lookup_icon

Description:

public IconPaintable lookup_icon (string icon_name, string[]? fallbacks, int size, int scale, TextDirection direction, IconLookupFlags flags)

Looks up a named icon for a desired size and window scale, returning a `GtkIconPaintable`.

The icon can then be rendered by using it as a `GdkPaintable`, or you can get information such as the filename and size.

If the available icon_name is not available and fallbacks are provided, they will be tried in order.

If no matching icon is found, then a paintable that renders the "missing icon" icon is returned. If you need to do something else for missing icons you need to use [method@Gtk.IconTheme.has_icon].

Note that you probably want to listen for icon theme changes and update the icon. This is usually done by overriding the GtkWidgetClass.css-changed() function.

Parameters:

this	a `GtkIconTheme`
icon_name	the name of the icon to lookup
size	desired icon size.
scale	the window scale this will be displayed on
direction	text direction the icon will be displayed in
flags	flags modifying the behavior of the icon lookup

Returns:

a `GtkIconPaintable` object containing the icon.
