The apave v3.2.7 package provides a sort of geometry manager for Tcl/Tk.
The apave 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:
The apave is implemented as APave oo::class, so that you can enhance it with your own inherited / mixin-ed class.
While APave oo::class allows to layout highly sophisticated windows, you can also employ its more 'earthy' descendants:
APaveDialog and APaveInput allow you:
The theming facility of apave is enabled by ObjectTheming oo::class which embraces both ttk and non-ttk widgets.
Along with standard widgets, the mentioned apave classes provide a batch of following mega-widgets:
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 apave originates from the old pave package, to comply with How to build good packages ("avoid simple, obvious names for your namespace"). Let it be a sort of a-pave.

Jeff Smith 2021-01-21 : Below is an online demo using CloudTk. This demo runs "Pave, sort of geometry manager" in an Alpine Linux Docker Container. It is a 28.4MB image which is made up of Alpine Linux + tclkit + Pave-sort-of-geometry-manager.kit + libx11 + libxft + fontconfig + ttf-linux-libertine. It is run under a user account in the Container. The Container is restrictive with permissions for "Other" removed for "execute" and "read" for certain directories.
Jeff Smith Without looking at the code this demo appears to disconnect at times. I think it maybe because when changes occur the Tk app gets "Restarted" and CloudTk disconnects the session if the Tk app disappears.

Hi Jeff,
Thanks for your attention, I'm kinda touched.
As for restarting, you could imitate it with this start of test2_pave.tcl:
test2_pave.tcl 0 14 12 "middle icons"
where:
By the way, this start resolves a problem with color schemes: when CS is set at start, no blinking occurs at switching tabs, resizing etc.
Also, I have to note that test2_pave.tcl is a test & demo, i.e. something preparatory. Hopefully, it would be followed by something real.
Regards, Alex
Jeff Smith 2021-01-22 : Hi Alex, I made the changes as suggested. With the increased font and icon sizes, it may be better to click on the noVNC control bar tab at the side of the iFrame and select "Fullscreen" for viewing this demo.
