Métodos

Reference of a method attached to the object. Pode-se utilizar um método de formulário para gerir dados e objectos, mas é geralmente mais simples e mais eficiente utilizar um método de objecto para estes fins. Ver Métodos especializados.

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

São suportados vários tipos de referências de métodos:

  • a standard object method file path, i.e. that uses the following pattern:
    ObjectMethods/objectName.4dm
    ... where objectName is the actual object name. This type of reference indicates that the method file is located at the default location ("sources/forms/formName/ObjectMethods/"). In this case, 4D automatically handles the object method when operations are executed on the form object (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 object operations.

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