From Newsgroup: comp.lang.tcl
I've just released a pure Tcl/Tk 9 module, flowrow-1.tm,
with no external dependencies.
The module can be used for creating and managing toolbars that automatically adapts to the application’s width.
The `flowrow::Row` class is used to manage flowrow (`ttk::frame` widgets)
which themselves contain widgets (often ``ttk::button``s; but labels,
entries, and spinboxes all work too).
Included with the module is the flowrow_test.tk application which
shows most of the module's facilities in action.
The module's web page also has some screenshots of flowrow_test.tk and also ste.tk and wishlists.tk two applications that make use of flowrow.
