I am trying to create a simple GUI. I have a menu bar that is filled with various JMenuItems. Each menu item should link to a different "window". Currently, I am thinking the best way to do this is to create a single frame, and create various JPanels. My ActionListeners will toggle visibility of the different panels, and only one panel should be visible at a time. Is this the best way to go about the task? Or is there a better workaround.

I have a small piece of code that I use to keep track of time - very simply it takes a picture of my desktop every four minutes so that later I can go back over what I've been up to during the day - It works great, except when I connect to an external monitor - this code only takes a screen shot of my laptop screen, not the larger external monitor I'm working from - any ideas how to change the code?

I have an app that is written in Swing, awt. I want to prevent users from pasting values into the textfields. is there any way to do this without using action listeners? You can just call setTransferHandler with a null parameter like this: textComponent.setTransferHandler(null); This will disable all copy/paste actions on the field. The best way is to remove action associated with CTRL+V keystroke in components ActionMap. Rob The simplest way it to say: textComponent.setEditable(false); This disables cut & paste, but copy is still enabled. public class PastlessJTextField extends JTextField {

I have a problem. I want to ask you how can I implement GlassPane to paint on it. I mean, if I click mouse button, in mouseClicked event, my transparent glass pane should be created, because I want to see all my components behind glassPane and I can paint on it using mouseDragged event. When I release mouse button my glassPane disappears. I have another question too. When I will paint on glass pane all my components behind them will be refreshing and repainting? Maybe somebody have nice example with glass pane which might help me. How to Create Translucent and Shaped Windows 来源： https:/

I'm trying to get a BufferedImage from raw samples, but I get exceptions about trying to read past the available data range which I just don't understand. What I'm trying to do is: val datasize = image.width * image.height val imgbytes = image.data.getIntArray(0, datasize) val datamodel = new SinglePixelPackedSampleModel(DataBuffer.TYPE_INT, image.width, image.height, Array(image.red_mask.intValue, image.green_mask.intValue, image.blue_mask.intValue)) val buffer = datamodel.createDataBuffer val raster = Raster.createRaster(datamodel, buffer, new Point(0,0)) datamodel.setPixels(0, 0, image
