Kaip Java kalboje sujungti figūras su jungtukais

Jungikliai „Aspose.Slides FOSS“ yra linijinės figūros, kurios prisijungia prie ryšio vietų kitų figūrų. Kai perkeliate sujungtą figūrą, jungiklio galinis taškas juda kartu su ja. Dažniausiai naudojamas jungiklio tipas yra BENT_CONNECTOR3, kuris aplengia kliūtis vienu alkūnės posūkiu.
