ttk (very BETA)

appJar includes experimental support for ttk, a tk themed widget set.

Setup

.go(useTtk=True)
Enabling ttk in the appJar constructor also sets the topLevel Frame to be a ttk.Frame - the preferred option.
.useTtk()
Calling this at the start of your program will tell it to use ttk widgets where possible.
.setTtkTheme(theme)
This allows you to choose which theme to use.

It's possible to switch on ttk theming from the command line.
Simply use the --ttk flag, with an optional theme name:

python3 themes.py --ttk  # turn on ttk widgets

Turn on ttk widgets and set a theme:

python3 themes.py --ttk aqua # turn on ttk with the aqua theme
