Updating a jframe


02-Jun-2020 08:33

I am following the 4 main hints provided in internet. In this manner, the number of flickering increases and it slows the application. Although, I am getting the correct output in my JTable (inside JFrame), but my point of view is for larger data the application will be extremely slow.

Please let me know if there is any way to completely destroy a JFrame when I am moving to a new one (so that the I can re-create the older one...run the application in a faster way)...

I've got a window belonging to a module in the project. Hallo all, I am working on an application and i am using AWT (because i don't know Swing! My application has a Frame using Border Layout and three Panels that are set in the WEST, SOUTH and CENTER positions of my Frame. My problem is this: If i press a button on the WEST Panel ..Event Dispatch Thread (EDT) handles the painting, so when you do a 'long task', the EDT is blocked until the long task is finished. the problem i am having is that it is a network program, and moves are sent from one game to the other.

you need to do your long task in a thread of its own, separate from the EDT here's a simple demo of your problem (blocking the EDT) import *; import event.*; import javax.swing.*; class Testing extends ...(); Box main = new Box(Box Layout. Y_AXIS); public JScroll Pane setup(){ JPanel top = new JPanel(); main2.add(main); Box button Box = new Box(Box Layout. Is there a way how to use repaint() or revalidate in my situation? when you make your move, everything works just fine. Why is it that when I don't implement Runnable and don't have an additional Thread and don't have Run() and put my paint Image() method anywhere else, no image is painted? draw Image() is called from within the method and no errors occur, but nothing else happens. You're adding your Mouse Listener from within the paint Component method.

I can now call the method from a non-static context. i have a jpanel that contains a scrollpane with a jtable in it. I am having a problem updating the contents of a JPanel inside a JFrame. In other words I want the destroy the panel I have up when I click a button ...

Paul, the above problem was stopping me make the changes in my ..do you update a jpanel? i have a jpanel that contains a scrollpane with a jtable in it. initially, the panel displays the current data of the jtable. I wanted to update the JPanel by means of re-initializing the JPanel by other class extended by JPanel.

Back to the topic, when you add new data to your collection, you should invoke and that should resolve the problem you're facing (assuming that other parts of your code are working properly, since your code is not SSCCE so I couldn't test it myself).

Edit: I must notice that you constantly avoid using code tags in your posts.

Also, this is set up fairly poorly in two classes because I'll need a while loop running at one point (single LED blinking on/off until keypress), and I need to set up the Key Listener in another thread I think.

On the other side, your GUI class would be responsible for what it should be in the first place - displaying data and interacting with user.
