Struct gdk4::ToplevelLayout

#[repr(transparent)]
pub struct ToplevelLayout { /* private fields */ }

The ToplevelLayout struct contains information that is necessary to present a sovereign window on screen.

The ToplevelLayout struct is necessary for using ToplevelExt::present().

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

Implementations

impl ToplevelLayout

pub fn new() -> ToplevelLayout

Create a toplevel layout description.

Used together with gdk_toplevel_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_factor()).

Returns

newly created instance of ToplevelLayout

pub fn copy(&self) -> ToplevelLayout

pub fn fullscreen(&self) -> Option<bool>

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.

Returns

whether the @self specifies the fullscreen state for the toplevel

fullscreen

location to store whether the toplevel should be fullscreen

pub fn fullscreen_monitor(&self) -> Option<Monitor>

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

Returns

the monitor on which @self fullscreens

pub fn maximized(&self) -> Option<bool>

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 fullscreen, or false, if it should go unmaximized.

Returns

whether the @self specifies the maximized state for the toplevel

maximized

set to true if the toplevel should be maximized

pub fn is_resizable(&self) -> bool

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

Returns

true if the layout is resizable

pub fn set_fullscreen(
    &self,
    fullscreen: bool,
    monitor: Option<&impl IsA<Monitor>>
)

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

fullscreen

true to fullscreen the surface

monitor

the monitor to fullscreen on

pub fn set_maximized(&self, maximized: bool)

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

maximized

true to maximize

pub fn set_resizable(&self, resizable: bool)

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

resizable

true to allow resizing
