如何在打印的页面上居中 jPanel？

Question

我正在打印收据，这太棒了。打印时是否有直接的方法使 jPanel 在页面上居中？

感谢您的帮助。

Answer 1

有一个半直接的方法。

public int print(Graphics g, PageFormat pf, int pageIndex) {
  Component myPanel =...;
  g.translate(pf.getImageableX() + pf.getImageableWidth() / 2 - myPanel.getWidth() / 2, pf.getImageableY() + pf.getImageableHeight() / 2 - myPanel.getHeight() / 2);
  //Graphics object has been set up so the printing myPanel with it should now be centered
  myPanel.print(g);
}
