pub struct BottomSheet { /* private fields */ }
v1_6
only.Expand description
A bottom sheet with an optional bottom bar.
BottomSheet
has three child widgets. content
is
shown persistently. sheet
is displayed above it when
it’s open, and bottom-bar
is displayed when it’s not.
Bottom sheet and bottom bar are attached to the bottom edge of the widget.
They take the full width by default, but can only take a portion of it if
full-width
is set to FALSE
. In this case,
align
determines where along the bottom edge they are
placed.
Bottom bar can be hidden using the reveal-bottom-bar
property.
BottomSheet
can be useful for applications such as music players, that
want to have a persistent bottom bar that expands into a bottom sheet when
clicked. It’s meant for cases where a bottom sheet is tightly integrated into
the UI. For more transient bottom sheets, see Dialog
.
To open or close the bottom sheet, use the open
property.
By default, the bottom sheet has an overlaid drag handle. It can be disabled
by setting show-drag-handle
to FALSE
. Note that the
handle also controls whether the sheet can be dragged using a pointer.
Bottom sheets are modal by default, meaning that the content is dimmed and
cannot be accessed while the sheet is open. Set modal
to FALSE
if this behavior is unwanted.
To disable user interactions for opening or closing the bottom sheet (such as
swipes or clicking the bottom bar or close button), set
can-open
or can-close
to
FALSE
.
In some cases, particularly when using a full-width bottom bar, it may be
necessary to shift content
upwards. Use the
bottom-bar-height
and
sheet-height
for that.
BottomSheet
is not adaptive, and for larger window sizes applications
may want to replace it with another UI, such as a sidebar. This can be done
using MultiLayoutView
.
§Sizing
Unlike Dialog
presented as a bottom sheet, BottomSheet
just
follows the content’s natural size, and it’s up to the applications to make
sure their content provides one. For example, when using
gtk::ScrolledWindow
, make sure to set
propagate-natural-height
to TRUE
.
§Header Bar Integration
When placed inside an BottomSheet
, HeaderBar
will not show the
title when show-drag-handle
is TRUE
, regardless of
show-title
. This only applies to the default title,
titles set with title-widget
will still be shown.
§BottomSheet
as gtk::Buildable
:
The BottomSheet
implementation of the gtk::Buildable
interface
supports setting the sheet widget by specifying “sheet” as the “type”
attribute of a <child>
element, and the bottom bar by specifying
“bottom-bar”. Specifying “content” or omitting the child type results in
setting the content child.
§Properties
§align
Horizontal alignment of the bottom sheet.
0 means the bottom sheet is flush with the start edge, 1 means it’s flush with the end edge. 0.5 means it’s centered.
Only used when full-width
is set to FALSE
.
Readable | Writeable
§bottom-bar
The bottom bar widget.

is FALSE
. When open, morphs into
the sheet
.
Bottom bar can be temporarily hidden using the
reveal-bottom-bar
property.
Readable | Writeable
§bottom-bar-height
The current bottom bar height.
It can be used to shift the content upwards permanently to accommodate for the bottom bar.
Readable
§can-close
Whether the bottom sheet can be closed by user.
It can be closed via the close button, swiping down, pressing Escape or clicking the content dimming (when modal).
Bottom sheet can still be closed using open
.

§can-open
Whether the bottom sheet can be opened by user.
It can be opened via clicking or swiping up from the bottom bar.
Does nothing if bottom-bar
is not set.
Bottom sheet can still be opened using open
.
Readable | Writeable
§content

Readable | Writeable
§full-width
Whether the bottom sheet takes the full width.
When full width, align
is ignored.
Readable | Writeable
§modal
Whether the bottom sheet is modal.
When modal, content
will be dimmed when the bottom
sheet is open, and clicking it will close the bottom sheet. It also cannot
be focused with keyboard.
Otherwise, the content is accessible even when the bottom sheet is open.

§Signals
§close-attempt
Emitted when the close button or shortcut is used while
can-close
is set to FALSE
.
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 [WidgetExtManual::keynav_failed()
][crate::gtk::prelude::WidgetExtManual::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.
The ::move-focus signal is a keybinding signal.
The default bindings for this signal are Tab to move forward, and Shift+Tab to move backward.
Action
§query-tooltip
Emitted when the widget’s 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 GdkSurface
.
This means that [WidgetExtManual::realize()
][crate::gtk::prelude::WidgetExtManual::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.
See [WidgetExtManual::state_flags()
][crate::gtk::prelude::WidgetExtManual::state_flags()].
§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 GdkSurface
associated with @widget is destroyed.
This means that [WidgetExtManual::unrealize()
][crate::gtk::prelude::WidgetExtManual::unrealize()] has been called
or the widget has been unmapped (that is, it is going to be hidden).
