Required Methods

fn connect_changed<F>(&self, changed_func: F) -> SignalHandlerId

where F: Fn(&Self) + 'static,

The ::changed signal is emitted at the end of a single user-visible operation on the contents of the Editable.

E.g., a paste operation that replaces the contents of the selection will cause only one signal emission (even though it is implemented by first deleting the selection, then inserting the new content, and may cause multiple ::notify::text signals to be emitted).

fn connect_delete_text<F>(&self, delete_text_func: F) -> SignalHandlerId

where F: Fn(&Self, i32, i32) + 'static,

This signal is emitted when text is deleted from the widget by the user. The default handler for this signal will normally be responsible for deleting the text, so by connecting to this signal and then stopping the signal with g_signal_stop_emission(), it is possible to modify the range of deleted text, or prevent it from being deleted entirely. The start_pos and end_pos parameters are interpreted as for EditableExt::delete_text().

start_pos

the starting position

end_pos

the end position

fn connect_insert_text<F>(&self, insert_text_func: F) -> SignalHandlerId

where F: Fn(&Self, &str, &mut i32) + 'static,

This signal is 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.

new_text

the new text to insert

new_text_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".
