I am trying to use an image I made in photoshop as the background for my GUI. How do I do that? also I made some images I want to display in the button backgrounds after the action is performed... For the JButton, use this: JButton button = new JButton("Button Name", new ImageIcon("foo.png"); The Panel is a bit more interesting. This is a good method, though: ImagePanel panel = new ImagePanel(new ImageIcon("foo.png").getImage()); 来源： https://stackoverflow.com/questions/8373006/using-an-image-for-the-background-of-a-jpanel-and-jbutton

The idea of my program is to select one name from a list that saved before in other JFrame. I'd like to print in the label all names one after the other with small delay between them, and after that stop at one of them. The problem is that lbl.setText("String"); doesn't work if there is more than one setText code. Here is the part of my code : public void actionPerformed(ActionEvent e) { if (RandomNames.size != 0) { for (int i = 0; i < 30; i++) { int rand = (int)(Math.random() * RandomNames.size); stars.setText(RandomNames.list.get(rand)); try { Thread.sleep(100); } catch (InterruptedException

I have a problem in my application using line primitives and JLables . I try to explain it: I have to draw a vehicle route using lines to represent roads and JLabels to represent cities. I need the use of JLabels because each JLabel has a Listener that shows a dialog with information about the city. I redefine paint() method of my main JPanel . In that method I first in invoke the super.paint() , then I draw the lines and finally I add the Labels to the JPanel . The problem is that the lines overlap the labels regardless the matter the order of painting them. Is there any suggestion? You can
