开关¶

开关是一种具有两种状态的 UI 控制，即“开”和“关”。

开关小部件的状态由 GtkSwitch:active 属性跟踪。

开关的标签¶

概述一些功能的章节

GtkWidget *box = gtk_box_new (GTK_ORIENTATION_HORIZONTAL, 6);

GtkWidget *label = gtk_label_new ("Enable awesomeness");
GtkWidget *sw = gtk_switch_new ();

gtk_box_append (GTK_BOX (box), label);
gtk_box_append (GTK_BOX (box), sw);

// The switch__notify_active() function is defined elsewhere
g_signal_connect (sw, "notify::active",
                  G_CALLBACK (switch__notify_active),
                  NULL);

box = Gtk.Box(orientation=Gtk.Orientation.HORIZONTAL, spacing=6)

label = Gtk.Label(text="Enable awesomeness")
sw = Gtk.Switch()

box.append(label)
box.append(sw)

# The switch__notify_active() method is defined elsewhere
sw.connect("notify::active", self.switch__notify_active)

var box = new Gtk.Box (Gtk.Orientation.HORIZONTAL, 6);

var label = new Gtk.Label ("Enable awesomeness");
var sw = new Gtk.Switch ();

box.append (label);
box.append (sw);

// The switch__notify_active() method is defined elsewhere
sw.notify["active"].connect (switch__notify_active);

const box = new Gtk.Box({
  orientation: Gtk.Orientation.HORIZONTAL,
  spacing: 6,
});

const label = new Gtk.Label({ label: "Enable awesomeness" });
const sw = new Gtk.Switch();

box.append(label);
box.append(sw);

// The switch__notify_active() method is defined elsewhere
sw.connect("notify::active", switch__notify_active);

组件的常用方法¶

带有助记符的标签应调用 set_mnemonic_widget() 来激活开关；请参阅标签组件的教程。
可以使用 GtkSwitch::state-set 信号来控制开关的状态，然后再更改 GtkSwitch:active 属性。
