Java getClass().getResource on a png returning Null Pointer

由 瘦欲@ 提交于 2019-12-02 13:18:20
I am not sure if I am referring to the right location with this code, the images I am trying to access are titled Flower0.png etc. They are located in the same directory as the rest of my code for this project. This class is in a src folder called hangman.ui and the .png files are located in a directory folder called Resources . Perhaps getClass().getResource is not right? This is my first time trying to put images into a GUI. Help is much appreciated! public WiltingFlowerRendererRemix(HangmanLogic logic) { panel = new JPanel(); panel.setLayout(new BorderLayout()); imageLabel = new JLabel();

The program has images that need to be loaded for the program to work properly and I want it all to be contained in the one jar. Currently it doesn't work from the executable jar or when I run it through command line. It works in netbeans however. Here's the code I'm using: To load the image I'm using: protected ImageIcon createImageIcon(String path, String description) { java.net.URL imgURL = getClass().getClassLoader

Using an image for the background of a JPanel and JButton

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

问题 I'm trying to get a jpeg to display on a JFrame and I'm noticing that some image files work while others do not. I'm using Eclipse and all of my images are in the project's root dir. When I run the Debugger and it hits my breakpoint it reports the imageheight and imagewidth as -1 on the images that will not display. It reports the correct values on the images that do display. at first I thought it had something to do with the image sizes but after playing with resolutions in mspaint I've
