## Detailed Description

Information for presenting toplevels.

Toplevel surfaces are sovereign windows that can be presented to the user in various states (maximized, on all workspaces, etc).

The Gdk::ToplevelLayout class contains information that is necessary to do so, and is passed to Gdk::Toplevel::present().

Since gtkmm 3.98

## Member Function Documentation

## ◆ copy()

Glib::RefPtr< ToplevelLayout > Gdk::ToplevelLayout::copy | ( |  | ) | const

Create a new Gdk::ToplevelLayout and copy the contents of layout into it.

Returns
  A copy of layout.

## ◆ create()

Glib::RefPtr< ToplevelLayout > Gdk::ToplevelLayout::create | ( |  | ) |
| static

Create a toplevel layout description.

Used together with present() to describe how a toplevel surface should be placed and behave on-screen.

The size is in ”application pixels”, not ”device pixels” (see Gdk::Surface::get_scale()).

Returns
  Newly created instance of Gdk::ToplevelLayout.

## ◆ equal()

bool Gdk::ToplevelLayout::equal | ( | const Glib::RefPtr< const ToplevelLayout > & | other | ) | const

Check whether layout and other has identical layout properties.

Parameters

  other | Another toplevel layout.

Returns
  True if layout and other have identical layout properties, otherwise false.

## ◆ get_fullscreen()

bool Gdk::ToplevelLayout::get_fullscreen | ( | bool & | fullscreen | ) | const

If the layout specifies whether to the toplevel should go fullscreen, the value pointed to by fullscreen is set to true if it should go fullscreen, or false, if it should go unfullscreen.

Parameters

  fullscreen | Location to store whether the toplevel should be fullscreen.

Returns
  Whether the layout specifies the fullscreen state for the toplevel.

## ◆ get_fullscreen_monitor() [1/2]

Glib::RefPtr< Monitor > Gdk::ToplevelLayout::get_fullscreen_monitor | ( |  | ) |

Returns the monitor that the layout is fullscreening the surface on.

Returns
  The monitor on which layout fullscreens.

## ◆ get_fullscreen_monitor() [2/2]

Glib::RefPtr< const Monitor > Gdk::ToplevelLayout::get_fullscreen_monitor | ( |  | ) | const

Returns the monitor that the layout is fullscreening the surface on.

Returns
  The monitor on which layout fullscreens.

## ◆ get_maximized()

bool Gdk::ToplevelLayout::get_maximized | ( | bool & | maximized | ) | const

If the layout specifies whether to the toplevel should go maximized, the value pointed to by maximized is set to true if it should go maximized, or false, if it should go unmaximized.

Parameters

  maximized | Set to true if the toplevel should be maximized.

Returns
  Whether the layout specifies the maximized state for the toplevel.

## ◆ get_resizable()

bool Gdk::ToplevelLayout::get_resizable | ( |  | ) | const

Returns whether the layout should allow the user to resize the surface.

Returns
  True if the layout is resizable.

## ◆ gobj() [1/2]

GdkToplevelLayout * Gdk::ToplevelLayout::gobj | ( |  | ) |

Provides access to the underlying C instance.

## ◆ gobj() [2/2]

const GdkToplevelLayout * Gdk::ToplevelLayout::gobj | ( |  | ) | const

Provides access to the underlying C instance.

## ◆ gobj_copy()

GdkToplevelLayout * Gdk::ToplevelLayout::gobj_copy | ( |  | ) | const

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

## ◆ operator delete()

void Gdk::ToplevelLayout::operator delete | ( | void * | ,
|  | std::size_t | )
| protected

## ◆ operator=()

ToplevelLayout & Gdk::ToplevelLayout::operator= | ( | const ToplevelLayout & |  | ) |
| delete

## ◆ reference()

void Gdk::ToplevelLayout::reference | ( |  | ) | const

Increment the reference count for this object.

You should never need to do this manually - use the object via a RefPtr instead.

## ◆ set_fullscreen()

void Gdk::ToplevelLayout::set_fullscreen | ( | bool | fullscreen = true,
|  | const Glib::RefPtr< Monitor > & | monitor = {} )

Sets whether the layout should cause the surface to be fullscreen when presented.

Parameters

  fullscreen | True to fullscreen the surface.
  monitor | The monitor to fullscreen on.

## ◆ set_maximized()

void Gdk::ToplevelLayout::set_maximized | ( | bool | maximized = true | ) |

Sets whether the layout should cause the surface to be maximized when presented.

Parameters

  maximized | True to maximize.

## ◆ set_resizable()

void Gdk::ToplevelLayout::set_resizable | ( | bool | resizable = true | ) |

Sets whether the layout should allow the user to resize the surface after it has been presented.

Parameters

  resizable | True to allow resizing.

## ◆ unreference()

void Gdk::ToplevelLayout::unreference | ( |  | ) | const

Decrement the reference count for this object.

You should never need to do this manually - use the object via a RefPtr instead.

## Friends And Related Symbol Documentation

## ◆ wrap()

Glib::RefPtr< Gdk::ToplevelLayout > wrap | ( | GdkToplevelLayout * | object,
|  | bool | take_copy = false )
| related

A Glib::wrap() method for this object.

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.

Returns
  A C++ instance that wraps this C instance.
