[英]Java&JFreeChart - How to set a JFreeChart's ChartPanel resize with it's container ( say JPanel )?
I just found that when i add a ChartPanel to a JFrame, the ChartPanel will resize to fit the frame as the JFrame dragged larger or smaller. 我刚刚发现,当我将ChartPanel添加到JFrame时,随着JFrame拖动的变大或变小,ChartPanel将调整大小以适合框架。 However, when i add the ChartPanel to a JPanel, the JPanel's size( width and height ) changes to fit the JFrame as the JFrame resized.
但是,当我将ChartPanel添加到JPanel时,随着JFrame调整大小,JPanel的大小(width和height)会更改以适合JFrame。 But the ChartPanel just keeps it's dimensions, leaving the enlarged JPanel a lot of empty space.
但是,ChartPanel仅保留其尺寸,从而使扩大的JPanel留有很多空白空间。 How to make ChartPanel resize with it's container in GUI?
如何在GUI中使用ChartPanel的容器调整大小?
Here is my sample codes : 这是我的示例代码:
ChartPanel chartPanel = new ChartPanel(createWhateverChart()); JFrame frame = new JFrame(); frame.add(chartPanel);
ChartPanel chartPanel = new ChartPanel(createWhateverChart()); JPanel panel = new JPanel("Who cares"); panel.add(chartPanel, BorderLayout.CENTER); JFrame frame = new JFrame(); frame.add(panel);
Try my code and it works fine. 试试我的代码,它可以正常工作。
Note that : 注意 :
I have one frame which contains a panelMain, A panelMain contains a subPanel and a subPanel contains ChartPanel. 我有一帧包含一个panelMain,panelMain包含一个subPanel,一个subPanel包含ChartPanel。
frame.setLayout(new BoxLayout(frame.getContentPane(), BoxLayout.Y_AXIS));
JPanel panelMain = new JPanel(new GridLayout(0,2));
ChartPanel chartPanel = createChart();
JPanel subPanel = new JPanel(new BorderLayout());
subPanel.setBorder(BorderFactory.createTitledBorder("Consommation"));
subPanel.setPreferredSize(new Dimension(400, 200));
subPanel.add(chartPanel);
panelMain.add(subPanel);
frame.add(panelMain);
frame.pack();
frame.setLocationRelativeTo(null);
frame.setVisible(true);
And now when you resize your window application. 现在,当您调整窗口应用程序的大小时。 Your chartPanel will resized automatically.
您的chartPanel会自动调整大小。 Hope this helps.
希望这可以帮助。
