frame.addComponentListener(
new ComponentAdapter(){
public void componentResized(ComponentEvent arg0){
label_scrolledText(label);
}
});
}
public void label_scrolledText(JLabel label) {
this.scrolledText = this.str;
label.setText(scrolledText);
FontMetrics metrics = label.getFontMetrics(label.getFont());
int textW = metrics.stringWidth(label.getText());
Dimension frameSize = frame.getSize();
for (int i = 1; i = (frameSize.width - textW) / 3 - 3; i++)
scrolledText += " ";
label.setText(scrolledText);
Thread thread = new Thread(new TextChanger(label));
thread.start();
}
}
