Method

Reference of a method attached to the form. Sie können eine Formularmethode zum Verwalten von Daten und Objekten verwenden. Für diese Zwecke ist es jedoch generell einfacher und effizienter, eine Objektmethode zu verwenden. See Specialized methods.

You do not call a form method—4D calls it automatically when an event involves the form to which the method is attached.

Several types of method references are supported:

• a standard project method file path, i.e. that uses the following pattern:
  method.4dm
  This type of reference indicates that the method file is located at the default location ("sources/{TableForms/numTable} | {Forms}/formName/"). In this case, 4D automatically handles the form method when operations are executed on the form (renaming, duplication, copy/paste...)

• a project method name: name of an existing project method without file extension, i.e.: myMethod In this case, 4D does not provide automatic support for form operations.

• a custom method file path including the .4dm extension, e.g.:
  MyMethods/myFormMethod.4dm You can also use a filesystem:
  /RESOURCES/Forms/FormMethod.4dm In this case, 4D does not provide automatic support for object operations.
