ConnectToFrontEnd[]
establishes a link to the notebook front end for use by the UseFrontEnd[] function.

DetailsDetails

  • To use ConnectToFrontEnd, you first need to load J/Link using Needs["JLink`"].
  • ConnectToFrontEnd returns True to indicate that the link was established correctly, and False otherwise.
  • The front end will be launched if required.
  • Although UseFrontEnd will call ConnectToFrontEnd if necessary, ConnectToFrontEnd is provided to allow programmers to conveniently control when the front end is launched and to receive a True/False indication of whether it was successful.
  • This function will typically be called only from an external program that is driving the kernel, not from code executing in a front end notebook.
