Mám PyQT aplikace s toolbar, sada tlačítka, a spodní řada dalších tlačítek. Chtěl bych přidat TextEdit pod spodním řádku, který uživatel může zobrazit nebo skrýt. Já bych jako TextEdit rozšířit spodní část, když je prokázáno, ale, když uživatel skryje to, rád bych, že spodní část odstraněna bez ovlivnění výšky, šířky, nebo dimenzování některé z ostatních tlačítek. Představte si, že jen s nůžky na TextEdit sekce, když uživatel skryje, ale pak lepení zpět, když uživatel chce zpátky. Je to vůbec možné udělat v PyQt? Nejbližší jsem našel, je realizace níže, která změní všechny tlačítka.
