That's great DJ

I think our guest spike is due to nDoom, maybe the user spike is because of the CX. Or maybe no particular reason.

Before every action, you could store the screen to an OS Pic variable, and then using Undo would recall the pic var onto the screen, effectively "undoing" the last action

But that would only allow one undo. That's not enough. I want the ability to undo ad infinitum.

Then it'd requite saving infinite Pic Variables, but they are finite.

My BASIC program Macro is a drawing tool. There are 8 drawing commands available, and the coordinates for each are recorded and stored, along with the command number, in a single element of _LM. It's almost done, but it's missing a desperately needed feature: An undo button. I can't just do the opposite of the command that was just performed, because that could change pixels that weren't changed by the instruction being undone. The only way I can see to circumvent this situation would be to remove the last element of the list and call Read to redraw the whole thing, which would be an absolute pain. Can anyone think up a more efficient way to implement an undo feature?

In computer programs, what is usually done is to save all the things that are done and then undo them, but this is theory, I have no idea about the practical way of 'Undo' in Basic.

Hmmm it seems that you create the progress bar, but it never interacts with the loadingBarFrame.  I am not very familiar with swing components, do you need to add it into the frame or whatnot?

Thanks, the .add( method did it

No it doesn't, I was kidding, never mind.

are you sure that it is rendering the screen correctly?  you see, if you were using netbeans instead it has a built in editor that lets you actually place the buttons and bars and such manually in a graphical way

I know, but I'm not using that. I'm programming the GUI, I only use that for big frames and complicated stuff.

package gamepanel;

import javax.swing.*;

public class Main {
    public static void main(String[] args) {
        JFrame loadingBarFrame = new JFrame();
        loadingBarFrame.setSize(400,100);
        loadingBarFrame.setVisible(true);
        JProgressBar progressBar = new JProgressBar();
        progressBar.setVisible(true);
        progressBar.setLocation(5,5);
        progressBar.setSize(1000,1000);
        progressBar.setValue(0);
        progressBar.setStringPainted(true);
    }
}

I have this code which is supposed to create a simple progress bar and a frame, however, the progress bar doesn't appear for some obvious reason I'm not aware of, any ideas?
