Anyway I could do this. basically I just want to customize my JFileChooser: 回答1: The file chooser wasn't designed to be customized in this way.

问题 Basically, I want to make a rectangle that contains a mouse listener for my tic tac toe game. I intend to place them in between the lines to serve as mouse listeners. I have already set up a JFrame, all that is left is for me to add the rectangle. How would I go about doing this?

问题 I have this code, which basically initializes a new JFrame and sets it full screen public class FullScreenFrameTest extends JFrame { public FullScreenFrameTest() { super(); initFrame(); setVisible(true); //full screen GraphicsEnvironment env = GraphicsEnvironment.getLocalGraphicsEnvironment(); GraphicsDevice device = env.getDefaultScreenDevice(); device.setFullScreenWindow(this); //end full screen } public void initFrame() { Dimension screen = Toolkit.getDefaultToolkit().getScreenSize();

问题 When you create JFrame instance, you have setBackground method available from this instance. However, regardless to what color you try to put there, you`ll receive gray background color. This happens (as i understood), because default JPanel instance is automatically created inside JFrame and lays over it . So, to get color set, you need to call JFrame.getContentPane().setBackground(Color.RED); that actually calls setBackground of default JPanel , that exists inside JFrame . I also tried to

问题 This question already has an answer here : How to wait for a JFrame to close before continuing? (1 answer) Closed 6 years ago .

问题 I am trying to create a simple JFrame menu where there is a nice background, which works, along with some text. The text is a bit buggy. Here is how it looks (http://imgur.com/nRpzA30) As you can see, only one line of the text appears not the second line. Along with that. Two GUI's appear when I run the program. One is completley empty, and one looks like the picture above. Finally I can't use the method logo.setHorizontalAlignment(JLabel.NORTH); without getting an error, same with a few

问题 So for the sake of simplicity I set up a little test code just to figure out this problem. Basically I have a JFrame and I added 'this' to it (I just extended my main class from JComponent to save time). this component fills in a red background. Then I have it sleep for 2 seconds and then type this. f.remove(this); thing t = new thing(); f.add(t); f.setVisible(true); f being my JFrame object and 'thing' is just another class extending JComponent that paints a blue background.. when I comment

问题 I want to get the mouse position of my JFrame. But when mouse is on its child component (such as a table, button that is added to the JFrame) MouseMotion event is no more listening. How can I get the mouse position? 回答1: Assuming the use-case in your comment is the real issue to solve, the answer is to implement the mouseExited such that it checks whether the mouse is still somewhere over the frame and hide it only if not. Something like: MouseListener closer = new MouseAdapter() { @Override
