## Detailed Description

Infinite scrollable area containing child widgets and/or custom drawing.

Gtk::Layout is similar to Gtk::DrawingArea in that it's a "blank slate" and doesn't do anything but paint a blank background by default. It's different in that it supports scrolling natively (You can add it directly to a Gtk::ScrolledWindow), and it can contain child widgets, since it's a Gtk::Container. However if you're just going to draw, a Gtk::DrawingArea is a better choice since it has lower overhead.

## Member Function Documentation

Glib::RefPtr<Gdk::Window> Gtk::Layout::get_bin_window | ( |  | ) |

Retrieve the bin window of the layout used for drawing operations.

Since gtkmm 2.14:

Returns:
  A Gdk::Window.

Glib::RefPtr<const Gdk::Window> Gtk::Layout::get_bin_window | ( |  | ) | const

Retrieve the bin window of the layout used for drawing operations.

Since gtkmm 2.14:

Returns:
  A Gdk::Window.

void Gtk::Layout::get_size | ( | guint & | width,
|  | guint & | height
| ) |  | const

Gets the size that has been set on the layout, and that determines the total extents of the layout's scrollbar area.

See set_size().

Parameters:

  width | Location to store the width set on layout, or `0`.
  height | Location to store the height set on layout, or `0`.

const GtkLayout* Gtk::Layout::gobj | ( |  | ) | const`[inline]`

Provides access to the underlying C GtkObject.

Reimplemented from Gtk::Container.

GtkLayout* Gtk::Layout::gobj | ( |  | ) | `[inline]`

Provides access to the underlying C GtkObject.

Reimplemented from Gtk::Container.

void Gtk::Layout::move | ( | Widget& | child_widget,
|  | int | x,
|  | int | y
| ) |  |

Moves a current child of layout to a new position.

Parameters:

  child_widget | A current child of layout.
  x | X position to move to.
  y | Y position to move to.

Glib::PropertyProxy_ReadOnly<guint> Gtk::Layout::property_height | ( |  | ) | const

The height of the layout.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy<guint> Gtk::Layout::property_height | ( |  | ) |

The height of the layout.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy_ReadOnly<guint> Gtk::Layout::property_width | ( |  | ) | const

The width of the layout.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

Glib::PropertyProxy<guint> Gtk::Layout::property_width | ( |  | ) |

The width of the layout.

You rarely need to use properties because there are get_ and set_ methods for almost all of them.

Returns:
  A PropertyProxy that allows you to get or set the property of the value, or receive notification when the value of the property changes.

void Gtk::Layout::put | ( | Widget& | child_widget,
|  | int | x,
|  | int | y
| ) |  |

Adds child_widget to layout, at position ( x, y).

layout becomes the new parent container of child_widget.

Parameters:

  child_widget | Child widget.
  x | X position of child widget.
  y | Y position of child widget.

void Gtk::Layout::set_size | ( | guint | width,
|  | guint | height
| ) |  |

Sets the size of the scrollable area of the layout.

Parameters:

  width | Width of entire scrollable area.
  height | Height of entire scrollable area.

Parameters:

  object | The C instance.
  take_copy | False if the result should take ownership of the C instance. True if it should take a new copy or ref.
