IconTheme.lookupByGicon
gtk.icon_info.IconInfo lookupByGicon(gio.icon.Icon icon, int size, gtk.types.IconLookupFlags flags)Looks up an icon and returns a #GtkIconInfo containing information such as the filename of the icon. The icon can then be rendered into a pixbuf using [gtk.icon_info.IconInfo.loadIcon].
When rendering on displays with high pixel densities you should not use a size multiplied by the scaling factor returned by functions like [gdk.window.Window.getScaleFactor]. Instead, you should use [gtk.icon_theme.IconTheme.lookupByGiconForScale], as the assets loaded for a given scaling factor may be different.
Parameters
icon | the #GIcon to look up |
size | desired icon size |
flags | flags modifying the behavior of the icon lookup |
Returns
a #GtkIconInfo containing
