我希望我的JDesktopPane可以使其中的JInternalFrames最大化,并完全遮挡JDesktopPane的蓝色背景(至少在Mac上为蓝色)。如果运行此演示,则会看到如果最大化JInternalFrame,它不会占用整个JDesktopPane。如何设置JDesktopPane,以使JInternalFrame占用整个JDesktopPane?

在此图像中,我运行了以下代码,并按下了JInternalFrame上的最大化按钮,但JDesktopPane上仍然显示“蓝色”。



import java.awt.BorderLayout;
import javax.swing.JDesktopPane;
import javax.swing.JFrame;
import javax.swing.JInternalFrame;
import javax.swing.JTextArea;

/**

public class Temp {

    Temp() {
        boolean resizable = true;
boolean closeable = true;
boolean maximizable  = true;
boolean iconifiable = true;
String title = "Frame Title";
JInternalFrame iframe = new JInternalFrame(title, resizable, closeable, maximizable, iconifiable);

// Set an initial size
int width = 200;
int height = 50;
iframe.setSize(width, height);

// By default, internal frames are not visible; make it visible
iframe.setVisible(true);

// Add components to internal frame...
iframe.getContentPane().add(new JTextArea());

// Add internal frame to desktop
JDesktopPane desktop = new JDesktopPane();
desktop.add(iframe);

// Display the desktop in a top-level frame
JFrame frame = new JFrame();
frame.getContentPane().add(desktop, BorderLayout.CENTER);
frame.setSize(300, 300);
frame.setVisible(true);
    }
    public static void main (String[] args) {
        new Temp();
    }
}

您可以在Google上找到惊人的东西。我自己还没有检查过,但这可能会有所帮助
