IconSize.lookup

bool lookup(gtk.types.IconSize size, out int width, out int height)

Obtains the pixel size of a semantic icon size size: #GTK_ICON_SIZE_MENU, #GTK_ICON_SIZE_BUTTON, etc. This function isn’t normally needed, gtk.icon_theme.IconTheme.loadIcon 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 gtk.global.iconSizeLookup, because themes are free to render the pixbuf however they like, including changing the usual size.

Parameters

`size`	an icon size (#GtkIconSize)
`width`	location to store icon width
`height`	location to store icon height

Returns

true if size was a valid size
