class Gtk::ColorDialog

Overview

Asynchronous API to present a color chooser dialog.

Gtk::ColorDialog collects the arguments that are needed to present the dialog to the user, such as a title for the dialog and whether it should be modal.

The dialog is shown with the Gtk::ColorDialog#choose_rgba function.

See Gtk::ColorDialogButton for a convenient control that uses Gtk::ColorDialog and presents the results.

Defined in:

lib/gi-crystal/src/auto/gtk-4.0/color_dialog.cr

Class Method Detail

def self.g_type : UInt64 #

Returns the type id (GType) registered in GLib type system.


Instance Method Detail

def ==(other : self) #
Description copied from class Reference

Returns true if this reference is the same as other. Invokes same?.


def choose_rgba(parent : Gtk::Window | Nil, initial_color : Gdk::RGBA | Nil, cancellable : Gio::Cancellable | Nil, &callback : Gio::AsyncReadyCallback) : Nil #

Presents a color chooser dialog to the user.


def choose_rgba_finish(result : Gio::AsyncResult) : Gdk::RGBA | Nil #

Finishes the Gtk::ColorDialog#choose_rgba call


def hash(hasher) #
Description copied from class Reference

See Object#hash(hasher)


def modal : Bool #

Returns whether the color chooser dialog blocks interaction with the parent window while it is presented.


def modal=(modal : Bool) : Nil #

Sets whether the color chooser dialog blocks interaction with the parent window while it is presented.


def modal? : Bool #

def title : String #

Returns the title that will be shown on the color chooser dialog.


def title=(title : String) : Nil #

Sets the title that will be shown on the color chooser dialog.


def title=(value : Nil) : Nil #

Set #title property to nil.


def title? : String | Nil #

Same as #title, but can return nil.


def with_alpha : Bool #

Returns whether colors may have alpha.


def with_alpha=(with_alpha : Bool) : Nil #

Sets whether colors may have alpha.


def with_alpha? : Bool #
