pub struct Flap { /* private fields */ }
Expand description
See the migration guide An adaptive container acting like a box or an overlay.


The Flap
widget can display its children like a Gtk::Box
does or
like a Gtk::Overlay
does, according to the
fold-policy
value.
Flap
has at most three children: content
,
flap
and separator
. Content is the primary
child, flap is displayed next to it when unfolded, or overlays it when
folded. Flap can be shown or hidden by changing the
reveal-flap
value, as well as via swipe gestures if
swipe-to-open
and/or swipe-to-close
are set
to TRUE
.
Optionally, a separator can be provided, which would be displayed between the content and the flap when there’s no shadow to separate them, depending on the transition type.
flap
is transparent by default; add the
.background
style class to it if this is
unwanted.
If modal
is set to TRUE
, content becomes completely
inaccessible when the flap is revealed while folded.
The position of the flap and separator children relative to the content is
determined by orientation, as well as the flap-position
value.
Folding the flap will automatically hide the flap widget, and unfolding it
will automatically reveal it. If this behavior is not desired, the
locked
property can be used to override it.
Common use cases include sidebars, header bars that need to be able to overlap the window content (for example, in fullscreen mode) and bottom sheets.
§AdwFlap as GtkBuildable
The Flap
implementation of the gtk::Buildable
interface supports
setting the flap child by specifying “flap” as the “type” attribute of a
<child>
element, and separator by specifying “separator”. Specifying
“content” child type or omitting it results in setting the content child.
§CSS nodes
Flap
has a single CSS node with name flap
. The node will get the style
classes .folded
when it is folded, and .unfolded
when it’s not.
§Properties
§content
The content widget.
It’s always displayed when unfolded, and partially visible when folded.
Readable | Writeable
§flap
The flap widget.
It’s only visible when reveal-progress
is greater than 0.
Readable | Writeable
§flap-position
The flap position.
If it’s set to GTK_PACK_START
, the flap is displayed before the content,
if GTK_PACK_END
, it’s displayed after the content.
Readable | Writeable
§fold-duration
The fold transition animation duration, in milliseconds.
Readable | Writeable
§fold-policy
The fold policy for the flap.
Readable | Writeable
§fold-threshold-policy
Determines when the flap will fold.
If set to ADW_FOLD_THRESHOLD_POLICY_MINIMUM
, flap will only fold when
the children cannot fit anymore. With ADW_FOLD_THRESHOLD_POLICY_NATURAL
,
it will fold as soon as children don’t get their natural size.
This can be useful if you have a long ellipsizing label and want to let it ellipsize instead of immediately folding.
Readable | Writeable
§folded
Whether the flap is currently folded.
See fold-policy
.
Readable
§locked
Whether the flap is locked.
If FALSE
, folding when the flap is revealed automatically closes it, and
unfolding it when the flap is not revealed opens it. If TRUE
,
reveal-flap
value never changes on its own.
Readable | Writeable
§modal
Whether the flap is modal.
If TRUE
, clicking the content widget while flap is revealed, as well as
pressing the Esc key, will close the flap. If FALSE
, clicks
are passed through to the content widget.
Readable | Writeable
§reveal-flap
Whether the flap widget is revealed.
Readable | Writeable
§reveal-params
The reveal animation spring parameters.
The default value is equivalent to:
⚠️ The following code is in c ⚠️
adw_spring_params_new (1, 0.5, 500)
Readable | Writeable
§reveal-progress
The current reveal transition progress.
0 means fully hidden, 1 means fully revealed.
See reveal-flap
.
Readable
§separator
The separator widget.
It’s displayed between content and flap when there’s no shadow to display.
When exactly it’s visible depends on the transition-type
value.
Readable | Writeable
§swipe-to-close
Whether the flap can be closed with a swipe gesture.
The area that can be swiped depends on the transition-type
value.
Readable | Writeable
§swipe-to-open
Whether the flap can be opened with a swipe gesture.
The area that can be swiped depends on the transition-type
value.
Readable | Writeable
§transition-type
the type of animation used for reveal and fold transitions.
flap
is transparent by default, which means the content
will be seen through it with ADW_FLAP_TRANSITION_TYPE_OVER
transitions;
add the .background
style class to it if
this is unwanted.
