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 () 或 reject ().
This enum describes the type of the requested access: read, write or both. The options can be OR-ed together from the following list:
常量 | 值 |
---|---|
QWebEngineFileSystemAccessRequest::Read
|
0x1
|
QWebEngineFileSystemAccessRequest::Write
|
0x2
|
The AccessFlags type is a typedef for QFlags <AccessFlag>. It stores an OR combination of AccessFlag values.
This enum describes the type of the requested file system entry.
