hi,
I have a demo program like this, but always finished immediately, I
don't know why, would you like to help me? thanks in advance!
Below is the demo:
package advancedWidget;
import org.eclipse.swt.*;
import org.eclipse.swt.widgets.*;
public class ProgressBarDemo1 {
public static Display myDisplay;
public static boolean internalCall = false;
public static void main(String[] args) {
internalCall = true;
myDisplay = new Display();
ProgressBarDemo1 pbd = new ProgressBarDemo1();
pbd.runDemo(myDisplay);
}
public void runDemo(Display display) {
myDisplay = display;
Shell shell = new Shell(display);
shell.setSize(300, 300);
shell.setText("Progress Bar Demo");
ProgressBar progressBar1 = new ProgressBar(shell, SWT.HORIZONTAL);
progressBar1.setMinimum(0);
progressBar1.setMaximum(100);
progressBar1.setBounds(10,10,250,20);
for (int i = 0; i < 100; i++) {
sleep();
progressBar1.setSelection(i);
}
shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
if (internalCall)
display.dispose();
}
/**
*
*/
private void sleep() {
long i = 0;
while (i < 1110000)
i++;
}
}

You need to open the shell.
import org.eclipse.swt.*;
import org.eclipse.swt.widgets.*;
public class ProgressBarDemo1 {
public static Display myDisplay;
public static boolean internalCall = false;
public static void main(String[] args) {
internalCall = true;
myDisplay = new Display();
ProgressBarDemo1 pbd = new ProgressBarDemo1();
pbd.runDemo(myDisplay);
}
public void runDemo(Display display) {
myDisplay = display;
Shell shell = new Shell(display);
shell.setSize(300, 300);
shell.setText("Progress Bar Demo");
ProgressBar progressBar1 = new ProgressBar(shell, SWT.HORIZONTAL);
progressBar1.setMinimum(0);
progressBar1.setMaximum(100);
progressBar1.setBounds(10, 10, 250, 20);
shell.open();
for (int i = 0; i < 100; i++) {
sleep();
progressBar1.setSelection(i);
}
// shell.open();
while (!shell.isDisposed()) {
if (!display.readAndDispatch())
display.sleep();
}
if (internalCall)
display.dispose();
}
/**
*
*/
private void sleep() {
long i = 0;
while (i < 1110000)
i++;
}
}
