Installation

Make sure your python installation is 3.7 or higher.

You need the tk extension tkDnD for this framework. This can be automatically installed via pip argument. Make sure the python directory is writable (e.g. on Mac OSX, Python library are installed to /System/Library, which cannot be modified, even with sudo!).

pip install layoutx (minimal version)

pip install layoutx[more_widgets, styles] (full version)

python -m layoutx.install_tkdnd (install tkdnd)

The command line tool: lxdesigner can be used to easily design some forms.

For lxdesigner to function, you need to install addon more widgets.
