问题 I am trying to update an ImageIcon on a JLabel which sits on a JLayeredPane, but there is a lot of latency between when the setting thread sends the proper state to the JLabel object and when the GUI displays the ImageIcon of the proper state.

The setting thread: new Thread(new Runnable() { // setting thread @Override

问题 I took a snip of a table in my application, and i want to display that snip in a tutorial section of the app. I can not get it to display with out being blurry. I don't know what is causing this.

If anything that resizes the image,

问题 Java JLabel icons are displaying with distorted pixels in JFrame . This is happening consistently with different png images (all 32x32). I am not scaling the images, they are displayed in the program 32x32, which I verified using getWidth and getHeight on the JLabel. The distortions appear in the same place each time the program is run, not randomly. Screenshot using the example code provided below. In this screenshot you can see an array of JLabel icons, each affected one differently. When

问题 Hi i am trying to implement Action listener for JButton and code look like following: ImageIcon imageForOne = new ImageIcon(getClass().getResource("resources//one.png")); one = new JButton("",imageForOne); one.setPreferredSize( new Dimension(78, 76)); one.addActionListener(myButtonHandler); Using the above JButton it looks fine When i add specific value to button for e.g. ImageIcon imageForOne = new ImageIcon(getClass().getResource("resources//one.png")); //Check this one = new JButton("one"
