问题 I want to draw a simple board made of Graphics2D rectangles but I also want to have one JButton under this board. I know the exact dimensions of this board in pixels and I was trying to deal with getContentPane() method and BoxLayout, like this: frame.getContentPane().add(board); frame.getContentPane().add(Box.createRigidArea(new Dimension(bWidth, bHeight))); frame.getContentPane().add(new JButton("Start")); frame.pack(); But RigidArea isn't truly invisible and it overrides my drawings. Could

问题 I have a frame, inside this frame I have a panel with box layout, inside this panel I have 4 more panels. mainFrame = new JFrame("Basket Game"); mainPanel = new JPanel(); mainPanel.setLayout(new BoxLayout(mainPanel, BoxLayout.Y_AXIS)); mainPanel.add(options); mainPanel.add(pname); mainPanel.add(info); mainPanel.add(gamearea); mainFrame.setContentPane(mainPanel); mainFrame.pack(); mainFrame.getContentPane().setBackground(Color.LIGHT_GRAY); mainFrame.setResizable(false); mainFrame.setVisible

问题 I want to stack some JComponents vertically inside a JPanel so they stack at the top and any extra space is at the bottom. I'm using a BoxLayout. The components will each contain a JTextArea that should allow the text to wrap if necessary. So, basically, I want the height of each of these components to be the minimum necessary for displaying the (possibly wrapped) text. Here's a contained code example of what I'm doing: import javax.swing.*; import java.awt.*; public class TextAreaTester {

问题 I'm writing a MathQuiz for my pupils including JLatexMath for rendering and jinput for the buzzers. The problem is, that sometimes (like every fourth time) when I start the program, none of the components are visible. They appear after resizing the JFrame. First I was thinking of Bugs in the jinput or jlatexMath libraries, but I do get the same Error even with this minimal Code: public class Shell extends JFrame{ private JButton button1; private JButton button2; private Formula formula;

问题 I have a JPanel with a vertical BoxLayout on top of a JPanel with a null layout. I would like the JPanel with the BoxLayout to grow as the components are being added. See this code: public static void main (String[] args) { JFrame f = new JFrame(); f.setSize(500,500); f.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE); JPanel total = new JPanel(); total.setLayout(null); total.setSize(f.getWidth(),f.getHeight()); total.setBackground(Color.green); JPanel box = new JPanel(); box.setLocation(100
