#[repr(transparent)]pub struct Surface { /* private fields */ }
Expand description
A Surface
is a rectangular region on the screen.
It’s a low-level object, used to implement high-level objects
such as Gtk::Window
or Gtk::Dialog
in GTK.
The surfaces you see in practice are either Toplevel
or
Popup
, and those interfaces provide much of the required
API to interact with these surfaces. Other, more specialized surface
types exist, but you will rarely interact with them directly.
This is an Abstract Base Class, you cannot instantiate it.
Properties
cursor
The mouse pointer for the Surface
.
Readable | Writeable
display
The Display
connection of the surface.
Readable | Writeable | Construct Only
frame-clock
The FrameClock
of the surface.
Readable | Writeable | Construct Only
height
The height of the surface, in pixels.
Readable
mapped
Whether the surface is mapped.
Readable
scale-factor
The scale factor of the surface.
Readable
width
The width of the surface in pixels.
Readable
Signals
enter-monitor
Emitted when @surface starts being present on the monitor.
event
Emitted when GDK receives an input event for @surface.
layout
Emitted when the size of @surface is changed, or when relayout should be performed.
Surface size is reported in ”application pixels”, not ”device pixels” (see gdk_surface_get_scale_factor()).
leave-monitor
Emitted when @surface stops being present on the monitor.
render
Emitted when part of the surface needs to be redrawn.

pub const NONE: Option<&'static Surface> = None
sourcepub fn new_popup(parent: &impl IsA<Surface>, autohide: bool) -> Surface
pub fn new_popup(parent: &impl IsA<Surface>, autohide: bool) -> Surface
Create a new popup surface.
The surface will be attached to @parent and can be positioned
relative to it using PopupExt::present()
.
parent
the parent surface to attach the surface to
autohide
whether to hide the surface on outside clicks
Returns
a new Surface
