Start window in specific size and location, is there a general tool can do that?

Question

Is there a general program, that start my GUI program, and able to specify the size and location of this program ? Not just X programs, but also other GUI libs.

Answer 1

Devil's Pie does have such an option. See e.g. the Ubuntu wiki and this howto. In X11 parlance, a window's size and location make up its geometry. Write something like

(if (is (application_name) "Foo")
    (geometry "400x200-0+20"))
