Top-level windows in Tycho are all derived from a common baseclass that
provides some rudimentary capabilities.
To create a top-level window with a specified geometry, you can use
the following pair of commands:
::tycho::TopLevel .t -geometry 300x300+0+0
wm deiconify .t
Alternatively, instead of the "wm deiconify" method,
we could have requested that the window be centered on the screen using
the centerOnScreen method:
.t centerOnScreen
You can prevent interactive
resizing of the window with the following
command. Before you execute it, verify that you can interactively
resize the window we have created using whatever mechanism your window
manager supports. Then do this, use the
freezeWindowSize method:
.t freezeWindowSize
You can also move or resize the window by configuring its
geometry option:
.t configure -geometry 100x100-0+0
delete object .t
