The [https://aplsimple.github.io/en/tcl/pave/index.html%|%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:
* 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
* setting a natural tab order of widgets
* theming both ttk and non-ttk widgets
* centralizing things like icons or popup menus
* providing ''mega-attributes'', right up to the user-defined ones
* providing ''mega-widgets''
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:
* 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, with entry, text, combobox, file content combobox, spinbox, listbox, file listbox, tablelist, option cascade, checkbutton, radiobutton, label, title label
* to resize windows neatly (however strange, not done in Tk standard dialogs)
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'':
* file picker
* saved file picker
* directory picker
* font picker
* color picker
* date picker
* menubar
* toolbar
* statusbar
* file combobox
* file listbox
* file viewer/editor
* option cascade
* e_menu
* bartabs
* link
* baltip
* gutter
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 [https://wiki.tcl-lang.org/page/How+to+build+good+packages%|%How to build good packages%|%] ("avoid simple, obvious names for your namespace"). Let it be a sort of ''a-pave''.

[Jeff Smith] 2021-01- : 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.
