Provided Methods

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.

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.
