Version 11 of Pave, sort of geometry manager

The pave software provides a sort of geometry manager for Tcl/Tk.

The pave isn't designed to replace the existing Tk geometry managers (place, pack, grid). Rather the pave tries to simplify the window layout by using their best, by means of:

joining the power of grid and pack
uniting the creation of widgets with their layout (and mostly their configuration)
minimizing a coder's efforts at creating / modifying / removing widgets
theming both ttk and non-ttk widgets
providing mega-widgets

The pave is implemented as PaveMe oo::class, so that you can enhance it with your own inherited / mixin-ed class.

While PaveMe oo::class allows to layout highly sophisticated windows, you can also employ its more 'earthy' descendants - PaveDialog oo::class and PaveInput oo::class that allow you:

to call a variety of dialogs, optionally using a "Don't show again" checkbox and a tagged text
to use a variety of widgets in dialogs, including entry, text (incl. readonly and stand-alone), combobox (incl. file content), spinbox, checkbutton, radiobutton and label.
to resize windows neatly (however strange, not done in Tk standard dialogs)

At last, a stand-alone dialog allows not only to ask "OK/Cancel" or "Yes/No" returning 1/0 but also to set environment variables to use in shell scripts.

The theming facility of pave is enabled by ObjectTheming oo::class which embraces both ttk and non-ttk widgets, as seen on demo video.

Along with standard widgets, the mentioned pave classes provide a batch of following mega-widgets:
