我如何从另一个jframe函数打开另一个jframe，而不必等待完成函数的执行？

Question

I want to show a progress bar. I put the code to open the JFrame containing progress bar at the beginning of the function. But the progress bar opens only after the complete execution of the function

public void function(){
    java.awt.EventQueue.invokeLater(new Runnable() {
        public void run() {
            new ProgressSearch().setVisible(true);
        }
    });

    instruction 1;
    instruction 2;
    instruction 3;
    instruction 4;
    instruction 5;
}

this code above only displays the progress bar after completing the function

Answer 1

Try adding static "progress fields" to your class. Then just update those fields as your JFrame is created, and get their values on your code using Class.StaticField

eg,

public class MyClass {
    public static PROGRESS;
    public MyClass () {...}
    (...)
    PROGRESS = (...);
    (...)
    PROGRESS = (...);
    (...)
}

and get MyClass.PROGRESS

Also, don't forget to reset PROGRESS variable after the full completion so that every time you create another JFrame from the same class you get a clean progress from 0.
