Struct gtk4::ScrolledWindow

#[repr(transparent)]
pub struct ScrolledWindow { /* private fields */ }

ScrolledWindow is a container that makes its child scrollable.

It does so using either internally added scrollbars or externally associated adjustments, and optionally draws a frame around the child.

Widgets with native scrolling support, i.e. those whose classes implement the Scrollable interface, are added directly. For other types of widget, the class Viewport acts as an adaptor, giving scrollability to other widgets. set_child() intelligently accounts for whether or not the added child is a Scrollable. If it isn’t, then it wraps the child in a Viewport. Therefore, you can just add any child widget and not worry about the details.

If set_child() has added a Viewport for you, it will be automatically removed when you unset the child. Unless hscrollbar-policy and vscrollbar-policy are PolicyType::Never or PolicyType::External, ScrolledWindow adds internal Scrollbar widgets around its child. The scroll position of the child, and if applicable the scrollbars, is controlled by the hadjustment and vadjustment that are associated with the ScrolledWindow. See the docs on Scrollbar for the details, but note that the “step_increment” and “page_increment” fields are only effective if the policy causes scrollbars to be present.

If a ScrolledWindow doesn’t behave quite as you would like, or doesn’t have exactly the right layout, it’s very possible to set up your own scrolling with Scrollbar and for example a Grid.

Touch support

ScrolledWindow has built-in support for touch devices. When a touchscreen is used, swiping will move the scrolled window, and will expose ‘kinetic’ behavior. This can be turned off with the kinetic-scrolling property if it is undesired.

ScrolledWindow also displays visual ‘overshoot’ indication when the content is pulled beyond the end, and this situation can be captured with the edge-overshot signal.

If no mouse device is present, the scrollbars will overlaid as narrow, auto-hiding indicators over the content. If traditional scrollbars are desired although no mouse is present, this behaviour can be turned off with the overlay-scrolling property.

CSS nodes

ScrolledWindow has a main CSS node with name scrolledwindow. It gets a .frame style class added when has-frame is true.

It uses subnodes with names overshoot and undershoot to draw the overflow and underflow indications. These nodes get the .left, .right, .top or .bottom style class added depending on where the indication is drawn.

ScrolledWindow also sets the positional style classes (.left, .right, .top, .bottom) and style classes related to overlay scrolling (.overlay-indicator, .dragging, .hovering) on its scrollbars.

If both scrollbars are visible, the area where they meet is drawn with a subnode named junction.

Accessibility

ScrolledWindow uses the AccessibleRole::Group role.

Signals

edge-overshot

Emitted whenever user initiated scrolling makes the scrolled window firmly surpass the limits defined by the adjustment in that orientation.

A similar behavior without edge resistance is provided by the edge-reached signal.

Note: The @pos argument is LTR/RTL aware, so callers should be aware too if intending to provide behavior on horizontal edges.

edge-reached

Emitted whenever user-initiated scrolling makes the scrolled window exactly reach the lower or upper limits defined by the adjustment in that orientation.

A similar behavior with edge resistance is provided by the edge-overshot signal.

Note: The @pos argument is LTR/RTL aware, so callers should be aware too if intending to provide behavior on horizontal edges.

move-focus-out

Emitted when focus is moved away from the scrolled window by a keybinding.

This is a keybinding signal.

The default bindings for this signal are Ctrl + Tab to move forward and Ctrl + Shift + Tab to move backward.

Action

scroll-child

Emitted when a keybinding that scrolls is pressed.

This is a keybinding signal.

The horizontal or vertical adjustment is updated which triggers a signal that the scrolled window’s child may listen to and scroll itself.

Action

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.

See WidgetExt::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 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).
