Below are requirements for using Designer to edit or create new QtVCP screens or panels:

Required packages:
qttools5-dev
qttools5-dev-tools
libpython3-dev

To enable LinuxCNC specific widgets to appear in Designer:

1. Create the plugin directory for designer to search:
    mkdir -p ~/.designer/plugins/python

2. Copy the <pluginfile> to the above directory:
    cp <pluginfile> ~/.designer/plugins/python/

The <pluginfile> is dependent on the type of LinuxCNC installation.

For a package installation:
    /usr/lib/python3/dist-packages/qtvcp/plugins/qtvcp_plugin.py

For a RIP installation:
    ~/linuxcnc-dev/lib/python/qtvcp/plugins/qtvcp_plugin.py

Designer can now be run and the LinuxCNC widgets will be available.

For a RIP install only:
    source ~/linuxcnc-dev/scripts/rip-environment

Start designer with:
    designer -qt=5
