Witam.
Zrobiłem coś co powinno rysować wybrana figurę niestety program nie działa.
W kodzie są takie obiekty jak:
textBox1 - wpisywanie dlugosci a lub r
textBox2 -wpisywanie dl b (tam gdzie potrzebne (kwadrat trojkat)
textBox3- wspolrzena x
textBox4- wsp y
ComboBox -> Selekcja figury - index 0 kwadrat, 1 prostokat,2 trojkat,3 koło
oto kod (program kompiluje sie poprawnie ale nic nie rysuje :(
