#[repr(transparent)]pub struct GridView { /* private fields */ }
Expand description
GridView
presents a large dynamic grid of items.
GridView
uses its factory to generate one child widget for each
visible item and shows them in a grid. The orientation of the grid view
determines if the grid reflows vertically or horizontally.
GridView
allows the user to select items according to the selection
characteristics of the model. For models that allow multiple selected items,
it is possible to turn on rubberband selection, using
enable-rubberband
.
To learn more about the list widget framework, see the overview.

GridView
uses a single CSS node with name gridview
. Each child uses
a single CSS node with name child
. If the activatable
property is set, the corresponding row will have the .activatable
style
class. For rubberband selection, a subnode with name rubberband
is used.
Accessibility
GridView
uses the AccessibleRole::Grid
role, and the items
use the AccessibleRole::GridCell
role.
Properties
enable-rubberband
Allow rubberband selection.

Signals
activate
Emitted when a cell has been activated by the user, usually via activating the GtkGridView|list.activate-item action.
This allows for a convenient way to handle activation in a gridview.
See activatable
for details on how to use
this signal.
Widget
destroy
Signals that all holders of a reference to the widget should release the reference that they hold.
May result in finalization of the widget if all references are released.
This signal is not suitable for saving widget state.
direction-changed
Emitted when the text direction of a widget changes.
hide
Emitted when @widget is hidden.
keynav-failed
Emitted if keyboard navigation fails.
See WidgetExt::keynav_failed()
for details.
map
Emitted when @widget is going to be mapped.
A widget is mapped when the widget is visible (which is controlled with
visible
) and all its parents up to the toplevel widget
are also visible.
The ::map signal can be used to determine whether a widget will be drawn,
for instance it can resume an animation that was stopped during the
emission of unmap
.
mnemonic-activate
Emitted when a widget is activated via a mnemonic.
The default handler for this signal activates @widget if @group_cycling
is false
, or just makes @widget grab focus if @group_cycling is true
.
move-focus
Emitted when the focus is moved.
Action
query-tooltip
Emitted when the widgets tooltip is about to be shown.
This happens when the has-tooltip
property
is true
and the hover timeout has expired with the cursor hovering
“above” @widget; or emitted when @widget got focus in keyboard mode.
Using the given coordinates, the signal handler should determine
whether a tooltip should be shown for @widget. If this is the case
true
should be returned, false
otherwise. Note that if
@keyboard_mode is true
, the values of @x and @y are undefined and
should not be used.
The signal handler is free to manipulate @tooltip with the therefore destined function calls.
realize
Emitted when @widget is associated with a gdk::Surface
.
This means that WidgetExt::realize()
has been called
or the widget has been mapped (that is, it is going to be drawn).
show
Emitted when @widget is shown.
state-flags-changed
Emitted when the widget state changes.
unmap
Emitted when @widget is going to be unmapped.
A widget is unmapped when either it or any of its parents up to the toplevel widget have been set as hidden.
As ::unmap indicates that a widget will not be shown any longer, it can be used to, for example, stop an animation on the widget.
unrealize
Emitted when the gdk::Surface
associated with @widget is destroyed.
This means that WidgetExt::unrealize()
has been called
or the widget has been unmapped (that is, it is going to be hidden).
