Gtk::Settings::Settings | ( | Settings && | src | ) |
| noexcept

## ◆ ~Settings()

Gtk::Settings::~Settings | ( |  | ) |
| override noexcept

## Member Function Documentation

## ◆ get_default()

static Glib::RefPtr<Settings> Gtk::Settings::get_default | ( |  | ) |
| static

Gets the `Gtk::Settings` object for the default display, creating it if necessary.

See gtk_settings_get_for_display().

Returns
  A `Gtk::Settings` object. If there is no default display, then returns `nullptr`.

## ◆ get_for_display()

static Glib::RefPtr<Settings> Gtk::Settings::get_for_display | ( | const Glib::RefPtr< Gdk::Display > & | display | ) |
| static

Gets the `Gtk::Settings` object for display, creating it if necessary.

Parameters

  display | A `Gdk::Display`.

Returns
  A `Gtk::Settings` object.

## ◆ get_type()

static GType Gtk::Settings::get_type | ( |  | ) |
| static

Get the GType for this class, for use with the underlying GObject type system.

## ◆ gobj() [1/2]

GtkSettings* Gtk::Settings::gobj | ( |  | ) |
| inline

Provides access to the underlying C GObject.

## ◆ gobj() [2/2]

const GtkSettings* Gtk::Settings::gobj | ( |  | ) | const
| inline

Provides access to the underlying C GObject.

## ◆ gobj_copy()

GtkSettings* Gtk::Settings::gobj_copy | ( |  | ) |

Provides access to the underlying C instance. The caller is responsible for unrefing it. Use when directly setting fields in structs.

## ◆ operator=()

Settings& Gtk::Settings::operator= | ( | Settings && | src | ) |
| noexcept

## ◆ property_gtk_alternative_button_order() [1/2]

Glib::PropertyProxy< bool > Gtk::Settings::property_gtk_alternative_button_order | ( |  | ) |

Whether buttons in dialogs should use the alternative button order.

Default value: `false`

Returns
  A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

## ◆ property_gtk_alternative_button_order() [2/2]

Glib::PropertyProxy_ReadOnly< bool > Gtk::Settings::property_gtk_alternative_button_order | ( |  | ) | const

Whether buttons in dialogs should use the alternative button order.

Default value: `false`

Returns
  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

## ◆ property_gtk_alternative_sort_arrows() [1/2]

Glib::PropertyProxy< bool > Gtk::Settings::property_gtk_alternative_sort_arrows | ( |  | ) |

Controls the direction of the sort indicators in sorted list and tree views.

By default an arrow pointing down means the column is sorted in ascending order. When set to `true`, this order will be inverted.

Default value: `false`

Returns
  A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

## ◆ property_gtk_alternative_sort_arrows() [2/2]

Glib::PropertyProxy_ReadOnly< bool > Gtk::Settings::property_gtk_alternative_sort_arrows | ( |  | ) | const

Controls the direction of the sort indicators in sorted list and tree views.

By default an arrow pointing down means the column is sorted in ascending order. When set to `true`, this order will be inverted.

Default value: `false`

Returns
  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

## ◆ property_gtk_application_prefer_dark_theme() [1/2]

Glib::PropertyProxy< bool > Gtk::Settings::property_gtk_application_prefer_dark_theme | ( |  | ) |

Whether the application prefers to use a dark theme.

If a GTK theme includes a dark variant, it will be used instead of the configured theme.

Some applications benefit from minimizing the amount of light pollution that interferes with the content. Good candidates for dark themes are photo and video editors that make the actual content get all the attention and minimize the distraction of the chrome.

Dark themes should not be used for documents, where large spaces are white/light and the dark chrome creates too much contrast (web browser, text editor...).

Default value: `false`

Returns
  A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

## ◆ property_gtk_application_prefer_dark_theme() [2/2]

Glib::PropertyProxy_ReadOnly< bool > Gtk::Settings::property_gtk_application_prefer_dark_theme | ( |  | ) | const

Whether the application prefers to use a dark theme.

If a GTK theme includes a dark variant, it will be used instead of the configured theme.

Some applications benefit from minimizing the amount of light pollution that interferes with the content. Good candidates for dark themes are photo and video editors that make the actual content get all the attention and minimize the distraction of the chrome.

Dark themes should not be used for documents, where large spaces are white/light and the dark chrome creates too much contrast (web browser, text editor...).

Default value: `false`

Returns
  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

## ◆ property_gtk_cursor_aspect_ratio() [1/2]

Glib::PropertyProxy< double > Gtk::Settings::property_gtk_cursor_aspect_ratio | ( |  | ) |

The aspect ratio of the text caret.

Default value: 0.04

## ◆ property_gtk_cursor_aspect_ratio() [2/2]

Glib::PropertyProxy_ReadOnly< double > Gtk::Settings::property_gtk_cursor_aspect_ratio | ( |  | ) | const

The aspect ratio of the text caret.

Default value: 0.04

Returns
  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

## ◆ property_gtk_cursor_blink() [1/2]

Glib::PropertyProxy< bool > Gtk::Settings::property_gtk_cursor_blink | ( |  | ) |

Whether the cursor should blink.

Also see the property_gtk_cursor_blink_timeout() setting, which allows more flexible control over cursor blinking.

Default value: `true`

Returns
  A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

## ◆ property_gtk_cursor_blink() [2/2]

Glib::PropertyProxy_ReadOnly< bool > Gtk::Settings::property_gtk_cursor_blink | ( |  | ) | const

Length of the cursor blink cycle, in milliseconds.

Default value: 1200

Returns
  A PropertyProxy that allows you to get or set the value of the property, or receive notification when the value of the property changes.

## ◆ property_gtk_cursor_blink_time() [2/2]

Glib::PropertyProxy_ReadOnly< int > Gtk::Settings::property_gtk_cursor_blink_time | ( |  | ) | const

Length of the cursor blink cycle, in milliseconds.

Default value: 1200

Returns
  A PropertyProxy_ReadOnly that allows you to get the value of the property, or receive notification when the value of the property changes.

## ◆ property_gtk_cursor_blink_timeout() [1/2]

Glib::PropertyProxy< int > Gtk::Settings::property_gtk_cursor_blink_timeout | ( |  | ) |

Time after which the cursor stops blinking, in seconds.

The timer is reset after each user interaction.

Setting this to zero has the same effect as setting property_gtk_cursor_blink() to `false`.
