeightMode |
| :: TreeViewClass self | | | => self | | | -> Bool | enable - True to enable fixed height mode
| | -> IO () | | Enables or disables the fixed height mode of the tree view. Fixed height
mode speeds up TreeView by assuming that all rows have the same height.
Only enable this option if all rows are the same height and all columns are
of type TreeViewColumnFixed.
- Available since Gtk+ version 2.6
|
|
|
| treeViewGetHoverSelection |

selection makes the selected row follow the pointer. Currently, this works
only for the selection modes SelectionSingle and SelectionBrowse.
- Available since Gtk+ version 2.6
|
|
|
| treeViewGetHoverExpand |
| :: TreeViewClass self | | | => self | | | -> IO Bool | returns True if the tree view is in hover expansion mode

- Available since Gtk+ version 2.6
|
|
|
| treeViewSetHoverExpand |
| :: TreeViewClass self | | | => self | | | -> Bool | expand - True to enable hover selection mode
| | -> IO () | | Enables of disables the hover expansion mode of the tree view. Hover
expansion makes rows expand or collaps if the pointer moves over them.
- Available since Gtk+ version 2.6

returned.
- Available since Gtk+ version 2.10
|
|
|
| treeViewSetSearchEntry |
| :: (TreeViewClass self, EntryClass entry) | | | => self | | | -> Maybe entry | entry - the entry the interactive search code of treeView
should use or Nothing
| | -> IO () | | Sets the entry which the interactive search code will use for this
treeView. This is useful when you want to provide a search entry in our
interface at all time at a fixed position. Passing Nothing for entry
will make the interactive search code use the built-in popup entry again.
- Available since Gtk+ version 2.10
|

| Attributes
|
|
| treeViewModel :: (TreeViewClass self, TreeModelClass model) => ReadWriteAttr self (Maybe TreeModel) model |
| The model for the tree view.
|
|
| treeViewHAdjustment :: TreeViewClass self => Attr self (Maybe Adjustment) |
| Horizontal Adjustment for the widget.
|
|
| treeViewVAdjustment :: TreeViewClass self => Attr self (Maybe Adjustment) |
| Vertical Adjustment for the widget.
|
|
| treeViewHeadersVisible :: TreeViewClass self => Attr self Bool |
Show the column header buttons.
Default value: True
|
|
| treeViewHeadersClickable :: TreeViewClass self => Attr self Bool |
Column headers respond to click events.
Default value: False
|
|
| treeViewExpanderColumn :: TreeViewClass self => ReadWriteAttr self TreeViewColumn (Maybe TreeViewColumn) |
| Set the column for the expander column.
|
|
| treeViewReorderable :: TreeViewClass self => Attr self Bool |
View is reorderable.
Default value: False
|
|
| treeViewRulesHint :: TreeViewClass self => Attr self Bool |
Set a hint to the theme engine to draw rows in alternating colors.
Default value: False
|
|
| treeViewEnableSearch :: TreeViewClass self => Attr self Bool |
View allows user to search through columns interactively.
Default value: True
|
|
| treeViewFixedHeightMode :: TreeViewClass self => Attr self Bool |
Setting the fixed-height-mode property to True speeds up TreeView
by assuming that all rows have the same height. Only enable this option if
all rows are the same height. Please see treeViewSetFixedHeightMode for
more information on this option.
Default value: False
|
|
| treeViewHoverSelection :: TreeViewClass self => Attr self Bool |
Enables of disables the hover selection mode of the tree view. Hover
selection makes the selected row follow the pointer. Currently, this works
only for the selection modes SelectionSingle and SelectionBrowse.
This mode is primarily indended for treeviews in popups, e.g. in
ComboBox or EntryCompletion.
Default value: False
|
|
| treeViewHoverExpand :: TreeViewClass self => Attr self Bool |
Enables of disables the hover expansion mode of the tree view. Hover
expansion makes rows expand or collaps if the pointer moves over them.
This mode is primarily indended for treeviews in popups, e.g. in
ComboBox or EntryCompletion.
Default value: False
|
|
| Signals
|
|
| onColumnsChanged :: TreeViewClass self => self -> IO () -> IO (ConnectId self) |
| The user has dragged a column to another position.
|
|
| afterColumnsChanged :: TreeViewClass self => self -> IO () -> IO (ConnectId self) |
|
| onCursorChanged :: TreeViewClass self => self -> IO () -> IO (ConnectId self) |
| The cursor in the tree has moved.
|
|
| afterCursorChanged :: TreeViewClass self => self -> IO () -> IO (ConnectId self) |
|
| onRowActivated :: TreeViewClass self => self -> (TreePath -> TreeViewColumn -> IO ()) -> IO (ConnectId self) |
A row was activated.
- Activation usually means the user has pressed return on a row.
|
|
| afterRowActivated :: TreeViewClass self => self -> (TreePath -> TreeViewColumn -> IO ()) -> IO (ConnectId self) |
|
| onRowCollapsed :: TreeViewClass self => self -> (TreeIter -> TreePath -> IO ()) -> IO (ConnectId self) |
| Children of this node were hidden.
|
|
| afterRowCollapsed :: TreeViewClass self => self -> (TreeIter -> TreePath -> IO ()) -> IO (ConnectId self) |
|
| onRowExpanded :: TreeViewClass self => self -> (TreeIter -> TreePath -> IO ()) -> IO (ConnectId self) |
| Children of this node are made visible.
|
|
| afterRowExpanded :: TreeViewClass self => self -> (TreeIter -> TreePath -> IO ()) -> IO (ConnectId self) |
|
| onStartInteractiveSearch :: TreeViewClass self => self -> IO () -> IO (ConnectId self) |
The user wants to search interactively.
- Connect to this signal if you want to provide you own search facility.
Note that you must handle all keyboard input yourself.
|
|
| afterStartInteractiveSearch :: TreeViewClass self => self -> IO () -> IO (ConnectId self) |
|
| onTestCollapseRow :: TreeViewClass self => self -> (TreeIter -> TreePath -> IO Bool) -> IO (ConnectId self) |
Determine if this row should be collapsed.
- If the application connects to this function and returns False,
the specifc row will not be altered.
|
|
| afterTestCollapseRow :: TreeViewClass self => self -> (TreeIter -> TreePath -> IO Bool) -> IO (ConnectId self) |
|
| onTestExpandRow :: TreeViewClass self => self -> (TreeIter -> TreePath -> IO Bool) -> IO (ConnectId self) |
Determine if this row should be expanded.
- If the application connects to this function and returns False,
the specifc row will not be altered.
|
|
| afterTestExpandRow :: TreeViewClass self => self -> (TreeIter -> TreePath -> IO Bool) -> IO (ConnectId self) |
