ei Pessoal,
Programei um JavaBeans pra colocar dentro da Palheta do NetBeans, e esta’ dando um Estranho Erro quando salva, alem de nao dar o Refresh dentro do Form NetBeans.
E isto esta acontencendo quando uso java.awt.Image como propriedade.
seque o Erro :
‘Cannot Save the value of “backgroundImage” Property’
codigo do JavaBeans :
public class JPanel_Image extends JPanel {
java.awt.Image img = null;
public void setBackgroundImage(java.awt.Image newImage) {
Image old_img = img;
img = newImage;
propertyChangeListeners.firePropertyChange("backgroundImage", old_img, img );
}
public void paintComponent(Graphics g) {
super.paintComponent(g);
if ( !(img == null) ) {
Graphics2D g2D = (Graphics2D)g;
w = getSize().width;
h = getSize().height;
g2D.drawImage(img,0,0,img.getWidth(this),img.getHeight(this),this);
}
}
