Provided Methods

fn content_changed(&self)

Emits the ::content-changed signal.

fn attach_clipboard(&self, clipboard: &Clipboard)

fn detach_clipboard(&self, clipboard: &Clipboard)

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

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>>

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
