If you have created your own package and you want it to be automatically considered in the Gui-Widget-List, the Statechart Editor, etc., you can specify your package in the AdditionalPackages property. This list is specified in the Application properties. To specify your additional default package list, edit the ~/.armarx/default.cfg file and add/edit the following line:

ArmarX.AdditionalPackages=${YOURPACKAGENAME},${YOURPACKAGENAME2}

To see the default value of the "ArmarX.DefaultPackages" (the default packages of ArmarX) property you can execute any ArmarX application and pass it the "--help" parameter. This will tell the application to print all properties, a description, and the default value thereof to the console.
