如何将最小化的jinternalframe保持在最顶层
5 java layout swing jinternalframe jdesktoppane
我有四个内部框架和3个按钮.当我按下最大化按钮时,最大化但是它与所有框架重叠.但我的观点是它应该显示最小化的框架.请找到下面的代码

try {
new Test();
} catch (HeadlessException ex) {
//Logger.getLogger(MinPanel1.class.getName()).log(Level.SEVERE, null, ex);
} catch (PropertyVetoException ex) {

}
}
});
}
private void createAndShowGUI() throws HeadlessException, PropertyVetoException {
JFrame frame = new JFrame();
frame.setResizable(true);
frame.setDefaultCloseOperation(JFrame.DISPOSE_ON_CLOSE);
final JDesktopPane jdp = new JDesktopPane() {
@Override
public Dimension getPreferredSize() {
return new Dimension(400, 400);
}
};
frame.setContentPane(jdp);
frame.pack();
createAndAddInternalFrame(jdp, 0, 0);
createAndAddInternalFrame(jdp, 200, 0);
createAndAddInternalFrame(jdp, 400, 0);
createAndAddInternalFrame(jdp, 600, 0);
frame.setVisible(true);
}
private void createAndAddInternalFrame(final JDesktopPane jdp, int x, int y) throws PropertyVetoException {
final JInternalFrame jInternalFrame = new JInternalFrame("Test1", true, true, true, true);
jInternalFrame.setLocation(x, y);
final JInternalFrame jInternalFrame1 = new JInternalFrame("Test2", true, true, true, true);
JPanel jp= new JPanel();
JButton jb1 = new JButton("min");
JButton jb2 = new JButton("[]");
JButton jb3 = new JButton("X");
jInternalFrame.setLayout(new GridLayout(2, 2,2,2));
jInternalFrame1.add(jb1);
jInternalFrame.setSize(200, 200);//testing
jInternalFrame.setLayout(new GridLayout(2,2));
JButton jb= new JButton("min");
// jInternalFrame.add(jb);
// jInternalFrame.add(jb3);
//jInternalFrame.add(jb2);

jp.add(jb2);
jp.add(jb3);
jInternalFrame.add(jp);
jb.addActionListener(new ActionListener()
{
@Override

try {
jInternalFrame.setIcon(true);
} catch (PropertyVetoException ex) {
}
}
});
jb1.addActionListener(new ActionListener()
{
@Override
public void actionPerformed(ActionEvent ae) {
try {
jInternalFrame.setIcon(true);
} catch (PropertyVetoException ex) {
}
}
});
jb2.addActionListener(new ActionListener()
{
@Override
public void actionPerformed(ActionEvent ae) {
try {
jInternalFrame.setMaximum(true);
}
catch(Exception e)
{
}
}
});jb3.addActionListener(new ActionListener()
{
@Override
public void actionPerformed(ActionEvent ae) {
try {
jInternalFrame.dispose();
} catch (Exception ex) {
}
}
});
BasicInternalFrameTitlePane titlePane = (BasicInternalFrameTitlePane) ((BasicInternalFrameUI) jInternalFrame.getUI()).getNorthPane();
jInternalFrame.remove(titlePane);
jInternalFrame.setVisible(true);
jInternalFrame1.setVisible(true);
jdp.add(jInternalFrame);
//jdp.add(jInternalFrame1);
}
}
你可以尝试:JDesktopPane#setComponentZOrder(Component com, int i).
根据文档:
将指定的组件移动到容器中指定的z-order索引.z顺序决定了组件的绘制顺序; 首先具有最高z次序涂料的组件和具有最低z次序涂料的组件持续.在组件重叠的情况下,具有较低z次序的组件在具有较高z次序的组件上绘制.
...
注意:
并非所有平台都支持将重量级组件的z顺序从一个容器更改为另一个容器,而无需调用removeNotify.无法检测平台是否支持此功能,因此开发人员不应做出任何假设.
这将允许您设置其中JInternalFrame包含的s 的顺序JDesktopPane.
更新:
根据我的评论:
从我可以看到它的默认行为,似乎没有超过COM-能够通过
JDesktopPane#setComponentZOrder(Component com, int i)时,JInternalFrame被图标化.它处于正常状态时工作正常
解:
我建议调整JInternalFrame显示最大化的图层:
jb2.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent ae) {
try {
if (jInternalFrame.isMaximum()) {//restore
jInternalFrame.pack();
} else {//maximize
jInternalFrame.setMaximum(true);
}
jdp.remove(jInternalFrame);
jdp.add(jInternalFrame, JDesktopPane.FRAME_CONTENT_LAYER);
jdp.revalidate();
jdp.repaint();
} catch (Exception e) {
e.printStackTrace();
}
}
});
我们也必须忘记将其添加回DEFAULT_LAYER最小化时:
jb.addActionListener(new ActionListener() {
@Override
public void actionPerformed(ActionEvent ae) {
try {
if (jInternalFrame.getLayer() == JDesktopPane.FRAME_CONTENT_LAYER) {
jdp.remove(jInternalFrame);
jdp.add(jInternalFrame, JDesktopPane.DEFAULT_LAYER);
jdp.revalidate();
jdp.repaint();
}
jInternalFrame.pack();
jInternalFrame.setIcon(true);
} catch (PropertyVetoException ex) {
}
}
});
