pub struct FileHandleFlag(/* private fields */);
Expand description

This enum is used when opening a file to specify additional options which only apply to files and not to a generic QIODevice.

C++ enum: QFileDevice::FileHandleFlag.

C++ documentation:

This enum is used when opening a file to specify additional options which only apply to files and not to a generic QIODevice.

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

Implementations§

source§

impl FileHandleFlag

source

pub fn to_int(&self) -> c_int

source§

impl FileHandleFlag

source

pub const AutoCloseHandle: FileHandleFlag = _

The file handle passed into open() should be closed by close(), the default behavior is that close just flushes the file and the application is responsible for closing the file handle. When opening a file by name, this flag is ignored as Qt always owns the file handle and must close it. (C++ enum variant: AutoCloseHandle = 1)

source

pub const DontCloseHandle: FileHandleFlag = _

If not explicitly closed, the underlying file handle is left open when the QFile object is destroyed. (C++ enum variant: DontCloseHandle = 0)
