## Detailed Description

To allow web applications to access local files of the computer, applications must connect to QWebEnginePage::fileSystemAccessRequested, which takes a QWebEngineFileSystemAccessRequest instance as an argument.

If a web applications requests access to local files or directories, QWebEnginePage::fileSystemAccessRequested will be emitted with an QWebEngineFileSystemAccessRequest instance as an argument where accessFlags() indicates the type of the requested access: read, write or both. The signal handler needs to then either call accept() or reject().

## Member Type Documentation

### enum QWebEngineFileSystemAccessRequest::AccessFlag
flags QWebEngineFileSystemAccessRequest::AccessFlags

This enum describes the type of the requested access: read, write or both. The options can be OR-ed together from the following list:

Constant | Value
--- | ---
`QWebEngineFileSystemAccessRequest::Read` | `0x1`
`QWebEngineFileSystemAccessRequest::Write` | `0x2`

The AccessFlags type is a typedef for QFlags<AccessFlag>. It stores an OR combination of AccessFlag values.

### enum QWebEngineFileSystemAccessRequest::HandleType

This enum describes the type of the requested file system entry.

Constant | Value
--- | ---
`QWebEngineFileSystemAccessRequest::File` | `0`
`QWebEngineFileSystemAccessRequest::Directory` | `1`

## Property Documentation

### `[read-only]` accessFlags : const AccessFlags

Contains the requested file access rights.

Access functions:

QWebEngineFileSystemAccessRequest::AccessFlags | accessFlags() const

### `[read-only]` filePath : const QUrl

Returns the file path this file system access request is referring to.

Access functions:

QUrl | filePath() const

### `[read-only]` handleType : const HandleType

Returns the type of the requested file system entry. (File or directory)

Access functions:

QWebEngineFileSystemAccessRequest::HandleType | handleType() const

### `[read-only]` origin : const QUrl

This property holds the URL of the web page that issued the file system access request.

Access functions:

QUrl | origin() const

## Member Function Documentation

### `[noexcept default]` QWebEngineFileSystemAccessRequest::QWebEngineFileSystemAccessRequest(QWebEngineFileSystemAccessRequest &&other)

Move-constructs an instance of QWebEngineFileSystemAccessRequest.

### `[invokable]` void QWebEngineFileSystemAccessRequest::accept()

Accepts the request to access local files.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

### `[invokable]` void QWebEngineFileSystemAccessRequest::reject()

Rejects a request to access local files.

Note: This function can be invoked via the meta-object system and from QML. See Q_INVOKABLE.

## Related Non-Members

### `[noexcept]` bool operator!=(const QWebEngineFileSystemAccessRequest &lhs, const QWebEngineFileSystemAccessRequest &rhs)

Returns `true` if lhs and rhs point to different requests.

### `[noexcept]` bool operator==(const QWebEngineFileSystemAccessRequest &lhs, const QWebEngineFileSystemAccessRequest &rhs)

Returns `true` if lhs and rhs both point to the same request.
