will be None
.
The returned TreePath
must be freed with gtk_tree_path_free()
.
Returns
true
if the cursor is set.

, y
), relative to bin_window coordinates.
In contrast to path_at_pos()
, this function also
obtains the cell at the specified position. The returned path should
be freed with gtk_tree_path_free()
.

The TreePath
corresponding
to the icon or None
if no icon exists at that position.
fn pixbuf_column(&self) -> i32

fn is_reorderable(&self) -> bool
fn is_reorderable(&self) -> bool
Retrieves whether the user can reorder the list via drag-and-drop.
See set_reorderable()
.
Returns
true
if the list can be reordered.
fn row_spacing(&self) -> i32
fn row_spacing(&self) -> i32
fn selected_items(&self) -> Vec<TreePath>
fn selected_items(&self) -> Vec<TreePath>
Creates a list of paths of all selected items. Additionally, if you are
planning on modifying the model after calling this function, you may
want to convert the returned list into a list of GtkTreeRowReferences
.
To do this, you can use TreeRowReference::new()
.
To free the return value, use:
⚠️ The following code is in C ⚠️
g_list_free_full (list, (GDestroyNotify) gtk_tree_path_free);
Returns
A GList
containing a TreePath
for each selected row.
fn selection_mode(&self) -> SelectionMode
fn selection_mode(&self) -> SelectionMode
fn text_column(&self) -> i32
fn text_column(&self) -> i32
fn tooltip_column(&self) -> i32
fn tooltip_column(&self) -> i32
Returns the column of self
’s model which is being used for
displaying tooltips on self
’s rows.
Returns
the index of the tooltip column that is currently being used, or -1 if this is disabled.
This function is supposed to be used in a signal::Widget::query-tooltip
signal handler for IconView
. The x
, y
and keyboard_tip
values
which are received in the signal handler, should be passed to this
function without modification.
The return value indicates whether there is an icon view item at the given
coordinates (true
) or not (false
) for mouse tooltips. For keyboard
tooltips the item returned will be the cursor item. When true
, then any of
model
, path
and iter
which have been provided will be set to point to
that row and the corresponding model. x
and y
will always be converted
to be relative to self
’s bin_window if keyboard_tooltip
is false
.
x
the x coordinate (relative to widget coordinates)
y
the y coordinate (relative to widget coordinates)
keyboard_tip
whether this is a keyboard tooltip or not
Returns
whether or not the given tooltip context points to a item
model
a pointer to receive a
TreeModel
or None
path
a pointer to receive a TreePath
or None
iter
Sets start_path
and end_path
to be the first and last visible path.
Note that there may be invisible paths in between.
Both paths should be freed with gtk_tree_path_free()
after use.
Returns
true
, if valid paths were placed in start_path
and end_path
start_path
Return location for start of region,
or None
end_path
Return location for end of region, or None
fn item_activated(&self, path: &TreePath)
fn item_activated(&self, path: &TreePath)
fn path_is_selected(&self, path: &TreePath) -> bool
fn path_is_selected(&self, path: &TreePath) -> bool
Moves the alignments of self
to the position specified by path
.
row_align
determines where the row is placed, and col_align
determines
where column
is placed. Both are expected to be between 0.0 and 1.0.
0.0 means left/top alignment, 1.0 means right/bottom alignment, 0.5 means
center.
If use_align
is false
, then the alignment arguments are ignored, and the
tree does the minimum amount of work to scroll the item onto the screen.
This means that the item will be scrolled to the edge closest to its current
position. If the item is currently visible on the screen, nothing is done.
This function only works if the model is set, and path
is a valid row on
the model. If the model changes before the self
is realized, the
centered path will be modified to reflect this change.
path
The path of the item to move to.
use_align
whether to use alignment arguments, or false
.
row_align
The vertical alignment of the item specified by path
.
col_align
The horizontal alignment of the item specified by path
.

)
fn set_cursor(
&self,
path: &TreePath,
cell: Option<&impl IsA<CellRenderer>>,
start_editing: bool
)
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 item.
If cell
is not None
, then focus is given to the cell specified by
it. Additionally, if start_editing
is true
, then editing should be
started in the specified cell.
This function is often followed by gtk_widget_grab_focus (icon_view)
in order to give keyboard focus to the widget.
Please note that editing can only happen when the widget is realized.
path
A TreePath
cell

to be column
. The pixbuf
column must be of type GDK_TYPE_PIXBUF
column
A column in the currently used model, or -1 to disable
fn set_reorderable(&self, reorderable: bool)
fn set_reorderable(&self, reorderable: bool)
This function is a convenience function to allow you to reorder models that
support the GtkTreeDragSourceIface
and the GtkTreeDragDestIface
. Both
TreeStore
and ListStore
support these. If reorderable
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
row_inserted and row_deleted signals. The reordering is implemented by setting up
the icon view as a drag source and destination. Therefore, drag and
drop can not be used in a reorderable view for any other purpose.
This function does not give you any degree of control over the order – any reordering is allowed. If more control is needed, you should probably handle drag and drop manually.
reorderable
true
, if the list of items can be reordered.
fn set_row_spacing(&self, row_spacing: i32)
fn set_row_spacing(&self, row_spacing: i32)
Sets the ::row-spacing property which specifies the space which is inserted between the rows of the icon view.

spacing
the spacing
fn set_text_column(&self, column: i32)
fn set_text_column(&self, column: i32)
Sets the column with text for self
to be column
. The text
column must be of type G_TYPE_STRING
.
column
A column in the currently used model, or -1 to display no text
fn set_tooltip_cell(
&self,
tooltip: &Tooltip,
path: &TreePath,
cell: Option<&impl IsA<CellRenderer>>
)
fn set_tooltip_cell(
&self,
tooltip: &Tooltip,
path: &TreePath,
cell: Option<&impl IsA<CellRenderer>>
)
Sets the tip area of tooltip
to the area which cell
occupies in
the item pointed to by path
. See also Tooltip::set_tip_area()
.
See also set_tooltip_column()
for a simpler alternative.
tooltip

path
a TreePath
cell
a CellRenderer
or None
fn set_tooltip_column(&self, column: i32)
fn set_tooltip_column(&self, column: i32)
If you only plan to have simple (text-only) tooltips on full items, you
can use this function to have IconView
handle these automatically
for you. column
should be set to the column in self
’s model
containing the tooltip texts, or -1 to disable this feature.
When enabled, property::Widget::has-tooltip
will be set to true
and
self
will connect a signal::Widget::query-tooltip
signal handler.
Note that the signal handler sets the text with Tooltip::set_markup()
,
so &, <, etc have to be escaped in the text.
column

a CellAreaBox
will be used.
fn connect_activate_cursor_item<F: Fn(&Self) -> bool + 'static>(
&self,
f: F
) -> SignalHandlerId
fn connect_activate_cursor_item<F: Fn(&Self) -> bool + 'static>(
&self,
f: F
) -> SignalHandlerId
A [keybinding signal][GtkBindingSignal] which gets emitted when the user activates the currently focused item.
Applications should not connect to it, but may emit it with
g_signal_emit_by_name()
if they need to control activation
programmatically.
The default bindings for this signal are Space, Return and Enter.
fn emit_activate_cursor_item(&self) -> bool
fn connect_item_activated<F: Fn(&Self, &TreePath) + 'static>(
&self,
f: F
) -> SignalHandlerId
fn connect_item_activated<F: Fn(&Self, &TreePath) + 'static>(
&self,
f: F
) -> SignalHandlerId
The ::item-activated signal is emitted when the method
item_activated()
is called, when the user double
clicks an item with the “activate-on-single-click” property set
to false
, or when the user single clicks an item when the
“activate-on-single-click” property set to true
. It is also
emitted when a non-editable item is selected and one of the keys:
Space, Return or Enter is pressed.

&self,
f: F
) -> SignalHandlerId
The ::move-cursor signal is a [keybinding signal][GtkBindingSignal] which gets emitted when the user initiates a cursor movement.
Applications should not connect to it, but may emit it with
g_signal_emit_by_name()
if they need to control the cursor
programmatically.
The default bindings for this signal include
- Arrow keys which move by individual steps
- Home/End keys which move to the first/last item
- PageUp/PageDown which move by “pages” All of these will extend the selection when combined with the Shift modifier.

fn connect_select_cursor_item<F: Fn(&Self) + 'static>(
&self,
f: F
) -> SignalHandlerId
A [keybinding signal][GtkBindingSignal] which gets emitted when the user selects the item that is currently focused.
Applications should not connect to it, but may emit it with
g_signal_emit_by_name()
if they need to control selection
programmatically.
There is no default binding for this signal.
