## Detailed Description

Represents registered icon sizes.

You can also use a Gtk::BuiltinIconSize instead of an IconSize.

## Constructor & Destructor Documentation

Gtk::IconSize::IconSize | ( |  | ) | `[inline]`

Gtk::IconSize::IconSize | ( | BuiltinIconSize | size | ) | `[inline]`

Gtk::IconSize::IconSize | ( | int | size | ) | `[inline, explicit]`

## Member Function Documentation

static IconSize Gtk::IconSize::from_name | ( | const Glib::ustring & | name | ) | `[static]`

Looks up the icon size associated with name.

Parameters:

  | name | the name to look up. result The icon size with the given name.

static Glib::ustring Gtk::IconSize::get_name | ( | IconSize | size | ) | `[static]`

Gets the canonical name of the given icon size.

Parameters:

  | size | size AnIconSize.

Returns:
  The name of the given icon size.

static bool Gtk::IconSize::lookup | ( | IconSize | size,
|  | int & | width,
|  | int & | height,
|  | const Glib::RefPtr< Gtk::Settings >& | settings |
| ) |  |  | `[static]`

Obtains the pixel size of a semantic icon size, possibly modified by user preferences for a particular Gtk::Settings.

Normally size would be Gtk::ICON_SIZE_MENU, Gtk::ICON_SIZE_BUTTON, etc. This function isn't normally needed because Gtk::Widget::render_icon() is the usual way to get an icon for rendering - then just look at the size of the rendered pixbuf. The rendered pixbuf may not even correspond to the width/height returned by IconSize::lookup(), because themes are free to render the pixbuf however they like, including changing the usual size.

Parameters:

  | size | An icon size.
  | width | Location to store icon width.
  | height | Location to store icon height.
  | settings | A Gtk::Settings object, used to determine which set of user preferences to used.

Returns:
  true if size was a valid size.

Since gtkmm 2.14:

static bool Gtk::IconSize::lookup | ( | IconSize | size,
|  | int & | width,
|  | int & | height |
| ) |  |  | `[static]`

Obtains the pixel size of a semantic icon size, possibly modified by user preferences for the default Gtk::Settings.

Normally size would be Gtk::ICON_SIZE_MENU, Gtk::ICON_SIZE_BUTTON, etc. This function isn't normally needed because Gtk::Widget::render_icon() is the usual way to get an icon for rendering - then just look at the size of the rendered pixbuf. The rendered pixbuf may not even correspond to the width/height returned by IconSize::lookup(), because themes are free to render the pixbuf however they like, including changing the usual size.

Parameters:

  | size | An icon size.
  | width | Location to store icon width.
  | height | Location to store icon height.

Returns:
  true if size was a valid size.

Gtk::IconSize::operator int | ( |  | ) | const`[inline]`

static void Gtk::IconSize::register_alias | ( | const Glib::ustring & | alias,
|  | IconSize | target |
| ) |  |  | `[static]`

Registers alias as another name for target so calling from_name() with alias as argument will return target.

Parameters:

  | alias | An alias for target.
  | target | An existing icon size.

static IconSize Gtk::IconSize::register_new | ( | const Glib::ustring & | name,
|  | int | width,
|  | int | height |
| ) |  |  | `[static]`

Registers a new icon size, along the same lines as ICON_SIZE_MENU, etc.

Returns the integer value for the size.

Parameters:

  | name | Name of the icon size.
  | width | The icon width.
  | height | The icon height.

Returns:
  Integer value representing the size.
