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 Gtk::Scrollable interface, are added directly. For other types of widget, the class Gtk::Viewport acts as an adaptor, giving scrollability to other widgets. set_child() intelligently accounts for whether or not the added child is a Gtk::Scrollable. If it isn’t, then it wraps the child in a Gtk::Viewport. Therefore, you can just add any child widget and not worry about the details. If set_child() has added a Gtk::Viewport for you, it will be automatically removed when you unset the child.
Unless property_hscrollbar_policy() and property_vscrollbar_policy() are Gtk::PolicyType::NEVER or Gtk::PolicyType::EXTERNAL, Gtk::ScrolledWindow adds internal Gtk::Scrollbar widgets around its child. The scroll position of the child, and if applicable the scrollbars, is controlled by the property_hadjustment() and property_vadjustment() that are associated with the Gtk::ScrolledWindow. See the docs on Gtk::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 Gtk::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 Gtk::Scrollbar and for example a Gtk::Grid.
Gtk::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 property_kinetic_scrolling() if it is undesired.
Gtk::ScrolledWindow also displays visual 'overshoot' indication when the content is pulled beyond the end, and this situation can be captured with signal_edge_overshot().
If no mouse device is present, the scrollbars will be overlaid as narrow, auto-hiding indicators over the content. If traditional scrollbars are desired although no mouse is present, this behavior can be turned off with property_overlay_scrolling().

This is useful in cases where an attempt should be made to allocate exactly enough space for the natural size of the child.
Default value: false
Glib::PropertyProxy_ReadOnly< bool > Gtk::ScrolledWindow::property_propagate_natural_width | ( | ) | const |
Whether the natural width of the child should be calculated and propagated through the scrolled window’s requested natural width.
This is useful in cases where an attempt should be made to allocate exactly enough space for the natural size of the child.
Default value: false
Glib::PropertyProxy< Glib::RefPtr< Adjustment > > Gtk::ScrolledWindow::property_vadjustment | ( | ) |
The Gtk::Adjustment
for the vertical position.
Glib::PropertyProxy_ReadOnly< Glib::RefPtr< Adjustment > > Gtk::ScrolledWindow::property_vadjustment | ( | ) | const |
The Gtk::Adjustment
for the vertical position.
Glib::PropertyProxy< PolicyType > Gtk::ScrolledWindow::property_vscrollbar_policy | ( | ) |
When the vertical scrollbar is displayed.
Use Gtk::ScrolledWindow::set_policy() to set this property.
Default value: Gtk::PolicyType::AUTOMATIC
Glib::PropertyProxy_ReadOnly< PolicyType > Gtk::ScrolledWindow::property_vscrollbar_policy | ( | ) | const |
When the vertical scrollbar is displayed.
Use Gtk::ScrolledWindow::set_policy() to set this property.
Default value: Gtk::PolicyType::AUTOMATIC
Glib::PropertyProxy< CornerType > Gtk::ScrolledWindow::property_window_placement | ( | ) |
Where the contents are located with respect to the scrollbars.
Default value: Gtk::CornerType::TOP_LEFT
Glib::PropertyProxy_ReadOnly< CornerType > Gtk::ScrolledWindow::property_window_placement | ( | ) | const |
Where the contents are located with respect to the scrollbars.
Default value: Gtk::CornerType::TOP_LEFT
Sets the child widget of scrolled_window.
If child does not implement the Gtk::Scrollable interface, the scrolled window will add child to a Gtk::Viewport instance and then add the viewport as its child widget.
child | The child widget. |
void Gtk::ScrolledWindow::set_hadjustment | ( | const Glib::RefPtr< Adjustment > & | hadjustment | ) |
Sets the Gtk::Adjustment
for the horizontal scrollbar.
hadjustment | The Gtk::Adjustment to use, or nullptr to create a new one. |
Changes the frame drawn around the contents of scrolled_window.
has_frame | Whether to draw a frame around scrolled window contents. |
Turns kinetic scrolling on or off.
Kinetic scrolling only applies to devices with source Gdk::InputSource::TOUCHSCREEN.
kinetic_scrolling | true to enable kinetic scrolling. |
void Gtk::ScrolledWindow::set_max_content_height | ( | int | height | ) |
Sets the maximum height that scrolled_window should keep visible.
The scrolled_window will grow up to this height before it starts scrolling the content.
It is a programming error to set the maximum content height to a value smaller than property_min_content_height().
height | The maximum content height. |
void Gtk::ScrolledWindow::set_max_content_width | ( | int | width | ) |
Sets the maximum width that scrolled_window should keep visible.
The scrolled_window will grow up to this width before it starts scrolling the content.
It is a programming error to set the maximum content width to a value smaller than property_min_content_width().
width | The maximum content width. |
void Gtk::ScrolledWindow::set_min_content_height | ( | int | height | ) |
Sets the minimum height that scrolled_window should keep visible.
Note that this can and (usually will) be smaller than the minimum size of the content.
It is a programming error to set the minimum content height to a value greater than property_max_content_height().
height | The minimal content height. |
void Gtk::ScrolledWindow::set_min_content_width | ( | int | width | ) |
Sets the minimum width that scrolled_window should keep visible.
Note that this can and (usually will) be smaller than the minimum size of the content.
It is a programming error to set the minimum content width to a value greater than property_max_content_width().
width | The minimal content width. |
Enables or disables overlay scrolling for this scrolled window.
overlay_scrolling | Whether to enable overlay scrolling. |
void Gtk::ScrolledWindow::set_placement | ( | CornerType | window_placement | ) |
Sets the placement of the contents with respect to the scrollbars for the scrolled window.
The default is Gtk::CornerType::TOP_LEFT, meaning the child is in the top left, with the scrollbars underneath and to the right. Other values in Gtk::CornerType are Gtk::CornerType::TOP_RIGHT, Gtk::CornerType::BOTTOM_LEFT, and Gtk::CornerType::BOTTOM_RIGHT.
See also get_placement() and unset_placement().
window_placement | Position of the child window. |
void Gtk::ScrolledWindow::set_policy | ( | PolicyType | hscrollbar_policy, |
PolicyType | vscrollbar_policy | ||
) |
Sets the scrollbar policy for the horizontal and vertical scrollbars.
The policy determines when the scrollbar should appear; it is a value from the Gtk::PolicyType enumeration. If Gtk::PolicyType::ALWAYS, the scrollbar is always present; if Gtk::PolicyType::NEVER, the scrollbar is never present; if Gtk::PolicyType::AUTOMATIC, 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).
hscrollbar_policy | Policy for horizontal bar. |
vscrollbar_policy | Policy for vertical bar. |
Sets whether the natural height of the child should be calculated and propagated through the scrolled window’s requested natural height.
propagate | Whether to propagate natural height. |
Sets whether the natural width of the child should be calculated and propagated through the scrolled window’s requested natural width.
propagate | Whether to propagate natural width. |
void Gtk::ScrolledWindow::set_vadjustment | ( | const Glib::RefPtr< Adjustment > & | vadjustment | ) |
Sets the Gtk::Adjustment
for the vertical scrollbar.
vadjustment | The Gtk::Adjustment to use, or nullptr to create a new one. |
Glib::SignalProxy< void(Gtk::PositionType)> Gtk::ScrolledWindow::signal_edge_overshot | ( | ) |
void on_my_edge_overshot(Gtk::PositionType pos)
Flags: Run Last
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 signal_edge_reached() signal.
pos | Edge side that was hit. |
Glib::SignalProxy< void(Gtk::PositionType)> Gtk::ScrolledWindow::signal_edge_reached | ( | ) |
void on_my_edge_reached(Gtk::PositionType pos)
Flags: Run Last
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 signal_edge_overshot() signal.
pos | Edge side that was reached. |
void Gtk::ScrolledWindow::unset_child | ( | ) |
void Gtk::ScrolledWindow::unset_placement | ( | ) |
Unsets the placement of the contents with respect to the scrollbars.
If no window placement is set for a scrolled window, it defaults to Gtk::CornerType::TOP_LEFT.
