Whether to show the apply button.
When set to TRUE, typing text in the entry will reveal an apply button. Clicking it or pressing the <kbd>Enter</kbd> key will hide the button and emit the signal@EntryRow::apply signal.
This is useful if changing the entry contents can trigger an expensive operation, e.g. network activity, to avoid triggering it after typing every character.
