  cd ~/Documents/ftrack/extensions/connect
  mkdir launch

  cd ~/Documents/ftrack/extensions/ftrack_example
  mkdir dialogs
  mkdir plugins
  mkdir tool-configs
  mkdir widgets

2. Follow the instructions on how to create each extension type:

3. Setup the FTRACK_CONNECT_EXTENSIONS_PATH environment variable to point to the extensions folder:

  export FTRACK_CONNECT_EXTENSIONS_PATH=~/Documents/ftrack/extensions/connect

4. Start Connect and launch a framework integration, your extension should now be visible under the ftrack menu.

📄️ Widget

This s the widget that will represent the maya reference collector plugin. The populatemethod is always called by the base Class, and the queryreferences is used to call the uihook method from the plugin to populate the UI. As the execution of the uihook is async, the result goes to the uihookcallback method. In the onreferencechanged method we modify the config of the plugin to set the selected_reference option.
