要获取JFrame窗口大小信息,可以使用以下命令-
environment.getMaximumWindowBounds();
对于屏幕尺寸-
config.getBounds()
对于框架尺寸-
frame.getSize());
以下是获取JFrame窗口大小信息的示例-
import java.awt.GraphicsConfiguration; import java.awt.GraphicsDevice; import java.awt.GraphicsEnvironment; import java.awt.Rectangle; import javax.swing.JFrame; public class SwingDemo { public static void main(String[] args) { GraphicsEnvironment environment = GraphicsEnvironment.getLocalGraphicsEnvironment(); Rectangle bounds = environment.getMaximumWindowBounds(); System.out.println("Screen Bounds = " + bounds); GraphicsDevice device = environment.getDefaultScreenDevice(); GraphicsConfiguration config = device.getDefaultConfiguration(); System.out.println("Screen Size = " + config.getBounds()); JFrame frame = new JFrame("Frame Info"); frame.setSize(500, 300); frame.setVisible(true); System.out.println("Frame Size = " + frame.getSize()); } }
输出结果
Screen Bounds = java.awt.Rectangle[x=0,y=0,width=1366,height=728] Screen Size = java.awt.Rectangle[x=0,y=0,width=1366,height=768] Frame Size = java.awt.Dimension[width=500,height=300]
