relacing 'g.drawRoundRect (...)' no parece trivial, la OMI. Pero es un comienzo: tendrías que dibujar las esquinas redondeadas y los bordes por separado. – Thomas
@Thomas Más fácil decirlo que hacerlo: P Me falta dibujar las esquinas redondeadas con arcos. Lo he estado intentando pero aún no lo logro. – David
Ahora todo lo que necesitamos es el código fuente de drawRoundRect ... – David
