Centering in a Layout -- TTk Template

[DrBuhu]

Are templates supposed to be a preview, or something that can be used?

Because when I was trying to style my project i noticed theres already a template called TTkApptemplet which would make my life a whole lot easier.

But i'm a bit unsure if or how to use it.
What I tried:

appTemplate = ttk.TTkAppTemplate(parent=root)
appTemplate.setWidget(title, position=16)

but it didn't get displayed

AppTemplate is a widget helper that I made to simplify some recurrent layouts,
normally I have a main, left and bottom area, but is capable to place the widgets in 7 different predefined spaces.
I didn't document it properly and I haven't write a tutoria because it is still in its early stage and there are few things that may change in the future (i.e. where the title or the menus are placed)

you can check an example here:

this widget is useful if you need to place the different elements in a layout of this kind:

        App Template Layout
        ┌─────────────────────────────────┐
        │         Header                  │
        ├─────────┬──────────────┬────────┤ H
        │         │   Top        │        │
        │         ├──────────────┤        │ T
        │         │              │        │
        │  Right  │   Main       │  Left  │
        │         │   Center     │        │
        │         │              │        │
        │         ├──────────────┤        │ B
        │         │   Bottom     │        │
        ├─────────┴──────────────┴────────┤ F
        │         Footer                  │
        └─────────────────────────────────┘
                  R              L

you don't have to define/place all of them, just the ones that you need (i.e. the ttkDesigner use the right for the widgets selector, main for the editor, top for the top buttons and so on)

import TermTk as ttk

root = ttk.TTk(layout=ttk.TTkGridLayout())

appTemplate = ttk.TTkAppTemplate(parent=root)

testWidgetLeft = ttk.TTkTestWidgetSizes()
testWidgetMain = ttk.TTkTestWidgetSizes()
logWidget = ttk.TTkLogViewer()

appTemplate.setWidget(widget=testWidgetMain, position=appTemplate.MAIN)
appTemplate.setWidget(widget=testWidgetLeft, position=appTemplate.LEFT, size=30)
appTemplate.setWidget(widget=logWidget, title='Log', position=appTemplate.BOTTOM, size=5)

root.mainloop()
