Expand description
Required methods
fn content_changed(&self)
fn content_changed(&self)
Emits the ::content-changed signal.
fn formats(&self) -> ContentFormats
fn formats(&self) -> ContentFormats
Gets the formats that the provider can provide its current contents in.
Returns
The formats of the provider
fn storable_formats(&self) -> ContentFormats
fn storable_formats(&self) -> ContentFormats
Asynchronously writes the contents of self
to stream
in the given
mime_type
.
When the operation is finished callback
will be called. You must then call
Gdk::
ContentProvider::write_mime_type_finish()`` to get the result
of the operation.
The given mime type does not need to be listed in the formats returned by
formats()
. However, if the given GType
is
not supported, G_IO_ERROR_NOT_SUPPORTED
will be reported.
The given stream
will not be closed.
mime_type
the mime type to provide the data in
stream
the GOutputStream
to write to
io_priority
I/O priority of the request.
cancellable
optional GCancellable
object, None
to ignore.
callback
callback to call when the request is satisfied
fn write_mime_type_async_future<P: IsA<OutputStream> + Clone + 'static>(
&self,
mime_type: &str,
stream: &P,
io_priority: Priority
) -> Pin<Box_<dyn Future<Output = Result<(), Error>> + 'static>>
fn connect_content_changed<F: Fn(&Self) + 'static>(
&self,
f: F
) -> SignalHandlerId
fn connect_content_changed<F: Fn(&Self) + 'static>(
&self,
f: F
) -> SignalHandlerId
Emitted whenever the content provided by this provider has changed.
