gobject:object-new (gtype &rest args)

gtype -- a g:type-t type ID of the g:object subtype to instantiate
args -- pairs of a property keyword and value

Creates a new instance of a g:object subtype and sets its properties. Construction parameters which are not explicitly specified are set to their default values. In the Lisp implementation this function calls the make-instance method to create the new instance.

(g:object-new "GtkButton" :label "text" :margin 6)
=> #<GTK:BUTTON {D941381}>    

This is equivalent to:

(make-instance 'gtk:button :label "text" :margin 6)
=> #<GTK:BUTTON {D947381}>
