Java JPanel定位不正确
我用Java做了一个游戏，你应该猜一个随机生成的整数，在1-100之间。如果您猜得太低，文本字段将填充一个文字，上面写着“太低”，但是瑞典语。如果你猜得太高也一样 当答案正确时，问题就出现了，然后我调用一个方法使一个不可见的JPanel可见。这很好，但是Jpanel本身不会达到它应该达到的最高点。因为它只是背景的一张经过Photoshop处理的图片，所以它需要完美贴合。背景的属性为：1920 x 1080。经光处理的GG WP的特性为1920 x 297。Jpane被称为“grattis” 我希望我没有错过一些重要的事情，我感谢所有能得到的帮助，因为我现在陷入困境 抱歉英文和格式不好Java JPanel定位不正确,java,image,swing,jpanel,jlabel,Java,Image,Swing,Jpanel,Jlabel,我用Java做了一个游戏，你应该猜一个随机生成的整数，在1-100之间。如果您猜得太低，文本字段将填充一个文字，上面写着“太低”，但是瑞典语。如果你猜得太高也一样 当答案正确时，问题就出现了，然后我调用一个方法使一个不可见的JPanel可见。这很好，但是Jpanel本身不会达到它应该达到的最高点。因为它只是背景的一张经过Photoshop处理的图片，所以它需要完美贴合。背景的属性为：1920 x 1080。经光处理的GG WP的特性为1920 x 297。Jpane被称为“grattis” 我希
