      public void setInvalid(boolean invalid)
      Description copied from interface: SupportsValidation
      Sets invalid state to the field considering result of field validation.
      • Invalid - false and validation passed - false = field is invalid
      • Invalid - false and validation passed - true = field is valid
      • Invalid - true and validation passed - false = field is invalid
      • Invalid - true and validation passed - true = field is invalid
      Specified by:
      setInvalid in interface com.vaadin.flow.component.HasValidation
      Specified by:
      setInvalid in interface SupportsValidation<byte[]>
      Parameters:
      invalid - whether field should be invalid

    • setStatusChangeHandler

      public void setStatusChangeHandler(@Nullable Consumer<SupportsStatusChangeHandler.StatusContext<FileUploadField>> handler)
      Description copied from interface: SupportsStatusChangeHandler
      Sets a callback to be used to handle component status changes, e.g. validation messages set by HasValidation.setErrorMessage(String).
      Specified by:
      setStatusChangeHandler in interface SupportsStatusChangeHandler<FileUploadField>
      Parameters:
      handler - a handler to set

    • setMaxFileSize

      public void setMaxFileSize(int maxFileSize)
      Specify the maximum file size in bytes allowed to upload. Notice that it is a client-side constraint, which will be checked before sending the request.

      Note if MultipartProperties is available, the default value will be set from MultipartProperties.getMaxFileSize() that is equal to 1Mb. To increase maximum file size for all fields in the application use MultipartProperties.getMaxFileSize() property.

      Overrides:
      setMaxFileSize in class AbstractSingleUploadField<FileUploadField,byte[]>
      Parameters:
      maxFileSize - the maximum file size in bytes
