最初,我使用的代码运行良好,但有点复杂。将方法的某些部分移入 JFrame 的构造函数后,一切正常。
除了使用 pack() 使框架大小合适之外的所有内容。
原代码如下:
public class BaseGameFrame extends JFrame {
public static final int WINDOWED = 0;
public static final int UFS = 1;
protected BaseGamePanel gamePanel;
public BaseGameFrame(String title, int pWidth, int pHeight, long period, int windowType){
super(title);
switch(windowType){
case UFS:
this.setUndecorated(true);
Rectangle screenSize = this.getGraphicsConfiguration().getBounds();
pWidth = screenSize.width;
pHeight = screenSize.height;
break;
default: break;
}
this.setVisible(true);
this.setResizable(false);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
this.createPanel(pWidth, pHeight, period);
}
protected void createPanel(final int pWidth, final int pHeight, long period){
this.gamePanel = new BaseGamePanel(pWidth, pHeight, period);
this.add(this.gamePanel);
this.pack();
}
public static void main(String[] args){
new BaseGameFrame("Test", 800, 600, 20L * 1000000L, UFS);
}
}
这里是修改后的样子:
public class BaseGameFrame extends JFrame {
protected BaseGamePanel gamePanel;
public BaseGameFrame(String title, VideoType vType, BaseGamePanel gp){
super(title);
switch(vType){
case UFS:
this.setUndecorated(true);
Rectangle screenSize = this.getGraphicsConfiguration().getBounds();
gp.setPDimensions(new Dimension(screenSize.width, screenSize.height));
break;
default: break;
}
this.add(gp);
this.pack();
this.setVisible(true);
this.setResizable(false);
this.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}
public static void main(String[] args){
BaseGamePanel gp = new BaseGamePanel(800, 600, 20L * 1000000L);
new BaseGameFrame("Test", VideoType.UFS, gp);
}
}
我不太确定问题出在哪里.. 但最终发生的是这样的:
最佳答案
确保在调用 pack()
或 setVisible(true)
之前调用 setResizable(false)

关于java - 为什么调用 JFrame.pack() 会增加额外的空间?,我们在Stack Overflow上找到一个类似的问题: https://stackoverflow.com/questions/14595897/
