Gtk.Button.new_from_stock

function new_from_stock(stock_id:String):Gtk.Widget {
    // Gjs wrapper for gtk_button_new_from_stock()
}

Creates a new Gtk.Button containing the image and text from a stock item. Some stock ids have preprocessor macros like #GTK_STOCK_OK and #GTK_STOCK_APPLY.

If stock_id is unknown, then it will be treated as a mnemonic label (as for Gtk.new_with_mnemonic).
