I'm doing this project using Swing. To add a more welcoming feel to the UI, I'm also adding a few Photoshopped images as the background.Here's where the problem begins... I want the images to automatically resize themselves once the size of the window is increased or decreased, how can I make this happen ?

推荐答案

一种方法是覆盖 JPanel 的 paintComponent(...) 方法以使用 drawImage 绘制图像(....) 方法.

One way is to override the paintComponent(...) method of a JPanel to paint the image using the drawImage(....) method.

另一种选择是使用带有图标的 JLabel 作为框架的背景.然后您可以使用 Stretch Icon 它将根据标签可用的空间.这是最灵活的解决方案，因为 StretchIcon 可用于任何支持图标的组件.

Another option is use a JLabel with an Icon as the background for the frame. Then you can use the Stretch Icon which will automatically scale based on the space available to the label. This is the most flexible solution since the StretchIcon can be used on any component that supports icons.

您还可以查看 背景面板，它允许显示图像.您可以按实际大小、缩放或平铺显示图像.

You can also check out the Background Panel which allows you to display an image. You can display the image at its actual size, scaled or tiled.
