Provided Methods§
sourcefn content_changed(&self)
fn content_changed(&self)
Emits the ::content-changed signal.
fn attach_clipboard(&self, clipboard: &Clipboard)
fn detach_clipboard(&self, clipboard: &Clipboard)
sourcefn 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
sourcefn storable_formats(&self) -> ContentFormats
fn storable_formats(&self) -> ContentFormats
Gets the formats that the provider suggests other applications to store the data in.
An example of such an application would be a clipboard manager.
This can be assumed to be a subset of ContentProviderExt::formats()
.
§Returns
The storable formats of the provider
fn write_mime_type_future( &self, mime_type: &str, stream: &OutputStream, io_priority: Priority ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + 'static>>
sourcefn value(&self, type_: Type) -> Result<Value, Error>
fn value(&self, type_: Type) -> Result<Value, Error>
Gets the contents of @self stored in @value.
The @value will have been initialized to the GType
the value should be
provided in. This given GType
does not need to be listed in the formats
returned by ContentProviderExt::formats()
. However, if the
given GType
is not supported, this operation can fail and
G_IO_ERROR_NOT_SUPPORTED
will be reported.
§Returns
true
if the value was set successfully. Otherwise
@error will be set to describe the failure.
§value
the GValue
to fill
