module Gdk::Toplevel

Overview

A Gdk::Toplevel is a freestanding toplevel surface.

The Gdk::Toplevel interface provides useful APIs for interacting with the windowing system, such as controlling maximization and size of the surface, setting icons and transient parents for dialogs.

Defined in:

lib/gi-crystal/src/auto/gdk-4.0/toplevel.cr

Constructors

• .cast(obj : GObject::Object) : self

  Cast a GObject::Object to self, throws a TypeCastError if the cast can't be made.

Class Method Summary

• .cast?(obj : GObject::Object) : self | Nil
• .g_type : UInt64
