## Detailed Description

Adds scrollbars to its child widget.

This container accepts a single child widget. It adds scrollbars to the child widget and optionally draws a beveled frame around the child widget. The scrolled window can work in two ways: 1) Some widgets have native scrolling support; these widgets handle certain Gtk::Adjustment signals. Widgets with native scroll support include Gtk::TreeView, Gtk::TextView, and Gtk::Layout. 2) For widgets that lack native scrolling support, such as Gtk::Table, Gtk::Box, and so on, the widget will be placed inside a Gtk::Viewport.

The position of the scrollbars is controlled by the scroll adjustments. See Gtk::Adjustment for the fields in an adjustment - for Gtk::Scrollbar, used by Gtk::ScrolledWindow, the "value" field represents the position of the scrollbar, which must be between the "lower" field and "upper - page_size." The "page_size" field represents the size of the visible scrollable area. The "step_increment" and "page_increment" fields are used when the user asks to step down (using the small stepper arrows) or page down (using for example the PageDown key).

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::Table.

void Gtk::ScrolledWindow::set_hadjustment | ( | Gtk::Adjustment& | hadjustment | ) |

Sets the Gtk::Adjustment for the horizontal scrollbar.

Parameters:

Sets the Gtk::Adjustment for the horizontal scrollbar.

Parameters:

  hadjustment | Horizontal scroll adjustment.

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::CORNER_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::CORNER_TOP_RIGHT, Gtk::CORNER_BOTTOM_LEFT, and Gtk::CORNER_BOTTOM_RIGHT.

See also get_placement() and unset_placement().

Parameters:

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::POLICY_ALWAYS, the scrollbar is always present; if Gtk::POLICY_NEVER, the scrollbar is never present; if Gtk::POLICY_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).

Parameters:

  hscrollbar_policy | Policy for horizontal bar.
  vscrollbar_policy | Policy for vertical bar.

void Gtk::ScrolledWindow::set_shadow_type | ( | ShadowType | type | ) |

Changes the type of shadow drawn around the contents of scrolled_window.

Parameters:

  type | Kind of shadow to draw around scrolled window contents.

void Gtk::ScrolledWindow::set_vadjustment | ( | Gtk::Adjustment* | vadjustment = `0` | ) |

Sets the Gtk::Adjustment for the vertical scrollbar.

Parameters:

  vadjustment | Vertical scroll adjustment.

void Gtk::ScrolledWindow::set_vadjustment | ( | Gtk::Adjustment& | vadjustment | ) |

Sets the Gtk::Adjustment for the vertical scrollbar.

Parameters:

  vadjustment | Vertical scroll adjustment.

void Gtk::ScrolledWindow::unset_placement | ( |  | ) |

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

If no window placement is set for a scrolled window, it obeys the "gtk-scrolled-window-placement" XSETTING.

See also set_placement() and get_placement().

Since gtkmm 2.10:
