IconTheme.lookupByGicon

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

iconthe #GIcon to look up
sizedesired icon size
flagsflags modifying the behavior of the icon lookup

Returns

a #GtkIconInfo containing

information about the icon, or null if the icon wasn’t found. Unref with [gobject.object.ObjectWrap.unref]
