public class FileUploadItem extends CanvasItem
FormItem for uploading files using HTML5 file drop capabilities.

A FileUploadItem's `canvas` is a `FileDropZone`. The value of a FileUploadItem is the JavaScript File object(s) representing files the user added.

FileUploadItem is not the default for `binary` type fields. To use FileUploadItem for binary fields, set `DynamicForm.useFileUploadItem` to true on the form, or specify `editorType:"FileUploadItem"` on the field.

When the form is `saved`, files are uploaded automatically. Use `DynamicForm.showUploadProgress` to display upload progress.

Single File Upload

With the default setting of `multiple:false`, a FileUploadItem allows uploading a single file to a binary field on the DataSource. This is analogous to the standard `FileItem`.

Multiple File Upload

To upload multiple files, set `multiple:true` and configure a `DataSource` property pointing to a related DataSource that will store the files. This follows the same master-detail pattern as `MultiFileItem`:

- The form's DataSource is the "master" record (e.g., an email message)
- The FileUploadItem's `DataSource` is the "detail" DataSource storing files (e.g., email attachments)
- The detail DataSource must have a `foreignKey` linking to the master DataSource's primary key
- Each uploaded file creates a separate record in the detail DataSource

See `MultiFileItem` for an example of the DataSource setup required.

Multiple Binary Fields

A form can contain multiple FileUploadItems for different binary fields in the same DataSource. When the form is saved, all files are uploaded in a single request, creating one record with all binary fields populated. This differs from `FileItem` which has a limitation preventing multiple file uploads in a single form submission.

Note: If you want immediate upload on drop (like Gmail attachments), use a `FormItem.changed()` handler to call `DynamicForm.saveData()`.

  - ### changeAutoChildDefaults

    public static void changeAutoChildDefaults(String autoChildName, Canvas defaults)
    Changes the defaults for Canvas AutoChildren named `autoChildName`.
    Parameters:
      `autoChildName` - name of an AutoChild to customize the defaults for.
      `defaults` - Canvas defaults to apply. These defaults override any existing properties without destroying or wiping out non-overridden properties. For usage tips on this param, see `SGWTProperties`.
    See Also:
      - `AutoChildUsage`

  - ### changeAutoChildDefaults

    public static void changeAutoChildDefaults(String autoChildName, FormItem defaults)
    Changes the defaults for FormItem AutoChildren named `autoChildName`.
    Parameters:
      `autoChildName` - name of an AutoChild to customize the defaults for.
      `defaults` - FormItem defaults to apply. These defaults override any existing properties without destroying or wiping out non-overridden properties. For usage tips on this param, see `SGWTProperties`.
    See Also:
      - `AutoChildUsage`

  - ### changePickerIconDefaults

    public static void changePickerIconDefaults(FormItemIcon defaults)

  - ### setAcceptedFileTypes

    public FileUploadItem setAcceptedFileTypes(String... acceptedFileTypes)
    See `FileDropZone.acceptedFileTypes`.
    Parameters:
      `acceptedFileTypes` - New acceptedFileTypes value. Default value is null
    Returns:
      `FileUploadItem` instance, for chaining setter calls

  - ### getAcceptedFileTypes

    public String[] getAcceptedFileTypes()
    See `FileDropZone.acceptedFileTypes`.
    Returns:
      Current acceptedFileTypes value. Default value is null

  - ### setCanAddFilesOnClick

    public FileUploadItem setCanAddFilesOnClick(Boolean canAddFilesOnClick)
    See `FileDropZone.canAddFilesOnClick`.
    Parameters:
      `canAddFilesOnClick` - New canAddFilesOnClick value. Default value is null
    Returns:
      `FileUploadItem` instance, for chaining setter calls

  - ### getCanAddFilesOnClick

    public Boolean getCanAddFilesOnClick()
    See `FileDropZone.canAddFilesOnClick`.
    Returns:
      Current canAddFilesOnClick value. Default value is null

  - ### setCancelButtonTitle

    public FileUploadItem setCancelButtonTitle(String cancelButtonTitle)
    Custom `cancelButtonTitle` for this fileUploadItem's canvas. If unset, the default property will be used.
    Parameters:
      `cancelButtonTitle` - New cancelButtonTitle value. Default value is null
    Returns:
      `FileUploadItem` instance, for chaining setter calls

  - ### getCancelButtonTitle

    public String getCancelButtonTitle()
    Custom `cancelButtonTitle` for this fileUploadItem's canvas. If unset, the default property will be used.
    Returns:
      Current cancelButtonTitle value. Default value is null

  - ### getCanvas

    public FileDropZone getCanvas()
    The `FileDropZone` component that provides the drag-drop file selection UI.

    The FileDropZone is automatically created using the `canvasConstructor` and `canvasDefaults` properties. To customize the FileDropZone, either set properties directly on the FileUploadItem (which are passed through to the FileDropZone) or override `canvasDefaults`.

    Access the FileDropZone via `fileUploadItem.canvas` after the item is created.

    This component is an AutoChild named "canvas". For an overview of how to use and configure AutoChildren, see `Using AutoChildren`.

    Overrides:
      `getCanvas` in class `CanvasItem`
    Returns:
      Current canvas value. Default value is null

  - ### setCanvasConstructor

    public FileUploadItem setCanvasConstructor(String canvasConstructor)
    The class to use for the `Canvas` autoChild. Default is FileDropZone.
    Parameters:
      `canvasConstructor` - New canvasConstructor value. Default value is "FileDropZone"
    Returns:
      `FileUploadItem` instance, for chaining setter calls

  - ### getCanvasConstructor

    public String getCanvasConstructor()
    The class to use for the `Canvas` autoChild. Default is FileDropZone.
    Returns:
      Current canvasConstructor value. Default value is "FileDropZone"

  - ### setCanvasDefaults

    public FileUploadItem setCanvasDefaults(Map canvasDefaults)
    Default properties for the `Canvas` autoChild FileDropZone.

    The default implementation includes handlers that forward `FileDropZone.filesAdded()` and `FileDropZone.filesRemoved()` notifications to update the FormItem's value.

    When overriding, use `isc.addProperties()` to merge with the defaults rather than replacing them entirely, to preserve the value synchronization behavior.

    Parameters:
      `canvasDefaults` - New canvasDefaults value. Default value is {...}
    Returns:
      `FileUploadItem` instance, for chaining setter calls

  - ### getCanvasDefaults

    public Map getCanvasDefaults()
    Default properties for the `Canvas` autoChild FileDropZone.

    The default implementation includes handlers that forward `FileDropZone.filesAdded()` and `FileDropZone.filesRemoved()` notifications to update the FormItem's value.

    When overriding, use `isc.addProperties()` to merge with the defaults rather than replacing them entirely, to preserve the value synchronization behavior.

    Returns:
      Current canvasDefaults value. Default value is {...}

  - ### setClickToAddMessage

  - ### setDefaultProperties

    public static void setDefaultProperties(FileUploadItem fileUploadItemProperties)
    Class level method to set the default properties of this class. If set, then all existing and subsequently created instances of this class will automatically have default properties corresponding to the properties of the class instance passed to this function. This is a powerful feature that eliminates the need for users to create a separate hierarchy of subclasses that only alter the default properties of this class. Can also be used for skinning / styling purposes.

    Note: This method is intended for setting default attributes only and will affect all instances of the underlying class (including those automatically generated in JavaScript). This method should not be used to apply standard EventHandlers or override methods for a class - use a custom subclass instead. Calling this method after instances have been created can result in undefined behavior, since it bypasses any setters and a class instance may have already examined a particular property and not be expecting any changes through this route.

    Parameters:
      `fileUploadItemProperties` - properties that should be used as new defaults when instances of this class are created
    See Also:
      - `SGWTProperties`
