我需要在屏幕上放置JFrame.但我无法让它们出现在屏幕底部的右侧.
请有人解释我如何定位它们,如果你能描述如何做,那就太好了.
这是迄今为止的代码.
//Gets the screen size and positions the frame left bottom of the screen
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice defaultScreen = ge.getDefaultScreenDevice();
Rectangle rect = defaultScreen.getDefaultConfiguration().getBounds();
int x = (int)rect.getMinX();
int y = (int)rect.getMaxY()- frame.getHeight();
frame.setLocation(x,y - 45);
解决方法
试试下面的例子.请注意07000“如何调整此窗口的大小以适合其子组件的首选大小和布局.”
import java.awt.Dimension;
import java.awt.EventQueue;
import java.awt.GraphicsDevice;
import java.awt.GraphicsEnvironment;
import java.awt.Rectangle;
import javax.swing.JFrame;
import javax.swing.JPanel;
/** @see https://stackoverflow.com/q/9753722/230513 */
public class LowerRightFrame {
private void display() {
JFrame f = new JFrame("LowerRightFrame");
f.add(new JPanel() {
@Override // placeholder for actual content
public Dimension getPreferredSize() {
return new Dimension(320,240);
}
});
f.pack();
f.setDefaultCloSEOperation(JFrame.EXIT_ON_CLOSE);
GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
GraphicsDevice defaultScreen = ge.getDefaultScreenDevice();
Rectangle rect = defaultScreen.getDefaultConfiguration().getBounds();
int x = (int) rect.getMaxX() - f.getWidth();
int y = (int) rect.getMaxY() - f.getHeight();
f.setLocation(x,y);
f.setVisible(true);
}
public static void main(String[] args) {
EventQueue.invokeLater(new Runnable() {
@Override
public void run() {
new LowerRightFrame().display();
}
});
}
}
