- Method editable
int editable(int default_setting)
Returns whether the character at this location is within an editable region of text. Non-editable text is "locked" and can't be changed by the user via W(TextView). This function is simply a convenience wrapper around get_attributes(). If no tags applied to this text editability, default_setting will be returned.
You don't want to use this function to decide whether text can be inserted here, because for insertion you don't want to know whether the char at iter is inside an editable range, you want to know whether a new characer inserted here would be inside an editable range. Use can_insert() to handle this case.
