In general, if you re using Swing, you should only use Swing components. Mixing Swing and AWT components in the same GUI leads to strange results. So I would use a JPanel, or a raw JComponent.
Canvas is an AWT Object;JPanel is a Lightetter Java Swing Object. 如果您有 Java· Sw,我强烈建议使用<条码>。 JPanel。

In the simplest case, you use a
JPanelexactly the same way as you would aPanel. Allocate it, drop components in it, then add theJPanelto someContainer. However,JPanelalso acts as a replacement forCanvas(there is noJCanvas)...
或者,如果你想要显示像
BufferedImage image=
new BufferedImage(100, 50, BufferedImage.TYPE_INT_ARGB);
Graphics2D g2 = image.createGraphics();
// draw
g2.draw(new Ellipse2D.Double(x, y, rectwidth,rectheight));
g2.fill (new Ellipse2D.Double(0, 0, 100, 50));
JLabel label = new JLabel(new ImageIcon( image ));
这种局面取决于你们喜欢的东西,但我要使用JFrame,它直接创造了一个窗口,你可以利用这个窗口。 Canvas有其优势,它让你书写一个较少的进口产品,它还把窗户与纸面图分开,但是它有没有窗户的不利条件。 它取决于你们的喜欢和需要。
