Description

GtkScrolledWindow is a container that accepts a single child widget, makes that child scrollable 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. GtkScrolledWindow’s implementation of containerAdd intelligently accounts for whether or not the added child is a Scrollable. If it isn’t, ScrolledWindow wraps the child in a Viewport and adds that for you. Therefore, you can just add any child widget and not worry about the details.

If containerAdd has added a Viewport for you, you can remove both your added child widget from the Viewport, and the Viewport from the GtkScrolledWindow, like this:

C code

GtkWidget *scrolled_window = gtk_scrolled_window_new (NULL, NULL);
GtkWidget *child_widget = gtk_button_new ();

// GtkButton is not a GtkScrollable, so GtkScrolledWindow will automatically
// add a GtkViewport.
gtk_container_add (GTK_CONTAINER (scrolled_window),
                   child_widget);

// Either of these will result in child_widget being unparented:
gtk_container_remove (GTK_CONTAINER (scrolled_window),
                      child_widget);
// or
gtk_container_remove (GTK_CONTAINER (scrolled_window),
                      gtk_bin_get_child (GTK_BIN (scrolled_window)));

Unless ScrolledWindow:policy is GTK_POLICY_NEVER or GTK_POLICY_EXTERNAL, GtkScrolledWindow adds internal Scrollbar widgets around its child. The scroll position of the child, and if applicable the scrollbars, is controlled by the ScrolledWindow:hadjustment and ScrolledWindow:vadjustment that are associated with the GtkScrolledWindow. 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 GtkScrolledWindow 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

GtkScrolledWindow 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 ScrolledWindow:kinetic-scrolling property if it is undesired.

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

If no mouse device is present, the scrollbars will overlayed 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 ScrolledWindow:overlay-scrolling property.

CSS nodes

GtkScrolledWindow has a main CSS node with name scrolledwindow.

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.

GtkScrolledWindow 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.

Methods

addWithViewport

scrolledWindowAddWithViewport Source #

Arguments

:: (HasCallStack, MonadIO m, IsScrolledWindow a, IsWidget b)
=> a	`scrolledWindow`: a `ScrolledWindow`
-> b	`child`: the widget you want to scroll
-> m ()

Deprecated: (Since version 3.8)containerAdd will automatically adda Viewport if the child doesn’t implement Scrollable.

Used to add children without native scrolling capabilities. This is simply a convenience function; it is equivalent to adding the unscrollable child to a viewport, then adding the viewport to the scrolled window. If a child has native scrolling, use containerAdd instead of this function.

The viewport scrolls the child by moving its Window, and takes the size of the child to be the size of its toplevel Window. This will be very wrong for most widgets that support native scrolling; for example, if you add a widget such as TreeView with a viewport, the whole widget will scroll, including the column headings. Thus, widgets with native scrolling support should not be used with the Viewport proxy.

A widget supports scrolling natively if it implements the Scrollable interface.

new

scrolledWindowNew Source #

Arguments

=> Maybe a	`hadjustment`: horizontal adjustment
-> Maybe b	`vadjustment`: vertical adjustment
-> m ScrolledWindow	Returns: a new scrolled window

Creates a new scrolled window.

The two arguments are the scrolled window’s adjustments; these will be shared with the scrollbars and the child widget to keep the bars in sync with the child. Usually you want to pass Nothing for the adjustments, which will cause the scrolled window to create them for you.

Changes the behaviour of scrolledWindow with regard to the initial event that possibly starts kinetic scrolling. When captureButtonPress is set to True, the event is captured by the scrolled window, and then later replayed if it is meant to go to the child widget.

This should be enabled if any child widgets perform non-reversible actions on Widget::button-press-event. If they don't, and handle additionally handle Widget::grab-broken-event, it might be better to set captureButtonPress to False.

This setting only has an effect if kinetic scrolling is enabled.

:: (HasCallStack, MonadIO m, IsScrolledWindow a)
=> a	`scrolledWindow`: a `ScrolledWindow`
-> Int32	`height`: the maximum content height
-> m ()

Sets the maximum height that scrolledWindow should keep visible. The scrolledWindow will grow up to this height before it starts scrolling the content.

scrolledWindowSetPlacement Source #

Arguments

:: (HasCallStack, MonadIO m, IsScrolledWindow a)
=> a	`scrolledWindow`: a `ScrolledWindow`
-> CornerType	`windowPlacement`: position of the child window
-> m ()

Sets the placement of the contents with respect to the scrollbars for the scrolled window.

The default is CornerTypeTopLeft, meaning the child is in the top left, with the scrollbars underneath and to the right. Other values in CornerType are CornerTypeTopRight, CornerTypeBottomLeft, and CornerTypeBottomRight.

setPolicy

-> m ()

Sets the scrollbar policy for the horizontal and vertical scrollbars.

The policy determines when the scrollbar should appear; it is a value from the PolicyType enumeration. If PolicyTypeAlways, the scrollbar is always present; if PolicyTypeNever, the scrollbar is never present; if PolicyTypeAutomatic, the scrollbar is present only if needed (that is, if the slider part of the bar would be smaller than the trough — the display is larger than the page size).

Signals

edgeOvershot

type C_ScrolledWindowEdgeOvershotCallback = Ptr () -> CUInt -> Ptr () -> IO () Source #

Type for the callback on the (unwrapped) C side.

type ScrolledWindowEdgeOvershotCallback Source #

Arguments

= PositionType	`pos`: edge side that was hit
-> IO ()

The ::edge-overshot signal is emitted whenever user initiated scrolling makes the scrolledwindow firmly surpass (ie. with some edge resistance) the lower or upper limits defined by the adjustment in that orientation.

A similar behavior without edge resistance is provided by the ScrolledWindow::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.
