The apave software 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 apave tries to simplify the window layout by using their best, by means of:

* joining the power of grid and pack
* uniting a 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 oo::class and APaveInput 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, with entry, text (incl. readonly and stand-alone), combobox (incl. file content), spinbox, listbox, file listbox, tablelist, option cascade, checkbutton, radiobutton and label (incl. 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
* bar of tabs
* link

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.
