Bom dia precisa de uma ajuda, queria aumentar o tamanho do quadrado, quando utilizo o angulo 0 e 270 funciona normalmente, porém quando a palavra está com o angulo 90 e 180 quando aumenta com o mouse ele não respeita a r…

Aumentar tamanho do quadrado JAVA

txtpn1 = new JEditorPane() { @Override protected void paintComponent(Graphics g) { int angle = txtpn[0]; //Angulo 0,90,180,270 Graphics2D g2 = (Graphics2D) g; g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON); AffineTransform aT = g2.getTransform(); Shape oldshape = g2.getClip(); double x = getWidth() / 2.0; double y = getHeight() / 2.0; aT.rotate(Math.toRadians(angle), x, y); g2.setTransform(aT); super.paintComponent(g); } txtpn1.addMouseMotionListener(new MouseMotionAdapter() { @Override public void mouseDragged(MouseEvent arg0) { arrastarObejto(txtpn1, arg0); } } public void arrastarObejto(JComponent component, MouseEvent e) { if (component.getCursor().getType() != 11 && component.getCursor().getType() != 9) { component.setLocation(component.getLocation().x + e.getX(), component.getLocation().y + e.getY()); } if (component.getCursor().getType() == 11 || component.getCursor().getType() == 9) { component.setSize(e.getX(), e.getY()); } }
