Expand description

Trait containing manually implemented methods of Editable.

Provided Methods§

Source

fn connect_insert_text<F>(&self, f: F) -> SignalHandlerId
where F: Fn(&Self, &str, &mut i32) + 'static,

Emitted when text is inserted into the widget by the user.

The default handler for this signal will normally be responsible for inserting the text, so by connecting to this signal and then stopping the signal with g_signal_stop_emission(), it is possible to modify the inserted text, or prevent it from being inserted entirely.

§text

the new text to insert

§length

the length of the new text, in bytes, or -1 if new_text is nul-terminated

§position

the position, in characters, at which to insert the new text. this is an in-out parameter. After the signal emission is finished, it should point after the newly inserted text.

Dyn Compatibility§

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
